This formula leans on ingredients with real research behind blood sugar metabolism: alpha lipoic acid and banaba leaf extract (standardized for corosolic acid) are both studied for supporting healthy glucose metabolism, while bitter melon has a long history of traditional and clinical use for the same purpose. Acetyl-L-carnitine and L-carnitine fumarate are included to support how the body uses fat for energy. This is a support formula, not a substitute for a low-glycemic diet or for medical management of blood sugar, and anyone on diabetes medication should talk to their doctor before adding it, since some of these ingredients can affect blood sugar levels.
