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
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)
Vedge, true nutrition, myprotein vegan mix, ghost. Vedge renewed my hope in protein powder with their cookies and cream. 😁. Source: me, vegan 14ish years.
I use TrueNutrition protein powder; they have a lot of vegan bases (I use the pumpkin one). My smoothies are usually frozen strawberries, protein powder, cup of soy milk, 1/2 block of silken tofu, one or two dates, and then I'll put chia seeds on afterward for some fat. It usually clocks in at around 500kcal & 45g protein.
