• Vitamin C with Rose Hips and Bioflavonoids Complex

Vitamin C (ascorbic acid) has numerous biological functions. Foremost, it is essential for the synthesis of collagen and glycosaminoglycans which are the building materials of all connective tissues, such as skin, blood vessels, tendons, joint cartilage and bone*.

Vitamin C is the required coenzyme for two groups of enzymes that catalyze the cross-linking of collagen fibers - lysyl hydroxylases and prolyl hydroxylases. As such, vitamin C is essential for normal wound healing and capillary health. Vitamin C also participates in the biosynthesis of carnitine, serotonin, and certain neurotransmitters, including norepinephrine*.

Vitamin C is among the most powerful antioxidants in humans and animals. It is a water-soluble, chain-breaking antioxidant that reacts directly with superoxide, hydroxyl radicals, and singlet oxygen*. The antioxidant functions of vitamin C appear to have clinical significance in providing support for free radical damage protection to the eyes, lungs, blood and the immune system*.

Bioflavonoids (also called flavonoids) are a class of phytochemicals that are potent antioxidants, which provide support for scavenging many potentially damaging free radicals*. Another aspect of the antioxidant properties of bioflavonoids is their synergy with vitamin C, as well as their ability to bind to metal ions, preventing these metals from catalyzing enhanced free radical production*.

Many bioflavonoids support the health of the bodys circulatory system by helping maintain capillary blood flow and proper vascular permeability, integrity, and resiliency.*
