HorseFil Ingredients: The Six Named Ingredients Explained

What ingredients are in HorseFil?

The brand's ingredients panel names six: L-Citrulline, L-Carnitine, Panax Ginseng Extract, Maca Root Extract, Rhodiola Extract and Grape Seed Extract. The amount of each one is not published. The panel is headed "INSIDE HORSEFIL" and reads "30 GUMMIES | SIX NAMED INGREDIENTS | DIETARY SUPPLEMENT".

That panel is a marketing image, not the legal label. We did not get the Supplement Facts panel, and it is not readable on the jar photos we have. So we can tell you what each ingredient is and what research has looked at. We cannot tell you how much of it sits in a gummy.

Two amino acids lead the list. Two root extracts follow. Then come a plant extract and a seed extract. Below, each one gets its own short profile.

The six named ingredients, one by one

Each profile covers three things: what the ingredient is, what research has looked at, and how the studied amount compares with what we know about HorseFil. The last part is short for every ingredient, because the amount is not published.

1. L-Citrulline

L-citrulline is an amino acid. Watermelon is a well-known food source. The body turns it into L-arginine, which it then uses to make nitric oxide.

Most human research on it is about exercise. A 2020 review found those studies commonly used about 3 to 6 g of L-citrulline a day, or about 8 g of citrulline malate (Gonzalez & Trexler, 2020). Results across the studies were not all the same.

In HorseFil: amount not published. Research used grams, not milligrams.

2. L-Carnitine

L-carnitine is a compound your body makes on its own. It helps move fats into cells, where they can be used for energy. Red meat and dairy also supply it.

The NIH Office of Dietary Supplements says studies of clinical benefit typically used 1 to 4 g a day. It also says results for exercise are mixed (NIH ODS, 2023).

In HorseFil: amount not published. Like citrulline, research amounts are in grams.

3. Panax Ginseng Extract

Panax ginseng is also called Asian ginseng. The root has a long history in traditional Chinese and Korean practice. An extract is a concentrated form of the root.

NCCIH describes the research as mixed. Ginseng may modestly help with fatigue. It does not appear to help with sport or exercise results (NCCIH, 2025). Short-term use of up to 6 months appears safe for most people.

In HorseFil: amount and extract strength not published.

4. Maca Root Extract

Maca is a root vegetable. It grows high in the Andes of Peru, where people have eaten it as food for a long time.

A 2012 review of maca looked at its traditional use and the human studies so far. It noted that those studies commonly used about 1.5 to 3 g of dried maca a day (Gonzales, 2012).

In HorseFil: amount not published. An extract can be stronger than dried root, so the label would need to say which form and how much.

5. Rhodiola Extract

Rhodiola rosea is a plant that grows in cold places. It has a history in Scandinavian and Russian herbal practice.

NCCIH says there is not enough reliable evidence to show rhodiola helps with any health purpose (NCCIH, 2025). A systematic review found the trials were of mixed quality (Hung et al., 2011). NCCIH lists it as possibly safe for up to 12 weeks.

In HorseFil: amount not published.

6. Grape Seed Extract

Grape seed extract is made from the seeds of wine grapes. It is rich in plant compounds called proanthocyanidins.

A 2016 meta-analysis pooled 16 trials on blood pressure. Those trials used amounts from the low hundreds of milligrams up to 2,000 mg a day (Zhang et al., 2016). NCCIH says it is generally well tolerated (NCCIH).

In HorseFil: amount not published.

Could one gummy hold research-level amounts?

For L-citrulline and L-carnitine, it is very unlikely. Research used 3 to 6 g of citrulline and 1 to 4 g of carnitine a day, and a single gummy is small and mostly gummy base.

A gummy has to hold sugar or sweetener, a gelling agent, flavor and color. That leaves limited room for active ingredients. Six of them share whatever room is left. We cannot confirm the real amounts without the label panel, so treat this as a reasoned estimate, not a finding.

Our page on how HorseFil works explains what that means for what you can expect.

What to check on your own jar label

Your jar should carry a Supplement Facts panel. It answers most of the open questions on this page in under a minute.

If the panel lists a "proprietary blend", you will see one total weight for several ingredients. You will not see how that total splits. That is legal, but it tells you less.

Our step-by-step guide on how to read a men's supplement label walks through each line.

Are any of the six a concern with medicine?

Some of them can be. If you take any prescription medicine, talk to your doctor before you start HorseFil.

The side effects page covers what each ingredient can cause and when to stop.

How the six ingredients group together

They fall into three loose groups. Seeing them this way makes the list easier to follow.

None of these groups adds up to a promise. The label line on the jar reads "Support for your energy, vitality & performance*". The asterisk points to the FDA statement: these claims have not been evaluated by the FDA. For what the brand says the gummies are made for, see HorseFil benefits.
