Does the Niacin in the NIA 24™ products affect the Niacin that I am taking in a multi-vitamin or B complex vitamin?
The bioavailability and metabolic pathways are different for vitamins which are applied topically versus those administered orally. Because the NIA 24™ products are topically applied, the absorption of Pro-Niacin™ into the cells is localized primarily to the skin. In addition, there should be no concern about Niacin toxicity because Niacin is water-soluble and doses found in multi-vitamins or in B-complex are typically low.
