The anti-ageing supplement market promises a lot and delivers much less. A few supplements have solid evidence for healthy ageing, mostly by supporting muscle, bone and heart health. Many popular “longevity” products have exciting animal data and very little proof in people. This guide sorts them honestly.
- The best-proven tools against ageing are exercise, strength training, sleep, not smoking and a healthy weight.
- Creatine, vitamin D where deficient, omega-3s and adequate protein have reasonable evidence for specific benefits.
- NMN, NAD+ precursors and resveratrol are promising in animals but unproven for extending human healthspan.
- Supplements are not regulated like drugs; quality varies.
The foundations come first
No supplement comes close to the effect of regular exercise. Strength training preserves muscle and bone, which protects independence and reduces falls. Aerobic fitness is one of the strongest predictors of longevity. Sleep, a diet rich in plants and protein, not smoking and limiting alcohol matter more than anything in a capsule.
Supplements with reasonable evidence
Creatine
Combined with strength training, creatine helps older adults gain more muscle and strength than training alone. It is inexpensive and well studied. See creatine vs steroids.
Protein
Older adults need more protein per meal to stimulate muscle growth. Protein powder can help when appetite is low.
Vitamin D
Correcting a deficiency supports bone health. Taking more when levels are already normal has not shown broad benefits. A blood test tells you which applies.
Omega-3s
Fish oil lowers triglycerides and, in some trials, cardiovascular events in specific groups. Eating oily fish twice a week is a good baseline.
Promising but unproven
| Supplement | Idea | Human evidence |
|---|---|---|
| NMN, NR (NAD+ precursors) | Restore NAD+, which falls with age | Raise NAD+ levels; little proof of health benefit |
| Resveratrol | Activate longevity pathways | Early hype not borne out in human trials |
| Collagen | Support skin and joints | Some small studies on skin and joint pain |
| Spermidine | Promote cellular clean-up | Mostly observational and animal data |
| Epitalon and other peptides | Telomere and longevity claims | Very limited; not approved |
Hormones are not supplements
Testosterone, growth hormone and DHEA are sometimes marketed as anti-ageing. They have real effects and real risks, and should only be used for diagnosed deficiencies under medical supervision. See age and anabolic steroids.
Supplements can interact with prescription drugs, especially blood thinners, diabetes and blood pressure medication. Tell your pharmacist what you take.
Strength is the anti-ageing intervention
After about age 30, adults gradually lose muscle, and the pace picks up after 60. Low muscle strength predicts falls, loss of independence and earlier death. Studies in people well into their 80s show that progressive strength training reverses part of that loss within months. Two or three sessions a week of challenging resistance exercise, with enough protein, outperforms any longevity supplement on the market.
Buying supplements in Canada
Look for a Natural Product Number (NPN) on the label, which shows Health Canada has reviewed the product’s safety and claims. It does not guarantee the product works, but it is a minimum standard.
Where to spend your money
A good pair of training shoes, a gym membership, quality protein and vegetables will do more for healthy ageing than any longevity stack. If you add supplements, start with the ones that have evidence and test for deficiencies rather than guessing.

Frequently asked questions
Does NMN slow ageing?
It raises NAD+ levels in people, but there is no strong evidence yet that it slows ageing or extends life.
Is creatine good for older adults?
Yes, combined with strength training it helps build muscle and strength.
Should I take collagen?
Some small studies suggest skin and joint benefits; protein and strength training matter more.
