What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Citrulline malate and caffeine have strong evidence for improving exercise performance and alertness. Acetyl-L-Carnitine and agmatine sulphate may support metabolic function and blood flow, though evidence for these is more limited. French pine bark extract is included for potential vascular support.
