The report was carried out by Client Stories (CR), a nonprofit group staffed with each journalists and scientists that conducts unbiased product testing.
Testers Checked out Dairy, Beef, and Plant-Primarily based Dietary supplements
CR investigators checked out a spread of dairy, beef, and plant-based protein dietary supplements, together with powders and ready-to-drink shakes. The workforce bought two to 4 numerous every product from numerous sources, together with on-line, big-box shops, and diet shops.
A “lot” is a selected group of merchandise which are produced, processed, or packaged underneath the identical situations.
Key findings included:
- About 70 p.c of examined merchandise delivered an quantity of lead per serving that was larger than CR’s day by day “degree of concern,” with some exceeding that degree greater than tenfold.
- Three merchandise additionally exceeded the extent of concern for cadmium and inorganic arsenic — poisonous heavy metals categorised as possible and recognized human carcinogens (cancer-causing compounds), respectively, by the Environmental Safety Company.
- In contrast with testing from 15 years in the past, common lead ranges had been larger, and fewer merchandise had undetectable lead.
- Plant-based powders confirmed the very best contamination. Two merchandise had lead ranges so excessive (1,200 to 1,600 p.c of the day by day degree of concern) that Client Stories advises not utilizing them in any respect.
- On common, plant-based merchandise had 9 instances extra lead than dairy-based ones, and twice as a lot as beef-based powders.
- Whereas dairy-based protein powders usually had the bottom ranges, about half nonetheless exceeded CR’s threshold for secure day by day use.
- Vanilla-flavored powders tended to have the bottom heavy metallic ranges, whereas chocolate-flavored ones had the very best.
How A lot Lead Is Too A lot?
This evaluation is a crucial reminder that there may be hint quantities of lead in protein powders, and if producers aren’t cautious about managing the amount of lead, ranges can proceed to creep up, says Pieter Cohen, MD, a complement researcher and affiliate professor at Harvard Medical College in Boston.
“That’s a severe concern, as a result of the lead can keep within the physique for months or longer,” says Dr. Cohen, who wasn’t concerned within the analysis.
The Second Regarding Report on Protein Powders in Much less Than a Yr
Not like they do with drugs, the FDA doesn’t approve or routinely check dietary dietary supplements earlier than they attain retailer cabinets, says Cohen. Producers are chargeable for their very own security testing, and there are not any enforceable federal limits for heavy metals in protein powders. The shortage of clear, constant requirements leaves customers largely on their very own to evaluate danger, he says.
How Did Completely different Manufacturers of Protein Powder Stack Up?
Investigators put the merchandise into classes based on the quantity of lead discovered within the powder or shake. Client Stories made the next suggestions:

Complement Producers Say the Report Leaves Out Vital Context
Jeff Ventura, vp of communications for the Council for Accountable Diet, the main commerce group representing complement producers, says individuals ought to maintain a number of issues in thoughts when deciphering the findings
“Whereas we recognize that Client Stories has printed some element on its methodology, we notice that vital context is lacking — particularly how merchandise had been chosen, whether or not testing mirrored typical client use, and the way its ‘ranges of concern’ had been derived. With out harmonization to established federal benchmarks, and even precise security danger, such proprietary thresholds can overstate danger and trigger pointless alarm,” says Ventura.
The degrees detected within the report don’t essentially add as much as a well being hazard, he says.
“The mere detection of heavy metals corresponding to lead, cadmium, or arsenic doesn’t equate to a well being hazard. Trendy testing strategies are terribly delicate and able to figuring out hint quantities of naturally occurring parts which are discovered broadly in soil, water, and vegetation,” says Ventura.
What to Contemplate When Weighing the Advantages and Dangers of Protein Powder
Cohen agrees, saying, “I’m simply not satisfied that there are various frequent situations by which individuals want so as to add protein powder to the food plan to be more healthy. I feel there’s way more hype than there’s precise proof to assist it.” He suggests that individuals give attention to getting their protein wants met by means of a wholesome and balanced food plan.

In the event you do use protein powder, Client Stories recommends that you just do the next:
- Keep away from day by day use, particularly of plant-based or chocolate-flavored varieties.
- Select whey-based or collagen powders, which usually have decrease ranges of lead and cadmium.
- Verify for third-party testing or NSF certification, which point out compliance with unbiased security requirements.
- Search for clear manufacturers that make heavy metallic testing outcomes public.
- Watch serving sizes. Extra powder doesn’t essentially imply extra profit.
