Formulation Notes

Rapid Dissolving

NutriBiotic Buffered Vitamin C capsules deliver 100% pharmaceutical grade vitamin C (L-ascorbic acid) in combination with an array of highly bioavailable minerals, including calcium, magnesium, potassium, and zinc (which are mined from the earth), to form mineral ascorbates. Ascorbates are buffered and, therefore, less acidic than pure vitamin C. Vitamin C, calcium, magnesium, potassium, and zinc are essential nutrients that help support the body. Vitamin C provides antioxidant protection to the immune system, as well as maintains the health of blood vessels, tissue, cartilage, bones, eyes, and other organ systems. Vitamin C is also required for the biosynthesis of collagen, L-carnitine, and neurotransmitters. The other nutrients in Buffered Vitamin C help maintain bone and immune health and regulate fluid balance, muscle contractions, and nerve signals. The positive effects of the combined nutrients make them vital to the body's overall health. These capsules provide vitamin C and minerals in a pure, pre-measured form. These potent, water-soluble nutrients are encapsulated to be convenient, easy-to-swallow, and rapidly dissolving.
