Horse Boost contains six ingredients: L-Arginine, Ashwagandha, Maca Root, Catuaba Bark, Muira Puama and Tribulus Terrestris, in a natural strawberry gummy base.
Below is every ingredient in the formula, what it is, and what it is genuinely studied for. Where the support is traditional rather than clinical, this page says so — including for the ingredient the wider category most often oversells.
A semi-essential amino acid and the direct substrate for nitric oxide.
Your body converts L-Arginine into nitric oxide through the enzyme nitric oxide synthase. Nitric oxide tells the smooth muscle lining your blood vessels to relax, which widens the vessel and improves blood flow — the mechanism behind the 1998 Nobel Prize in Physiology or Medicine. This is the most mechanistically well-established ingredient in the formula, and the one with the clearest relevance to circulation, exercise performance and cardiovascular wellness.
An adaptogenic herb central to Ayurvedic practice for over two millennia.
Ashwagandha is among the best-studied adaptogens in the supplement world, examined in randomised controlled trials for the body's response to everyday stress, sleep quality and perceived energy. It earns its place here for a practical reason: chronic stress load is one of the largest real-world drains on a working man's energy, drive and recovery, and it is one of the few such inputs a botanical can plausibly influence.
A cruciferous root cultivated above 4,000 metres in the Peruvian Andes.
Maca has been grown and eaten in the high Andes for centuries, valued specifically for supporting energy and physical endurance in a punishing environment. Modern interest centres on its glucosinolates and macamides. The research base is early-stage rather than definitive, and this page treats it as promising traditional use rather than settled science.
A traditional Brazilian botanical from the Erythroxylum family.
Catuaba is one of the most widely used herbal tonics in Brazil, traditionally taken to support energy, vitality and general well-being. Its evidence base is traditional and preclinical. It sits in the formula as a stamina-side complement to Maca rather than as a headline actor.
Known in the Amazon as “potency wood”.
Muira Puama has a long record in Amazonian herbal practice for supporting men's vitality and vigour, and it remains a common inclusion in men's wellness formulas for that reason. Being straight about the evidence: human clinical data is limited, and its inclusion rests primarily on traditional use.
A flowering plant used in both Ayurvedic and traditional Chinese practice.
Tribulus is a staple of men's health formulas and is frequently marketed as a testosterone booster. That specific claim deserves scepticism: human trials in men with normal baseline testosterone have generally not demonstrated meaningful hormonal change. Its traditional use for vitality and strength is real; the hormonal marketing around it usually outruns the data. If you suspect low testosterone, ask your doctor for a blood test rather than relying on a supplement.
Each bottle holds 30 natural strawberry gummies. Chew the daily serving printed on your bottle. Always read the current label before use — manufacturers can revise a formula, a gummy base or a serving size between production runs, and the label in your hand always overrides any website.
