I have tried various forms of digestive enzymes - some have minimal results, some require taking 2 or more capsules - I still did not feel my food was properly digested. Without effective digestion, I would not be able to assimilate sufficient nutrients for my health. When I came across "Integrative Digestive Formula" 4 years ago, I was impressed with The Asian Digestive Blend, Traditional Chinese Botanical Digestive Blend and Organically Grown Digestive Mushroom Blend, since then, I have not stop taking just one capsule before each meal and it works very well for me. I will continue taking this product and recommend others to try it.
