Zinc L-carnosine is a complex of the mineral zinc and the dipeptide L-carnosine (consisting of beta-alanine and histidine) and is synthesized to combine the therapeutic properties of both zinc and L-carnosine, aiming to offer a synergistic effect. Zinc L-carnosine is particularly noted for its role in gastrointestinal health, where it has been studied for its potential benefits in protecting and healing the gastric lining, making it a popular supplement for managing conditions like gastritis, ulcers, and other gastrointestinal issues.
