Nature's Essentials Cyclo-C™ utilizes our proprietary Cyclosome™ liposomal advanced delivery technology for immune boosting Vitamin C with Bioflavonoids for a more bioavailable and more effective vitamin. This delivery technology preserves the high quality Vitamin C using natural phospholipids and increases solubility that helps it release directly into the cells. Vitamin C is one of the most popular antioxidants known to man and is important for promoting immune system health, but studies show that the benefits of some Vitamin C with bioavailability are more vast than previously thought. This is truly the next generation of Vitamin C.
