I have coeliac disease and have always suffered bloating and constipation even though I stick to a strict diet. These reformulated Oxy-Powder capsules work fine. I take 4-6 capsules every other day. It works much better on an empty stomach so at least 2 Hrs after food just before bedtime and the crucial thing is to drink with 1 pint of water - although I hate water so I put 2 effervescent Vitamin C tablets into the water which makes the water taste nice. This treatment has stopped the bloating and its wonderful to have a flat stomach again and not look like I'm 9 months pregnant - especially as I am a man!! Men have body image issues as well as women and thankfully this has cured mine.
