1. Male Reproductive Health
In men, testosterone levels peak between the ages of 25 and 30 before dropping by about 1% each year. By these metrics, testosterone levels will be roughly half of youthful levels by the age of 60. This problem is made worse by other factors such as stress, poor diet, and lack of exercise.
Longjack has become a popular supplement by men of all ages to optimise their testosterone levels, and combat the natural degradation and loss of androgen levels that come naturally with age.
The root bark of Longjack contains a series of peptides known as eurypeptides — which have been shown to provide improvements in energy levels and sexual function in animal studies. Scientists believe the primary mechanism used by this herb to support this is through its effects on male androgens — such as testosterone and various other growth hormones.
Longjack is thought to improve testosterone levels by activating an enzyme in the liver known as CYP17 — which is responsible for converting pregnenolone and progesterone into dehydroepiandrosterone (DHEA).
DHEA is one of the most abundant androgens in the human body, which then goes on to support the production of testosterone.
2. Athletic Performance
Many of the effects of Longjack listed above also apply to its role as an athletic performance enhancer.
Testosterone, and other anabolic steroids produced in the human body play a major role in the production and maintenance of muscle and bone tissue throughout the body.
As testosterone levels decline with age, so does muscle mass and bone density — two factors that can severely reduce our athletic ability.
By supporting optimal testosterone levels as we age, Longjack is thought to maintain a youthful level of athletic performance well into old age. Although the effects of Longjack in this respect aren’t immediate, over long periods of time this herb may be used to delay the natural decline of athletic performance as testosterone levels drop year by year.
