Corosolic Acid is a food-grade pentacyclic triterpene extracted from banaba leaf (Lagerstroemia speciosa) and other plants.We supply bulk Corosolic Acid sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Corosolic Acid is widely used in diabetic-support supplements, fat-loss formulas, metabolic-health nutraceuticals, insulin-sensitivity products and recovery.
Corosolic Acid is isolated from banaba leaf or other plant sources by ethanol extraction, purification and crystallisation.
This yields white crystalline powder at 1–98% purity. Known as 'plant insulin', it enhances glucose uptake into cells, improves insulin sensitivity, and supports glycaemic balance, widely used in diabetic-support and weight-management supplements.
