Scientific Studies About How Tongkat Ali Increases Testosterone

Professor Mohd Ismail Bin Mohd Tambi conducted a study in Malaysia on the standardized water-soluble extract of Eurycoma longifolia, commonly known as Tongkat Ali.

The study observed significant changes in AMS (The Ageing Males’ Symptoms) scores and testosterone levels before and after the treatment.

Notably, the AMS score decreased from 38.05 ± 9.25 to 23.67 ± 5.11, while the testosterone concentration increased from 5.66 ± 1.52 to 8.31 ± 2.47 nm, indicating an average increase of 46.8% [1].

Another scientific study [2] conducted to investigate the effects of Tongkat Ali on testosterone levels and erectile function in men with ADAM (androgen deficiency of aging males) yielded significant findings.

Employing a double-blind methodology, the study concluded that the combination of Eurycoma longifolia not only improved erectile function but also elevated total testosterone levels in men with ADAM.

Additionally, the study emphasized that older men who combined Tongkat Ali supplementation with regular exercise demonstrated superior results compared to the other groups involved in the trial.

Apart from the studies above, when searching for "Does Tongkat Ali increase testosterone?" you will find many studies that strongly support its effects.

How Does Tongkat Ali Increase Testosterone?

mechanism of tongkat ali to increase testosterone

The answer to this question lies in the active compounds found in Tongkat Ali.

These biologically active phytochemicals, such as eurycomanone and eurycomanols, work by stimulating the production of luteinizing hormone, which in turn induces testosterone production [3].

These compounds have also been found to counteract the SHBG (sex-hormone binding globulin) and limit its effect on inhibiting free testosterone.

The combination of these two processes results in an increase in total, as well as free, testosterone levels [3].

Thus, Tongkat Ali is able to modulate and optimize hormonal balance for enhanced performance and improved quality of life.

How Much Does Tongkat Ali Increase Testosterone?

Most of the research studies suggest an average percentage increase ranging from 20 to 40%, even higher, up to 46.8% [1]. If users combine Tongkat Ali with regular exercise, Tongkat Ali's effects may be stronger [2].

However, it is worth noting that due to individual differences in body composition, metabolic rate, lifestyle choices, and genetics, the exact amount of testosterone can increase can vary from person to person.

Even many opinions suggest that Tongkat Ali may help increase natural testosterone, but only at a low and insignificant level.

Therefore, to get the best results, it is recommended that you take a quality Tongkat Ali supplement and maintain a healthy lifestyle, which includes regular exercise and a balanced diet.
