The words Tribulus terrestris on a label are not enough to compare finished products. A useful comparison begins with the exact specification.
Current Tribestan specification
Current official product information describes one film-coated tablet as containing 250 mg of dry extract from the aerial parts of Tribulus terrestris L.. It also states that furostanol saponins are not less than 112.5 mg per tablet.
What standardization tells you
Standardization gives a reader more useful information than a broad botanical label. It helps answer whether a finished product is based on a defined extract rather than an unspecified quantity of powdered herb.
Questions to ask when comparing products
- Which part of the plant is used?
- Is the product a powder or an extract?
- How much extract is present per tablet or capsule?
- Which compounds are standardized?
- Who manufactures the finished product?
- Is the product supplied with clear documentation?
