I am a new customer to colosan powder and find it absolutley brilliant. I have been diagnosed with a lazy bowel and IBS for the past 26years and spent £1's on prescription drugs and medicines and nothing seemed to help ease my problem. Aproxiamatley i have spent 4 months per year in agony, I cant describe the pain i have been in ? I contacted Mark and he advised colosan, I must say of all the things i have tried this product is FANTASTIC !!! I am starting to feel that i now have something to live for now and enjoy life more Big thankyou to Mark
