The best fadogia agrestis supplements in 2026 state the extract ratio, the milligrams per capsule and how many capsules make a serving, so you can work out what a day costs. We compared six US options on those numbers, read from each brand’s own product page in September 2026, and we checked what the research can and can’t support. Our pick is Eternal Elixir Tongkat Ali + Fadogia 2010mg: 1,500mg of 10:1 fadogia stem extract plus 500mg of 200:1 tongkat ali per serving, at $0.67 a serving. For the lowest cost per day on fadogia alone, Nutricost Fadogia Agrestis is about $0.10.
Quick answer
- Our pick: Eternal Elixir Tongkat Ali + Fadogia 2010mg. 1,500mg fadogia (10:1) and 500mg tongkat ali (200:1) per 3-capsule serving, 90 capsules, $19.99.
- Lowest cost per day: Nutricost Fadogia Agrestis, 600 mg of 10:1 extract per capsule, 240 capsules for $24.97.
- Most testing detail on the page: Double Wood Fadogia Agrestis, with a linked certificate of analysis and named identity tests.
- What hasn’t been shown: fadogia has no published human trials. Every effect claimed for it comes from rat studies.
One fact frames everything below. A PubMed search for “Fadogia agrestis” in September 2026 returned 10 records, and none of them is a human trial. Tongkat ali, the ingredient fadogia is most often paired with, has randomized human trials. That is why our pick is a combination, and why we also list a tongkat-only option for readers who decide fadogia isn’t worth it.
Best fadogia agrestis supplements 2026 compared
Prices are one-time prices on each brand’s own site, as of Sep 2026. Cost per day uses the brand’s own label serving. Cost per 1,000 mg is the bottle price divided by the total fadogia extract in the bottle, which only compares fairly between extracts of the same ratio.
| Rank | Product | Fadogia per serving | Tongkat ali per serving | Capsules | Price | Cost per day | Cost per 1,000 mg fadogia | Buy |
|---|---|---|---|---|---|---|---|---|
| 1 | Eternal Elixir Tongkat Ali + Fadogia 2010mg | 1,500mg (10:1) | 500mg (200:1) | 90, 3 per serving | $19.99 | $0.67 | $0.44 | View product |

| 4 | The Vitamin Shoppe Fadogia Agrestis | 600 mg (10:1) | None | 60, 1 per serving | $19.99 | $0.33 | $0.56 | Vitamin Shoppe |
| 5 | Toniiq Tongkat Ali 200 & Fadogia 30 | 300 mg (30:1) | 300 mg (200:1) | 120, 1 per serving | $33.30 | $0.28 | Not comparable (30:1) | Toniiq |
| 6 | Eternal Elixir Tongkat Ali 200:1 2000mg | None | 2,000mg (200:1) | 90, 3 per serving | $29.99 | $1.00 | No fadogia | View product |
Two things stand out. Fadogia on its own is cheap: three of the single-ingredient bottles cost $0.33 a day or less. And the doses cluster at 600 mg of 10:1 extract, which is a manufacturer convention rather than a dose tested in people, because no human dose has ever been tested. For why label doses and trial doses so often diverge, see our supplement dose gap report.
How we ranked these six
Eternal Elixir makes Tongkat Ali + Fadogia 2010mg, and it is our pick. It sits first, and our tongkat-only formula sits sixth as the alternative for readers who skip fadogia. The four other brands are ordered on the same checks, read from each brand’s own page:
- Label clarity. A stated extract ratio, milligrams per capsule and capsules per serving.
- Cost per day and per 1,000 mg of extract. Worked out from the label serving, never from a guess.
- Identity and purity testing you can read. Fadogia is a low-volume botanical, and a 2019 analysis found that 5 of 17 supplements sold as fadogia had none of the plant’s marker compounds detected. A named identity test matters here more than in most categories.
- Whether the bottle includes an ingredient with human data. Tongkat ali has randomized trials. Fadogia does not.
What we did not do: we sent no bottles to a lab, and nobody here took six fadogia products and compared how they felt. For the mechanism and dosing background, see our guide to fadogia agrestis benefits and dosage.
The 6 best fadogia agrestis supplements, reviewed
1. Eternal Elixir Tongkat Ali + Fadogia 2010mg: our pick
Tongkat Ali + Fadogia 2010mg comes in a 90-capsule bottle with a 3-capsule label serving, so each bottle holds 30 servings. Each serving provides 1,500mg of Fadogia agrestis 10:1 stem extract, 500mg of Tongkat Ali 200:1 root extract and 10mg of BioPerine black pepper extract, with rice flour and a cellulose capsule. At $19.99, reduced from $59.99, that is $0.67 a serving and $0.44 per 1,000 mg of fadogia extract.
