Basis: Stereoisomer of myo-inositol with the same formula (C6H12O6), so declared weight equals inositol weight (mass factor 1.0)

Why this tier: A distinct stereoisomer, not a different delivery form of myo-inositol; it appears in PCOS products usually alongside myo-inositol. In an 18-volunteer crossover, adding 1,000mg D-chiro-inositol to 6,000mg myo-inositol reduced myo-inositol Cmax (1.29-fold) and AUC (19%).
