C-500 with Rose Hips, 250 Tablets
Vitamin C is a water soluble nutrient well known for its vital role in the immune system. Vitamin C is also necessary for the production of collagen (a structural protein in connective tissue) and is therefore important for skin, bone, and joint health. Vitamin C is needed for amino acid metabolism, neurotransmitter synthesis, and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors. Rose hips, which are natural sources of ascorbic acid, have been included to complement this formula.
