Metabolic health evidence brief
Myo-inositol is a vitamin-like compound involved in cell signaling. People usually look at it for PCOS, insulin sensitivity, fertility-adjacent claims, and metabolic-health support.
Myo-inositol may improve some metabolic and reproductive markers in PCOS, but it is not a general body-composition or hormone-balancing supplement.
2023 PCOS guideline review: inositol could be considered by preference, with limited harm and possible metabolic improvements but limited clinical benefits.
PCOS trials often use gram-level daily dosing, sometimes combined with D-chiro-inositol; exact form and ratio remain unresolved.
Use should follow a PCOS diagnosis and broader care plan. Evidence is not strong enough to promise body-composition, fertility, or cosmetic outcomes.

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.
