Why the doses are printed instead of blended
A proprietary blend lets a manufacturer print one number for six ingredients. It is legal, it is common, and it makes any honest comparison impossible, because a blend listed at 365 mg could be 360 mg of the cheapest botanical and a dusting of everything else. Horse Boost prints each figure separately. That decision constrains us: you can hold the label next to anything else in the category and judge it on arithmetic rather than adjectives.
It also means we have to be straight about what the numbers are. 100 mg of L-arginine is a maintenance intake, not the multi-gram dose used in clinical work[4]. 50 mg of ashwagandha extract is a modest daily amount rather than the 300 to 600 mg often used in trials[2]. The formula is built as a daily background support product taken over months, and the doses are consistent with that job, not with a single-dose intervention.
Ingredient by ingredient
L-arginine, 100 mg
A conditionally essential amino acid and the direct substrate for nitric oxide synthesis. Nitric oxide relaxes vascular smooth muscle, which widens the vessel and improves blood flow[4]. It is the ingredient in this formula with the clearest and best-documented mechanism, which is why it carries the largest dose.
Maca root extract, 75 mg
Lepidium meyenii, a cruciferous root grown at altitude in Peru, eaten as a food there and used as a traditional tonic for stamina and libido. The research base is modest but real, and it is one of the better studied botanicals in the men's category[3].
Tribulus terrestris extract, 60 mg
A vine fruit standardised for steroidal saponins. Tribulus has been a fixture of men's formulas since the 1990s. The evidence is mixed and the popular claims about testosterone are not supported by the better trials[7]. It is included for the traditional drive and tone use, and we would rather say that than repeat a claim the data does not carry.
Ashwagandha root extract, 50 mg
Withania somnifera, the adaptogen with the deepest research file of the five botanicals here, studied mostly around stress response, cortisol and sleep quality[2]. It is also the ingredient behind the one recurring side effect note: vivid dreams during the first week for a minority of people.
Muira puama bark extract, 40 mg
Ptychopetalum olacoides, Amazonian bark known in traditional Brazilian practice as potency wood. The evidence is historical and preliminary rather than clinical. It is here for the traditional pairing with catuaba, and we are not going to dress that up as something else.
Catuaba bark extract, 40 mg
Erythroxylum catuaba, a Brazilian bark taken as a general tonic and almost always combined with muira puama in traditional preparations. Of the six actives this is the one with the thinnest research file.
The gummy base and allergens
Other ingredients: glucose syrup, cane sugar, pectin, citric acid, natural strawberry flavor, black carrot juice concentrate for color, fractionated coconut oil and carnauba wax. The base is pectin, not gelatin, so the gummy is suitable for vegetarians. It contains no dairy, no soy, no wheat and no tree nuts, and it is produced in a facility that also handles other supplement formats, which is worth knowing if you have a severe allergy.
Each gummy contains sugar as part of the base. If you count carbohydrates or manage blood glucose, factor it in the way you would any chewable supplement.
How to take it
One gummy a day, chewed, ideally with your first meal. Not two. Doubling the serving does not accelerate anything, and reviewers who tried it reported no difference except a faster empty bottle. Consistency is the whole mechanism with adaptogenic botanicals; a fixed daily trigger beats a higher dose every time.
