Mechanism

Leucine metabolite that reduces muscle protein breakdown and may support recovery under high training or caloric deficit conditions.

Contraindications

  • None established at standard 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)
