You should be able to get all the pantothenic acid you need from your daily diet, as it’s found in many foods. There’s not enough evidence to know what the effects might be of taking high daily doses of nicotinamide supplements. Taking high doses of nicotinic acid supplements can cause skin flushes.
For profound deficiency, treatment is oral dosing with 5 to 20 mg per day. It is also important in freeing biotin from dietary protein-bound biotin. Urinary excretion of this compound is an early and sensitive indicator of biotin deficiency. 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.
