What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and citrus bioflavonoids are supported by strong evidence for antioxidant properties and immune system support. Calcium provides essential mineral support for bone health, while rutin and acerola contribute additional flavonoids. Overall, these ingredients are well-researched, though the specific synergistic effects of this complex have limited clinical documentation.

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. Vitamin C is needed for amino acid metabolism, neurotransmitter synthesis, and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors. This product supplies calcium ascorbate, a buffered form of vitamin C that is bioavailable and non-acidic; it is enhanced with bioflavonoids, which work synergistically with vitamin C.
