B Vitamin Supply
B vitamins (including biotin, folate, B5, B6, and B12) are water-soluble, meaning the body does not store them and they must be replenished through food regularly. GLP-1 medications significantly reduce how much most people eat. As a result, daily B vitamin intake may decrease alongside overall calorie intake. Hair follicles are among the fastest-growing cells in the body and depend on adequate B vitamin availability.
