Magnesium glycinate supplements vary in serving size, capsule count, and how clearly they state elemental magnesium, so comparing label details matters as much as comparing the front-panel milligrams. I’d put Thorne Magnesium Glycinate first for a straightforward, focused formula, with Nature Made’s 200 mg per serving, 180-capsule bottle as a practical choice for shoppers who want a larger supply and Pure Encapsulations’ 90-capsule bottle for those who prefer a smaller premium-brand option. The main tradeoffs are the amount of elemental magnesium per serving, the number of capsules needed, and whether you want a single-ingredient product or added vitamins. Larger bottles can reduce repurchasing but are a poor fit if you are still deciding whether a supplement suits you. Read on for the full comparison, selection criteria, and advice on matching a label to your routine.

Key Takeaways
- Thorne leads the roundup for shoppers who want a focused glycinate product without added vitamins; its shorter 90-capsule supply may not suit those prioritizing fewer restocks.
- Nature Made’s 200 mg, 180-capsule bottle offers a larger supply than the same brand’s 60-capsule version, while keeping the stated serving amount consistent.
- Pure Encapsulations appears in three bottle sizes, giving shoppers a way to choose between a smaller commitment and a larger supply without changing the named formulation.
- Several listings emphasize figures such as 400 mg or 500 mg, but those numbers are not necessarily the same as elemental magnesium; compare the Supplement Facts serving details before choosing.
- The lineup includes both single-ingredient products and formulas with B6 and D3, so buyers should decide whether they want a simpler formula or have a specific reason to include additional vitamins.

More Details on Our Top Picks
Thorne Magnesium Glycinate, Chelated Magnesium Supplement, 90 Capsules
Thorne stands out for its third-party testing and a clear focus on magnesium glycinate, making it a fit for buyers who put quality checks ahead of a stated dose. The description links the glycine form with relaxation and restful sleep, but it gives no magnesium amount per capsule, so I can’t compare its dose directly with Nature Made Magnesium Glycinate 200 mg per Serving. That makes serving planning less straightforward. The 90-capsule bottle is also smaller than Nature Made’s 180-count option, which spells out a 90-day supply. I’d choose Thorne when independent testing is the deciding feature and the dose can be confirmed on the label; buyers who need dose transparency or a clearly stated supply length may prefer Nature Made.
Pros:- Uses magnesium glycinate, a chelated form
- Third-party tested for purity and label accuracy, according to the supplied details
- The product description identifies sleep and muscle relaxation as intended areas of support
Cons:- No specific magnesium dose per capsule or serving is provided
- The 90-capsule count gives less supply information than Nature Made’s stated 90-day bottle
Best for: Buyers who prioritize third-party testing and are comfortable checking the label for the amount per serving
Not ideal for: Dose-focused shoppers who want the magnesium amount and serving duration stated in the product details
- Brand:Thorne
- Form:Capsules
- Count:90 capsules
- Magnesium form:Magnesium glycinate
- Testing:Third-party tested
- Product focus:Sleep, relaxation, and muscle support
Our verdict“Choose Thorne if third-party testing matters more to you than having a dose and supply duration spelled out in the product details.”
Pure Encapsulations Magnesium Glycinate, 90 Capsules
Pure Encapsulations is the clearest fit for buyers avoiding common allergens, artificial ingredients, and GMOs. Its glycinate formula is described as supporting relaxation, sleep, heart health, and nutrient metabolism, while the supplied details give no dose per serving. That omission makes it harder to compare directly with Nature Made Magnesium Glycinate 200 mg per Serving, which states both its serving size and magnesium amount. Pure’s 90-capsule count matches Thorne’s bottle size, but Thorne lists third-party testing while Pure’s differentiator is its ingredient exclusions. I’d pick Pure when those exclusions shape the purchase; shoppers who want an explicit dose or a longer stated supply should look at Nature Made instead.
Pros:- Magnesium glycinate is the listed key ingredient
- Formulated without common allergens, according to the supplied details
- GMO-free and made without artificial ingredients
- The description names relaxation and sleep-cycle support among its intended uses
Cons:- No magnesium amount per serving is stated in the supplied product information
- The 90-capsule count does not specify how long the bottle lasts
- Does not list the third-party testing detail provided for Thorne
Best for: People who avoid common allergens, GMOs, and artificial ingredients when choosing a magnesium glycinate supplement
Not ideal for: Shoppers comparing products by stated magnesium dose or serving duration, since neither is provided here
- Brand:Pure Encapsulations
- Form:Capsules
- Count:90 capsules
- Key ingredient:Magnesium glycinate
- Allergen information:Free from common allergens
- GMO information:GMO-free
- Artificial ingredients:None listed
Our verdict“Pick Pure Encapsulations if avoiding listed ingredient categories is your priority and you can confirm the serving dose on its label.”
