What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin C and citrus flavonoids provide antioxidant support, while L-lysine is associated with immune function. Research for these components is generally strong, though evidence for calcium alpha-ketoglutarate is more limited. Together, these ingredients target cellular health and immune system maintenance.
