Lipoic Acid Supreme is a formula designed to help support healthy blood sugar levels and insulin balance. It combines lipoic acid with the amino acid taurine and biotin -a member of the B vitamin family. Long-term supplementation of lipoic acid may reduce biotin levels because lipoic acid competes for biotin-dependent enzymes. Therefore, it is recommended that they are supplied together. Taurine and biotin also play important roles in fostering healthy insulin function.
