Formulation Notes

Highly soluble

NutriBiotic Meta-C powder is a unique, buffered vitamin C with biologically active metabolites from spirulina, a single-celled, blue-green algae rich in nutrients.

Meta-C powder absorbs fast and efficiently, rapidly dissolves, and is highly soluble.

Meta-C is produced by water-processing vitamin C and calcium with an array of biologically active metabolites at low temperatures. This creates a fully reacted calcium ascorbate, which is then combined with spirulina to form an advance food-bound nutrient system providing all the properties found in concentrated whole foods such as protein, lipids, glycoproteins, lipoproteins, nucleoproteins (RNA/DNA), complex carbohydrates, phytopigments, flavonoids, fatty acids, enzymes, co-enzymes, trace elements, and fiber. Vitamin C and calcium are essential nutrients that provide 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 combined positive effects of vitamin C, calcium, and spirulina make Meta-C powder an excellent choice for supporting the body's overall health.
