Where does
Tongkat Ali grow in the jungles ?

Tongkat Ali can be found everywhere in the deep rainforests. However, from what we've learned from the natives who have harvested them for decades, different types of Tongkat Ali can only grow in a certain parts of the jungle.

For example, Red Tongkat Ali is found up the slopes while Black Tongkat Ali thrives well in nearby swamps and as for Ginseng Tongkat Ali, it is commonly found within the same vicinity of Yellow Tongkat Ali.  Requirements to harvest any type of Tongkat Ali would need to be at least 5 years of age

The different levels of eurycomanone present in Tongkat Ali
from different Malaysian states

Soil & geography is crucial for Tongkat Ali's bioactive ingredient Eurycomanone to be present & strong. Which is what Tongkat Ali is prized for. There are several factors that affect the percentages in Eurycomanone levels in Tongkat Ali. For example, the geography of the island population, coastal population, & hill forest population.


The difference in Eurycomanone levels in Tongkat Ali found all over the states of Malaysia are also the result of different geographical locations, altitudes, temperatures, & moisture. However, there are still many other considerations to be taken & still more research to be done.

Graph below depicts the percentage of eurycomanone detected in Tongkat Ali in each Malaysian State.

Each part of Tongkat Ali contains different levels of eurycomanone 

Tongkat Ali Root also contains compounds Quassinoids & Alkaloids. The root is the only part that contains Eurycomanone & while other parts of the plant may also contain small traces of it

Now that you have a better understanding of Tongkat Ali,
let's go into questions people often ask

How does Tongkat Ali work in our body ?

As testosterone ages become bound to serum globulin and is not available for cell receptor sites where it is necessary to initiate sex stimulation centers in the brain. The component in the bloodstream that makes testosterone inactive-free is called sex hormone-binding globulin (HFBG). Too much estrogen can boost SHBG production and block testosterone receptor sites. The average 54-year-old man often has higher estrogen rates than the average 59-year-old woman. While some estrogens are a hormone needed for men, too contribute to a broad spectrum of health, weight gain and libido problems. Because of the similarities in the chemical structure, elevated serum estrogen levels also deceive the brain by thinking that enough testosterone is produced, thus slowing down the natural production of testosterone. In order for testosterone to produce positive health effects, it must be preserved in its free form in the bloodstream. Bonded testosterone is unable to be captured by testosterone receptors on cellular membranes. For aging men, it is desirable to remove excess levels of SHBG and estrogen whilst stimulating free testosterone at the level of a young man. Tongkat Ali is a natural way to boost bio-available testosterone while also lowering levels of SHBG and estrogens in aging men. Results from studies to date have confirmed that Tongkat Ali could help in the following areas:

In summary, these combined effects position Tongkat Ali as perhaps the safest and most effective herbal testosterone enhancing medicinal plant available today. It is particularly suitable for slowing down or reversing the so called male andropause that occurs in middle-age and is of benefit for athletes and bodybuilders looking for a natural supplement without side-effects.

If Tongkat Ali increases my testosterone, won't that make me aggressive ?

On the contrary, Tongkat Ali actually reduces aggressiveness and promotes a sense of calm and confidence. This anxiety relieving effect was also demonstrated in animal studies in that the test rats exhibited a reduced tendency to fight and performed better (improved motor skills) in tests designed to mimic stress and anxiety. Tongkat Ali does not contain any testosterone in itself as it acts only as a precursor to prompt the body to supply more of its own testosterone and this also includes improving the useable or free “good” testosterone within physiological normal parameters. In this way we are still ourselves, just ourselves on a particularly more virile and heightened energy day especially suited to androgenic activities such as fitness and body building or sex.

Conversely certain body builders who inject large doses of synthetic testosterone hormone actually reduce their bodies own production and may experience increased aggression as well as hair loss, reduction in testicular size, outbreaks of acne and heart problems among other issues.

What's your opinion about 100:1 and 200:1 ratios of Tongkat Ali extracts ?

Tongkat Ali extract must be tested for its Eurycomanone content and not for the "ratio method" that is unverifiable. It's unfortunate but those claiming to have Tongkat Ali extraction ratios of 100:1, and even the 200:1 are false and only propagated by marketing people, not scientists/phytochemist.

