Horse Fuel is a chewable gummy sold for men’s energy and stamina, one a day. Every active is itemised — which is how you can see that the four botanicals it is sold for weigh 0.4 mg between them, and that one gummy carries 84% of the adult daily limit for vitamin D.

Horse Fuel is a chewable gummy supplement sold by Thehorsefuel, the U.S. stocking partner for Horse Fuel. One bottle holds thirty gummies, taken one a day. The marketing calls it a “powerful formula made for men” and promises energy, stamina and vitality. Unlike most products in this category the Supplement Facts panel itemises every active with an amount: vitamin D3 84 mcg, sodium 10 mg, boron 7 mg, and four botanical 10:1 extracts — fenugreek, maca, tribulus and horny goat weed — at 100 mcg each. That is 0.4 mg of botanical material in total. Prices show at the seller’s checkout.
If you read one more line, read this one: the four ingredients this product is sold for weigh 0.4 mg between them. That is four tenths of one milligram, in a gummy that weighs several grams. It is not an interpretation and it is not a technicality — it is the panel’s own arithmetic, and you can check it on the label page.
The second thing to know is that this label is the most transparent one this desk has covered. Every active carries its own amount. There is no proprietary blend hiding the split. That is a genuine point in its favour, and it is also precisely what lets anyone who can divide see what is in the bottle.
The third thing is the vitamin D3. At 84 mcg a gummy it is the only ingredient here present in a quantity the research would recognise, and it is 84% of the adult daily upper limit with nothing on the bottle to say so.
This is the section a retail site would not print. It is one division sum and it decides everything else on this page.
The bars are on a logarithmic scale, because a linear one would draw the product’s own bar as an invisible line. Every figure in the lower rows is a real published quantity: 257 mg is the tribulus intake the NIH Office of Dietary Supplements records as studied for safety in an 80 kg adult, and a teaspoon of maca powder is the amount named in the case report Memorial Sloan Kettering cites. Horse Fuel contains 0.1 mg of each.
A microgram is a millionth of a gram. A milligram is a thousandth. The four botanicals on this panel are listed at 100 micrograms each, which is 0.1 mg each and 0.4 mg for all four. A single grain of table salt weighs about 0.6 mg, so the entire botanical content of this gummy is smaller than one grain of salt.
The 10:1 ratio makes that worse rather than better, though it looks impressive on a label. A 10:1 extract means ten parts of raw plant were reduced to one part of concentrate. So 100 mcg of a 10:1 fenugreek extract was drawn from about 1 mg of fenugreek seed. The research on fenugreek, maca and tribulus is conducted in hundreds of milligrams and in grams — the case report Memorial Sloan Kettering cites for maca describes a teaspoon of powder a day, which is roughly three grams, or thirty thousand times what is in this gummy.
It does not mean the product is dangerous, and it does not mean the manufacturer broke a rule. Micro-dosed botanicals are legal, common, and in one respect honest: the amounts are printed, which is more than a proprietary blend does. What it means is that if you are buying this expecting the botanicals to do something, the quantities are not there to do it, and you can establish that yourself in one sum without trusting anybody — including us.
We read the bottle photographs before we wrote a word of this site, and checked every number on the panel against the FDA’s published Daily Value table. Eight things did not survive that check. A retail site would smooth these over. All eight are printed here instead, numbered, because you are about to swallow this.
Fenugreek, maca, tribulus and horny goat weed are each listed at 100 mcg. One hundred micrograms is one ten-thousandth of a gram. All four together come to 0.4 mg — less than the weight of a grain of table salt. Each is a 10:1 extract, which means 100 mcg of it was drawn from about 1 mg of the raw plant. The clinical literature on these four works in hundreds of milligrams and in grams. This is the single most important fact on the label and it is the reason this site exists.
The panel prints Tribulus Terrestris Extract 10:1 (Trigonella foenum-graecum L.). Trigonella foenum-graecum is fenugreek — it is the binomial printed two rows above, on the fenugreek line. The botanical name for tribulus is Tribulus terrestris. Either the Latin name was copied down from the wrong row, or the row is not tribulus. We cannot tell you which from a photograph, and the manufacturer has not said.
The panel prints Sodium 10 mg — <7%. The FDA Daily Value for sodium is 2,300 mg. Ten milligrams of 2,300 is 0.4%. “Less than 7%” is true in the way that “less than a million” is true, and it is not how a percent Daily Value is printed.
