Supplementation with 200 mg per day of the E. longifolia extract combined with or without a concurrent training program was associated with higher testosterone levels after six months, compared to placebo, in men with Androgen Deficiency of Aging Males (ADAM), a condition that reportedly affects between 6 and 12% of middle-aged men worldwide.
Improvements in a range of other measures, from cardiorespiratory fitness measures such as VO2 peak and heart rate to decreased body fat and waist circumference, to sexual measures like erectile function and sexual desire.
“The interventions carried out in this study are feasible in practice, which is capable of obtaining results that impact the daily lives of men who experience the ADAM process, providing a healthier and more active aging process, and, consequently, a higher quality of life,” wrote scientists from the State University of Santa Catarina in Complementary Therapies in Clinical Practice.
“Asian Viagra”
Eurycoma longifolia (Tongkat Ali) comes from the root of a tree native to Malaysia, Thailand and Indonesia, and was dubbed the “Asian Viagra” by the New Sunday Times in 1999. Supplements containing the ingredient are often positioned for male libido, energy, weight loss, and sports performance.
Annie Eng, CEO of HP Ingredients, which supplies the US market with the branded LJ100 Eurycoma longifolia extract, commented: “These two studies overall validate our previous research on LJ100 in men, which is compelling news for formulators. As more men are proactive about their health and no longer embarrassed to take measures to support their sexual abilities and virility, LJ100 is a powerful tool for this ever-growing audience.”
