"There are many different cofactors that can improve dysglycemia such as zinc, alpha lipoic acid, chromium, and vanadium. According to a study published earlier this month, researchers demonstrated that Ginkgo biloba extract can significantly reduce HA1c, fasting glucose, insulin, BMI, and waist circumference.This study included 60 patients ranging from 25 to 65 years of age with type 2 diabetes who had a glycemic status uncontrolled by metformin alone. These individuals were randomized to treatment of 120 mg/d of ginkgo extract or placebo for 90 days. Biomarkers were assessed at baseline and at 90 days, including HA1c, fasting glucose, insulin, waist circumference, and visceral adiposity index (VAI).As a result, the ginkgo extract significantly reduce HA1c, fasting glucose, insulin, and waist circumference. Treatment with ginkgo combined with metformin decreased BMI significantly after 90 days.
