Cranberry Plus HL contains cranberry extract with added Proanthocyanidins (also known as PACs, the main active ingredient in Cranberry fruit), vitamin C, and zinc. The ingredients of the preparation help maintain the urinary tract in good condition and health. Cranberry is rich in vitamin C, polyphenols, and minerals. It also contains a large amount of oligomeric proanthocyanidin (OPC), which, among other things, inhibit the adhesion of bacteria to the wall of the ureters and the bladder. In this way, it can inhibit the colonization of the urinary tract by bacteria. Polyphenols inhibit the formation of free radicals, which protects cells from damage under oxidative stress and reduces inflammatory processes. Vitamin C and zinc also help to protect cells against oxidative stress and the proper functioning of the immune system. Additionally, vitamin C and zinc are involved in the regulation of metabolism. Vitamin C contributes to the maintenance of normal energy metabolism, and zinc helps to maintain the proper metabolism of carbohydrates, fatty acids, and DNA.
