I have a few questions about the supplement D-Chiro-Inositol. One, where can I buy it? GNC? Or is it a prescription? Two, has anyone here used it and what were the results? It is supposed to make you more insulin sensitive and helps women with PCOS symptoms. My plan is to take Metformin, do low, low carb and use the d-chiro supplement to stabilize my insulin levels/lose a little weight and get pregnant again. I'd love a little advice.
