Optimum Nutrition Micronized Creatine

8.8 / 10 · From ~$30 (120 servings)
8.8

If supplements were graded purely on evidence-per-dollar, creatine monohydrate would top the entire industry - hundreds of studies support modest strength and performance benefits from a boring 3-5g daily. ON's micronized version mixes decently, tests clean, and costs pennies a day. The rare supplement that is exactly what it claims.

Why we rate it

  • Creatine monohydrate is the most-researched performance supplement in existence
  • Single-ingredient label: no proprietary blends, no fairy dust
  • Micronized powder mixes better than bargain-bin creatine

Keep in mind

  • Unflavored means gritty-neutral - most stir it into juice or a shake

Advanced Amino Formula

7.8 / 10 · From $39.95/bottle; $33-36 in multi-packs
7.8

Underneath a very loud sales page sits a fairly sensible product: capsules delivering the essential amino acids - including leucine, the one most studied for triggering muscle protein synthesis - aimed at the very real problem of age-related muscle loss. The honest science: EAA supplementation can help older adults maintain muscle, with the benefit showing up most clearly in people who don't eat enough protein and do at least some resistance exercise; it is a supporting actor, not the 'muscle reversal' miracle the marketing performs. At ~$40 a bottle it costs more than generic EAA powders, capsules are simply more pleasant than chalky drinks, and the 90-day money-back guarantee meaningfully lowers the risk of finding out which camp you're in. Ignore the sales letter, keep the supplement - and keep lifting.

Why we rate it

  • Essential amino acids with leucine are among the better-supported supplement categories for older adults' muscle maintenance
  • Capsule format skips the chalky-shake problem that makes people quit EAA powders
  • Vegan-friendly formulation, and a genuine 90-day money-back guarantee to de-risk trying it

Keep in mind

  • The sales page dramatically oversells - lines like whey protein 'turning into sugar' are misleading framing, not science
