Welcome to our knowledge center. We help you answer common questions on Tongkat Ali, compiled from hundreds of research papers and hours of research. 

What is Tongkat Ali?

Tongkat Ali is a natural herbal root from the plant Eurycoma Longifolia which is found in Malaysian and Indonesian rainfrorests.

Tongkat Ali is also commonly known as ‘Pasak Bumi’ in Indonesia, Cay Ba Binh in Vietnam, Pin Yin: 东革阿里 or Dōng gé ālǐ in China, ‘Longjack’ in the United States or Europe and ‘Malaysian Ginseng’ or `Akar Ali’ by locals.

The origin of the name “Tongkat Ali” comes from the Malay language that means Ali’s root.

Where does Tongkat Ali come from?

Tongkat Ali is consumed for centuries in Malaysia for health and general well-being.

The origin of Tongkat Ali as herbal remedies to treat various illnesses traced back to the 1600s and the 1800s when Malaysia was once a British colony.

This quintessentially Malaysian herb has had a great history and received many international coverage back in the early 2000s due to its massive potential that will revolutionize the health industry.

What are the potential health benefits of Tongkat Ali?

Multiple human clinical studies over the last 20 years have resulted in the following benefits: 

There are 12 potential benefits from scientifically-backed evidence on Tongkat Ali. Access to more scientific and research studies here.

What is Tongkat Ali in English or in other language?

Tongkat Ali is known as Longjack in English. In fact, it is one of the few herbs which has multiple household names in different languages, depending on which country you live in.

Tongkat Ali is also commonly known as ‘Pasak Bumi’ in Indonesia, Cay Ba Binh in Vietnam, Pin Yin: 东革阿里 or Dōng gé ālǐ in China, ‘Longjack’ in United States or Europe and ‘Malaysian Ginseng’ or `Akar Ali’ by locals.  Interestingly the Russians and Arabs refer to it as “Tongat Ali”.

The word “Tongkat Ali” root comes from a direct translation from the Malay language that means Ali’s root or Ali’s stick. It is also common for locals to refer to Tongkat Ali as Akar Ali, and easily pronounced as aka-rali in short.

Tongkat Ali and Long Jack. Are they the same?

Yes. Tongkat Ali and Long Jack are from the same plant, Eurycoma Longifolia.

Tongkat Ali is commonly known as Long Jack in the United States. 

The word “Long” comes from the word “Longifolia” which describes the physical attributes of the plant with long slender leaves. In Latin, “Longus” means long and “Folia” refers to the leaves.

What is Eurycoma Longifolia?

Eurycoma Longifolia is the scientific name of the Tongkat Ali plant that is found in remote rainforests of Malaysia.

This plant is often referred to as Eurycoma Longifolia by researchers and scientists. However, it is not commonly known by that name amongst general consumers.

The word “Eurycoma Longifolia” comes from Greek and Latin words.

In Greek, the word “eurys” originally means broad while “come” means a tufted bush, which describes the plant’s physical attributes.

The word Eurycoma refers to the growth habit of its compound leaves that spirals out at the tip of its slender trunk in a large dense rosette.

In Latin, “Longus” means long and Folia refers to the leaves, so the word Longifolia describes the compound leaflets that are often long and slender. 

What are the main ingredients of Tongkat Ali?

Major bioactive compounds in Tongkat Ali are eurycomanone, glycosaponin, polysaccharide and crude protein. In it’s natural form, these bioactive ingredients work together to deliver health benefits.

The Tongkat Ali root has the highest level of bio-active ingredients compared to the branch, leaves and other parts of the Tongkat Ali plant.

Which bioactive compounds in Tongkat Ali are vital to health?

Eurycomanone contains quassinoids and is considered one of the most vital bioactive compounds in Tongkat Ali. It’s unique molecular structure is widely researched for medicinal and adaptogen properties.

The amount of eurycomanone that can be extracted from Tongkat Ali is between 1% to 5% depending on the batch production and quality of Tongkat Ali plants. A healthy plant can produce higher eurycomanone.

