Berberine 90 Caps by Starlabs Nutrition is a dietary supplement containing 97% Berberine HCl extracted from the bark of Berberis Aristata, along with Oregon Grape (Mahonia Aquifolium). Berberine is an alkaloid used in Chinese and Ayurvedic medicine for its health benefits. This product works by activating the AMPK pathway, inhibiting mTOR, and mimicking the effects of caloric restriction. This promotes the beta-oxidation of fatty acids, decreases body fat percentage, inhibits hepatic synthesis of triglycerides and LDL cholesterol, and improves insulin sensitivity. It comes in a package with 90 capsules, with a recommended intake of one capsule daily with water, preferably during meals. Do not exceed the recommended daily dose and keep out of reach of children.