Nature Made Magnesium Glycinate 200 mg per Serving, 180 Capsules
Nature Made earns the overall spot through unusually clear serving details: two capsules provide 200 mg, and the 180-count bottle is described as a 90-day supply. That makes it easier to plan than Thorne or Pure Encapsulations, whose supplied details omit a specific dose. The glycinate is described as chelated, and the product is gluten-free, has no added colors or artificial flavors, and is USP Verified for ingredients, potency, and manufacturing process. The tradeoff is the two-capsule daily serving; NatureBell’s one-a-day format is simpler, though its listed elemental magnesium is 90 mg per serving. I’d choose Nature Made for a stated dose and verification details, while anyone prioritizing a single capsule should compare the serving amounts carefully.
Pros:- States 200 mg of magnesium per two-capsule serving
- 180 capsules are specified as a 90-day supply
- USP Verified for ingredients, potency, and manufacturing process
- Gluten-free, with no added colors or artificial flavors
Cons:- Requires two capsules per serving
- The supplied information does not state magnesium per individual capsule
- Product details include the standard disclaimer that supplement statements are not FDA-evaluated
Best for: Adults who want a clearly stated magnesium amount, serving size, and verified manufacturing information
Not ideal for: People who strongly prefer a one-capsule daily routine or need the amount in a single capsule
- Brand:Nature Made
- Form:Capsules
- Serving size:2 capsules
- Magnesium per serving:200 mg
- Count:180 capsules
- Supply duration:90 days
- Magnesium form:Glycinate (chelated, bisglycinate)
- Dietary details:Gluten-free; no added colors or artificial flavors
- Verification:USP Verified
Our verdict“Choose Nature Made if you want a stated 200 mg serving and USP verification and are fine taking two capsules daily.”
Double Wood Magnesium Glycinate 400mg, 180 Capsules
Double Wood’s main draw is its 180-capsule bottle and stated six-month supply, giving it a longer listed run than Nature Made’s 90-day bottle. The product describes 400 mg of magnesium bisglycinate per capsule, but that figure is for the compound; the supplied details also note that it yields less elemental magnesium. Buyers should check the label for the elemental amount before treating 400 mg as comparable to Nature Made’s stated 200 mg of magnesium per serving. Double Wood lists U.S. manufacturing and testing, Non-GMO and gluten-free status, and testing for microbes and heavy metals in its supplied details. I’d favor it for bottle longevity, while Nature Made is easier to compare by stated magnesium per serving.
Pros:- 180-capsule bottle is described as a six-month supply
- Uses magnesium bisglycinate, a glycinate form
- Non-GMO and gluten-free
- Product details report testing for microbes and heavy metals
Cons:- The 400 mg figure refers to magnesium bisglycinate, not the elemental magnesium amount
- Elemental magnesium per serving is not specified in the supplied details
- The six-month supply depends on the stated serving routine
Best for: Routine supplement users who want a 180-capsule bottle with a stated six-month supply and will verify elemental magnesium on the label
Not ideal for: Dose-comparison shoppers who may mistake 400 mg of bisglycinate compound for elemental magnesium
- Brand:Double Wood
- Form:Capsules
- Count:180 capsules
- Compound amount:400 mg magnesium bisglycinate per capsule
- Supply length:6 months
- Dietary details:Non-GMO and gluten-free
- Manufacturing:Made and tested in the USA from globally sourced ingredients
- Testing:Product details report testing for microbes and heavy metals
Our verdict“Choose Double Wood for its stated six-month bottle supply if you confirm the elemental magnesium amount before comparing doses.”
