What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and citrus bioflavonoids are supported by strong evidence for their roles in antioxidant protection and immune function. Calcium is well-documented for maintaining bone density and neuromuscular health. Rose hips and acerola powder provide additional botanical sources of ascorbic acid, though specific clinical evidence for these powders is more limited.

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 hat can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors.

This product utilizes calcium ascorbate, a buffered form of vitamin C that is bioavailable and non-acidic, and is enhanced with bioflavonoids, which work synergistically to support Vitamin C utilization.
