Longevity Supplements: What the Evidence Actually Says
A grounded look at the most-discussed longevity supplements — and where the science currently stands.
Supplements can't replace lifestyle. But several have meaningful evidence as adjuncts when food and habits are already in place.
Vitamin D
Deficiency is common and clearly linked to worse outcomes. Test and supplement to a healthy range under guidance.
Omega-3 (EPA/DHA)
Lowers triglycerides and supports brain and cardiovascular health, particularly if dietary fish is low.
Creatine
Best-studied supplement for muscle and emerging evidence for cognition in older adults.
Magnesium
Supports sleep, blood pressure, and muscle relaxation in those who are low.
Where evidence is thinner
NMN, NR, and most 'anti-aging' compounds remain promising but unproven for healthspan in humans.

Frequently asked questions
+Do I need a multivitamin?
If your diet is consistently nutrient-dense, probably not. A targeted approach to deficiencies works better than blanket supplementation.
