Purity, down to the details

Heavy metals, pesticides and herbicides: what we watch for, which limits apply, and how we deliver on it. Plus a fresh FAQ.

Our standards and values

European legislation sets clear upper limits. For us that is are the floor, not the goal: where reasonably possible, we aim lower (the ALARA principle, Reg. (EC) 315/93).

1 · Our standards for heavy metals

Lead, cadmium, mercury and arsenic can end up naturally in soil and plants. Because some can accumulate in the body, we test every finished product against the statutory maxima for food supplements from Reg. (EU) 2023/915 — with margin to spare.

Heavy metalLegal maximum — food supplements
Lead (Pb)3.0 mg/kg
Cadmium (Cd)1.0 mg/kg*
Mercury (Hg)0.10 mg/kg
Inorganic arsenic (As)≤ 3 mg/kg**

*3.0 mg/kg for supplements consisting mainly of dried seaweed or bivalve molluscs. For arsenic there is no separate supplement limit; the purity criteria for added substances (Reg. (EU) 231/2012) use up to 3 mg/kg as the upper limit. We structurally aim lower.

2 · Our standards for pesticides

For plant protection products, European maximum residue levels (MRLs) apply per substance and per crop, laid down in Reg. (EC) 396/2005 and the EU pesticides database. Where no specific MRL exists for a substance, the strictest standard applies: the default limit of 0.01 mg/kg. Analyses are carried out in accredited labs with LC-MS/MS and GC-MS/MS, down to ppb level (billionths).

3 · Our standards for herbicides

Herbicides — including glyphosate — fall under the same MRL system of Reg. (EC) 396/2005. Here too: a crop-specific MRL where one exists, and otherwise the default limit of 0.01 mg/kg. Our starting point remains the precautionary principle — where there is reasonable doubt we do not wait for a ban.
