I can feel a small difference in the past few days I have been taking them, starting to see a different in the eat habits now. I love this brand because the put more of the stuff you need in them, like Calcium and Potassium, that keeps the leg cramps away. It does a take days to feel the full effects of this product. You will notice that you don't eat as much sweets at first off. I received this at a very heavy discount for a honest review.
