Side-by-side supplement facts comparison
C-500, Calcium Ascorbate-C, 100 Veg Capsules
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. This product supplies calcium ascorbate, a buffered form of vitamin C that is bioavailable and non-acidic; it is enhanced with bioflavonoids, which work synergistically with vitamin C.
