After suffering with constipation on and off for many years, (despite a healthy diet), I decided to try this product after reading about it on Dr Andrew Weil website. It works very well, no cramps & actually alleviated the gas and bloating I was experiencing as well. I started out by taking 1 capsule every night before bed. After my morning coffee, I was able to move my bowels (I think it took 3 or 4 days to work). It worked this way for about a month & then I seemed to build a tolerance, so I started taking the recommended 2 capsules every night. I will been doing this for almost 3 months and it works without fail! This is an amazing product and has been a miracle for me. If you suffer from constipation or IBS with constipation, do not hesitate to try this product.
