Switched On Vitality

Sometimes, it's just not happening.

You feel like you're doing everything right. You're getting to the gym; you're doing your workouts. You're trying to eat clean, taking your supplements, getting enough protein. You're getting your rest.

But the results aren't there. In fact, you could be getting a little softer. You're not bouncing back from workouts the way you once did. You go to bed tired, and wake up tired. So you vow to shake things up and restore your old vitality.

But maybe your malaise springs from something deeper, more hormonal in nature. And your answer might lie in a hardy legume of the tropics.

Growth Hormone and Overall Wellness
Human growth hormone is exactly what it sounds like: it's a peptide hormone that facilitates growth, cell reproduction, and cell regeneration in humans. You produce plenty of it until you're about thirty, when production of human growth hormone (or HGH) begins to decline. By the time you reach age 40, your production of HGH is roughly half of what it was at 20. The decline of HGH has been associated with many less-than-beneficial health outcomes, including everything from increased body fat to loss of energy and bone density. It should come as no surprise, then, that researchers have devoted a lot of time and effort to seeking out supplemental means for supporting HGH production. One such avenue of investigation involves an extract of the velvet bean.

Mucuna Pruriens and Growth Hormone
Mucuna pruriens is a legume native to tropical regions with a long history of use in Ayurvedic medicinal practices. One of its most noteworthy benefits is the support of growth hormone (GH) release.  When administered to trained males, Mucuna pruriens has been linked to support of circulating levels of GH at rest.(1) The active agent of Mucuna pruriens comes from the velvet bean seed, rich in non-protein amino acids and L-dopa (L-3,4-dihydroxyphenylalanine). L-dopa has been examined in research for its GH-supporting properties via facilitation of growth hormone releasing hormone (GHRH).(2) L-dopa, in combination with exercise, has shown to stimulate GH secretion to a greater extent than other GH-releasing triggers (i.e. arginine infusion).(3 )Mucuna pruriens provides a highly bioavailable source of L-dopa.(4)

Essential for the growth of children and adolescents, GH is just as important in adulthood. A 191 amino acid protein secreted by the anterior pituitary gland, GH is vital to anabolism of tissue growth, maintenance and regeneration. This translates to the accrual and preservation of lean body mass. Supporting GH levels may be associated with a number of benefits (i.e. increased protein synthesis [enhanced cellular amino acid uptake], stimulation of lipolysis [break down of fat for energy], stimulation of cartilage growth, collagen synthesis, glycogen sparing, enhanced immune cell function).(5) GH also elicits the release of IGF-1, which contributes to protein anabolism, working synergistically to increase muscular hypertrophy.(6)

Stressed and fasted states induce catabolism, threatening the integrity of muscle mass.  With adequate circulating GH, however, free fatty acids are used for energy along with induced lipolysis, sparing glucose and protein oxidation. Thus, GH may protect muscle mass during catabolic states.(7)  GH is also imperative in other physiologic states where muscle protein breakdown is evident. GH is sensitive to mechanical overload. The stress of resistance training requires GH for hypertrophic adaptation to moderate-to-high-intensity lifting protocols that incorporate higher volume and shorter rest periods.(8-10)  Furthermore, exercise protocols that elicit elevations in lactic acid are associated with GH release.(11)

Aging is correlated with an inevitable decrease in IGF-1 and GH, threatening the integrity of physical strength, muscle, and bone.(12,13) Supporting GH and IGF-1, and preventing their age-related decline, may combat these unpleasant side effects (i.e. loss of muscle mass, decreased bone mineral density). Furthermore, protecting GH levels may prevent negative effects on body composition, cognitive function, skin integrity (i.e. wrinkles), self-perception, energy, strength, sleep quality and libido.(14-16) Studies have shown that GH restoration and promotion may have favorable effects on body composition (increasing muscle mass while decreasing body fat), exercise performance, and overall quality of life.(17,18)

Mucuna Pruriens, Antioxidant Defense and Virility
Shukla et al.(19) observed notable antioxidant activity with Mucuna pruriens administration, promoting replenishment of glutathione while decreasing markers of oxidative stress. Research suggests its antioxidant boosting effects may increase sperm production and motility.(20) Mucuna pruriens supplementation also resulted in modulated psychological stress reduction. In addition to optimizing antioxidant status, Mucuna pruriens has also been associated with support of testosterone and dopamine levels among test subjects.(21)  Mucuna pruriens has also been linked to possible libido-boosting properties.(22)
