Creatine is one of the most studied and well-characterized supplements in existence. It reliably increases muscle mass and strength, particularly relevant for preventing age-related sarcopenia. Emerging evidence suggests cognitive benefits, especially under stress. At $10-15/month with decades of safety data, creatine is one of the few supplements with a genuinely strong evidence base.

The full evidence review — including the $10/month supplement with decades of safety data and a growing cognitive signal — is in Section 10 (The Supplement Deep-Dive) of The Anti-Longevity Playbook.