Several studies found that eurycomanone significantly increased testosterone production and sperm production.

Does Tongkat Ali contain protein?

Studies showed that Tongkat Ali plants found in Malaysia contain crude proteins between 15.5% to 39.9%. The amount of crude protein varies on the soil quality and Tongkat Ali in the state of Pahang usually has higher crude protein content.

Physta® Tongkat Ali contains high crude protein content, averaging more than 22% due to the standardized water extraction technology.

Does Tongkat Ali contain gluten and is it gluten-free?

Tongkat Ali (Eurycoma Longifolia) does not contain gluten, or wheat proteins.

Gluten or wheat proteins is found in grains – such as wheat, barley, rye, and a cross between wheat and rye called triticale. These include any species of wheat (i.e durum, spelt, khorasan, emmer and einkorn), barley, rye and some oat cultivars. 

Studies showed that Tongkat Ali contains crude proteins and amino acids, and not wheat protein.

As Tongkat Ali is gluten-free, this makes it ideal if you have celiac disease and other medical conditions associated with gluten.

How is Tongkat Ali consumed?

Tongkat Ali is one of the most functional herbs that is used in many applications since its modern-day discovery.

Here are three common applications of Tongkat Ali:

  1. Functional Ingredient – as an active ingredient or additive in coffee or tea. Widely available and consumed daily in Asia for centuries. 
  2. Performance Ingredient – as pre-workout drinks or supplements used by fitness professionals and sports amateurs to deliver a competitive edge. Often mix with other herbs to maximize muscle growth and recovery, energy and stamina.
  3. Dietary Supplement – mainly available in capsule form and consumed as part of daily dietary supplements to revitalize general health and vitality.

Yellow, Red, and Black Tongkat Ali. Are they the same?

There are three types of Tongkat Ali roots coming from different plants:

  • Yellow Tongkat Ali – Eurycoma Longifolia
  • Black Tongkat Ali – Polyalthia Bullata
  • Red Tongkat Ali – Stema Tuberosa

 

The most popular and widely researched is the yellow Tongkat Ali (i.e Eurycoma Longifolia) due to its bio-active compounds that are beneficial and safe for your health. These are sourced from Malaysia within tight Government regulations to meet the Malaysian Standard (MS 2409:2011) for Tongkat Ali.

Black and Red Tongkat Ali have mixed-reviews on its efficacy and safety, but still sold in the market in smaller quantities. Most of black and red Tongkat Ali are from sourced from Indonesia with high lead and mercury content that can be harmful to health.

What is the difference between Tongkat Ali and Panax Ginseng?

Tongkat Ali and Panax Ginseng come from different family trees with roots that exhibit various health benefits. 

  • Tongkat Ali (or Malaysian Ginseng) comes from a plant Eurycoma Longifolia belonging to family tree known as Simaroubaceae
  • Panax Ginseng comes from a family tree known as Araliaceae

Both of these plants are native to different parts of the world.

  • Tongkat Ali are found and harvested in Malaysia and Indonesia
  • Panax Ginseng are cultivated in Northeast of China and Korean Peninsula

However, Panax Ginseng and Tongkat Ali contain one similar bio-active ingredient known as saponin that is associated with various biological activities, such as anti-inflammatory, cholesterol-lowering and anti-cancer properties.

Can Tongkat Ali benefit women?

The most misconception of Tongkat Ali is that it can only benefit men. This is due to traditional beliefs that Tongkat Ali is consumed to revitalize men’s health and libido.

However, modern science and research on Tongkat Ali showed that the hormone-inducing mechanism promotes wellness for women too.  In fact, Tongkat Ali is widely used as sports supplements by athletes and sports professionals to increase workout performance. And that benefits both men and women without any downsides to women.

Multiple clinical trials have shown that Tongkat Ali can regulate hormones in women, supports weight loss by reducing fat and increasing muscle strength, and reduce stress and confusion.

Are Tongkat Ali safe for vegetarians?

