Tongkat Ali and Testosterone (Everything You Need to Know)

According to the National Institutes of Health, Tongkat Ali, derived from Eurycoma longifolia jack roots, is a Southeast Asian herbal remedy for infections, fevers, and infertility [1].

A report from Researchgate explains that there are three species of plants commonly referred to as Tongkat Ali: Entomophthora apiculata, Goniothalamus, and Polyalthia bullata [2].

Tongkat Ali Eurycoma longifolia’s health advantages most likely derive from the plant's components.

In particular, it includes alkaloids, flavonoids, and other antioxidants.

Antioxidants protect cells from cellular damage produced by molecules known as free radicals [3].

Eurycoma longifolia root extract is usually consumed as tablets or as a herbal drink.

Tongkat Ali boosts testosterone levels by up to 37%, normalizing it in over 90% of users [4].

Eurycoma longifolia extract improves sperm quality, tackling infertility from low testosterone, notably in late-onset hypogonadism [5].

The National Library of Medicine notes low testosterone can stem from aging, certain treatments like chemotherapy, medications, testicular issues, alcoholism, and sleep apnea [6].

Symptoms include low sex drive, erectile dysfunction, and sometimes infertility. Tongkat's chemicals, known to raise testosterone, may combat these issues [7].

Studies show Eurycoma longifolia jack in middle-aged male rats and humans boosts libido and erectile function [8], [9].

A study found from Researchgate with 108 men aged 30–55 taking 300 mg of the extract for 12 weeks saw sperm volume and motility increase by 18% and 44% [10]. These findings suggest it effectively tackles low testosterone and fertility issues in some men, but more research is needed.

Yes, Tongkat Ali has been clinically tested to boost testosterone naturally and has been shown to increase this hormone to normal levels in the body.

Several studies support the notion that Tongkat Ali extract increases free testosterone, total testosterone, dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA) [11].

"Tongkat Ali, like testosterone replacement therapy, may increase testosterone by boosting DHEA levels, and it also acts as an adaptogen, assisting the body in dealing with moderate stress hormones and lowering cortisol. Most studies appear to suggest a good influence on libido as well."

Between 2000 and 2021, studies showed free testosterone increases from 15% to 600% in both genders, depending on dosage and duration.

A 24-week study on 50 mg Physta Tongkat Ali with multivitamins reported up to 582% and 600% increases in male and female free testosterone, respectively [12].

Tongkat Ali contains eurycomanone, which activates the pituitary and adrenal glands, enhancing free testosterone production via sex hormone-binding globulin (SHBG). A 2021 study confirmed Eurycoma longifolia jack's steroidogenic effects in young males, likely due to stimulated hormone production in the hypothalamic-pituitary-adrenal axis [13].

Another well-known effect is its capacity to boost sexual desire, sexual performance, and erectile firmness and regulate reproductive hormones.

In addition to that, it has also been demonstrated to improve male sperm viability and fertility.

"Tongkat Ali extract can boost spermatogenesis and may function as a pro-erectile drug. At least one compound of Eurycoma longifolia (9-hydroxycanthin-6-one) has been linked to both ejaculation delay and pro-erectile characteristics."

One randomized clinical trial looked at the impact of Eurycoma longifolia (Tongkat Ali) on the erectile role and whether it can increase testosterone levels in aged males with androgen deficiency.

It was discovered that males who combined concurrent training with Eurycoma longifolia improved their sexual well-being [17].

Reduced Stress

One research on Sports Nutrition looked at stress hormones in 63 participants who took Tongkat Ali extract or just a placebo for four weeks.

According to the study, the extract significantly reduced people's anger, stress, and uncertainty.

The stress hormone cortisol dropped while testosterone levels surged.

They concluded that Tongkat Ali might be a promising treatment for modern psychological stress, sleep disturbance, and exercise regimen [18].

Athletes occasionally use ergogenic aids to improve their performance.

Based on one 2016 review, Eurycoma longifolia may work as an ergogenic aid since it relieves anxiety and boosts levels of testosterone.

The researchers found that Eurycoma longifolia may have some effect on endurance activities with high doses and long-term intake [19].

Who Should Consider Taking Tongkat Ali?

People who experience problems with low testosterone, low libido, or infertility should consider taking Tongkat Ali (Eurycoma longifolia jack).

According to some studies, it may also lower anxiety and enhance body composition.

While the product appears to be safe at dosages up to 400 mg daily, research is minimal, and published studies concentrate on short-term usage.

Therefore, it is unknown if using the supplements for prolonged periods is effective or safe.

If you’re thinking about taking this product, talk to your doctor first to ensure it's safe for you.

Tongkat Ali is typically taken in 200-400 mg daily doses. Caution is advised, particularly for the elderly and those with weak immune systems, hypoglycemia, or blood pressure issues.

Pregnant or nursing women, children, and individuals with hormone-sensitive cancers or heart or kidney diseases should avoid it.

Excessive use can cause insomnia, restlessness, and increased heart rate [20]. It's essential to adhere to the recommended dosage and consult a healthcare professional before use, especially if you have pre-existing conditions or are on medication.
