A healthy colon is vital to the efficiency of a healthy digestive system. It absorbs water and excretes waste materials from the body. Over five feet in length, the colon requires a lot of energy to function properly. Around 70% of that energy is supplied by a short-chain fatty acid known as butyric acid. Low levels of butyric acid may result in conditions such as irritable bowel syndrome and abdominal pain. Allergy Research Group ButyrEn 100 Delayed-Release Vegetarian Capsules have been developed to nourish the cells in the colon and maintain the levels of healthy Bifidobacterium in the large intestine.

Each of the Allergy Research Group ButyrEn 100 Delayed-Release Vegetarian Capsules is 100% vegetarian and coated in an enteric shell to ensure slow, consistent release. They contain a blend of magnesium salts and butyric acid to ensure colon health. However, this product is unsuitable for pregnant women or those trying to conceive, as it contains chemicals that have been known to cause reproductive harm and birth defects. For the best results, take one or two tablets, three times per day, with meals.
