Recovery hype, adaptation caution recovery / health 5 linked sources Content audit 2026-05-04

Headline Finding

Meta-analyses and RCTs show no dependable recovery benefit and possible interference with adaptation signaling.

Dose Context

Food-level vitamin intake is different from chronic high-dose pills near key training sessions.

Important Caveat

Do not frame antioxidant megadosing as universally recovery-positive; timing, dose, and training phase matter.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
