Tribulus Terrestris
Used in various traditional systems, Tribulus is often included in supplements designed to support physical performance and muscle tone. It works by supporting the body's own regulatory systems — a favorite among those who prefer plant-based support for their fitness goals.
Sourcing matters: look for extracts standardized to saponin content, which reflects the concentration of the active plant compounds. Avoid products that list only the raw plant weight without extract ratio information.
