Horsewood's label lists seven ingredients with exact doses — no unnamed proprietary blend. Here's what each one is, in plain language, along with where the research support is strongest and where it's more limited.
Saw Palmetto (Serenoa repens) Berry Extract — 20 mg
Saw Palmetto is a berry extract long used in men's health formulations, most commonly associated with prostate-related comfort and hormonal wellness support. It's one of the more widely studied botanicals in this ingredient list, though most of that research centers on urinary comfort rather than performance.
Wild Yam (Dioscorea villosa) Root Extract — 20 mg
Wild Yam is a root traditionally used to support energy and recovery. Its inclusion here leans more on traditional use than a large modern clinical trial base, and it's typically paired with other botanicals rather than used on its own.
Sarsaparilla (Smilax ornata) Root Extract — 20 mg
Sarsaparilla root has a long history of traditional use for stamina and resilience. Like Wild Yam, its modern research base is comparatively small, and it's included here as part of a broader formulation rather than as a standalone active ingredient.
Nettle (Urtica dioica) Leaf Extract — 20 mg
Nettle Leaf is frequently paired with Saw Palmetto in men's wellness formulas, with interest centered on hormonal wellness support. The two are often combined because their traditional use cases overlap.
Boron Amino Acid Chelate — 20 mg
Boron is a trace mineral that's drawn genuine research interest for its role in hormonal wellness pathways, including testosterone-related metabolism. It's one of the more mineral-grounded ingredients in the formula, as opposed to a purely traditional botanical.
Tongkat Ali (Eurycoma Longifolia) — 10 mg (100:1 extract)
Tongkat Ali is a root from Southeast Asia and arguably the best-known ingredient in this formula, with a growing body of research interest around stamina, energy and testosterone-related wellness support. The 10 mg dose here comes from a concentrated 100:1 extract, equivalent to roughly 1,000 mg of dry Tongkat Ali powder — a meaningfully concentrated dose for this category.
Horny Goat Weed (Epimedium sagittatum) — 8 mg (10:1 extract)
Horny Goat Weed contains icariin, a flavonoid compound that's been a subject of ongoing research interest for its potential role in supporting healthy blood flow and circulation. Because it can affect circulation, it's the ingredient behind Horsewood's medication interaction warning for men on blood thinners, nitrates or blood pressure medication.
A note on the evidence
Being honest about a formula means being honest about the gaps. Saw Palmetto and Boron have the more established research bases in this list; Wild Yam and Sarsaparilla lean more heavily on traditional use. Tongkat Ali and Horny Goat Weed sit in between — genuine subjects of ongoing research interest, without the decades-deep clinical trial record of a pharmaceutical ingredient. None of this formula is positioned as a cure or treatment for any diagnosed condition, and it shouldn't be evaluated as one.
