I've been using Posture-D but now I can't buy it over the counter. I can't find it anywhere and I need help finding this item. ## I'm sorry, but we have no way of knowing what store, or pharmacy has anything in stock, at any given time. Have you tried searching online to see if you can order it anywhere? Posture-D is just a calcium supplement, so if you can't find it, you may be able just to ask your pharmacist to help you pick an equivalent supplement.
