Full Label Disclosure

Horsewood Ingredients

Quick Answer

Horsewood discloses all 7 ingredients with exact amounts, led by 1,000mg of Tongkat Ali.

Three supporting ingredients sit below typical clinical trial doses for those ingredients individually.

What sets this label apart

All seven Horsewood ingredients are disclosed with their exact milligram amounts on the label — not folded into a proprietary blend, which is a genuine transparency strength relative to many competitors in this category.

All 7 ingredients, one by one

Tongkat Ali — 1,000mg (100:1 Extract)

The formula's lead ingredient by a wide margin. A traditional Southeast Asian root studied for testosterone pathway support, stress reduction and body composition. A 2014 study of 400mg daily found measurable strength improvements over five weeks in older adults.

Epimedium (Horny Goat Weed) — 80mg

Contains icariin, which functions as a PDE5 inhibitor at the cellular level and is studied for its potential role in nitric oxide production and healthy circulation.

Saw Palmetto — 20mg

Widely researched for prostate support and healthy hormone balance. This dose is notably lower than the 160 to 320mg typically used in dedicated Saw Palmetto clinical trials.

Boron Chelate — 20mg

A trace mineral studied for its potential role in reducing SHBG, which could theoretically increase free testosterone availability. Also studied for bone density and cognitive support.

Nettle Leaf — 20mg

Traditionally included for its potential to bind SHBG and its mild anti-inflammatory properties. Generally well-tolerated with a solid safety profile.

Wild Yam — 20mg

A traditional botanical with a long history in herbal wellness, associated with hormonal balance support. Evidence at this dose is emerging rather than established.

Sarsaparilla — 20mg

Historically used in tonics for male energy and vitality. Some research suggests anti-inflammatory and antioxidant properties, though clinical evidence at this specific dose remains limited.

The dose gap worth understanding

Not all seven ingredients are dosed equally. Tongkat Ali, at 1,000mg, is the clear formula anchor. Saw Palmetto, Nettle Leaf and Wild Yam are each included at 20mg — below the 160 to 320mg range typically used in dedicated clinical trials for Saw Palmetto specifically. This doesn't mean those ingredients do nothing at 20mg, but it does mean they carry a supporting, rather than headline, role in this formula.

A note on Tongkat Ali and the EFSA review

In 2021, the European Food Safety Authority flagged a high-dose animal study (2,000mg per kilogram of body weight) as raising DNA damage concerns in stomach tissue. Horsewood's 1,000mg of 100:1 extract is a substantially different form and dose than the raw material referenced in that animal model; typical human supplementation research uses 200 to 400mg of standardized extract.

Who should be cautious

Men on blood thinners, hormone therapies or blood pressure medication should speak with their doctor before starting, given the formula's hormonal pathway activity. Not intended for men under 18.