NatureBell Pure Magnesium Glycinate 500mg, 240 Veggie Capsules
NatureBell pairs a one-capsule-a-day routine with a 240-count bottle, a practical difference from Nature Made’s two-capsule serving. The supplied details say each serving contains 500 mg of chelated magnesium compound, including 90 mg elemental magnesium; those are different measures, so buyers comparing it with Nature Made’s stated 200 mg per serving should focus on elemental amounts and serving directions. Its veggie capsules and no-fillers claim may suit shoppers seeking a plant-based format with a long stated supply of up to eight months. The tradeoff is that 90 mg elemental magnesium per serving is the clear dose figure here, and the larger 500 mg compound number can obscure that distinction. I’d choose NatureBell for routine simplicity, not for the highest stated elemental amount.
Pros:- One capsule per day is the stated format
- 240 veggie capsules, with a supply of up to eight months
- Provides 90 mg elemental magnesium per serving in the supplied details
- Listed as free from fillers
Cons:- The 500 mg compound figure is not the elemental magnesium amount
- The stated elemental magnesium is 90 mg per serving, lower than Nature Made’s 200 mg per serving
- Product details state that supplement claims have not been evaluated by the FDA
Best for: Buyers who prefer a veggie capsule, a one-a-day routine, and a long bottle supply
Not ideal for: Shoppers seeking a higher stated elemental magnesium amount per serving or who compare products by the larger compound-weight figure
- Brand:NatureBell
- Form:Veggie capsules
- Count:240 capsules
- Compound amount:500 mg per serving
- Elemental magnesium:90 mg
- Supply duration:Up to 8 months
- Additives:No fillers
- Serving routine:One capsule per day
Our verdict“Pick NatureBell if one-a-day convenience and veggie capsules matter more to you than a higher stated elemental magnesium amount.”
NatureBell Pure Magnesium Glycinate 500mg, 2-Pack (480 Capsules)
The 480-capsule, two-pack supply makes this NatureBell option a fit for shoppers who already know they want a long-term magnesium glycinate routine. Its listed serving is one capsule, while Nutricost Magnesium Glycinate requires three capsules to provide its stated 210 mg of magnesium per serving. NatureBell also lists 40 mg of vitamin C and third-party lab testing, giving buyers a different formula and quality-check profile. The tradeoff is that the description does not clarify how much elemental magnesium the 500 mg figure represents, so buyers comparing actual magnesium amounts should check the label carefully. The unusually large supply can also be cumbersome if you want to try the formula for a shorter period, and vitamin C may be an unnecessary extra for shoppers seeking magnesium alone.
Pros:- One capsule per listed serving
- 480 capsules across two packs
- Vegan capsules and listed freedom from several common allergens
- Includes 40 mg of vitamin C and third-party lab testing
Cons:- Large quantity may be excessive for a short-term trial
- The supplied product data does not state elemental magnesium content
- Vitamin C makes the formula less suitable for buyers seeking magnesium alone
Best for: Experienced supplement users who want a one-capsule serving and a large vegan supply.
Not ideal for: First-time buyers or anyone who wants a short trial or a clearly stated elemental magnesium amount before choosing.
- Form:Capsule
- Serving size:1 capsule
- Magnesium glycinate:500 mg per serving
- Vitamin C:40 mg
- Total count:480 capsules
- Pack size:2 packs
- Dietary information:Non-GMO, non-irradiated, vegan
- Testing:Third-party lab tested
Our verdict“Choose this NatureBell two-pack if you want a one-capsule serving and a long supply, and confirm the elemental magnesium amount on the label first.”
Nutricost Magnesium Glycinate Capsules, 180 Capsules, 210mg
Nutricost spells out the serving math: three capsules provide 210 mg of magnesium from magnesium bisglycinate. That clarity helps buyers compare it with VITBOOST Magnesium Glycinate, which lists 500 mg of glycinate and 90 mg of elemental magnesium per capsule. The tradeoff is a three-capsule serving, so this is less convenient than single-capsule options such as the NatureBell 2-Pack. Nutricost pairs its serving information with third-party testing and manufacturing in an NSF certified GMP compliant facility, which may appeal to shoppers who prioritize those details. Its 180-capsule bottle provides 60 servings; the supplied product data does not specify whether the 210 mg is elemental magnesium, so check the product label if that distinction affects your comparison.
Pros:- States 210 mg of magnesium per three-capsule serving
- Uses magnesium bisglycinate
- Third-party tested
- Manufactured in an NSF certified GMP compliant facility
Cons:- Requires three capsules per serving
- Supplied product data does not identify the 210 mg as elemental magnesium
- The 180-capsule bottle provides 60 servings
Best for: Label-focused buyers who want a stated 210 mg serving and are comfortable taking three capsules.