Why it ranks first: it is the only product here that pairs a full fadogia serving with a meaningful dose of tongkat ali, the ingredient that has human trials. Toniiq’s combination has 300 mg of each. It also has the lowest bottle price in the comparison. And the product page is plain about the limits: it says fadogia lacks human clinical trials, that a rat study reported adverse testicular changes, and that this exact combination has not been tested for absorption or outcomes.
Who it suits: people who were going to stack fadogia with tongkat ali anyway and would rather buy one bottle than two.
Who it doesn’t suit: anyone who wants the cheapest fadogia per milligram, where Nutricost costs less. It also has the highest fadogia dose here, which cuts both ways for an ingredient with no human safety data. If that bothers you, the tongkat-only formula at #6 is the cautious route. A blend also means you can’t change the two doses independently.
2. Nutricost Fadogia Agrestis: lowest cost per day
Nutricost’s bottle holds 240 capsules, and one capsule is one 600 mg serving of 10:1 extract, so a bottle lasts 240 days. At $24.97 that is about $0.10 a day and $0.17 per 1,000 mg of extract, well under half what the other 10:1 bottles here cost per milligram. Nutricost says the capsules contain no other active ingredients, that its products are tested by an independent accredited lab, and that they are made in a GMP-compliant facility. It offers a 60-day money-back guarantee.
Who it suits: buyers who want to try fadogia alone at the lowest cost. More on the brand in our Nutricost review.
Who it doesn’t suit: anyone who wants to read batch test results before buying, because the product page doesn’t link a certificate of analysis. A 240-day supply is also a long commitment to an ingredient with no human trials.
3. Double Wood Fadogia Agrestis: most testing detail on the page
Double Wood’s bottle holds 180 capsules at 300 mg each, which the page describes as 90 servings of 600 mg. The directions start at one 300 mg capsule a day and allow two after the first week. At $29.95 that is $0.33 a day at two capsules, and $0.55 per 1,000 mg. Two- and three-bottle packs cost $56.91 and $80.87.
The page links a certificate of analysis and third-party test results, and says every batch is tested by an ISO/IEC 17025-accredited lab, with identity checked against reference plant material by HPLC and TLC fingerprinting. Given the 2019 finding that some fadogia products contained none of the plant’s marker compounds, that identity check is the strongest reason to pick this bottle. One caution: a line in the page’s FAQ says the certificate verifies 600 mg per capsule, which conflicts with the 300 mg per capsule stated elsewhere on the same page. Our Double Wood Supplements review covers the brand’s wider range.
Who it suits: buyers who want to see identity testing before they take a lightly researched botanical.
Who it doesn’t suit: anyone comparing on price per milligram, where it costs more than three times Nutricost’s figure.
4. The Vitamin Shoppe Fadogia Agrestis: easiest to buy in a store
The Vitamin Shoppe’s own-brand bottle holds 60 vegetable capsules, and the supplement facts panel lists one capsule as 600 mg of 10:1 fadogia stem extract, for 60 servings. At $19.99 that is $0.33 a day and $0.56 per 1,000 mg. The label says to take one capsule a day, preferably with a meal. It is also sold in The Vitamin Shoppe’s US stores, so you may be able to pick it up the same day.
Who it suits: people who want a short, two-month trial without ordering online.
Who it doesn’t suit: anyone planning longer use, where Nutricost’s 240-capsule bottle costs about a third as much per day.
5. Toniiq Tongkat Ali 200 & Fadogia 30: lowest-dose combination
Toniiq’s combination holds 300 mg of 200:1 tongkat ali extract and 300 mg of 30:1 fadogia extract per serving, and the directions say to take one capsule daily with food. The bottle holds 120 capsules, so $33.30 covers 120 days, or $0.28 a day. Subscribe and save brings it to $28.31. The linked certificate for lot 5214 measured 6.15 mg of eurycomanone, tongkat ali’s marker compound, per capsule, against a minimum of 6 mg. The page shows free shipping over $49 and a 60-day money-back guarantee.
A 30:1 ratio is three times as concentrated as 10:1 by the brand’s own measure, so 300 mg here isn’t directly comparable with 300 mg of a 10:1 extract. Neither ratio is standardized to a named fadogia marker compound. Toniiq’s single-ingredient Fadogia 30:1 was listed as sold out when we checked.
Who it suits: cautious first-time users who want both herbs at a low dose in one daily capsule.
Who it doesn’t suit: anyone who wants a full 500 mg or more of tongkat ali, which our combination at #1 provides.
