What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Quercetin and Vitamin C are supported by moderate evidence for their antioxidant and immune-supporting properties. Bromelain and citrus bioflavonoids are often included to enhance absorption and reduce inflammation, though clinical evidence for these specific combinations is more limited. The profile maintains a high safety rating for general use.
