A Sixty and Me report says symptoms commonly attributed to aging, including fatigue, tingling and muscle cramps, can also have treatable causes such as vitamin B12 or iron deficiency. It draws on research about anemia and age-related beliefs, while cautioning that symptoms need medical assessment and should not prompt self-diagnosis or unsupervised supplement use.
A Sixty and Me report argues that fatigue, tingling in the hands or feet and muscle cramps should not automatically be dismissed as part of getting older, because conditions such as nutrient deficiencies may also cause them and can be assessed by a clinician. The article stresses that these symptoms have multiple possible explanations and that readers should not diagnose themselves or begin supplements based on an article.
The report uses anemia as an example of a health problem that becomes more common with age but can still have an identifiable cause. It cites a national survey conducted from 1988 to 1994, whose findings were published in the journal Blood in 2004. The researchers found anemia rates rose after age 50; about one in 10 women aged 65 and older were anemic, with the rate exceeding 20 percent among people aged 85 and older. Most cases were mild, the report says.
In about one third of older people with anemia in that study, researchers identified a nutrient deficiency involving iron, folate or vitamin B12. The article also cites National Institutes of Health information stating that atrophic gastritis, which can reduce absorption of vitamin B12 from food, affects 8 to 9 percent of adults aged 65 and older. The NIH information cited by the report also says metformin and some acid-reducing medicines can affect B12 levels or absorption. Low B12 can be associated with fatigue and nerve symptoms such as numbness and tingling, which may occur even without anemia.
Magnesium is another possible factor discussed in the report. The NIH says older adults, on average, consume less magnesium, absorb less from the gut and lose more through the kidneys; some medications can also affect magnesium. Fatigue and weakness are listed as early signs of deficiency, with numbness, tingling and cramps possible as it worsens. But the report notes that serum magnesium testing has limitations: the NIH says serum levels have little correlation with total-body magnesium, and no single measurement method is considered satisfactory. A test result therefore needs to be interpreted with a person’s symptoms and medical history.
Why Symptom Attribution Matters
Calling a symptom “age” without considering other causes may leave a potentially treatable condition unexplored. The report’s examples show why common does not mean inevitable: anemia and changes in nutrient absorption become more frequent with age, but some cases have causes that clinicians can investigate. That does not mean every episode of fatigue or cramping is a deficiency; the same symptoms can arise for many reasons.
The article also points to a possible effect on how people seek care. It cites a University of Michigan National Poll on Healthy Aging survey of 2,035 adults aged 50 to 80, conducted in December 2019. An analysis published in JAMA Network Open in 2022 found that 81 percent held at least one ageist belief about themselves, including the idea that health problems are simply part of getting older. These beliefs were associated with worse physical and mental health, according to the analysis. The survey captured people at one point in time, however, and cannot establish whether those beliefs contributed to poorer health or whether people in poorer health were more likely to hold them.
For readers, the practical point is to raise persistent or concerning symptoms with a qualified health professional and ask what explanations have been considered. That can support a more informed discussion without assuming either that aging is the cause or that a particular nutrient deficiency is responsible.

Evidence Behind the Aging Claim
The report frames the issue through a line attributed to the Roman playwright Terence in his comedy Phormio: “Senectus ipsa est morbus,” translated in the article as “Old age itself is a disease.” It says the line can function today as a conversation-stopper when someone reports a new symptom. The article’s argument is not that aging has no effects: it acknowledges lasting changes, such as joints wearing and needing more light to read, as well as health problems that become more common with age.
Its central distinction is between an age-related change and an assumption that no further explanation is worth seeking. The anemia figures come from data collected decades ago, while the poll describes beliefs among adults aged 50 to 80 at one point in 2019. Neither source establishes what is causing an individual’s symptoms. The NIH material provides information about possible nutrient-related mechanisms, not a diagnosis for any particular reader.
What Symptoms Cannot Establish
The report does not identify a cause for any individual’s fatigue, tingling or cramps. These symptoms are nonspecific, and the article says a deficiency is only one possible explanation. It also does not provide new clinical research or establish that a particular testing approach is appropriate for every patient.
The anemia figures describe a survey from 1988 to 1994, and the age-belief poll was a snapshot rather than a study that can establish cause and effect. The magnesium discussion also highlights uncertainty in measurement: a serum result may not correspond closely to total-body levels, according to the NIH material cited. Readers should discuss the meaning of any symptoms or test results with a clinician rather than infer a diagnosis or start supplements on their own; supplements can interact with medicines or cause harm at inappropriate amounts.
Questions for a Clinical Visit
The report recommends keeping the discussion with a health professional open rather than settling on age as the explanation. Readers can ask what supports that conclusion, what other causes have been considered, whether medicines could affect nutrient levels and what a proposed test would—and would not—show. If a symptom is judged to be age-related, the article suggests asking what care might ease it or slow its effects.
No new study, clinical guideline or official policy change is announced in the report. The next step for someone with symptoms is an individualized medical conversation, where a qualified professional can consider the person’s history, medications and test results. The article explicitly warns against self-diagnosis and unsupervised supplements.
Key Questions
Does fatigue mean I have a vitamin B12 or magnesium deficiency?
No. Fatigue has many possible causes, and the report presents nutrient deficiencies as examples, not diagnoses. A clinician can assess symptoms and decide whether testing or other evaluation is appropriate.
Can tingling or cramps be caused by aging?
Age-related changes can affect health, but the report says tingling and cramps may also have other explanations, including nutrient deficiencies or medication effects. Symptoms alone do not establish their cause.
Does a normal magnesium blood test rule out low magnesium?
The report cites NIH information saying serum magnesium has little correlation with total-body magnesium and that no single measurement method is considered satisfactory. A clinician can interpret a result in light of symptoms and medical history.
Should I start a supplement if I have these symptoms?
The report advises against starting supplements without medical guidance. Supplements may interact with medications or cause harm in the wrong amount; discuss symptoms and possible testing with a qualified health professional.
