Solgar Vitamin C 1000mg with Rose Hips is a top quality product, containing high strength Vitamin C plus Rose Hips which are a natural, rich source of Vitamin C. Vitamin C is an antioxidant vitamin essential to the body's health and is especially important for maintaining healthy skin. Vitamin C is a water-soluble vitamin, sourced from natural ingredients such as rose hips and acerola. Rose hips contain bioflavonoids which naturally occur with vitamin C in nature. Bioflavonoids help to enhance the absorption and bioavailability to make sure you will receive all the benefits from Vitamin C. Humans cannot make their own Vitamin C so daily replenishment is essential. Its primary function is to maintain collagen, a protein necessary for the formation of skin, ligaments, bones and teeth, and for the strength of blood vessel walls. In addition, Vitamin C plays an important part in the absorption of iron, which is necessary for the formation of red blood cells. It also plays a role in the utilisation of folic acid.
