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].
How is biotin 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.
Why is my body not absorbing biotin? Taking antibiotics over a long period, as these can destroy the biotin-producing bacteria in the gut. Having a condition, such as Crohn’s disease, that makes it hard for the gut to absorb nutrients. Having excessive exposure to alcohol, which inhibits biotin absorption.

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.
Can biotin be absorbed through the scalp?
Biotin contributes to healthy nails, skin and hair, so it features in many cosmetic and health products for the skin and hair. However, it cannot be absorbed through hair or skin.

As a water-soluble nutrient, vitamin B7 is absorbed rapidly. When you are deficient in this substance, you absorb it more slowly, but in healthy adults, approximately 90% of ingested biotin is absorbed within 24 hours.
What are the symptoms of low biotin?
Side effects of biotin deficiency
What causes low biotin?
Consuming raw eggs on a regular basis for an extended time causes biotin deficiency because avidin present in egg white tightly binds biotin thus making biotin unavailable for intestinal absorption. Cooking eggs denatures avidin, thus impairing its ability to tightly bind biotin.
Is 10000 mcg biotin too much?
Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date. Reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.