6. Eternal Elixir Tongkat Ali 200:1 2000mg: best fadogia-free alternative
If the evidence section below talks you out of fadogia, this is the bottle we suggest instead. Tongkat Ali 200:1 2000mg provides 2,000mg of Eurycoma longifolia root extract at a declared 200:1 ratio per 3-capsule serving, with rice flour and a cellulose capsule. The bottle holds 90 capsules, or 30 servings, at $29.99, reduced from $59.99, which is $1.00 a serving.
Our product page adds a caveat: a 200:1 ratio describes concentration and does not make this product equivalent to the standardized extracts used in published trials. Tongkat ali still has the human data that fadogia lacks.
Who it suits: readers who want the same goal from an ingredient with human trials behind it. Our ranked comparison of tongkat ali supplements sets it against other US brands.
Who it doesn’t suit: anyone set on trying fadogia itself, since it contains none.
Does fadogia agrestis actually work? What the research shows
The honest answer is that nobody knows for people, because nobody has run a human trial. Here is what each common claim rests on.
| Claim | What the evidence is | Evidence level |
|---|---|---|
| Fadogia raises testosterone | Male rats given stem extract for 1 to 5 days, one research group | Animal only |
| Fadogia is safe at label doses | No human safety data. Rat studies over 28 days reported testicular and liver enzyme changes | Not shown in humans, animal caution |
| Fadogia supplements contain fadogia | A 2019 lab analysis: 12 of 17 products had the plant’s phenolic compounds, 5 had none detected | Product testing |
| Tongkat ali supports testosterone levels | Randomized human trials and a 2022 meta-analysis | Human trials, mixed preparations |
| Fadogia plus tongkat ali works better together | No study of the pair | Not shown |
The rat studies behind every fadogia claim
Nearly all of the fadogia literature comes from one group at the University of Ilorin in Nigeria. In the 2005 study that started the “fadogia raises testosterone” idea, published in the Asian Journal of Andrology, male rats were given a water extract of the stem at 18, 50 or 100 mg per kg of body weight, and their testosterone and mating behavior were measured over 5 days. Testosterone rose in all dosed groups.
The same group then dosed rats for 28 days and reported changes in testicular function markers at every dose. The authors described those changes as signs of adverse effects on the testes, with partial recovery at the lowest dose after 10 days off. A 2009 paper from the group, using the same doses and duration, reported liver and kidney enzyme changes. A 2023 study in Reproductive Sciences again used rats.
Rat results don’t tell you what happens in people, in either direction. They don’t prove fadogia works, and they don’t prove it harms. They are a reason for caution, which is also why the sports supplement brand Momentous says it pulled fadogia from its range in 2024 after its science team judged the research wasn’t progressing.
Tongkat ali: human trials, with caveats
Tongkat ali has been tested in people. In a 2013 trial by Talbott and colleagues, 63 moderately stressed adults took a standardized tongkat ali root extract or a placebo for 4 weeks. In the tongkat group, salivary cortisol exposure fell 16% and testosterone status rose 37%, and some mood scores improved. A 2022 meta-analysis by Leisegang and colleagues pooled five randomized trials and found a significant rise in total testosterone in men taking tongkat ali.
Those trials used specific standardized extracts, and results depend on the preparation. That caveat applies to every tongkat product here, ours included. For other options with human data, see our natural testosterone booster comparison.
Tongkat ali vs fadogia agrestis: which is better?
| Fadogia agrestis | Tongkat ali (Eurycoma longifolia) | |
|---|---|---|
| Part used | Stem | Root |
| Human trials | None found on PubMed | Randomized trials and a 2022 meta-analysis |
| Safety data in people | None | Reported in its trials, for the extracts they used |
| Common label dose here | 600 mg of 10:1 extract | 300 mg to 2,000mg of 200:1 extract |
| Lowest cost per day here | $0.10 (Nutricost) | $0.28 with fadogia included (Toniiq) |
| Our product | In Tongkat Ali + Fadogia 2010mg | Tongkat Ali 200:1 2000mg, and in the combination |
On evidence, tongkat ali. It has randomized human trials and a meta-analysis, while fadogia has rat studies. On price, fadogia alone is cheaper: $0.10 a day for Nutricost against $1.00 a serving for our 2,000mg tongkat ali. Many people pair the two, which is what our combination at #1 does. If you want only one, tongkat ali is the one with human data behind it.
