What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and lemon bioflavonoids are supported by strong evidence for antioxidant and immune system support. Spirulina provides nutritional support, though research on its specific clinical efficacy is more limited. The combination of metabolites and dehydroascorbic acid aims to enhance bioavailability.

Formulation Notes

Rapid Dissolving

NutriBiotic Meta-C is a unique, buffered vitamin C with biologically active metabolites from spirulina, a single-celled, blue-green algae rich in nutrients. Meta-C Capsules absorb fast and efficiently and contain the added benefits of bioflavonoids from lemons. Meta-C is produced by water-processing vitamin C and calcium with an array of biologically active metabolites at low temperatures. This created a fully reacted calcium ascorbate, which is then combined with spirulina to form an advanced 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 maintain 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, spirulina, and bioflavonoids make Meta-C Capsules an excellent choice for supporting the body's overall health.
