Best Anti-Aging Supplements

Omega-3 has the most support here, with astaxanthin, collagen and CoQ10 next. The NAD boosters the anti-aging market runs on are where the sources split. Here's what each one does.

Do the anti-aging supplements you're sold work? NMN, NAD boosters, resveratrol, rapamycin. Read across every source, the pattern is stark: the cheap, boring basics have the most support, and the hyped longevity molecules have the least. This page covers those compounds. For the whole-body healthspan picture, see the longevity stack. (We don't sell any of them.)

What Actually Holds Up

Before the exotic molecules, here is what has support:

  • Omega-3 (EPA/DHA) - the best-supported longevity compound here; one target is an omega-3 index of 8-12%
  • Glycine - taken nightly in some regimens for sleep, and a building block for collagen and glutathione
  • Astaxanthin - one of only two over-the-counter compounds the ITP found extended lifespan in male mice
  • CoQ10 - a mitochondrial-energy staple for ATP production
  • The hyped molecules come last for a reason: NMN/NAD, metformin and rapamycin all carry real human-evidence gaps; see the mistakes below

Common Mistakes

  1. Buying NMN or NAD boosters expecting age reversal. The sources split on whether raising NAD slows aging, and the skeptical view calls it noise. Human trials are small, with mixed and often statistically insignificant results. And it remains an open question whether oral NMN raises NAD at all.
  2. Treating resveratrol as proven. It failed to extend lifespan in the ITP studies, and it's the molecule that launched the whole category.
  3. Self-prescribing rapamycin or metformin for longevity. Both are prescription drugs with almost no human longevity evidence. Metformin may also act as a mitochondrial toxin in healthy people.
  4. Expecting collagen to do more than skin. About 15g/day has real skin evidence, but whey beats collagen for muscle; it's a low-leucine protein.
  5. Spending hundreds on molecules while skipping exercise, sleep and protein. Those three carry the strongest evidence.
