Which popular protein powders have the least amount of contaminants like PFAS “forever chemicals,” phthalates, heavy metals, glyphosate, and other pesticides? Mamavation sent eleven popular (mostly organic) chocolate protein powders to two EPA-certified laboratories to find out which brands were the “cleanest” from certain toxic contaminants.
Which brand of protein powder came out on top? You’ve trusted Mamavation to bring you topics like cinnamon tested for heavy metals and glyphosate, salt tested for heavy metals and microplastics, olive oils tested for toxic phthalates, and safest cookware, now join us for another consumer study revealing results of protein powders tested for glyphosate, 500+ additional pesticides, heavy metals, PFAS, and phthalates.

Heavy Metals, PFAS, Pesticides and Phthalates Found in Popular Protein Powders
Mamavation sent eleven popular chocolate-flavored (mostly organic) protein powders to two EPA-certified laboratories testing for PFAS analytes including PFOA/PFOS, phthalates, heavy metals, glyphosate, and 500+ additional pesticides.
The contamination results were surprising considering how expensive most of these products were. (We also did a breakdown of the costs per serving at the bottom of this post with the results.) Here’s the outcome of contaminants that were found according to our labs:
91% of protein powders had levels of lead that would require a Prop. 65 warning in California — That’s 10 out of 11 protein powders with lead above 0.5 ug/day. Ranges from 0.2567 ug/day to 1.7848 ug/day of lead. Therefore using one serving size of protein powder would exceed the recommended amount of lead per day.
19% of protein powders had levels of cadmium that would require a Prop. 65 warning in California — That’s 2 out of 11 protein powders with cadmium above 4.1 ug/day. Ranges from 0.411516 ug/day to 6.5512 ug/day of cadmium.
100% of protein powders did not require a Prop. 65 warning in California for arsenic.
100% of protein powders did not have detectable mercury.
One protein powders had detectable levels of glyphosate — That’s 1 USDA organic brand out of 11 organic and conventional brands tested. Ranges from non-detect to 42 ppb.
27% of protein powders had other detectable pesticides present — Two of these brands were USDA organic, while 1 was not USDA organic. Ranges from non-detect to 128 ppb.
55% of protein powders contained specific PFAS chemicals — That’s 6 out of 11 protein powders had detectable levels of specific PFAS chemicals, such as PFOA, PFBA, or PFHpA. Ranges from non-detect to 1.942 ng/g (ppb).
71% of vegan protein powders contained specific PFAS chemicals — PFOA, PFBA, and/or PFHpA. That’s 5 out of 7 vegan protein powders.
67% of pea protein powders contained specific PFAS chemicals — PFOA, PFBA, and/or PFHpA. That’s 6 out of 9 pea protein powder products. (Note: Most protein powders containing animal-based ingredients also contained pea protein, so there was overlap.)
75% of animal-based protein powders did not contain specific PFAS chemicals — That’s 3 out of 4 products containing whey or bone broth protein.
64% of protein powders contained ortho-phthalates — That’s 7 out of 11 protein powders. Ranges from non-detect to 377 ppb.
Only ONE product we tested passed all product testing — It had detectable levels of lead, cadmium, and arsenic, but not high enough to set off a Prop. 65 warning in California. This was the product we will recommend at the end of this post, which also ironically was not the most expensive.
Linda S. Birnbaum, Scientist Emeritus and Former Director of the National Institute of Environmental Health Sciences and National Toxicology Program and Scholar in Residence at Duke University, Adjunct Professor at the University of North Carolina, and Yale University had this to say after her scientific review: “I’m very disappointed in the protein powder category.
So many people, including pregnant women, rely heavily on protein powder every day. Knowing what we know now about these premium brands, you can safely assume protein powders are potential sources of many contaminants like PFAS, lead, and phthalates.”
Contaminants Included in Mamavation’s EPA Certified Laboratory Testing
Mamavation sent eleven popular chocolate-flavored (mostly organic) protein powders to two different EPA-certified laboratories looking for specific problematic contaminants that would not be listed on an ingredient panel.
These ingredients are never found on an ingredient label because they are not considered “intentionally added” and would instead be considered more of a contaminant from manufacturing, transportation, storage, and/or farming practices. However, just because these contaminants are not “intentionally added” doesn’t mean they won’t impact your health over time and usage.
Our labs tested for the following contaminants and found most of them present in most of the chocolate protein powders we tested to varying degrees:
40 specific PFAS “forever chemical” analytes
Glyphosate
500+ additional pesticides
Phthalates
Lead — heavy metal
Arsenic — metal
Cadmium — heavy metal
Mercury — heavy metal
Terrence Collins, Teresa Heinz Professor of Green Chemistry and Director of the Institute for Green Sciences at Carnegie Mellon University had this to say after his scientific review:
“The brightest perspective of this superb multifaceted study is that one protein powder came through clean of all tested contaminants. Consumers could send a powerful message by shifting their buying preferences to this brand. But this Mamavation study invokes broader questions for American food and for the meaning of the ‘organic’ label.
