Translations:Biotin/13/en

The large intestine microbiota synthesize amounts of biotin estimated to be similar to the amount taken in the diet, and a significant portion of this biotin exists in the free (protein-unbound) form and, thus, is available for absorption. How much is absorbed in humans is unknown, although a review did report that human epithelial cells of the colon in vitro demonstrated an ability to uptake biotin.
