Horse Boost uses six ingredients that are common in the men's supplement aisle, at everyday doses, made in an FDA-registered and GMP-certified facility. That said, safe in general is not the same as safe for you. If you take blood pressure medication, nitrates, blood thinners, thyroid medication or antidepressants, or if you are scheduled for surgery, ask your doctor before starting. Horse Boost is for adult men only.

Does Horse Boost have side effects?

Most men report none. The reports we do receive are mild and short: a little stomach heaviness when the gummy is chewed on an empty stomach, and occasionally vivid dreams in the first week, which is a known effect of ashwagandha for some people. Because the gummy contains sugar, men managing blood glucose should count it. Stop and speak to a clinician if anything unusual persists.

Is Horse Boost FDA approved?

No, and neither is any other dietary supplement. The FDA does not approve supplements the way it approves drugs. What can be said accurately is that Horse Boost is manufactured in an FDA-registered facility that follows current Good Manufacturing Practice rules, and that the statements on this site have not been evaluated by the FDA. Horse Boost is not intended to diagnose, treat, cure or prevent any disease.

The formula

What is inside a Horse Boost gummy

Written by the Horse Boost formulation team. Reviewed for accuracy by Tessa Lindqvist, MS, RDN. Last reviewed July 2026. This page is an educational description of our own label, not medical advice or medical supervision.

In brief

One Horse Boost gummy carries six actives: L-arginine 100 mg, maca 75 mg, tribulus terrestris 60 mg, ashwagandha 50 mg, muira puama 40 mg and catuaba 40 mg. Arginine feeds the nitric oxide pathway behind healthy blood flow, ashwagandha and maca work on the stress and stamina side, and the three traditional barks and fruits round out a men's formula that has been sold in capsule form for decades. Every number is printed. Nothing sits behind the words proprietary blend.

The label, exactly as it appears on the bottle

A supplement facts panel is the one part of a supplement website a copywriter cannot write. Here is ours. One gummy is the serving, thirty gummies fill a bottle, and the six actives below are what you are paying for. The sugar is real and small at three grams, which is the price of making a botanical blend chewable.

Daily Value is not established for any of the six actives, which is normal for botanicals and for arginine. That is what the dagger means, and any brand printing a percentage next to ashwagandha is inventing it.

Why we do not use a proprietary blend

A proprietary blend lets a brand list six impressive names under one total weight, so nobody can tell whether the tribulus is 60 mg or 6 mg. It is legal and it is common in men's formulas. Horse Boost prints six separate numbers, so you can compare us line by line, and so we cannot quietly cut a dose between production runs without you noticing.

Pillar one: circulation and the nitric oxide pathway

The first job of the Horse Boost formula is circulatory support, and the ingredient doing that work is L-arginine at 100 mg per gummy. Arginine is a conditionally essential amino acid, which means your body makes some but demand can outrun supply. Its relevant trick is that enzymes convert arginine into nitric oxide, a short-lived gas that tells the smooth muscle lining your blood vessels to relax. Relaxed vessels widen, and wider vessels move more blood to muscle and tissue. That single pathway sits underneath a great deal of what men call vitality [4].

Be sensible about the size of the effect. A 100 mg dose in a gummy is a daily contribution, not a clinical intervention, and federal reference material on supplements for performance is deliberately measured about amino acids of this class [1]. We would rather you read that page than our marketing.

Pillar two: stress, stamina and the adaptogens

The second job is the one most men underestimate. Energy is rarely a fuel problem, it is usually a stress and recovery problem, and that is where ashwagandha earns its 50 mg. Withania somnifera is the most researched herb in this formula, with a body of work on stress, sleep quality and exercise recovery summarised by the National Center for Complementary and Integrative Health, which is candid about both the promising results and the limits of the studies [2].

Maca sits next to it at 75 mg. The Peruvian root has been eaten as food in the Andes for centuries and studied for libido, mood and stamina since the 1990s; the independent research summary is positive on the libido question and cautious on almost everything else, which is roughly how we describe it too [3]. Neither of these is a stimulant. Nothing in Horse Boost will keep you awake, and nothing in it will crash you at three in the afternoon.

Pillar three: the traditional men's botanicals

Tribulus terrestris at 60 mg, muira puama at 40 mg and catuaba at 40 mg are the traditional layer of the formula. Tribulus has been a fixture of men's supplements for forty years, mostly on the strength of animal work and a genuine history of use; the honest independent read is that human evidence for testosterone effects is weak while the libido literature is more interesting [6]. Muira puama, known in Brazil as potency wood, and catuaba bark come from the same Amazonian tradition, with centuries of use as tonics and a thin modern research file.

We include them because the traditional men's formula is what customers are looking for, we dose them where the tradition doses them, and we tell you plainly that the science behind these three is lighter than the science behind arginine and ashwagandha. A brand that treats all six ingredients as equally proven is a brand that has not read the literature [3].

What a fair dose looks like in a gummy

Gummies face a physical ceiling that capsules do not. A gummy is mostly pectin, sugar and water by weight, so the active payload has to fit in what remains without turning the texture to grit or the taste to bark. Horse Boost carries 365 mg of actives per gummy, which is an honest amount for the format.

If you want gram-level doses of a single ingredient, buy that ingredient on its own and take four capsules a day. Horse Boost exists for the man who will not do that, and who has quietly stopped taking the capsules already in his cupboard.

Quality standards behind the gummy

Horse Boost is produced by a U.S. contract manufacturer registered with the FDA and audited against current Good Manufacturing Practice. Raw materials arrive with certificates of analysis and are identity tested before production, and finished runs are tested for potency and the usual contaminant panel before release. Bottles are sealed, coded and held in a climate-controlled warehouse in Ohio, and we ship from it ourselves. General guidance on using supplements sensibly is worth reading before you buy from anyone, including us [3][7].

What Horse Boost does not claim

Horse Boost supports normal vitality, daily energy and healthy blood flow in men. It does not treat erectile dysfunction, raise testosterone to a clinical target or cure fatigue, and it is not a substitute for medication. Supplements in the United States are regulated as food, not drugs, and none is FDA approved to treat a disease [8]. If your energy or sex drive has changed suddenly, that is a conversation for a doctor, not a gummy.

A short glossary

Nitric oxide: A gas your body produces from arginine that signals blood vessels to relax and widen.
Adaptogen: A traditional category of plants, ashwagandha among them, associated with the body's response to stress.
Proprietary blend: A label device that shows the total weight of several ingredients without revealing how much of each is present.
cGMP: Current Good Manufacturing Practice, the federal quality rules a supplement facility is audited against.
Certificate of analysis: The lab document that accompanies a raw material and states its identity and purity.
Pectin base: The fruit-derived gelling agent that makes a gummy chewable without gelatin, so the product suits vegetarians.
Daily Value: The reference intake used on nutrition labels. Botanicals rarely have one, hence the dagger symbol.

Formula questions, answered plainly

The gummy base is glucose syrup, cane sugar, pectin, citric acid, natural strawberry flavor, black carrot juice for color, fractionated coconut oil and carnauba wax.
