✨ AI-generated · Qwen 3.6 · methodology

L-arginine, L-citrulline, and L-ornithine are amino acids researched for their role in nitric oxide production and blood flow. Evidence for these ingredients in enhancing athletic performance is generally moderate to limited. Vitamin B6 supports protein metabolism, though the overall evidence coverage for this specific combination is low.