Do we want to be ingesting health food products that we think are good for us while being unsure about possible contamination by toxic metals, pesticides and industrial chemicals that can impair the development of our children and instead harm our health? How can we better police organic labeling — shouldn’t some government agency be following up and regulating better?
Many of the Mamavation — identified toxic contaminants are deliberately commercially applied or may sneak into products through nonorganic agricultural methods — so how can we better promote authentic organic foods? Should we institute wider government-funded testing and subsidize the expansion of organic farming to neutralize the pricing advantages of nonorganic food products?”
• PFAS “forever chemical” analytes tested including PFOA and PFOS — PFAS “forever chemicals” are per- and polyfluoroalkyl substances used as stain-resistant, water-resistant, and oil-resistant chemicals in commerce. They have been used for decades in consumer products, manufacturing, and building materials. Here are some of the health effects associated with different PFAS “forever chemicals:”
Increased risk of allergies and asthma in young children
Affected growth, learning, and behavior of infants and older children
Increase cholesterol levels
Metabolic diseases like obesity and diabetes
Lowered a woman’s chance of getting pregnant
Increased risk of kidney and testicular cancers
Disrupted normal thyroid function
Increases risk of acute lymphoblastic leukemia in children
It’s also very clear based on biomonitoring evidence from the Center for Disease Control (CDC) that PFAS are in virtually all Americans. Therefore, these exposures can harm most Americans.
For this investigation, we elected to test for forty specific PFAS analytes listed below using EPA method 1633:
Perfluorobutanoic acid (PFBA)
Perfluoropentanoic acid (PFPeA)
Perfluorohexanoic acid (PFHxA)
Perfluoroheptanoic acid (PFHpA)
Perfluorooctanoic acid (PFOA)
Perfluorononanoic acid (PFNA)
Perfluorodecanoic acid (PFDA)
Perfluoroundecanoic acid (PFUnA)
Perfluorododecanoic acid (PFDoA)
Perfluorotridecanoic acid (PFTriA)
Perfluorotetradecanoic acid (PFTeA)
Perfluorobutanesulfonic acid (PFBS)
Perfluoropentanesulfonic acid (PFPeS)
Perfluorohexanesulfonic acid (PFHxS)
Perfluoroheptanesulfonic Acid (PFHpS)

Scott Belcher, Associate Professor with the Center for Environmental and Health Effects of PFAS at North Carolina State University, had this to say about the consumer study after his scientific review:
“Unfortunately, PFAS are essentially everywhere, and it is not surprising, based on my scientific experience, that they are increasingly found in food products. Regardless of the source of protein in these supplements, be it dairy or plant-based protein, PFAS from contaminated water and biosolids from sewage sludge, are taken up into plants and animals where they interact with proteins.
The findings shown here show clearly that the processing used to produce purified protein products does not eliminate the presence of these toxic chemicals and that food, in addition to our water, is a clear source of exposure.
Increasingly, I keep coming back to the 1964 Stanley Kubrick film Dr Strangelove and the quote of General Jack D. Ripper: Fluoridation is the most monstrously conceived and dangerous communist plot we have ever had to face.
Based on the increasing body of scientific and consumer-based research I believe that history is going to look back and find that General Ripper was only wrong about the perpetrators of the plot.”
• Glyphosate — Glyphosate [N-(phosphonomethyl) glycine] is the active ingredient in glyphosate-based herbicides (GBH) and is the most popular herbicide in the world. Environmental exposure to this broad-based herbicide has increased dramatically since the introduction in 1996 of “Round-up Ready” genetically modified (GMO) crops for soybean, maize, and cotton varieties.
“Round-up Ready” genetically modified crops made it possible to utilize glyphosate as a broadcast herbicide while not killing the crops they were sprayed on. Glyphosate is also extensively used for deforestation efforts, such as killing brush in fire zones, and is also relied on heavily by landscapers to kill weeds on green belts and golf courses.
Ultimately, glyphosate is used for eliminating weeds and shrubs, such as annual and perennial grasses, broadleaf weeds, and woody species.
Glyphosate was originally patented as a chelator and an antibiotic, which means it has the ability to stop nutrient absorption and decimate delicate gut flora. These two simple facts explain why glyphosate is so damaging to the overall health of your body and has been linked to spreading antibiotic-resistant bacteria.
Glyphosate has also been deemed a “probable carcinogen” by the World Health Organization and added to the Prop. 65 list of carcinogens and reproductive toxins in California.
