Prebiotic Soluble Fiber FructoOligoSaccharides Promotes Probiotic Bacteria Growth With Beneo Dietary Supplement Non GMO Suitable for Vegetarians/Vegans Inulin and FructoOligoSaccharides (FOS) are soluble prebiotic fibers that promote gut and overall health through their fermentation by gut flora to yield important metabolites, including lactic acid and the short chain fatty acids acetate, propionate and butyrate. These metabolites help to maintain proper pH in the gut, discourage the growth of unfriendly bacteria and increase the solubility of dietary calcium. Moreover, acetate, propionate and butyrate promote the integrity of the intestinal cells lining the colon and may promote healthy lipid metabolism. Orafti Synergy1 delivers both long-chain and short-chain saccharides to the gut, optimizing the growth of beneficial bacteria.
