what i heard is from a friend who is a chemist and he says some of there products are just fine for human consumption but some are not that they have high levels of heavy metals. i made a mistake, i am sorry, i should have said "i have heard some of there products are not good for food consumption" but you can probably say that about any brand with multiple products i would think. i just want people to be careful what they put in there food, and not get sold "SNAKE OIL" from some
nutrient company.
this is all just my personal opinions , i am not a proffesional
