NutraBio Tongkat Ali (Longjack)

200mg of tongkat ali (Eurycoma longifolia) per capsule, 60 servings. Single ingredient, no fillers or excipients.

⚠ The number that actually matters is not the milligrams

This is the most useful thing on this page, and it separates the tongkat ali that works from the tongkat ali that does not.

The active compound is eurycomanone, a quassinoid found in the root. Everything the research is built on comes back to it.

And the concentration varies enormously between products. Tongkat ali extracts are described by their extraction ratio — 100:1, 200:1 and so on — and separately by the percentage of eurycomanone they contain. Those are different measures, and only the second one tells you anything useful.

What to look for	A stated eurycomanone percentage — commonly 2% to 10%
What the research used	Extracts standardised toward the higher end of that range
What tells you little	An extraction ratio like "100:1" with no eurycomanone figure

So 200mg of a well-standardised extract can contain more active compound than 500mg of a weak one. If a label gives no eurycomanone percentage, you cannot judge the dose — and that is true of a great many tongkat ali products on the market.

Same principle as the standardisation issues on our Alpha-GPC and Milk Thistle pages. It catches people out repeatedly.

What the research actually shows

Tongkat ali has more human research behind it than most botanical testosterone products, and it is worth separating the credible from the overstated.

Better supported:

Testosterone increases in men with low baseline levels. This is the consistent finding — effects appear in men who are already low, particularly older men and those under significant stress
Cortisol reduction. Several trials report improved cortisol-to-testosterone ratios, and the stress angle may be a substantial part of how it works
Wellbeing and mood under stress, which has been examined in its own right

Less supported:

Raising testosterone in men who already sit in the normal range. As with ashwagandha, this appears to correct suppression rather than push levels above normal
Direct muscle or strength gains independent of the hormonal effect

The honest framing: tongkat ali is among the better-evidenced natural options in this category — and the category as a whole is one where effects are modest and depend heavily on your starting point. If you are a healthy young man with normal testosterone, expect little.

Give it eight to twelve weeks

Worth stating clearly because it is the most common reason people conclude it does nothing.

Hormonal changes are gradual. Trials on tongkat ali typically run four to twelve weeks, and the more substantial findings come from the longer end. Libido and mood effects are often reported earlier; measurable hormonal change takes longer.

Taking it for two weeks and stopping tells you nothing.

Specs

Tongkat Ali	200mg per capsule (Eurycoma longifolia)
Servings	60
Other ingredients	None beyond the capsule
Label	Fully disclosed, no proprietary blends
Testing	Third-party tested, published at checkmysupps.com

⚠ Heavy metals are a genuine concern with this botanical. Tongkat ali is grown in Southeast Asia, and independent testing of imported extracts has historically found mercury and lead contamination in some products. Third-party testing is not a nicety here — it is the main reason to buy from a brand that publishes results rather than the cheapest available option.

How to take it

One capsule daily. Research doses commonly sit in the 200 to 400mg range.
In the morning, matching your natural testosterone rhythm.
With food, which reduces the stomach upset some people report.
Consistently for eight to twelve weeks before judging it.
Cycling is commonly practised — five days on, two off, or several weeks on with a break — though the evidence for needing to is limited.
Not late in the day. Some people find it mildly stimulating and report disturbed sleep.

Who this is for

Men over about 35, where age-related decline makes a low baseline more likely
Anyone under sustained stress, given the cortisol findings
Men with confirmed low testosterone on bloodwork, alongside medical guidance
People who want a single standardised ingredient rather than a proprietary test blend
Anyone who wants published third-party testing on a botanical where contamination is a real issue

Who this is not for

Healthy young men with normal testosterone. The evidence points to correcting low levels rather than raising normal ones — and sleep, bodyweight, training and getting vitamin D and zinc right matter considerably more.

Anyone who has not had bloodwork. Testing total and free testosterone tells you whether there is anything to correct.

Anyone with a hormone-sensitive condition, including prostate concerns, without speaking to a doctor.

Women, without medical guidance — the research is overwhelmingly in men.

Anyone taking hormonal medication, or medication for blood pressure or diabetes, without checking.

Tested athletes should check their federation's current list before use.

Not for anyone under 18, pregnant or nursing.

Stack it with: ashwagandha — the two work on the same problem from different angles, ashwagandha by lowering cortisol and tongkat ali more directly. Both depend on stress or a low baseline being your limiting factor.

Frequently asked questions

What should I look for on a tongkat ali label?
A stated eurycomanone percentage. Extraction ratios like "100:1" tell you little on their own — 200mg of a well-standardised extract can contain more active compound than 500mg of a weak one.

Does it raise testosterone?
In men with low baseline levels, the evidence is reasonably consistent. In men already in the normal range, it appears to correct suppression rather than push levels higher.

How long before it works?
Eight to twelve weeks. Libido and mood effects are often reported earlier; hormonal change is gradual.

Why does third-party testing matter here?
Tongkat ali is grown in Southeast Asia, and independent testing has historically found mercury and lead contamination in some imported extracts. Published lab results are the main reason not to buy the cheapest option.

When should I take it?
Morning, with food. Some people find it mildly stimulating late in the day.

Do I need to cycle it?
Cycling is commonly practised, though the evidence that it is necessary is limited.

Can I take it with ashwagandha?
Yes, and they are frequently paired — ashwagandha lowers cortisol while tongkat ali acts more directly. Both depend on stress or a low baseline being the issue.

Should I get bloodwork first?
It is worth it. Total and free testosterone tell you whether there is anything to correct — and whether this is likely to do anything for you.
