Here is the evidence.* ## Why creatine matters for aging **Creatine monohydrate** buffers cellular energy (ATP). Beyond strength, randomized trials show it helps older adults preserve muscle mass and may support cognition under stress. It is cheap, safe, and exceptionally well studied — a rare combination in the longevity space. ## Creatine supplements, graded Linked to mechanism and PubMed citations. | Product | Evidence grade | Citations | Typical price | Why it is on this list | | --- | --- | --- | --- | --- | | [Creatine Monohydrate](https://magellanlongevity.com/p/123.md) | Strong evidence | 23 | $44.00 | Across meta-analyses and randomized trials, creatine monohydrate combined with resistance training modestly increases… | ## Evidence detail ### Creatine Monohydrate - **Evidence grade:** Strong evidence - **Dose used in studies:** 3–5 g/day (creatine monohydrate); an optional ~20 g/day loading week works faster but isn’t required - **What the grade does not say:** One of the most studied supplements there is: dozens of randomized trials and meta-analyses show reliable gains in strength, power and lean muscle alongside resistance training, and it is well tolerated in healthy people. The strong evidence is for muscle and exercise performance; cognitive, bone and healthy-aging benefits are promising but less settled. It supports training — it is not a treatment. ## Frequently asked questions ### Is creatine good for aging? Yes — trials show creatine plus resistance training helps older adults preserve muscle and strength, and it is being studied for brain aging. ### What is the creatine dose? A common protocol is 3–5 g/day of creatine monohydrate, with or without an optional loading phase. ### Is creatine safe? Creatine monohydrate is one of the most-studied supplements and is well tolerated in healthy adults; check with your physician if you have kidney disease. ### Does creatine help the brain? Some trials show cognitive benefits, especially under sleep deprivation or in vegetarians; evidence is promising but still developing. ## The research behind these picks Primary peer-reviewed sources for the products above.
