Technical & procurement detail
What Milk Thistle Extract (Silymarin) is and what it does+
Milk thistle extract is produced from Silybum marianum seed and standardised on silymarin, a complex of flavonolignans including silybin A and B. It is poorly water-soluble, and silymarin values differ depending on whether UV or HPLC methodology is used.
UV and HPLC silymarin figures are not comparable+
A UV-reported 80% and an HPLC-reported 80% describe different material. Fix the method in your specification, and ask for the silybin content separately where it matters to your claim.
Documentation and specification+
Assay, particle size, solvent residue, microbiological limits and heavy-metal limits differ between producers and grades. Allzone confirms the applicable specification with the supplier before quoting and shares the technical data sheet, safety data sheet and certificate of analysis for the exact material offered, so the values you evaluate are the values you receive.
