Velvet bean (Mucuna pruriens) is used to support the pituitary body system primarily due to its high content of L-DOPA, a direct precursor to dopamine. Dopamine acts as a major neurotransmitter and also regulates the secretion of several hormones by the pituitary gland, particularly prolactin and growth hormone. There is scientific evidence suggesting that Mucuna pruriens supplementation can increase circulating dopamine levels and modulate pituitary hormone release. Clinical studies have shown that Mucuna pruriens can elevate growth hormone levels in both animals and humans, likely through dopaminergic mechanisms. Furthermore, increased dopamine from L-DOPA has been shown to inhibit prolactin secretion, which is directly relevant to pituitary function. However, most of the clinical research focuses on neurological disorders (such as Parkinson’s disease), and only a limited number of studies directly examine pituitary hormone modulation in healthy individuals. The traditional use of velvet bean is more commonly linked to male fertility and neurological health than to explicit pituitary support. Nevertheless, the physiological pathway—L-DOPA conversion to dopamine affecting pituitary hormone regulation—is well-established. Therefore, use of velvet bean to support pituitary function has a plausible scientific foundation, though large-scale clinical trials specifically measuring pituitary outcomes in healthy populations are relatively limited.
