Contains precursors to messengers important for the cardiovascular system, exercise, energy production, antioxidant protection and catecholamine synthesis*

Key ingredients
L-citrulline: Precursor to nitric oxide, an important messenger of the cardiovascular system(5-7). Nitric oxide plays a key role in maintaining vascular tone(8), important for exercise(9) and sexual performance(10).

L-tyrosine: Precursor to catecholamines: dopamine, norepinephrine and epinephrine.

Acetyl-L-carnitine: L-carnitine facilitates energy production in mitochondria(11) and provides antioxidant protection through its ability to scavenge reactive oxygen species and metal ions(12).

N-acetyl-L-cysteine: Precursor to L-cysteine that maintains glutathione levels in the body(13).

Mucuna cochinchinensis (standardized to 99% L-DOPA): Natural source of L-DOPA, a precursor to dopamine, norepinephrine and epinephrine(14).
