2022 heavy metal test results

Please see the most recent 2024 test results here.

Well it's been a couple of years since our last heavy metal tests were carried out, and lately we've been contacted by a number of people eager to see more recent results. We have therefore had our latest batches tested, with the results having just come in this week!


Excitingly, we have also had our organic whey protein isolate tested for the first time. So we have a double whammy. Without further ado, here are the results for both our original organic whey protein (a concentrate) and our organic whey protein isolate:

Original organic whey protein (concentrate)

Heavy metals Lab Results EU Limit
Lead <0.0050 mg/kg 3.0 mg/kg
Arsenic 0.006 mg/kg No defined limit
Cadmium <0.0010 mg/kg 1.0 mg/kg
Mercury <0.0010 mg/kg 0.1 mg/kg

Organic whey protein isolate

Lead <0.0050 mg/kg 3.0 mg/kg
Arsenic 0.024 mg/kg No defined limit
Cadmium <0.0010 mg/kg 1.0 mg/kg
Mercury 0.0010 mg/kg 0.1 mg/kg

Where there is a "<" preceding the result, there was none detected and the number shown next to the "<" is the lowest level the lab is able to test for.  So it doesn't mean that there isn't any, it just wasn't found for that testing limit. Regardless, all of the results are significantly lower than for EU limits, where EU limits exist - for arsenic you can see there are no EU limits.


As usual, we are unable to find any other whey proteins on the market with lower heavy metal levels.  And as a reminder, heavy metals are in everywhere - so they are unavoidable, but it is of course a good idea to try and avoid consuming too many foods with high heavy metal levels, and I think it is fair to say our whey proteins are very much in the "low level" category :-)