Mamavation sent eleven chocolate protein powders to our EPA Certified lab to test for glyphosate, glufosinate, and AMPA (metabolites or breakdown products) using liquid chromatography and mass spectrometry (LC-MS/MS) at 10 parts per billion (ppb) detection limit. This is the standard test going as low as possible in a commercial lab. (University labs or experimental labs using non-standardized testing may be able to go lower.)
• 500+ additional pesticide laboratory test for protein powders — testing details — Eleven chocolate protein powder brands were sent to our EPA-certified lab and analyzed using two different methods which totaled testing for 587 pesticides down to the lowest standardized level. Our laboratory found the following pesticides in those chocolate protein powders:
◦ Fluopyram — Fluopyram is a fungicide and nematicide used to combat diseases such as gray mold, powdery mildew, sclerotinia, and monilia diseases in agriculture. It’s applied on crops like potatoes, sugar beets, dried beans, apples, wine grapes, and strawberries. The EPA determined it’s “likely to be carcinogenic to humans.”
◦ Propiconazole — Propiconazole is a fungicide that is commonly used in agriculture on mushrooms, corn, wild rice, peanuts, almonds, sorghum, oats, pecan, and fruit including apricots, bananas, plums, prunes, peaches and nectarines.
The Environmental Protection Agency (EPA) has classified propiconazole as a possible human carcinogen. Animal studies have linked health impacts to the liver because it has been linked to the increased incidence of benign and malignant liver cell tumors among male laboratory rats.
Even low yet chronic doses were associated with higher incidences of liver tumors. Increased cleft palate malformations were also noted in additional animal studies.
◦ Piperonyl butoxide (PBO) — This chemical is not a pesticide itself, but instead it’s an adjuvant used to enhance the potency of certain pesticides like carbamates, pyrethrins, pyrethroids, and rotenone. Acute studies identify potential hazards from exposures such as dermal toxicity, eye irritation, inhalation toxicity, oral toxicity, skin irritation, and skin sensitization.
PBO was found to be capable of causing brain and face malformations and other birth defects in mice exposed during early development. The EPA has categorized piperonyl butoxide as a group C carcinogen based on limited evidence of cancer in laboratory animals.
◦ Tebuconazole — This fungicide is listed as a possible human carcinogen by the EPA. Tebuconazole was introduced to the market in 1989 by Bayer and was initially used on cereals, but today it’s used on peanuts, bananas, and soybeans as a foliar fungicide to control a range of fungal diseases. It’s also used as a seed treatment.
This chemical poses potential developmental toxicity, genotoxicity, reproductive toxicity, mutagenicity, hepatotoxicity, neurotoxicity, cardiotoxicity, and nephrotoxicity via animal studies.
◦ Zeta-cypermethrin — Cypermethrin is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications. It’s also used in consumer products as a fast-acting neurotoxin for insects such as ants and cockroaches. Cypermethrin is also toxic to fish, bees, aquatic insects, and cats.
Cypermethrin is classified as a possible human carcinogen by the EPA, because it causes an increase in the frequency of lung tumors in mice. Animals exposed to Cypermethrin during pregnancy gave birth to offspring with developmental delays, abnormal sperm issues, and genetic damage.
If exposed to cypermethrin during pregnancy, rats give birth to offspring with developmental delays. In male rats exposed to cypermethrin, the proportion of abnormal sperm increases. It is also linked to genetic damage.
• Phthalates — Phthalates are linked to many health effects from several studies on both animals and humans. This is very problematic because phthalates are linked with hormone disruption of the endocrine system, which regulates the body’s hormones, even in trace amounts in low concentrations.
Epidemiological studies have revealed that exposure to phthalates adversely affects the level of hormones within the body, which can impact several important health functions. Here are some health effects phthalate exposure is linked to.
Attention Deficit Hyperactivity Disorder (ADHD)
Type 2 diabetes and insulin resistance
Thyroid function and increased risk of thyroid cancer
Females — Pregnancy loss and preterm birth, low birth weight, earlier menopause
Males — Genital development, semen quality, reduced “masculine” play, inhibits testosterone production, shortened anogenital distance, or shortened “taint,” shortened length of penis
Mamavation’s EPA-certified lab tested for the following phthalates. This is not a complete list of all the phthalates that are allowed to be present as an indirect food additive according to the FDA, however, this list goes above and beyond what is already restricted by the European Union or the State of California.