Why identity testing matters more for fadogia
Fadogia agrestis is a wild West African shrub, not a farmed crop with a long supply history. That makes it easier to sell something that isn’t what the label says. In 2019 a team at the University of Mississippi developed a lab method to measure 11 of the plant’s marker compounds, then tested 17 supplements sold as fadogia. Twelve contained the plant’s phenolic compounds, at 0.3 to 2.7 mg a day at the label dose. In the other five, none were detected.
The study didn’t name brands, and it doesn’t tell you which of today’s products passed. It does tell you what to ask for. A certificate of analysis that confirms identity against reference plant material, as Double Wood describes, answers the question that matters most. A generic “third-party tested” badge doesn’t. Our own product page lists the extract, ratio and plant part for each ingredient, and says the finished blend has not been clinically tested.
Fadogia agrestis side effects: what is and isn’t known
There is no human safety data for fadogia, so nobody can give you a side effect rate. What exists is the rat work described above:
- Testicular markers. After 28 days at every dose tested, the rats showed changes the authors called adverse effects on testicular function, with only partial recovery at the lowest dose 10 days after stopping.
- Liver and kidney enzymes. A 2009 study from the same group, at the same doses for 28 days, reported enzyme changes in the liver and kidneys and signs of cell membrane damage, without visible organ swelling or deaths.
- What’s missing. No study has looked at long-term use, at human doses, or at fadogia combined with other herbs.
That is thin evidence in both directions. It is also why we suggest starting at the label serving or below, not stacking several fadogia products, and talking to your doctor if you have any existing health condition or take regular medication.
Who should skip fadogia agrestis
- Anyone uneasy about the rat testicular findings. That is a reasonable response to the evidence.
- Anyone taking prescription medication, particularly anything that affects hormones, without talking to a doctor first.
- Anyone pregnant or breastfeeding, and anyone under 18.
- Athletes who are drug tested should check with their sport’s governing body before using any herbal testosterone product.
If you want the same goal from a better-studied starting point, tongkat ali is the closest substitute. Korean red panax ginseng is another route, compared in our ginseng supplements comparison, and shilajit is a third, covered in our shilajit comparison. Buyers over 40 comparing several categories may find our guide to supplements for men over 40 useful.
How to read a fadogia label
Capsules per serving. Nutricost’s 240 capsules at one a day last eight months. Our 90 capsules at three a day last one month. Divide before you compare.
Extract ratio. 10:1 and 30:1 extracts at the same milligram figure are different products. A label with a milligram amount and no ratio can’t be compared with anything here.
Cost per 1,000 mg. Nutricost’s $24.97 bottle costs about a third as much per milligram as Double Wood’s $29.95 bottle, which the shelf price alone would never tell you.
Plant part. The rat studies used a water extract of the stem. The Vitamin Shoppe’s facts panel and our own label both name the stem, and Double Wood’s page calls its product stem extract in its FAQ. If a label doesn’t name the plant part at all, you can’t tell whether it matches the material that was studied.
What was tested. “Third-party tested” is a category, not a result. Look for identity testing against reference plant material, heavy metals and microbes, and a certificate you can open.

Does fadogia agrestis actually work?
It hasn’t been shown in people. A PubMed search in September 2026 found 10 records on fadogia and no human trials. Rat studies reported higher testosterone after a few days of dosing, and also adverse changes in testicular markers after 28 days. Rat results don’t tell you what happens in humans.
Which is better, tongkat ali or fadogia agrestis?
Tongkat ali has the stronger evidence. It has randomized human trials, including a 63-person, 4-week trial, and a 2022 meta-analysis of five trials. Fadogia has only rat studies. Fadogia alone is cheaper per day. Many people take the two together, which is what our combination does.
How long does it take for fadogia agrestis to kick in?
No human study has measured it. The rat studies measured hormone changes within 1 to 5 days, but that doesn’t tell you what to expect in people. Anyone quoting a timeline for humans is guessing.
How much fadogia agrestis should you take a day?
Follow the label on the product you buy. Label servings here range from 300 mg to 1,500mg of extract, and 600 mg of 10:1 extract is the most common. None of these is a dose tested in people. Double Wood’s directions start at 300 mg a day for the first week.
Do you need to cycle fadogia agrestis?
Some brands suggest taking breaks, but no human data shows whether cycling is needed or how long a cycle should be. Treat any cycling advice as convention, and talk to your doctor about longer use.
Where can you buy fadogia agrestis in the US?
Nutricost, Double Wood and Toniiq sell direct from their own sites, and The Vitamin Shoppe sells its own brand online and in stores. Eternal Elixir ships Tongkat Ali + Fadogia 2010mg and Tongkat Ali 200:1 2000mg across the US, with free shipping over $100.