Vitamin D3 is listed at 84 mcg, 420% of the Daily Value. That arithmetic is correct — the DV is 20 mcg. What the bottle does not say is that 84 mcg is 5.6 times the RDA of 15 mcg and 84% of the Tolerable Upper Intake Level of 100 mcg a day that the NIH Office of Dietary Supplements sets for adults — from this one gummy, before anything else you take. The word on the label is also misspelled: cholecalciferol, not “Cholecaliferol”.
The panel prints Total Sugars 3 g and Includes Added Sugars 0. Added sugars are sugars put into a food during processing; naturally occurring sugars are the ones already in a fruit, a vegetable or milk. This is a manufactured gummy. Where three grams of non-added sugar came from is not explained anywhere on the label.
A gummy needs a gelling agent, a sweetener, an acid, a colour and usually a coating. The label photographs supplied to this desk show no Other Ingredients line anywhere. The marketing artwork pictures cane sugar, an apple and a bowl of syrup; the label names none of them. If you have an allergy, a dietary restriction or a reason to avoid gelatin, there is nothing on this bottle for you to read.
The FDA’s own labeling guide states that you “must include the part of the plant from which a dietary ingredient is derived in the ‘Supplement Facts’ panel”. Fenugreek says seed, maca says root, horny goat weed says leaf. Tribulus says nothing. Tribulus fruit and tribulus aerial parts are not the same material, and the difference matters to anyone comparing this with a study.
There is no sentence on the front label. There is a gold horse, a male symbol, and three icons: a lightning bolt, a flame and a heartbeat. The written claims — energy, stamina, vitality — appear only on the marketing panels. A claim made in a pictogram is read the same way by a buyer and is harder to hold anyone to.
Nothing except print them. We are a stocking partner, not the manufacturer, and we have no explanation to offer beyond what is on the bottle. If any of the eight matters to your decision — and findings 1, 4 and 6 should — the number to call before buying is +1 (302) 200-3480.
Every row below is on the bottle. Nothing has been added, reordered or tidied up, including the misspelling of cholecalciferol and the Latin name on the tribulus row. The full reading, line by line, is on the label page.

Four of the six products this desk has covered used a proprietary blend: one total, no individual figures, nothing to check. Horse Fuel does not. Every active has its own number beside it.
That is a real difference and it deserves saying plainly, because it is the reason this product scores 3 out of 5 for label transparency where the blend products scored 1. Transparency is not the same as adequacy. This label tells you the truth about how little is in it.
It is also why the errors matter more here. A panel that shows its working invites you to check the working, and four of the eight findings below are arithmetic or nomenclature mistakes that a proprietary blend would simply have concealed.
Everything in this table came from the bottle photographs or the seller pack we were given. Where a fact was not published, the table says so instead of guessing.

Fenugreek has a real research file and it is about blood sugar and cholesterol. Memorial Sloan Kettering’s monograph does not discuss testosterone or libido at all.
Maca is the closest fit to what this product is sold for. MSK lists improving energy and sexual desire among its purported uses and then says the evidence for sexual dysfunction has been deemed limited by systematic reviews.
Tribulus has the most direct verdict against it anywhere in this category. The NIH Office of Dietary Supplements records the proposed mechanism and then the finding: no effect on strength, lean body mass, or sex hormone levels.
Horny goat weed has the longest tradition and the thinnest modern file. MSK’s summary is one sentence: traditionally used for fatigue and sexual problems, and more studies are needed.
Read all seven in full, with the exact sentences we quoted from each source.
If any single line on this panel deserves a decision from you, it is this one — and it is not the line the marketing is about.
| Reference | Amount | In IU | One gummy is |
|---|---|---|---|
| Horse Fuel, one gummy | 84 mcg | 3,360 IU | — |
| Daily Value used on labels | 20 mcg | 800 IU | 420% |
| RDA, adult men 19-70 | 15 mcg | 600 IU | 5.6× the RDA |
| Tolerable Upper Intake Level, adults | 100 mcg | 4,000 IU | 84% of the limit |
The label’s own 420% figure is correct — that is 84 divided by the 20 mcg Daily Value. What the label does not print is the row beneath it. The NIH Office of Dietary Supplements sets the adult Tolerable Upper Intake Level at 100 mcg a day, and one gummy uses 84% of it.
