HorseFil Ingredients: Full Label Breakdown

Seven active ingredients, each with its own published milligram amount. That structure is unusual in this category and it's the main reason this label is worth taking seriously.

Tongkat Ali — 200 mg

Eurycoma longifolia, a Southeast Asian root. The largest single amount here and the ingredient with the deepest human research base on this label — trials have examined stress hormones, mood and male wellness markers.

What the research supports is modest and real. What it doesn't support is the dramatic marketing this ingredient attracts elsewhere. Full detail in our Tongkat Ali guide.

Horny Goat Weed — 100 mg

Epimedium sagittatum, supplying icariin. Long traditional use in Chinese herbal medicine, and the second-largest dose here. Also the ingredient most responsible for this formula's interaction profile — see the icariin guide.

Beet Root — 50 mg

Beta vulgaris, listed separately from the other botanicals on the panel. Beet root's mechanism is one of the better-understood in sports nutrition: dietary nitrates convert to nitrite and then toward nitric oxide, supporting vasodilation.

Dose context matters. Beetroot nitrate research typically uses concentrated juice shots delivering far more nitrate than 50 mg of extract would. It's a legitimate ingredient at a supportive rather than research-level amount.

Grape Seed Extract — 50 mg

Vitis vinifera, included for proanthocyanidins. Antioxidant activity and vascular health are where the research interest sits. A supporting ingredient rather than a driver.

Ashwagandha

The formula's adaptogen and, alongside Tongkat Ali, the ingredient with the strongest human evidence here — particularly around cortisol and perceived stress in controlled trials.

Two considerations worth raising with a doctor: ashwagandha can affect thyroid hormone levels, and it may stimulate immune activity, which matters for anyone with an autoimmune condition. See the ashwagandha guide.

Maca Root

A Peruvian root crop grown at high altitude, with long traditional use for energy and stamina and a growing modern research base around general wellbeing and mood.

L-Arginine HCl

An amino acid and direct substrate for nitric oxide synthase — the enzyme producing nitric oxide. Well-understood physiology.

Honest dose note: arginine trials generally use doses measured in grams. Whatever amount sits on this panel, it's working alongside beet root nitrates rather than carrying the circulation claim alone. Covered in the nitric oxide guide.

Ranking Them By Evidence

Sorted by weight of human research for what they're being sold for:

1. Ashwagandha — substantial human trials on cortisol and stress
2. Tongkat Ali — real human research on hormonal wellness markers
3. Beet root / L-Arginine — well-understood mechanism, dose here below research levels
4. Grape seed extract — genuine antioxidant research, indirect relevance
5. Maca root — growing evidence, mostly on wellbeing rather than performance
6. Horny goat weed — long traditional use, thinner modern human evidence

That's not a reason to dismiss the formula. It's a reason to set expectations at the top of that list rather than the bottom.

Bottom Line

A transparent label with two genuinely well-researched ingredients at its core, several supporting botanicals at modest doses, and the significant advantage that you can check every number yourself. See how these fit together.