Diethyl phthalate (DEP)
Di-n-propyl phthalate (DPP)
Diisobutyl phthalate (DIBP)
Dibutyl phthalate (DBP)
Dihexyl phthalate (DnHP)
Benzyl butyl phthalate (BBP)
Dicyclohexyl phthalate (DCHP)
Diisononyl phthalate (DINP)
Di-n-octyl phthalate (DnOP)
Diisodecyl phthalate (DIDP)
Bis(2-ethylhexyl) phthalate (DEHP)
Dimethyl phthalate (DMP)
Bis(2-propylheptyl) phthalate (DPHP)
Didecyl phthalate (DDP)
• Heavy metals: lead, cadmium, mercury and arsenic — To test protein powder for metals our EPA-certified lab used 0.5 g of sample weighed directly in a clean microwave vessel or first on a weighing tray and then transferred quantitatively to the microwave vessel. Concentrated nitric acid (10 mL) was added and the sample was allowed to pre-digest for 15 minutes before being subjected to microwave digestion.
After microwave digestion was completed, the vessels were left to cool for 15 minutes and the caps were loosened to vent any excess red gas (nitrogen dioxide) present. The digested material was subsequently transferred to a 50 mL conical tube (the microwave vessel rinsed twice with reagent water) and diluted to the 25 mL graduation mark.
The solutions are then shaken, vented, then centrifuged. Samples were then ready for ICP-MS analyses. Our EPA-certified laboratory tested each protein powder for the following metals:
◦ lead
◦ arsenic
◦ cadmium
◦ mercury
Mamavation then adjusted the result to reflect California Prop. 65 based on serving size into ug/day results.
◦ Federal vs. California Prop. 65 “safe harbor” levels for heavy metals like lead and arsenic — So what levels of lead, arsenic, mercury, and cadmium are concerning to public health officials? According to the Food and Drug Administration, the levels inside your food that you are allowed to be exposed to are as follows:
▪ “Heavy metals as lead (as Pb), should not be in your food or supplements at more than 10 parts per million (ppm)
▪ Arsenic (as As), should not be in your food or supplement at more than 3 parts per million (ppm)
▪ Mercury (as Hg), should not be in your food or supplements at more than 1 part per million (ppm)
▪ Cadmium levels (as Cd) in bottled water should not exceed 0.005 parts per million (ppm)”
When it comes to protecting consumers, California has far more stringent health protective levels, but instead of banning products, they require manufacturers to use label warnings instead.
California’s Prop. 65 established “safe harbor levels” for most of the heavy metals we tested: arsenic, cadmium, lead, and mercury. Prop. 65 requires businesses to provide warnings to consumers living in California about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm.
These chemicals can be in the products they purchase, in their homes or workplaces, or released into the environment. By requiring this information to be provided, it enables consumers in California to make informed decisions about their exposure to these chemicals.
Here are the No Significant Risk Levels (NSRL) and the Maximum Allowable Dose Levels (MADL) established by the State of California for the heavy metals we tested:
Arsenic — 0.06 ug/day (inhalation), 10 ug/day (except inhalation)
Cadmium — 0.05 ug/day (inhalation), 4.1 ug/day (oral)
Lead — 0.5 ug/day level for reproductive toxicity, 15 ug/day (oral) for carcinogens
Mercury — No established levels in California, so the Federal maximum contaminant level for mercury would be followed instead.
Mamavation’s Raw Data from Our EPA-Certified Laboratory Ranked
Mamavation sent two sets of eleven brands of premium chocolate protein powders to different EPA-certified laboratories looking for traces of contaminants:
500+ pesticides (which is more comprehensive than other testing we’ve seen)
Glyphosate
40 PFAS “forever chemical” analytes like PFOA and PFOS. (This is different from our other studies where we measured total organic fluorine.)
Heavy metals (lead, cadmium, mercury and arsenic)
Phthalates
All products were sent to the laboratory in original packaging and purchased between November 2023 and March 2024. Products were selected by Mamavation community members representing what they are already buying and using in their homes to feed their families.
Some protein powder was donated by community members, however, most products were purchased by Mamavation directly. We could not purchase and test all the recommended brands because we had a limited budget for this testing.
After analyzing the results of each product, we decided to categorize products into three categories.
• Not our favorite protein powders — These protein powders had detectable levels of specific PFAS analytes that were quantifiable and/or had detectable pesticides. Most of these products also had heavy metals that were above warning levels for Prop. 65 in California and phthalates.
• Better protein powders — Our lab did not find quantifiable PFAS or pesticides in these products, but it did find at least one heavy metal at Prop. 65 warning levels for California, and/or detectable phthalates, and/or detectable PFAS that were not quantifiable. PFAS which was not quantifiable means the instrumentation was able to detect specific PFAS but was not able to say how much of it was there because it was so little.
• Best protein powders — This product did not have any detectable contaminants such as PFAS, phthalates, glyphosate, or 500+ other pesticides, and had levels of heavy metals that did not require a Prop. 65 warning.