A 4,000 IU vitamin D product is an ordinary thing to buy and many people who are deficient are told to take one. The problem is not the dose in isolation. The problem is that this bottle is not sold as a vitamin D product, so a buyer reaching for energy and stamina has no reason to check what else in their cupboard contains vitamin D — and multivitamins, calcium combinations, fortified drinks and cod liver oil all do.
Nothing on the label, and nothing on any marketing artwork supplied with this product, mentions the upper limit, tells you to count other sources, or warns against taking two. The NIH lists what sustained excess can do: “nausea, vomiting, muscle weakness, confusion, pain, loss of appetite, dehydration, excessive urination and thirst, and kidney stones.” Add up your vitamin D before you start.
Seven steps, all of them drawn from the directions on the bottle or from the sources we cite. Nothing here is invented, and where the label is silent we say that it is rather than choosing for you.
The label’s whole instruction is: “As a dietary supplement, take 1 gummy daily, or as directed by your healthcare provider.” There is no morning-or-evening guidance, no with-food guidance and no cycling advice, so any of those you read elsewhere came from somewhere other than this bottle.
This is the one step on this page that could matter to your health. One gummy carries 84 mcg of vitamin D3, which is 84% of the adult upper limit of 100 mcg a day. If you also take a multivitamin, a separate vitamin D, a cod liver oil or a fortified drink, add them together first. The bottle says nothing about this.
The caution is explicit: “Do not exceed recommended dose.” On a gummy that instruction does more work than on a capsule, because gummies taste like sweets and are easy to treat as such. Two gummies is 168 mcg of vitamin D, which is above the upper limit before anything else you eat.
“KEEP OUT OF THE REACH OF CHILDREN” is printed on the label and it is the single most important line on any gummy supplement. A bottle of thirty sweet chewables containing 2,520 mcg of vitamin D in total is not a thing to leave on a kitchen counter.
“DO NOT USE IF SAFETY SEAL IS DAMAGED OR MISSING.” Straightforward, and worth the two seconds.
The label says: “Keep away from heat, light, and humidity to preserve freshness.” Gummies fuse into one mass in heat and go tacky in humidity. A cupboard is right; a gym bag and a glovebox are the two worst places for them.
Thirty days is one bottle and one clean test. If something changes, the honest first hypothesis is the 84 mcg of vitamin D — especially if you were low to begin with — rather than 0.4 mg of botanical extract. Write down the boring things: sleep, session quality, mood. Be ready to conclude nothing happened.
The full how-to-use page covers what to do about a missed day, whether to take it with food, why a gummy format changes the storage question, and why we will not print a “results by week four” chart.
Most of this formula is present in quantities too small to interact with anything. The exceptions are the two nutrients and the missing ingredients list. The full detail, with the exact wording from each source, is on the safety page.
One gummy is 84 mcg, which is 84% of the 100 mcg adult upper limit. A separate vitamin D capsule, a multivitamin or a cod liver oil on top of it will take you past the limit every day without anything on either label telling you so. This is the most likely way this product causes a problem.
There is no Other Ingredients list on this label. No gelling agent, no sweetener, no colour, no coating and no allergen statement. You cannot tell whether the base is gelatin or pectin, which means you cannot tell whether it is suitable if you avoid pork or beef gelatin, and you cannot check it against an allergy. Call the order desk and ask before buying.
Memorial Sloan Kettering’s fenugreek monograph lists all three under do not take, along with cyclophosphamide and pregnancy. At 100 mcg of a 10:1 extract the exposure is around one milligram of raw seed, so the risk is almost certainly negligible — but the interaction is real at real doses and your prescriber should decide, not us.
MSK notes that maca may interfere with testosterone immunoassays. Again, the amount here is tiny. Mention it anyway if a blood panel is coming up, because an unexplained result is worth avoiding.
The label’s own caution reads: “Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18 and individuals with a known medical condition should consult a physician before using this or any dietary supplement.” It also carries the three lines every US supplement bottle carries: keep out of the reach of children, do not use if the safety seal is damaged or missing, store in a cool dry place. On a bottle of thirty sweet chewables, the first of those three is the one that matters most.
