L-DOPA is a natural amino acid obtained from the seeds of Mucuna pruriens (a.k.a. velvet bean). In the nervous system L-DOPA acts as a direct precursor of two important neurotransmitters: dopamine and noradrenaline. When supplemented, it helps to increase the level of motivation, prolongs the span of attention and promotes psychological wellness. Moreover, by supporting hormonal balance, it improves sexual performance.
