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 .

I also got some creatine today and that was negative for all heavy metals.

Creatine doesn't contain minerals that will cause cation interference with your strips, nor is is a chelator that will pull other minerals in to do the same. Stop misusing cheap paper strips to test supplements!
