Ranked by evidence
Best supplements for healthy aging
For healthy aging, the supplements with real evidence are unglamorous: they lower blood pressure, support muscle and bone, or fix deficiencies that become common with age. Everything below is ranked by the evidence for those outcomes, not by popularity. The popular anti-aging molecules can move a biomarker, but none has improved function or lifespan in human trials.
Picks are ranked by the strength of published evidence for this goal in otherwise healthy adults. A persistent symptom needs a clinician's evaluation, and no supplement on this list replaces treatment.
Evidence last reviewed: September 2026
Top picks
| Option | Evidence | Best for | The honest note | |
|---|---|---|---|---|
| Potassium | Strong evidence | blood pressure and stroke risk | In a trial of 20,995 adults with prior stroke or aged 60+ with hypertension, a potassium-enriched salt substitute reduced stroke and death over about five years. Pills are capped at doses too small to matter, and extra potassium is dangerous with kidney disease or certain blood-pressure drugs. | View |
Solid options
| Option | Evidence | Best for | The honest note | |
|---|---|---|---|---|
| Whey Protein Isolate | Strong evidence | keeping muscle as you age | Combined with resistance exercise, whey improves muscle mass and strength in older adults with sarcopenia. The effect is modest and depends on the training. | View |
| Senior Multivitamin (50+) | Moderate evidence | memory and covering common gaps | In the COSMOS trial programme a daily multivitamin gave a modest benefit on memory and global cognition in older adults. It does not prevent cardiovascular disease. | View |
| Bone Support Formulas | Moderate evidence | lowering fracture risk | Combined calcium and vitamin D reduced total and hip fractures in a meta-analysis, with the largest absolute benefit in older adults with low intakes or in institutional care. Vitamin D alone showed no clear fracture benefit. | View |
| Citicoline (CDP-Choline) | Moderate evidence | memory in healthy older adults | A 12-week trial of 500 mg/day in healthy adults aged 50–85 improved episodic memory versus placebo. It is a single study with industry involvement and needs replication. | View |
Situational
| Option | Evidence | Best for | The honest note | |
|---|---|---|---|---|
| Vitamin B12 | Strong evidence | older adults with poor absorption | Up to 20% of older adults absorb food-bound B12 poorly, and correcting deficiency prevents anaemia and nerve damage. Extra B12 does nothing for energy if your levels are normal. | View |
| Vitamin D3 | Strong evidence | bones, if your level is low | Together with calcium, it reduces fracture risk in older adults with low levels. In people who are not deficient, large trials such as VITAL showed no reduction in cardiovascular events or cancer. | View |
| HMB (β-Hydroxy-β-Methylbutyrate) | Limited evidence | preserving muscle in older adults | Added to exercise in older adults, HMB produced small improvements in muscle mass and some strength measures. It is most useful as an anti-catabolic in older, untrained or clinically compromised people. | View |
| Omega-3 (EPA/DHA) | Moderate evidence | high-risk heart patients | High-dose purified EPA at 4 g/day reduced cardiovascular events in high-risk patients, but low-dose supplements show little or no effect in the general population. | View |
Popular for this goal — but the evidence says skip
- NMN (Nicotinamide Mononucleotide) Limited evidence
It raises blood NAD+, but a meta-analysis found no effect on glucose or lipids, no human trial has measured aging or mortality, and the FDA has ruled it cannot be sold as a supplement in the US.
- Nicotinamide Riboside Limited evidence
It reliably raises NAD+, yet well-controlled trials have failed to improve insulin sensitivity, muscle or physical function.
- Resveratrol Limited evidence
Oral bioavailability is under 1%, no human trial has measured an aging or mortality endpoint, and in older men it blunted training gains.
- Telomere Support Formulas Limited evidence
Pooled trials show longer measured telomeres but no improvement in grip strength, walking or inflammation, and the long-term cancer risk is unstudied.
- Ginkgo Biloba Limited evidence
A trial of 3,069 older adults over a median 6.1 years found it did not slow cognitive decline at all.
- Fisetin Limited evidence
The rigorous NIA Interventions Testing Program found it did not extend lifespan in mice, and no human trial has shown a clinical benefit.
Our verdict
Enough protein alongside resistance training, a potassium-enriched salt substitute if your kidneys and medications allow it, and checking your B12 and vitamin D cover most of what supplements can do. Skip NMN, NR, resveratrol, senolytics and telomere blends, which are sold on biomarkers or mouse data rather than outcomes.
