Reviewer notes
Partial report: Light Labs (ISO 17025) results page, heavy metals last tested 28 Nov 2025: arsenic 7, cadmium <0.01, lead <0.1 and mercury <0.01 micrograms; the page does not say whether this is per serving, and no batch number is shown. Fish (marine) collagen typically carries more arsenic, mostly in organic forms, but the page does not split it. Glyphosate not detected (20 Apr 2026). UK seller.
