Inositol (Myo-Inositol + D-Chiro-Inositol)Sulforaphane (from Broccoli Sprout Extract)
CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelStrong (PCOS, anxiety), Moderate (general metabolic)Strong

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)

Mechanism

Isothiocyanate that activates Nrf2 — the master regulator of antioxidant defense. Upregulates glutathione synthesis, phase II detoxification enzymes, and heat shock proteins. Also inhibits HDAC (epigenetic modifier) and NF-kB (anti-inflammatory).

Contraindications

  • Thyroid conditions (goitrogen at very high doses)
  • Cruciferous vegetable allergy
