Maxentra names its active ingredients. Here is what each is and what human research generally shows. These are descriptions of the ingredients themselves — Maxentra lists only a 30 mg total for all three, with no individual amounts.
An amino acid the body uses to make nitric oxide. Studies often use several grams a day. Results for blood flow and exercise are mixed, it may upset the stomach, and it can lower blood pressure.
Arginine bound to alpha-ketoglutarate, a compound sold in sports products. Evidence for better performance or muscle outcomes is limited and inconsistent.
Citrulline is converted into arginine in the body and may raise arginine levels more reliably than arginine itself. Small studies using roughly 3,000–8,000 mg suggest modest effects on exercise and fatigue. Malate is added for taste and stability.
