🧪 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. It is also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals. This product includes bioflavonoids, which work syngergistically to support vitamin C utilization.

Natural color variation may occur in this product.
