CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelModerate-StrongStrong (PCOS, anxiety), Moderate (general metabolic)

Mechanism

Stable precursor to sulforaphane. Requires myrosinase enzyme (from gut bacteria or co-administered) for conversion. Provides sustained sulforaphane release compared to direct supplementation. Activates Nrf2 pathway for antioxidant and detoxification gene expression.

Contraindications

  • Thyroid conditions (goitrogen at very high doses)

Mechanism

Secondary messenger in insulin signaling cascade. Myo-inositol improves insulin sensitivity, reduces anxiety (via serotonin receptor modulation), and supports ovarian function. D-chiro-inositol complements by activating glycogen synthesis. 40:1 ratio mimics physiological balance.

Contraindications

  • Bipolar disorder (inositol depletion theory — consult psychiatrist)
