Tribulus Terrestris

Want support for healthy testosterone levels and drive? Tribulus is a long-time favorite, prized for its saponins, so we pin those down at 40% and add the minerals that pull real weight: zinc, which supports normal testosterone levels, magnesium for muscle function, and B6. Finished with copper and boron. Every amount is on the label, third-party tested.

Proudly made in the USA and the UK to the strictest of standards

The saponins are the prize, so we pin them down

Tribulus terrestris is one of the longest-standing plants in men's and sports supplementation, valued for its saponins. Those saponins are what people pay for, so the standardization figure is the one that matters: each serving gives 500mg of Tribulus extract standardized to 40% saponins, a high level for the compounds the plant is prized for.

40% saponins, backed by zinc, magnesium and B6

The botanical is only half the story. Each serving adds 30mg of zinc, which supports the maintenance of normal testosterone levels and normal fertility; 360mg of magnesium, which supports normal muscle function; and 10mg of vitamin B6, which supports hormonal activity. Those are genuine nutrient roles, not botanical claims, and the reason this tablet does more than a plain tribulus extract.

Complete, and screened each batch

Finished with copper, boron and black pepper extract, it's cGMP-certified with clean binders and no artificial extras. An independent lab confirms the content and screens each batch for contaminants, with every ingredient and amount printed openly on the label.
