mercury levels in this protein powder product?

[electroBeam]

I'm all for avoiding metal but how TF do you practically verify which foods/supplements to buy and which foods/supplements not to buy based on metal levels?

For example, should I drink this protein powder or not if I care about lowering my metal levels: https://www.bulknutrients.com.au/products/earth-protein?gclid=CjwKCAiA5t-OBhByEiwAhR-hmy2MW_jiYmlbC_YPZCswrZ-c741YsfZPUxSOF5mHBiCVYDsxY3g1uhoCGY8QAvD_BwE

I could replace the shakes with 12 eggs: https://www.sunnyqueen.com.au/products/organic-free-range-eggs

but how do I know for sure those eggs have less metal then the protein powder? If it doesn't then I'm wasting lots of money as eggs are not optimized for protein powder.