Three packs, and no prices printed on this site, because we were not given a price list — the seller’s checkout is where the live number lives. What we can tell you is how many gummies each pack contains and how long it lasts at the one-a-day the label gives.
Unusually for this category, the product photography shows the product. Thirty black chewables and the jar they come in, with nothing implied that is not there.
It is worth crediting, because the same shot in a competitor’s hands would have a kettlebell, a silhouette and a lens flare in it. What is doing the persuading on this product is elsewhere: the three icons on the front label and the four benefit lines on the marketing panel.
The gummies themselves are the part of this product you can check. Thirty of them, one a day, thirty days. That count is the only quantitative claim on the whole jar you can verify without a laboratory.

If you are asking which one to buy first: the single bottle. It is the worst value per bottle of the three and we are recommending it anyway, because thirty days is the smallest amount of money you can put at risk on a product whose four headline ingredients weigh 0.4 mg between them and whose return window length has never been published to us. The pricing page has the full reasoning and a cost sum you can finish once you can see the checkout price.
This site sells this product and earns a commission on it. A score published in that position is worth exactly as much as its reasoning, so the reasoning is printed beside every row.
The highest row is label transparency, at 3, and that is not a courtesy. An itemised panel is meaningfully better than the proprietary blends this desk has spent most of the year reading. The lowest rows are ingredient evidence, claim accuracy and safety information, all at 1, for the reasons set out above: the botanicals are present at 0.4 mg, the marketing promises what they cannot deliver, and the one ingredient that is present in quantity carries no warning about the ceiling it sits just under.
The full verdict page sets out what would change each row, and why there is no star rating anywhere on this site.
A chewable gummy dietary supplement sold for men's energy, stamina and vitality. Thirty gummies to a bottle, one a day, so one bottle is thirty days. It is distributed by Vitalifes and sold on this site by U.S. stocking partner for Horse Fuel.
Seven actives, all itemised: vitamin D3 at 84 mcg, sodium at 10 mg, boron at 7 mg, and four botanical 10:1 extracts at 100 mcg each — fenugreek seed, maca root, tribulus and horny goat weed. Plus 20 calories, 4 g of carbohydrate and 3 g of sugar.
No. One hundred micrograms is a ten-thousandth of a gram. All four botanicals together come to 0.4 mg. Because they are 10:1 extracts, each represents roughly one milligram of the raw plant. The research on these four works in hundreds of milligrams and in grams.
Nothing on the label claims that it does, and the research does not support it at any dose here. The NIH Office of Dietary Supplements, reviewing tribulus for athletic performance, records “no effect on strength, lean body mass, or sex hormone levels”. Memorial Sloan Kettering says human studies of tribulus and testosterone gave mixed results.
We do not know. Trigonella foenum-graecum is fenugreek, and it is already printed two rows above on the fenugreek line. The botanical name for tribulus is Tribulus terrestris. This is finding 2 on our list and the manufacturer has not explained it.
It is 5.6 times the RDA and 84% of the 100 mcg daily upper limit the NIH Office of Dietary Supplements sets for adults — from one gummy. That is not unusual for a standalone vitamin D product, but it is worth knowing if you also take a multivitamin or a separate vitamin D, because they stack and this bottle does not mention it.
We cannot tell you. The label photographs supplied to this site show no Other Ingredients list at all — no gelling agent, no sweetener, no colour, no coating. If you need allergen information or want to know whether the base is gelatin or pectin, there is nothing on this bottle to read.
The label says: “As a dietary supplement, take 1 gummy daily, or as directed by your healthcare provider.” One a day, thirty days to a bottle.
The live price is shown at the seller's checkout. We were not given a price list, so no pack card on this site prints a number.
A money-back satisfaction seal appears on the artwork, but no window length was supplied to us. The return procedure was: post to the returns address with your full name, email and order ID, buyer pays return shipping with tracking, refund issued 3-5 business days after the return is credited. The window length itself is whatever the marketplace listing states.
Because the review figures supplied with this product use the same star distribution and the same handful of customer sentences as every other product pack from this supplier, and one of those packs states outright that its review data is layout copy. We will not publish invented people as customers.
Thirty gummies, one a day, every active itemised — 84 mcg of vitamin D3, 7 mg of boron, and four botanicals totalling 0.4 mg. Eight label findings we have printed rather than hidden. The live price and the return terms are both shown on the seller’s checkout screen.