Not ideal for: People who dislike multi-capsule servings or need a product whose supplied details clearly identify elemental magnesium.
- Form:Magnesium bisglycinate capsules
- Serving size:3 capsules
- Magnesium per serving:210 mg
- Capsule count:180
- Servings per container:60
- Manufacturing:NSF certified GMP compliant facility
- Testing:Third-party tested
Our verdict“Pick Nutricost if its stated serving amount and testing details matter more to you than taking fewer capsules.”
Magnesium Glycinate 500mg with Vitamin B6 & D3 – Sleep, Muscle & Heart Support – 120 Capsules
This is the lineup’s add-on-heavy pick: each daily capsule combines magnesium glycinate with vitamins B6 and D3 and black pepper. That may suit buyers who prefer these ingredients together, while VITBOOST Magnesium Glycinate keeps its listed formula simpler and Nature’s Bounty High Absorption Magnesium Glycinate also avoids the same added-ingredient mix in the supplied description. The 90 mg elemental magnesium per serving is stated explicitly, a useful distinction from the 500 mg glycinate figure. That amount may be lower than some buyers expect from the headline number, so compare elemental amounts rather than the glycinate weight alone. The added nutrients also make it less appealing if you want to manage each supplement separately or already take B6 or D3.
Pros:- One capsule daily
- States both 500 mg magnesium glycinate and 90 mg elemental magnesium per serving
- Includes vitamins B6 and D3 plus black pepper
- Third-party lab tested and made in a GMP-certified facility
Cons:- Provides 90 mg elemental magnesium per serving despite the 500 mg glycinate headline
- Added ingredients may overlap with an existing supplement routine
- Not suited to buyers who want to adjust magnesium separately from B6 and D3
Best for: Buyers who want one daily capsule combining magnesium glycinate with B6, D3, and black pepper.
Not ideal for: Shoppers seeking magnesium alone or those who want a higher stated elemental magnesium amount per serving.
- Form:Capsule
- Serving size:1 capsule daily
- Magnesium glycinate per serving:500 mg
- Elemental magnesium per serving:90 mg
- Count:120 capsules
- Additional ingredients:Vitamin B6, vitamin D3, black pepper
- Testing and manufacturing:Third-party lab tested; GMP-certified facility
- Free from:Sugar, soy, GMOs, artificial colors, fragrances, and preservatives
Our verdict“Choose this formula if you want magnesium alongside B6 and D3 in one capsule and are comfortable with 90 mg of elemental magnesium.”
VITBOOST Magnesium Glycinate 500mg (90mg Elemental) – 120 Veggie Capsules
VITBOOST makes the elemental amount easy to spot: its listed 500 mg of magnesium glycinate supplies 90 mg of elemental magnesium per capsule. That transparency puts it on similar footing with the B6 and D3 formula, which also lists 90 mg elemental magnesium, but VITBOOST does so without those added vitamins or black pepper. Compared with Nutricost’s three-capsule serving, its one-capsule serving is simpler to fit into a daily routine. The tradeoff is that 90 mg may not meet every buyer’s target, and the supplied details do not establish a way to increase the serving without taking multiple capsules. Its vegan, gluten-free description and third-party testing help narrow the choice for buyers with specific preferences, though it offers less formula variety than the combination product.
Pros:- Clearly states 90 mg elemental magnesium per 500 mg glycinate serving
- One veggie capsule per serving
- Vegan, non-GMO, gluten-free, sugar-free, and cruelty-free
- Third-party tested and made in a cGMP facility
Cons:- 90 mg elemental magnesium per capsule may be less than some buyers seek
- Increasing intake may require multiple capsules
- Does not include the B6 and D3 found in the combination formula
Best for: Vegan shoppers who want one capsule per serving and a clearly stated elemental magnesium amount.
Not ideal for: Buyers seeking a larger elemental magnesium amount in one capsule or a formula with added B6 or D3.
- Form:Veggie capsules
- Serving size:1 capsule
- Magnesium glycinate:500 mg per serving
- Elemental magnesium:90 mg per serving
- Quantity:120 capsules
- Supply duration:4 months
- Dietary information:Vegan, non-GMO, gluten-free, sugar-free, cruelty-free
- Origin and testing:Made in USA; third-party tested; cGMP
Our verdict“Choose VITBOOST for a clearly labeled, vegan one-capsule option if 90 mg of elemental magnesium suits your needs.”
