Tribulus terrestris extract

Tribulus terrestris extract (CAS 90131-68-3, EC 290-381-1) is a standardised plant extract derived from the fruit, root, or aerial parts of Tribulus terrestris, concentrated primarily for its steroidal saponin content, particularly protodioscin. It carries no assigned E-code and is commonly referenced as Tribulus Extract or TribulusTerrestrisExtract in supplier documentation.

In food supplement and nutraceutical formulations, the extract is incorporated into capsules and tablets targeting sports nutrition and male health categories, where saponins are understood to support hormonal balance pathways. In topical personal care applications, its antioxidant activity helps neutralise free radicals, contributing to oxidative stability in finished formulations.

Tribulus terrestris extract is available in powder form at varying saponin standardisation levels, typically 40–90% by UV assay. Suppliers operating within the EU must comply with REACH registration obligations and applicable novel food regulations. Packaging is generally offered in fibre drums or double-lined polyethylene bags.
