-
"Optimal 40:1 myo-to-D-chiro ratio"
40:1 ratio is evidence-based for PCOS treatment in multiple clinical trials. This formulation is correctly dosed.
PubMed: Inositol ratio studies in PCOS -
"Third-party tested for purity and potency"
ISO 17025 certified testing is a legitimate quality standard. This is a genuine green flag for supplement safety.
-
"Promotes menstrual cycle regularity and skin health"
Clinical trials show inositol improves PCOS fertility markers and insulin sensitivity. No evidence supports skin health claims.
PubMed: Myo-inositol PCOS meta-analysis (2023) -
"Vitamin D3 and zinc support hormonal balance"
Product page does not disclose doses of vitamin D3 or zinc, making it impossible to verify if amounts are therapeutic.

Based on: Myo-Inositol, D-Chiro Inositol
