Tongkat Ali, also known as Eurycoma longifolia, is a plant that has been used in traditional medicine for centuries. It is native to Southeast Asia and is often used as a natural remedy for various health issues. In recent years, Tongkat Ali has gained attention for its potential to improve testosterone levels and sexual performance. In this blog, we’ll take a closer look at Tongkat Ali and explore its benefits, uses, and potential side effects.
What Is Tongkat Ali?
Tongkat Ali is a small evergreen tree found in the rainforests of Southeast Asia, particularly in Malaysia, Indonesia, and Thailand. Its roots are the most commonly used part of the plant, and they have been traditionally used to boost libido, improve energy levels, and treat a variety of ailments, such as malaria and fever. There are actually three other plant species that can refer to Tongkat Ali; Entomophthora apiculata, Polyalthia bullata, and Goniothalamus.
The more popular plant species in supplements is E. longifolia.
Other names for this plant can include:
- Malaysian Ginseng
- LongJack
- Eurycoma longifolia

Tongkat Ali Benefits:
One of the most popular uses for Tongkat Ali is to help promote testosterone levels. And some research and users indicate it may promote free and total testosterone levels. But this is indirectly through regulating estrogen levels. Supporting testosterone may also help promote strength and exercise performance and help promote fat loss. However, most of the potential health benefits of Tongkat Ali need more research.†
Tongkat Ali has also been shown to have a variety of other health benefits, including:
-
Improves sexual performance: Tongkat Ali has long been used as a natural aphrodisiac, and recent research has shown that it can improve sexual function in both men and women. In a study of 109 men, those who took Tongkat Ali supplements for four weeks reported improved erectile function and sexual performance.†
-
Increases muscle mass and strength: Tongkat Ali has also been shown to increase muscle mass and strength, making it a popular supplement for athletes and bodybuilders. One study found that men who took Tongkat Ali supplements for eight weeks experienced a significant increase in muscle mass and strength compared to those who took a placebo.†
-
Enhances cognitive function: Tongkat Ali has been shown to have neuroprotective effects and can improve cognitive function in both healthy individuals and those with cognitive impairment. In a study of older adults, those who took Tongkat Ali supplements for four weeks had improved cognitive function and memory recall.†
-
Reduces stress and anxiety: Tongkat Ali has been shown to have anxiolytic effects and can help reduce stress and anxiety. In a study of 63 adults, those who took Tongkat Ali supplements for four weeks reported reduced stress and anxiety levels compared to those who took a placebo.†
-
Lowers blood sugar levels: Tongkat Ali may also have blood sugar-lowering effects, making it a potential natural treatment for diabetes. In a study of 26 adults with type 2 diabetes, those who took Tongkat Ali supplements for five weeks experienced a significant decrease in fasting blood sugar levels.†
-
Enhances immune function: Tongkat Ali has also been shown to have immune-boosting effects, which can help improve overall health and prevent illness. In a study of 71 adults, those who took Tongkat Ali supplements for four weeks had improved immune function compared to those who took a placebo.†

Who Should Take It?
Tongkat Ali may be beneficial for certain individuals who are looking to improve their sexual function, increase their energy levels, or boost their muscle mass.
Here are some groups of people who may consider taking Tongkat Ali:

Athletes: Tongkat Ali may help athletes improve their performance by increasing muscle mass and boosting energy levels.†
-
Individuals with cognitive decline: Tongkat Ali has been shown to have neuroprotective effects and can improve cognitive function, making it a potential supplement for individuals with cognitive decline or memory problems.†

Stacks:
Tongkat Ali is a great stacking compound, which is why it’s commonly featured in natural testosterone booster blends. However, it has more uses than just as a testosterone booster. As always, whatever stack you choose will be based on your goals.

For example, to promote testosterone, you may want to stack it with Shilajit Extract.† Shilajit may also be beneficial as an adaptogen, like Tongkat Ali. †

If you want to put on some muscle mass while also increasing your strength, the combination of Tongkat Ali with Creatine may be a great option.† Other potential benefits of Creatine include:
- Support metabolic function†
- Enhance cognitive health†
- Promote physical and mental energy†

Some research indicates Tongkat Ali may help promote a positive mood and support stress management. To help these properties even further, you can try stacking with Ashwagandha. Ashwagandha is an adaptogen and also a great option for stress management.†
Other benefits of Ashwagandha can include:
- Promote a positive mood†
- Improve sleep quality†
- Promote brain health and cognitive function†
