Natural Factors Liposomal Vitamin C - An advanced, highly absorbable source of vitamin C that is easy to digest. Vitamin C is an essential nutrient and well-known antioxidant. It plays important roles in immune system function and collagen formation, making this vitamin critical to wound repair and maintaining healthy bones, cartilage, teeth, and gums. Standard forms of vitamin C can be difficult for the body to absorb, which can limit its effectiveness. Liposomal Vitamin C eliminates this absorption problem by enclosing vitamin C within a protective phospholipid bilayer. This allows vitamin C to remain intact during digestion and ensures rapid, efficient uptake into cells and sustained release over time.