Also absent from all these companies is any mention of studies on the active ingredient marker in Tongkat Ali, Eurycomanone. Eurycomanone is the prominent bioactive quassinoid present in Tongkat Ali that is used as a marker and should be present @ >2% Eurycomanone for a daily dosage of 600mg to 900mg. The Eurycomanone concentration of the extract and daily dosage needs to be adjusted accordingly for an effective product. For example, a product that contains only 75mg of a 3% Eurycomanone extract (claiming to be 100:1) will be below the therapeutic dosage and thus the concentration of the original extract is meaningless when the dosage used in the capsule is too low.

Another issue is that the colour of an extract does not offer any clue to its quality or concentration, as a darker coloured extract may indeed be only "burnt" during excessive heating, especially by poor quality drying processes with subsequent loss of properties due to unregulated heat. Assay for glycosaponins is a standard in phytochemistry especially for products that elicit an effect on the male reproductive system. For example the majority of known active ingredients in Korean Ginseng are also glycosaponins. Finally, when you purchase a product from a company claiming a 200:1 extract then you are likely buying a reverse engineered extract that may not contain any Tongkat Ali extract at all, but in fact a different herb that contains similar organoleptic (taste, smell etc.) characteristics.

Numerous commercial Tongkat Ali supplements claim “extract ratios” from 1:20 to 1:200 without any information about bioactive constituents, extraction methodology (e.g. ethanol versus water), or extract purity. Alcohol extracts of eurycoma have been studied in mice for antimalarial effects of concentrated eurycomalactone but also exhibit toxic effects at high doses (LD50 at 2.6 g/kg), which would preclude safe use in humans as a long-term dietary supplement. In contrast, hot-water root extracts standardized for known bioactive components (1% eurycomanone, 22% protein, 30% polysaccharides, 35% glycosaponin) have been demonstrated to be extremely safe at high doses and for long-term consumption.

Properly standardised hot-water extracts have a distinctly bitter taste due to the presence of quassinoids, which are recognized as some of the bitterest compounds in nature Tongkat Ali extracts that do not taste bitter are either not true Eurycoma Longifolia root (there are many commercial examples of “fake” Tongkat Ali extracts) or are sub-potent in terms of bioactive constituents, and thus would also be expected to have low efficacy. Because of Tongkat Ali’s reputation for libido benefits, there are several examples of dietary supplements labeled as Eurycoma Longifolia, but containing none of the actual root, and instead being “spiked” with prescription erectile dysfunction drugs including tadalafil/Cialis, sildenafil/Viagra, and vardenafil/Levitra.

Does Tongkat Ali have any side effects ?

Side effects varies in each person's body. These are common. Some may experience dizziness or headaches after consuming. It lasts for a short while and goes away. Typically, one experience this as the herb is still new to the body and as its strong, it is taking its time to adjust. It is always recommended to start with a smaller dosage for any type you are taking and slowly progress you get used to it. Usually by the 2nd or 3rd week of taking Tongkat Ali, the dizziness or headaches will no longer be present. Other than that, it is also reported that some have stronger odour for the urine and some may experience heatiness. This is normal as well and we normally recommend to take more water while taking Tongkat Ali

There are so many choices, which should I be taking ?

Our Tongkat Ali products come in slices, powder, tea, coffee, capsules and extract. Our large range of products is catered to serve lifestyle. If you are a busy person that doesn't want too much hassle, you may opt for the capsules or extract or tea bags.  If prefer using it for longer periods and  having the time to boil it, you can take the slices or powder. All are 100% pure Tongkat Ali with no added ingredients. As with all other types of traditional herbs, Tongkat Ali should always be taken after meals. Make sure to not take any of these on an empty stomach as Tongkat Ali is strong and those with weak stomach may feel uncomfortable

What is the dosage I should take ?

The Tongkat Ali dosage recommended for consumption increases with age and it is also based on the underlying hormonal deficiency. As such, the dosage of a 65 years old will need to be higher compare to a 35 year old. For more information on our individual Tongkat Ali product dosages please see the description on each individual products

How long does Tongkat Ali take to take effect ?

It all depends on your age as well as how active you are in sports, gym, or daily activities. The more active you are, the results will come faster (sometimes within 2 weeks). If you are not active and more sedentary, it may take up to 3 - 4 weeks to feel energised