Nature’s Bounty High Absorption Magnesium Glycinate 240 mg Capsules, 120 Count
Nature’s Bounty keeps the formula straightforward with magnesium glycinate and a two-capsule daily serving that provides 240 mg of magnesium. The 120-capsule bottle is listed as a two-month supply, a more manageable commitment than the NatureBell two-pack’s 480 capsules. Compared with VITBOOST, the supplied details do not break out elemental magnesium, so buyers who compare products by that figure should verify it on the label. Its vegetarian, non-GMO, gluten-free, and lactose-free description will suit shoppers who want a simple dietary profile, but the two-capsule serving is less convenient than VITBOOST’s one capsule. The product data also gives fewer specifics about testing or manufacturing than Nutricost, which may matter to buyers seeking those assurances.
Pros:- Provides 240 mg magnesium per two-capsule serving
- 120 capsules are listed as a two-month supply
- Vegetarian and non-GMO
- Listed as gluten-free and lactose-free, with no sugar or sodium
Cons:- Requires two capsules per day
- Supplied product data does not state elemental magnesium content
- Supplied details do not specify third-party testing
Best for: Shoppers who prefer a familiar brand, a two-capsule serving, and a moderate bottle size.
Not ideal for: Buyers who require elemental magnesium disclosure in the supplied details, a one-capsule serving, or specific third-party testing information.
- Brand:Nature’s Bounty
- Form:Capsules
- Magnesium amount:240 mg per serving
- Serving size:2 capsules per day
- Count:120 capsules
- Supply duration:2 months
- Magnesium form:Magnesium glycinate
- Dietary information:Vegetarian, non-GMO, gluten-free, lactose-free; no sugar, sodium, artificial colors, or sweeteners
Our verdict“Pick Nature’s Bounty if you want a straightforward two-capsule glycinate routine in a moderate-size bottle and do not need the supplied details to state elemental magnesium.”
Nature Made Magnesium Glycinate 300 mg, 90 Capsules
Nature Made’s 300 mg serving sets it apart from the brand’s 200 mg option, which may suit shoppers who want a lower listed amount per serving. The tradeoff is the routine: reaching 300 mg takes three capsules daily, rather than two with the 200 mg formula. Its bisglycinate form and gentle-on-the-stomach positioning make it a straightforward pick for people who prioritize that form, while USP Verified provides a named quality check that is not listed for Nobi Nutrition’s 500 mg product. It is also gluten-free and has no artificial colors or flavors. The supplied data does not state the amount of elemental magnesium, so I would not compare the 300 mg figure directly with products that specify elemental magnesium.
Pros:- USP Verified
- Bisglycinate form is positioned as gentle on the stomach
- Gluten-free with no artificial colors or flavors
- 300 mg listed per three-capsule serving
Cons:- Requires three capsules per day
- The supplied product data does not specify elemental magnesium
- No serving schedule beyond the three-capsule amount is provided
Best for: Adults who prefer a higher stated serving amount and value USP verification, and are comfortable taking three capsules daily.
Not ideal for: People who want a one- or two-capsule routine, or need a clearly stated elemental magnesium amount to compare formulas.
- Brand:Nature Made
- Form:Capsules
- Magnesium form:Magnesium bisglycinate
- Amount per serving:300 mg per 3 capsules
- Count:90 capsules
- Supply:30 days
- Dietary details:Gluten-free; no artificial colors or flavors
- Verification:USP Verified
Our verdict“Choose this Nature Made formula if USP verification and a 300 mg stated serving matter more to you than keeping the daily capsule count low.”
Nature Made Magnesium Glycinate 200 mg per Serving, 60 Capsules
Two capsules for a 200 mg serving give this Nature Made bottle a simpler daily routine than its sibling’s 300 mg serving, which takes three capsules. That makes it a practical fit for someone who wants the brand’s chelated glycinate formula without committing to as many capsules at once. It is described as gentle on the stomach and is gluten-free, with no artificial flavors or added color. Compared with Pure Encapsulations Magnesium Glycinate, 180 Capsules, this listing gives a serving amount, making the daily amount easier to interpret from the provided data; Pure Encapsulations lists no dosage here. The 60-capsule bottle is specified as a 30-day supply, so it offers less total supply than larger-count alternatives.
