Horse Fuel Ingredients List: 7 Checks on the Supplement Facts

By the Horse Fuel Editorial Desk · Medically reviewed by Dr. Jonathan Clavell, MD, Physician · Reviewed · Last updated · how we check facts

Quick answer

Reading down the Horse Fuel Supplement Facts panel you meet seven actives: boron at 7 mg, vitamin D3 at 84 mcg, sodium at 10 mg and four plant extracts (fenugreek, maca, tribulus, horny goat weed) at 100 mcg apiece. No Other Ingredients list appears, so the gummy base and allergens are not named.

Key facts

  • Serving: 1 gummy. Servings per container: 30.
  • Per gummy: 20 calories, 4 g carbohydrate, 3 g total sugars, 0 added sugars.
  • Nutrients: vitamin D3 84 mcg (420%), sodium 10 mg, boron 7 mg.
  • Plant extracts: four at 10:1 and 100 mcg each, 0.4 mg together.
  • Label slips: the sodium percentage prints as under 7% where the sum gives 0.4%, and the tribulus row shows fenugreek’s Latin name.
  • Missing: an Other Ingredients list, an allergen statement, marker content for the extracts and a readable best-before date.

What are the 7 checks for reading the Horse Fuel ingredients list?

Take the bottle, or the back-of-bottle photograph below, and move down the panel from top to bottom. Seven stops cover everything on it.

  1. Serving size and count

    Serving size 1, servings per container 30. One gummy is one serving, so the bottle runs 30 days at the label’s one a day.

  2. Calories, carbohydrate and sugar

    20 calories, 4 g total carbohydrate (1%) and 3 g total sugars. Added sugars print as 0. On a made gummy that is unexplained, so do not call it sugar free.

  3. Vitamin D3

    84 mcg as cholecalciferol, shown as 420% of the Daily Value of 20 mcg. The sum is right: 84 divided by 20 is 4.2. The label spells the word “Cholecaliferol”.

  4. Sodium

    10 mg as sodium citrate, printed as “<7%”. The Daily Value for sodium is 2,300 mg; 10 mg works out to 0.4%.

  5. Boron

    7 mg as boron glycinate. It has no Daily Value, so the panel shows a symbol instead of a percentage.

  6. The four plant extracts

    Fenugreek seed, maca root, tribulus and horny goat weed leaf, each a 10:1 extract at 100 mcg. Read the unit first: mcg, not mg.

  7. The footnote and the blanks

    The footnote uses one symbol while the table uses another. Below the panel there is no Other Ingredients line at all.

What do the label, amounts and percentages say?

Add the four plant rows: 4 times 0.1 mg is 0.4 mg. For scale, the site notes that a single grain of table salt weighs about 0.6 mg. The whole plant-extract content of one gummy is lighter than that.

Why does the tribulus row show a different Latin name?

The row reads Tribulus Terrestris Extract 10:1, followed by the Latin name Trigonella foenum-graecum L. That second name is fenugreek, which is already printed two rows above. The botanical name for tribulus is Tribulus terrestris.

Either the name was copied from the wrong row or the row is not what it says. A photograph cannot settle which, and the maker has not explained it. The plant-part words differ too: seed for fenugreek, root for maca, leaf for horny goat weed, and nothing at all for tribulus. Tribulus fruit and tribulus above-ground parts are different material, so the missing word matters to anyone comparing the gummy with a study.

This is a fair question to ask the order desk. If you get a clear answer, send it to the site desk and the pages will be corrected.

What is missing from the Horse Fuel ingredients list?

An ingredients list for a gummy normally has two parts: the Supplement Facts panel for the actives, and an Other Ingredients line for everything else. Here only the first part is on the images supplied.

  • Gelling agent. A gummy needs one. Gelatin and pectin are the common ones, and the label names neither.
  • Sweetener, acid, colour and coating. Not named.
  • Allergen statement. None, because there is no list to hold it. The marketing art shows cane sugar, an apple and syrup, yet the label names none of them.
  • Suitability. You cannot tell if it is vegetarian, vegan, halal, kosher or allergen free from the bottle.
  • Marker content. The “10:1” ratio tells you about concentration, not about the active compounds.

If this matters to you: call the order desk on +1 (302) 200-3480 and ask whether the physical jar has an Other Ingredients list. If yours does, send a photograph to the site desk and the pages will be corrected.

What does a 10:1 extract ratio tell me?

A 10:1 label tells you roughly ten parts of raw plant stand behind each part of extract. So 100 mcg of extract points back to about 1 mg of plant. Multiply by ten and you have the raw-plant equivalent.

The ratio is real information, but it is easy to read in the wrong direction. Ten times a very small number is still small. A ratio also says how concentrated an extract is, not how active it is, and the label names no marker compound for any of the four.

For scale, the site cites a teaspoon of maca powder at about 3 g, which is 3,000 mg. That is 30,000 times the 0.1 mg of maca extract in a gummy.

What does the panel do well?

Credit belongs where it is earned. Each active has its own amount, and all four plant rows print a ratio. Three of the four also name the plant part. With a serving size of one gummy, there is no dosing sum to get wrong.

That is why the editorial score for label transparency is 3 out of 5, the highest the desk has given. The same openness is what lets you see how small the plant amounts are. A hidden blend would have shown you nothing.

Two things can both be true

An honest label and a small formula are not opposites. The panel is clear about a small amount, and the clarity is a point in its favour.

Frequently asked questions

What is in Horse Fuel?

Seven itemised actives. The nutrients are vitamin D3 at 84 mcg, boron at 7 mg and sodium at 10 mg. The plants are fenugreek, maca, tribulus and horny goat weed at 100 mcg apiece. Each gummy also has 20 calories, 4 g carbohydrate and 3 g sugars.

Does Horse Fuel have an Other Ingredients list?

Not on the images supplied. That means the gummy base, sweetener, colour, coating and allergens are not named.

Is Horse Fuel vegetarian or vegan?

It cannot be told from the bottle. The label does not say whether the base is gelatin or pectin.

How much of each plant extract is in a gummy?

100 mcg of each of the four. Converted, that is 0.1 mg per extract and 0.4 mg for the set. All four are 10:1 extracts.

Why does the tribulus row show Trigonella foenum-graecum?

That is the Latin name for fenugreek. The maker has not explained why it is printed on the tribulus row.

Is the sodium percentage on the label correct?

No. The panel prints under 7%, yet 10 mg divided by the 2,300 mg Daily Value is about 0.4%.

Our view

Our view is that this is a short, honestly itemised ingredients list with a few clear slips. The wrong sodium percentage and the odd Latin name do not change what is in the gummy, but they tell you how carefully the artwork was proofed.

Use the seven checks on your own bottle, and bring any difference to us. Your bottle beats our page. If you have an allergy or a dietary rule, ask the order desk about the missing list before you buy, and talk to your doctor about vitamin D if you already take it.
