Side-by-side comparison of mechanisms, dosing, interactions, and stacking potential.

Inositol (Myo-Inositol + D-Chiro-Inositol)PQQ
CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelStrong (PCOS, anxiety), Moderate (general metabolic)Moderate

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)
B

PQQ

Supplements

Mechanism

Redox-active quinone that supports mitochondrial biogenesis signaling and resilience under oxidative load.

Contraindications

  • Limited long-term human safety data
