What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C and citrus bioflavonoids are supported by strong evidence for antioxidant activity and immune system support. Acerola and rose hips provide natural sources of ascorbic acid and polyphenols, though specific clinical data for these powders is more limited. Together, these ingredients aim to support collagen synthesis and cellular protection.

Additional Information

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 protect the body's cells and molecules from damage by free radicals and reactive oxygen molecules generated during normal metabolism and exposure to environmental stressors.*
