Formulation Notes

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 and the utilization of many nutrients such as folic acid and iron. It is also a highly effective antioxidant that can help maintain healthy tissue by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors.
