Vitamin C is an essential water-soluble vitamin with many important functions in the body. Vitamin C (ascorbic acid) is an important cofactor for the production and stability of collagen. The stability and strength of connective tissue, blood vessels, etc. depend upon vitamin C. The body's ability to manufacture neurotransmitters as well as L-carnitine (required for fat metabolism) depends upon optimal intake of vitamin C. In addition to its role in manufacturing important biological compounds, vitamin C is a powerful antioxidant and helps support normal, healthy immune function. Rose hips, in addition to being an excellent source of vitamin C, contain a wide range of beneficial phytochemicals including polyphenols such as anthocyanins as well as beta-carotene, lycopene and lutein. These biologically-active compounds provide a synergistic affect, helping to provide structural and functional support to major body systems.