Pros:- Lists 200 mg per two-capsule serving
- Chelated magnesium glycinate form
- Gluten-free, with no artificial flavors or added color
- Stated 30-day supply makes the bottle duration clear
Cons:- Requires two capsules daily
- 60 capsules provide a shorter supply than larger-count options
- The supplied data does not specify elemental magnesium
Best for: Adults seeking a clearly stated 200 mg serving in a two-capsule daily routine and a modest bottle size.
Not ideal for: Shoppers who want a longer-lasting bottle or who prefer a single capsule per serving.
- Brand:Nature Made
- Form:Capsules
- Magnesium per serving:200 mg
- Serving size:2 capsules daily
- Directions:Take with water and a meal
- Magnesium form:Chelated magnesium glycinate (bisglycinate)
- Count:60 capsules
- Supply:30 days
- Dietary details:Gluten-free; no artificial flavors; no color added
Our verdict“Pick this version for a clearly listed 200 mg serving and two-capsule routine, especially if a smaller bottle suits your needs.”
Magnesium Glycinate 500mg High Absorption Supplement
Vegan, gluten-free, and non-GMO credentials give Nobi Nutrition a distinct place among these picks, particularly for shoppers filtering by dietary preferences. The product lists 500 mg per serving and describes its capsules as small and easy to swallow, a useful counterpoint to Nature Made’s 300 mg serving, which requires three capsules. It also names GMP certification and third-party testing, while the supplied Nature Made listing specifies USP verification instead. Those quality markers are not interchangeable, and the provided data does not explain the testing scope. The serving size and elemental magnesium amount are also unspecified, so the 500 mg figure is difficult to compare directly with Nature Made’s stated per-serving amounts. I would choose it for the dietary fit, while checking the label for serving details.
Pros:- Listed as vegan, gluten-free, and non-GMO
- Described as small and easy to swallow
- GMP-certified and third-party tested, according to the supplied data
- 500 mg stated per serving
Cons:- Serving size is not provided
- Elemental magnesium amount is not specified
- Testing scope and certification details are not described
Best for: Vegan shoppers who want a glycinate capsule with stated gluten-free and non-GMO attributes and third-party testing claims.
Not ideal for: Buyers who need the exact capsule count per serving or a clearly specified elemental magnesium amount before comparing doses.
- Brand:Nobi Nutrition
- Form:Capsules
- Amount per serving:500 mg
- Magnesium form:Chelated magnesium glycinate
- Dietary details:Vegan, gluten-free, non-GMO
- Quality claims:GMP-certified; third-party tested
- Capsule description:Small and easy to swallow
Our verdict“Consider Nobi Nutrition if its vegan and dietary claims are your priority, but verify the serving and elemental magnesium details on the label.”
Pure Encapsulations Magnesium Glycinate, 180 Capsules
Allergen-conscious formulation is the clearest reason to choose this Pure Encapsulations bottle: the supplied data says it is free from common allergens, artificial ingredients, and GMOs. Its 180-capsule count is also between the 90-capsule Nature Made 300 mg bottle and the 360-capsule Pure Encapsulations option, offering a middle ground in bottle size. But unlike Nature Made’s 200 mg listing, this product data gives no dosage per capsule or serving. That makes it harder to estimate how long the bottle will last or compare magnesium amounts. The description mentions relaxation, sleep-cycle support, and nutrient metabolism, but it does not provide dosage details to help interpret those claims. This pick makes the most sense when ingredient exclusions matter more than dose transparency.
Pros:- Free from common allergens, artificial ingredients, and GMOs, according to the supplied data
- 180-capsule bottle offers a mid-size count within this lineup
- Glycinate form is specified
- Description identifies relaxation and sleep-cycle support as intended uses
Cons:- No dosage per capsule or serving is provided
- Supply duration cannot be determined from the listed information
- No testing or verification credential is included in the supplied data
Best for: Buyers who prioritize avoiding common allergens, artificial ingredients, and GMOs and are prepared to check the full label for dosing.
Not ideal for: Dose-focused shoppers who want a stated amount per capsule or serving before choosing a bottle.
- Brand:Pure Encapsulations
- Form:Capsules
- Count:180 capsules
- Key ingredient:Magnesium glycinate
- Dosage:Not specified in the supplied data
- Dietary details:Free from common allergens, artificial ingredients, and GMOs
- Listed support:Heart health, bone density, energy production, relaxation, and sleep-cycle support
Our verdict“Choose this Pure Encapsulations bottle if ingredient exclusions matter most and you can confirm the dose from its label.”
