Longevity & AgingWhich Supplements Older Adults Actually Need Based on Real Deficiency Risk
As people age, nutritional deficiencies become more common due to reduced appetite, medication use, and changes in digestion. This article breaks down which supplements have genuine evidence behind them for older adults. Vitamin B12 is a standout — stomach acid declines with age, making it harder to absorb B12 from food, and deficiency can cause nerve damage and cognitive issues. Vitamin D also matters when levels are low. Protein is highlighted as an underappreciated priority for maintaining muscle strength and independence. Meanwhile, many popular supplements offer little benefit for those without deficiencies and some carry real risks including toxicity and drug interactions. The core message is to test for actual deficiencies rather than taking supplements preventively.