Most Tongkat Ali grows naturally in wild rainforests and consumes natural nutrients from the earth. If you are already on a plant-based diet, Tongkat Ali can supplement nutrients that your body needs to promote better vitality and general health.

Brands such as AKARALI contains 100% Tongkat Ali extract from Eurycoma Longifolia (natural plant) in vegetarian-friendly capsules.

How does Tongkat Ali work? And does it work?

  1. Tongkat Ali contains ingredients such as eurycomanone,  a family of quassinoids and alkaloids that work by activating hormone-inducing actions in our body.
  2. Tongkat Ali activates Luteinzing Hormones (LH) that stimulates the Leydig cells in your testicles to produce testosterone. In women, the Luteinizing Hormones (LH) triggers the creation of steroid hormones from the ovaries and that helps with menstrual cycle and ovulation.
  3. Tongkat Ali decreases the sex hormone binding globulin (SHBG) which in turn, delivers higher production of testosterone. SHBG rises when your testosterone level is low.
  4. At the same time, Tongkat Ali reduces cortisol, the stress hormone that lowers the testosterone in our body.
  5. The mechanism of actions collaboratively increase production of “free testosterone” in our body.
  6. Therefore, increased free testosterone from Tongkat Ali provides more energy, improved mood, improved sexual libido, more sperm motility, stronger muscle growth, reduced body fat, increased immune system and reduction of stress.

Yes, Tongkat Ali is proven to benefit health in many aspects from years of human clinical trials and studies. More than 400-500 human test subjects have been tested with positive results.

Are Tongkat Ali benefits validated by science?

There are more than 100 research papers and clinical trials on Tongkat Ali involving thousands of human tests to investigate its efficacy on human health. Human and clinical trials have both provided sufficient evidence on Tongkat Ali’s effectiveness to benefit health in many ways. Scientists such as Dr. Annie George, Dr. Shawn Talbott, Professor Dr. Anthony Sinskey, Professor Hirokawa and others have long dedicated their research to Tongkat Ali.

What is premium Tongkat Ali?

Premium Tongkat Ali is an embodiment of carefully handpicked Tongkat Ali roots using the best extraction technology.

The finest Tongkat Ali contains one of the highest bio-active ingredients which can only be found in roots that are more than 4 to 5 years old. More often than not, these roots are chromatography tested to ensure only the best roots are selected by trained artisans. 

The potency, efficacy and scarcity define the premium price, which explains why authentic Tongkat Ali prices have skyrocketed in recent years.

Where can I buy the best Tongkat Ali?

Where can I find the most potent Tongkat Ali?

The most potent Tongkat Ali can be found in the virgin rainforest of the state of Pahang, Malaysia and in selected regions of Borneo. A study showed that Tongkat Ali found in Pahang contains higher crude protein (39.3%) compared to Tongkat Ali found in Perak (15.5%).

What is clinically tested Tongkat Ali?

A clinically tested Tongkat Ali refers to Tongkat Ali products that have undergone clinical trials or clinical pre-trials where Tongkat Ali extracts are tested on humans (eg: patients or volunteers) with validated results by qualified medical professionals and scientists.

Clinically tested Tongkat Ali is touted to be the best as it delivers optimal health benefits without side effects.

What is standardized Tongkat Ali extract?

Standardized Tongkat Ali extract is an extraction process that ensures bioactive components from Tongkat Ali (such as eurycomanone, eurypeptides, glycosaponin, polysaccharides) are produced in a specific and guaranteed amount – usually expressed as a percentage.

This ensures consumers receive the same level of quality, with the same concentration of bioactive components from every batch produced by the manufacturer.

A standardized extract is regarded as the gold standard in the herbal industry compared to the traditional 200:1 or 400:1 extraction method.

The 200:1, 400:1 or even 500:1 extraction ratio does not guarantee the same level of concentration of the bio-active components that can be produced from a standardized extraction method.

MIT-formulated Physta® Tongkat Ali uses standardized extraction method with hot-water and freeze-dried technology since 2008 with higher potency than other known methods.

What is the recommended Tongkat Ali dosage?