Pure Encapsulations Magnesium (Glycinate), 360 Capsules
360 capsules make this the largest-count option in this batch, suited to buyers who would rather keep a larger bottle on hand. Compared with Pure Encapsulations Magnesium Glycinate, 180 Capsules, it doubles the count, but the supplied information still does not state a serving size or magnesium amount. That means the larger bottle does not reveal how many days it will last, and it is harder to compare its dose with Nature Made’s 200 mg per-serving product. The formula is listed as glycinate and free from common allergens, artificial or unnecessary ingredients, and GMOs. Those exclusions may appeal to ingredient-conscious shoppers, but the listing provides no verification credential or dose details to support a more precise comparison. Check the label before deciding based on capsule count alone.
Pros:- 360-capsule count is the largest in this batch
- Magnesium type is listed as glycinate
- Described as free from common allergens, artificial or unnecessary ingredients, and GMOs
- Description also lists support for heart health, energy production, and bone health
Cons:- Magnesium amount per capsule or serving is not specified
- Serving size and supply duration are not provided
- No testing or verification credential is listed in the supplied data
Best for: Buyers who prefer a high capsule count and want a glycinate formula described as free from common allergens, artificial ingredients, and GMOs.
Not ideal for: Shoppers who need a known magnesium amount, serving size, or supply duration to compare products confidently.
- Brand:Pure Encapsulations
- Form:Capsules
- Count:360 capsules
- Magnesium type:Glycinate
- Magnesium amount:Not specified in the supplied data
- Dietary details:Free from common allergens, artificial or unnecessary ingredients, and GMOs
- Listed support:Heart health, neuromuscular contractions, cardiac function, energy production, and bone health
Our verdict“Choose this bottle for its large capsule count and stated ingredient exclusions only after confirming the serving size and dose on the label.”
How We Picked
I compared the products on details that affect day-to-day use: how clearly the listing identifies the magnesium amount and serving, whether the formula is focused on glycinate or adds other ingredients, capsule count, and the range of available bottle sizes. I gave more weight to products whose stated serving information makes side-by-side comparison easier, since front-label milligram figures can describe different things. I also considered whether a product’s format suits a first purchase, a regular routine, or someone seeking a larger supply.
The order favors clear, focused options with useful serving and bottle-size choices. Thorne ranks first as a simple starting point; Nature Made’s larger 200 mg bottle follows for shoppers who want more capsules in one purchase. Pure Encapsulations earns a premium-oriented place, while products with less detail in their supplied names or added ingredients rank lower because buyers have more label questions to resolve. These rankings compare product information, not clinical results, and a label alone cannot establish that a supplement is right for an individual.

Factors to Consider When Choosing Magnesium Glycinate Supplements
Before choosing a bottle, I’d match the label to your intended serving, tolerance for capsules, and how certain you are that this formula fits your routine. These checks can help you compare products that use similar names but present their amounts and extras differently.

Do not assume a large number on the front is the amount of magnesium you will get from a serving. The compound weight and elemental magnesium amount can differ, so check the Supplement Facts panel for the declared magnesium amount per serving. Also note how many capsules make up that serving; a number that looks comparable may require more capsules. This is a common source of confusion when comparing products labeled 400 mg or 500 mg. Use the serving facts, rather than the front label alone, for a like-for-like comparison. If the listing does not make the amount clear, check the product label before buying.
Choose a serving you can follow
A supplement is only practical if its serving fits your habits. Check capsule size if that tends to affect what you can take comfortably, and count the capsules per serving rather than only the capsules in the bottle. A higher capsule count does not always mean a longer supply if each serving calls for several capsules. When comparing options, divide the total capsule count by the labeled capsules per serving to estimate servings per bottle. That simple calculation can reveal why two bottles with similar counts may last different lengths of time. Follow the label directions and ask a healthcare professional if you are unsure what serving is appropriate for you.
Decide whether added vitamins belong in your formula
Some products in this roundup pair glycinate with vitamins B6 and D3, while many others are presented as magnesium-focused formulas. Added ingredients can be convenient if you already want those nutrients in the same product, but they make it harder to adjust each supplement separately. They can also duplicate nutrients in a multivitamin or another product you already take. Check the full ingredient panel and serving amounts before combining supplements. If you prefer to know which ingredient is responsible for an effect or unwanted response, a simpler formula is easier to track. Choose added vitamins for a clear reason, not just because the front label lists more ingredients.
