How can I increase biotin absorption? To maximize the intake of biotin and for safety reasons, always cook eggs before eating them. Raw egg white contains a protein called dietary avidin, which binds to biotin and makes it harder for the body to absorb it. Cooking separates the biotin from the avidin, helping the digestive tract to absorb the vitamin.
What inhibits the absorption of biotin? Dietary avidin, a glycoprotein in raw egg whites, binds tightly to dietary biotin and prevents biotin’s absorption in the gastrointestinal tract [13,14].
Is biotin easily absorbed? Most biotin in food is protein bound and must be released prior to intestinal absorption. Biotin is water soluble and as a result free biotin is absorbed almost 100%. Almost 50% of ingested biotin is excreted unchanged in urine. Biotin has no known toxicity.
How does biotin get absorbed?
How Does Absorption Work? Biotin in food is bound to proteins. Then, these proteins get broken down by enzymes found in the pancreas and the small intestine, freeing the biotin. The biotin is then absorbed by the small intestine.
