Prebiotic Fiber. Enriches and Bourishes the Gut Microbiome. With Beneo. Vegan. Inulin and FructoOligoSaccharides (FOS) are soluble 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 growth of unfriendly bacteria, reduce the absorption of toxic ammonia and positively affect bone health byincreasing the bioavailability of dietary calcium. Moreover, acetate, propionate and butyrate promote the integrity of the intestinal cells lining the colon and promote healthy lipid metabolism. OraftiSynergy1 delivers both long-chain and short-chain saccharides to the gut, optimizing the growth of beneficial bacteria.
