Vitamin B Intercalated in Layered Double Hydroxides: A Drug Delivery System for Metabolic Regulation.

The organic compound niacin or nicotinic acid, also known as vitamin B (VitB), is essential for human nutrition and metabolic regulation. However, in high doses, it can provoke side effects, such as hyperglycemia, liver damage, and flushing. Development of a controlled release system that slowly releases VitB into the organism would avoid high dosing peaks, thus contributing to decrease the occurrence of side effects in nutritional supplementation.
