Personally, I’m beginning to be concerned about PFAS levels in protein powders and collagen.

W/o much data on this, I’ve assumed that there’s bound to be significant amounts in collagen, and often just use glycine instead. I’m not sure if there’s an affordable alternative for protein powder.

Wondering if whey made at home from kefir has the same level of contamination?

I also worry about PFAS. I filter water, etc. Do what you can, where you can.

I’m no expert but I’d assume it’s always a matter of degree. Homemade has got to be better than industrially manufactured and stored in plastic containers for long periods of time while heated (in transport?).

Consumerlabs tested multiple protein powders specifically to measure how much of the powder was actually protein. It was astonishing to me how little actual protein some contained! The best rated (I think something like 95% protein) was Nutricost which surprisingly is one of the more reasonably priced choices.

Whichever protein powder I use is likely less contaminated than the tuna fish I eat.

It looks like their study was updated, although the message is similar.
