HorseFil Ingredients: The Six Named Ingredients Explained
Quick answer
HorseFil names six ingredients: L-citrulline, L-carnitine, Panax ginseng extract, maca root extract, rhodiola extract and grape seed extract. The amount of each is not published, so you cannot compare it with research doses. Research on these ingredients is mixed and often small. Read the Supplement Facts panel on your bottle for the full list.
What are the six named HorseFil ingredients?
HorseFil lists six named ingredients on its "Inside HorseFil" product image. They are two amino acid compounds and four plant extracts. Each gummy is a chewable, plum-colored piece, and each bottle holds 30 of them.
The image is the only public source for these names. The seller pack itself says no ingredients are named on the sales page it checked, so the image and your bottle's label are what count.
- L-citrulline
- L-carnitine
- Panax ginseng
- Maca root
- Rhodiola
- Grape seed
What does the HorseFil formula leave unpublished?
The biggest gap is dose. HorseFil does not publish how much of each ingredient sits in a serving, so no one can match it to a study.
That matters because research results depend on amount. A small sprinkle of an ingredient may act very differently from the grams used in a trial.
What does research say about each HorseFil ingredient?
Below, each ingredient gets a plain summary, the research context and the amounts studies used. Research doses are for context only. They are not HorseFil's dose.
L-citrulline
L-citrulline is an amino acid. Your body turns it into arginine, which it then uses to make nitric oxide, a signal that relaxes blood vessels.
Exercise studies have mostly looked at performance. A 2022 meta-analysis found no clear benefit for aerobic performance (Viribay et al., 2022). Up to 6 g a day showed no adverse effects in short studies (NIH ODS).
| Question | Answer |
|---|---|
| Research amounts | About 3-9 g in exercise studies. (NIH ODS) |
| HorseFil amount | Not published |
L-carnitine
L-carnitine helps carry fatty acids into the mitochondria, where cells burn them for energy. Healthy bodies make enough of it on their own.
Exercise results are mixed. About 3 g a day can cause nausea, diarrhea and a "fishy" body odor. Gut bacteria also turn carnitine into a compound called TMAO (NIH ODS).
| Question | Answer |
|---|---|
| Research amounts | 0.25-6 g a day, most often 1-3 g. (NIH ODS) |
| HorseFil amount | Not published |
Panax ginseng extract
Panax ginseng, also called Asian ginseng, is a root used in traditional medicine. It is studied for fatigue and general well-being.
It may have a small effect on general fatigue, but results are inconsistent. Short-term use up to 6 months appears safe, and trouble sleeping is the most common side effect (NCCIH, 2025). The NIH found no effect on power or endurance (NIH ODS).
| Question | Answer |
|---|---|
| Research amounts | Varies by extract. (NCCIH, 2025) |
| HorseFil amount | Not published |
Maca root extract
Maca is a Peruvian root vegetable, Lepidium meyenii. People study it for energy, mood and libido.
A 2010 review found too little good evidence on sexual function (Shin et al., 2010). A 2025 meta-analysis found performance benefits mostly in animals, with only 4 human studies (Jorquera-Aguilera et al., 2025).
| Question | Answer |
|---|---|
| Research amounts | Varies; human trials are few and small. (Jorquera-Aguilera et al., 2025) |
| HorseFil amount | Not published |
Rhodiola extract
Rhodiola rosea is an herb that grows in cold regions. It is studied for fatigue and stress.
There is not enough reliable evidence to support any use yet. It is possibly safe for up to 12 weeks. Reported side effects include dizziness, headache, trouble sleeping and dry mouth (NCCIH, 2025).
| Question | Answer |
|---|---|
| Research amounts | Varies by extract. (NCCIH, 2025) |
| HorseFil amount | Not published |
Grape seed extract
Grape seed extract is rich in plant compounds called proanthocyanidins. It is often described as an antioxidant extract.
It may modestly help LDL cholesterol and the lower number in a blood pressure reading. It is generally well tolerated, but little is known about use in pregnancy (NCCIH, 2025).
| Question | Answer |
|---|---|
| Research amounts | Varies; generally well tolerated. (NCCIH, 2025) |
| HorseFil amount | Not published |

Why does HorseFil combine these ingredients?
The mix covers a few common themes in men's vitality products. Each group aims at a different part of daily energy.
The how HorseFil works guide walks through each group in more depth.
No study of the finished HorseFil formula is published. The theme of each group is a design idea, not a tested result.
Which HorseFil ingredients need care with medicines?
Two named ingredients have known medicine concerns. Ginseng may lower blood sugar and affect clotting, and rhodiola has a reported interaction with losartan.
Talk to a doctor first if you take blood thinners, blood pressure medicine or diabetes medicine. The HorseFil side effects page covers each concern in full.
Where can you see the full HorseFil ingredient list?
