Tribestan properties and applications

Further R&D efforts included incorporation in a tablet form of a substance greatly affected by absorbed humidity. Tribestan was approved for production and implemented in mainstream practice in 1985, and on the market ever since. The product is practically non-toxic and has no side effects - no changes of lifestyle required. Tribestan is natural and safe based on a proprietary extract from Sopharma and the active substance does not contain herbal particles.

We would like to emphasize that the push towards higher Protodioscin content in Tribulus based products is misleading. The product claiming higher levels of Protodioscin simply use inferior extracts or ground herbal material and artificially add Protodioscin. The true superiority of the effectiveness and safety of Tribestan is expressed in a biologically balanced substance where are present not only Protodioscin, Protogracillin, but other key saponins in critically important ratios.

Tribestan's safety

  • Special attention should be given to the harmlessness of the natural herbal product Tribestan.
  • No evidence of acute, sub-acute and chronic toxicity has been found during the experimental behavioral, hematological, functional, biochemical and morphological studies.
  • Absence of carcinogenic and teratogenic effect.
  • No adverse effects were noted in any of the clinical studies and additional research demonstrated no adverse effects.

Gift of Nature to Humanity!

Margarita Tomova Pharm D. Head of Tribestan development team

Tribestan is a natural product and is obtained from the thorn plant Tribulus Terrestris L., growing in Bulgaria. The natural habitats of the plant have been extensively studied and are well defined as species and like other plants, would often change its composition depending on the site and conditions of growth. Tribestan has well defined chemical composition and is standardized in relation to its active ingredients. The author and the product development team took very active part in its implementation in regular production by the manufacturer Sopharma AD of Sofia, Bulgaria. Curiously enough, the development of this product cost nearly 20 years to the principal author and the research team, as the active ingredients turned out to constitute a new type of active substances. Thus, an author's hypothesis, connected with the long-lived experience was finally crowned with success and got its modern tune and meaning.
