Subclinical deficiency can cause mild symptoms, such as hair thinning, brittle fingernails, or skin rash, typically on the face. SMVT also binds pantothenic acid, so high intakes of either of these vitamins can interfere with the transport of the other. The large intestine microbiota synthesizes 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.
