🧪 Formulation Notes

Highly soluble

NutriBiotic Calcium Ascorbate is a fully reacted, buffered crystalline powder combining 100% pharmaceutical grade vitamin C (L-ascorbic) and calcium in a highly soluble form.

Vitamin C and calcium 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. Calcium helps maintain bone density. The combined positive effects of vitamin C and calcium make it vital to the body's overall health. NutriBiotic Calcium Ascorbate is manufactured by dissolving ascorbic acid in a solution with calcium carbonate (mined from the earth) creating a fully reacted compound. NutriBiotic Calcium Ascorbate is ideal for individuals looking for an alkaline (buffered) form of vitamin C.
