Whey Protein Isolate Cold-Filtration

I reached out to True Nutrition about a year ago and they sent their test results for their soy protein, rice protein concentrate, pea protein isolate, whey protein isolate ultra - CFM, whey protein isolate cold-filtration, whey protein concentrate, and RGBH/soy free whey protein isolate. Tests appear to have been performed by a company called Certified Laboratories in July 2024. I received test results for levels of lead, arsenic, cadmium, and mercury in each of the proteins I listed above. Here are the lead levels they provided: soy protein: 0.030 ppm rice protein concentrate: 0.362 ppm pea protein isolate: 0.025 ppm whey protein isolate ultra CFM: 0.024 ppm whey protein isolate cold-filtration: 0.023 ppm whey protein concentrate: 0.016 ppm rgbh/soy free whey protein isolate: 0.017 ppm I haven't typed out all the arsenic and cadmium and mercury levels because I am too lazy to type it all but if anyone is curious you can DM me and I can send you the PDFs. Or maybe I'll host them on google drive or something. Some math: For their rice protein concentrate, to reach 10 micrograms in a day, you would have to eat 33.33 grams of the protein concentrate (keep in mind there are often other fillers in the protein powder). 0.362(x) = 10μg --> x = 33.33 For something like the soy protein, to reach 10μg in one day, you would have to eat 0.030(x) = 10μg --> x = 333 grams TLDR: **For True Nutrition brand protein powder, most protein sources seem safe enough, but I'm probably going to avoid rice protein concentrate** **Edit:** Because I just read from other comments that California was suggesting 0.5μg per day, here is some more math. To consume 0.5micrograms of lead, you would have to eat: 16.67 grams of soy protein 1.38 grams of rice protein concentrate 20g of pea protein isolate 20.83g of whey protein isolate ultra CFM 21.74g of whey protein isolate cold-filtration 31.25g of whey protein concentrate 29.41g of rgbh/soy free whey protein isolate

I've been buying True Nutrition for ages. I get the isolate cold-filtration or the grass-fed. Premium vanilla, light intensity. Mixes great in cereal, oatmeal, smoothies.

TrueProtein cold filtration whey isolate, vanilla flavored at 1/2 strength.

soy isolate or beef protein isolate huge fan of true nutrition's offerings and their unflavored stuff (I add my own flavors so never get tired of the same one)

My nutritionist said that the cheaper the powder, the more likely it has elevated levels of lead. https://www.consumerreports.org/lead/protein-powders-and-shakes-contain-high-levels-of-lead-a4206364640/ It's more expensive, but he said he only uses stuff from True Nutrition, so that's what I do.

I use TrueNutrition and mix it in cold or hot coffee. It's delicious and even in the hot it's never curdled. I put mine in a blender bottle and give it a good shake before putting it in my cup.
