Specification strategy
What buyers should specify before comparing Tribulus Extract.
Tribulus Extract grades can differ in marker profile, extract ratio, carrier system, colour, sensory profile and physical powder behaviour. These variables should be confirmed against the exact commercial specification.
For this ingredient, commercial specifications may be differentiated by steroidal saponins / protodioscin where specified where specified. NutriCo does not assume every available grade uses the same target; the current specification should be used for confirmation.
Botanical Identity & StandardisationTribulus terrestris fruit / aerial part, depending on grade extract. Standardisation options are defined according to the selected commercial specification, including steroidal saponins / protodioscin where specified where relevant.
Extraction & Carrier SystemPressurised aqueous extraction with spray-dried powder format. Extract ratio and carrier system are defined according to the selected commercial grade.
Physical CharacteristicsFine powder, typically light brown / tan, with characteristic botanical odour and taste. Moisture, bulk density and flow parameters are controlled according to specification.
Contaminant & Microbiological ControlControlled for microbiological criteria, pesticide residues and heavy metals where applicable. Batch-specific analytical values are reported on the Certificate of Analysis.
