ND products testing positive for heavy metals

I just got a shipment of L Carnosine and Mg glycinate today. I tested them both for heavy metals. Both are positive for lead and the Mg glycinate also tested positive for cadmium. I used 2 different test strips, both tested for lead only (both tests positive for each supplement) and one tested for multiple heavy metals. Has anybody else tested their supplments? For comparison my ND L Theanine tested negative for all metals .

This is concerning considering that I recently finished a 1 year supply of MG glycinate…

There are no heavy metals in our products. You can't test those supplements with paper strips, as they have tons of false positives due to matrix interferences from the way the chemistry works. I talked about it in my below comment.