Match bottle size to how sure you are
A large bottle or multipack can be convenient once you have settled on a product, but it commits you to more of the same formula. For a first purchase, a smaller bottle can make it easier to change course if the capsule format or ingredients do not suit you. The Pure Encapsulations listings illustrate how the same named product is offered in 90-, 180-, and 360-capsule formats. Compare servings per bottle, not just the count printed in the title. Consider storage space and the product’s expiration date as well, especially with a multipack. Repeated use is not automatically a reason to buy the largest available size.
Check the full label and your personal context
Product titles are abbreviated, so confirm the Supplement Facts and other label details before making a decision. Check the serving directions, inactive ingredients, capsule material, and any allergen or dietary statements that matter to you. Supplements can interact with medicines or be unsuitable in some health circumstances, and individual needs vary. Ask a clinician or pharmacist before starting magnesium if you take medication, have a relevant health condition, are pregnant, or are unsure about supplementation. Do not use a product title’s wellness language as a substitute for medical advice. A clear label and a quick professional check can make the choice more appropriate to your situation.
Frequently Asked Questions
How do I compare a product labeled 500 mg with one labeled 200 mg?
Start with each product’s Supplement Facts panel and identify the elemental magnesium amount per serving. The larger number in a product title may refer to the weight of a compound or a different labeling convention, so it cannot be compared directly without the panel details. Check the serving size too, since one product may require more capsules than another. If the listing does not clearly state the amount, verify the packaging before purchase. Comparing elemental amounts and capsules per serving gives you a more useful picture than comparing headline numbers.
Should I buy a large bottle before I know whether I like the formula?
A smaller bottle is usually easier to evaluate if you have not taken that product before or are uncertain about capsule size and ingredients. Larger formats can be convenient for an established routine, but they leave you with more capsules if the formula does not fit your needs. Check the number of servings in each bottle, since capsule count alone can be misleading. Also look at the expiration date and storage directions for a multipack. If a clinician has recommended a particular product or serving, confirm that the larger format matches that guidance.
Is a formula with B6 and D3 better than magnesium glycinate on its own?
Not automatically. Added vitamins may suit someone who has a reason to take them and wants a combined product, but they can duplicate nutrients from other supplements. A single-ingredient formula gives you more flexibility to adjust magnesium separately and makes it easier to identify which product may be causing an unwanted response. Compare the amount of each added nutrient with your other products and the label directions. If you take medication or have a health condition, ask a clinician or pharmacist about the combination before use.
Which bottle size makes sense if I want to try a premium option?
A smaller bottle can be a sensible first step when you are deciding whether a particular capsule format and label suit you. In this roundup, Pure Encapsulations is listed in 90-, 180-, and 360-capsule sizes, so you can compare a shorter commitment with larger supplies of the same named product. Work out the servings from the label before comparing those formats. A bigger bottle is useful only if the serving and formula already fit your routine. Follow the product directions, and check with a healthcare professional if you have questions about taking magnesium.
What should I check if I already take a multivitamin or prescription medicine?
Review the Supplement Facts and ingredient lists for overlapping magnesium, B6, D3, and other nutrients before adding another product. The total across products matters more than the amount in any one bottle. Magnesium supplements may also affect how some medicines are absorbed or used, so timing and suitability can depend on the medication. Ask a pharmacist or clinician to review the specific product and your medication list rather than relying on a product title. This is especially useful if you have a health condition or are unsure whether supplementation is appropriate.
Conclusion
Best overall: I’d start with Thorne for a focused glycinate option. Best value-oriented supply: Nature Made’s 200 mg, 180-capsule bottle gives shoppers a larger format than its 60-capsule counterpart; compare the label and servings before deciding. Best premium: Pure Encapsulations offers multiple bottle sizes, with the 90-capsule version making more sense for a first purchase and larger formats for an established routine. Best for beginners: choose a smaller bottle with a clearly stated serving, such as the 60-capsule Nature Made option, so you can assess the format before committing to more. Best for specific needs: consider the B6 and D3 combination only if those added ingredients fit your plan. Across the lineup, I’d make the final choice by elemental magnesium per serving, capsules required, and the ingredients you actually want.
