2/5
Weak
evidence
Body composition evidence brief
Chromium picolinate
Weight-loss effects are small and clinically unpersuasive, and resistance-training trials do not support muscle or strength claims.
Headline Finding
Cochrane and NIH reviews describe small weight effects; resistance-training trials do not show body-composition advantage.
Dose Context
Products commonly use microgram dosing, but higher dose does not turn a small population-level signal into a gym-performance effect.
Important Caveat
Do not frame chromium as a fat burner, glucose hack, or lean-mass supplement for healthy lifters.

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.
