Tongkat Ali And SHBG

Tongkat Ali And SHBG

Tongkat Ali, scientifically known as Eurycoma longifolia, is a traditional herbal remedy that has gained popularity for its potential aphrodisiac and testosterone-enhancing properties.

One of the mechanisms through which Tongkat Ali may impact male hormonal balance is by influencing the levels of Sex Hormone Binding Globulin (SHBG).

Understanding Sex Hormone Binding Globulin (SHBG)

Sex Hormone Binding Globulin (SHBG) is a protein synthesized by the liver that binds to three main sex hormones: testosterone, dihydrotestosterone (DHT), and estradiol (a form of estrogen).

SHBG acts as a transport protein, regulating the availability and bioactivity of these hormones in the body. When bound to SHBG, hormones become less active, as they are less readily available to exert their effects on target tissues.

Tongkat Ali and SHBG

Research suggests that Tongkat Ali may influence SHBG levels and consequently impact hormonal balance. Several studies have investigated the effects of Tongkat Ali extract on SHBG in both animal and human models, yielding interesting findings.

  1. Reduction in SHBG levels: Studies have shown that Tongkat Ali supplementation may lead to a decrease in SHBG levels. This reduction can potentially result in increased free testosterone, which refers to the testosterone that is not bound to SHBG and is available for use by the body. Elevated levels of free testosterone have been associated with improved libido, muscle growth, and overall sexual well-being.

  2. Regulation of estrogen: Tongkat Ali's impact on SHBG levels may also influence estrogen balance in the body. As SHBG binds to estradiol, a decrease in SHBG could potentially lead to increased levels of free estradiol. While more research is needed to fully understand the implications of this, it is suggested that Tongkat Ali might help maintain a favorable balance between testosterone and estrogen, contributing to overall hormonal harmony.

  3. Additional benefits: Beyond its influence on SHBG, Tongkat Ali has been studied for its potential benefits on sexual function, fertility, and overall vitality. By promoting testosterone availability and potentially reducing SHBG, Tongkat Ali may enhance sexual desire, improve erectile function, and support reproductive health in both men and women. However, more robust clinical trials are necessary to confirm these effects.


Tongkat Ali shows promise as a natural remedy for promoting hormonal balance and supporting sexual health. By potentially reducing SHBG levels, Tongkat Ali may enhance free testosterone availability, which can have positive implications for libido, muscle growth, and overall well-being.

Preliminary studies are very promising, showing very little side effects taking anywhere from 200mg to 600mg of Tongkat Ali a day. Further research is needed to fully elucidate the mechanisms and determine optimal dosage and long-term safety.

As with any herbal supplement, it is crucial to consult with a healthcare professional before incorporating Tongkat Ali into your routine, especially if you have pre-existing medical conditions or are taking medications. Additionally, reputable sourcing and quality control are essential to ensure the efficacy and safety of any Tongkat Ali product.
