Uses for Tongkat Ali
In alternative medicine, tongkat ali is said to raise testosterone levels, promote muscle strength, and address a number of conditions such as erectile dysfunction, decreased libido, fatigue, and stress.
1) Erectile Dysfunction and Low Libido
Tongkat ali Benefits of Tongkat Aliis often touted as a remedy for erectile dysfunction. There’s some preliminary evidence that it may help. For instance, a small study published in Evidence-Based Complementary and Alternative Medicine, researchers found that twelve weeks supplementation of a product containing a Eurycoma longifolia extract and Polygonum minus (an antioxidant) helped to enhance sexual performance and erectile function.
Another study, also published in Evidence-Based Complementary and Alternative Medicine, suggests that a tongkat ali extract may aid in the treatment of low libido and erectile function.
Involving 109 men between 30 and 55 years of age, the study found that the extract may help increase erectile function, sexual libido, sperm motility, semen volume. Loss of fat mass in those who were overweight was also noted.
2) To Build Muscle
Tongkat ali may increase muscle mass and strength due to its purported effects on testosterone levels.
It is sometimes used as to boost athletic performance, physical strength, and to promote fat loss. In a preliminary study published in the British Journal of Sports Medicine, researchers found that 100 mg/day of a Eurycoma longifolia extract for five weeks increased muscle mass and strength in men participating in an intensive strength training program compared to those who participated in the program alone.
Tongkat ali may also help to increase muscular strength in older adults, according to a pilot study published in Phytotherapy Research in 2014. For the study, 13 men and 12 women between the ages of 57 and 72 took 400mg of a tongkat ali extract daily for five weeks. At the study’s end, tongkat ali was found to have raised free and total testosterone levels and muscular force.
A study involving male recreational athletes, however, found that 150 mg/day for seven days before an endurance run (plus an hour before the run) didn’t increase endurance compared to a placebo.
Tongkat ali shows promise in the treatment of infertility, suggests a preliminary study published in the Asian Journal of Andrology in 2010.
Researchers found that 200 mg/daily supplementation with Eurycoma longifolia in men for three to nine months resulted in higher semen volume, sperm concentrations, percentage of normal sperm morphology, and sperm motility, and resulted in spontaneous pregnancy in 11 of the participants' partners after treatment.
Some research suggests that tongkat ali may help to relieve stress. The available research includes a small study published in the Journal of the International Society of Sports Nutrition. Investigators assessed stress hormones and mood state in 63 people before and after taking a tongkat ali supplement for four weeks and found significant improvements in the mood states of tension, anger, and confusion as well as decreased salivary cortisol and increased testosterone in those taking the tongkat ali extract.
