View details →A standardised extract is one assayed and adjusted to contain a defined percentage of an active marker compound — for example, 20% bacosides in a Bacopa extract or 95% curcuminoids in curcumin. Standardisation is what lets a formulator design a dose and make a label claim with confidence.
CTA standardises extracts using the method appropriate to each marker — HPLC, UV spectrophotometry, GC, gravimetry or titration — and confirms the result on every batch's Certificate of Analysis.
