my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵) www.consumerreports.org/lead/protein...

consumerreports.orgProtein Powders and Shakes Contain High Levels of Lead - Consumer ReportsCR tests of 23 popular protein powders and shakes found that most contain high levels of lead.

the results of this investigation surprised me. since CR last tested protein supplements in 2010, protein mania has swept the nation. protein isolates (the key ingredient in supplements) are in everything these days, from pasta to starbucks cold foam but as the industry has grown, so have the risks

two of the products we tested — Huel's Black Edition meal replacement powder and Naked Nutrition's vegan mass gainer — had enough lead that our experts caution against using them at all a single serving of these protein powders contained between 1,200 and 1,600% of CR’s level of concern for lead

nearly all the plant-based products we tested had elevated lead levels: vegan powders had 9x as much lead as dairy and 2x as much as beef though dairy-based powders had the lowest levels, half were still too contaminated for safe daily use you may be asking: how could this be? well...

i was surprised to learn that bc most protein powders are considered dietary supplements, they basically fall into a regulatory grey area there's no federal limit on the amount of lead they can contain and neither manufacturers nor the FDA have to prove these products are safe before they're sold

there are currently about 12,000 registered supplement manufacturers. last year the FDA inspected only 600 of them! when the agency does do inspections, it overwhelmingly focuses on domestic manufacturers. that's a problem because a LOT of these materials are sourced from foreign factories

i feel like this story is particularly important right now, because protein-maxxing is *so* in vogue. before working on this, i believed i was woefully protein deficient it turns out that's just a myth that has been floating around for decades—the average american gets more than enough protein!!

I saw a lot of jokes after the election that the US has a lead poisoning problem (irritability, difficulty concentrating, mood disorders) and, welp…huh, considering the main protein powder user…huh…

Nitpicking, but your article says 1c of greek yogurt and 3.5oz of chicken is 61g of protein - I only count about 42g. Even if you weigh the 3.5oz after cooking (which isn't as typical) that's only 53g. Not that it negates anything else, but that bit stood out to me.

not only that, but research suggests there's little to no benefit to over-consuming protein unless you're actively restricting calories AND doing intense resistance training (in which case it helps you lose less muscle) but even the experts can't get folks to believe this! the myth is too strong!

"The study shows that U.S. dietary guidelines “promote a false equivalence that all proteins are equal, which indeed, they are not,” she writes. " You're probably eating enough protein, but maybe not the right mix share.google/1SRJBEm8CvyK...

share.googleYou're probably eating enough protein, but maybe not the right mixProtein is having a moment. But even if most people are eating enough protein, studies suggest they may not be eating the right mix.

Thank you for reporting on this topic. Have you thought about this in terms of waste? Considering the outsized env footprint of US populations, it’s stunning to see how much of this footprint is just waste. Like consuming so much protein just to have it pass through our bodies with no real benefit.

Botanicals are much worse than synthetically made vitamins and minerals because they leach it out of the soil. If you are concerned, ensure you are buying from a GMP-certified mfg facility. Theanine is usually synthetic, vitamins and minerals usually are also.

Oh no—this is incredibly distressing! I am severely underweight due to illness and depend on high protein nutrition shakes and protein powders. Did you find any that contained safe levels of lead? Thank you so much for this reporting!

Should we assume that if a very popular product isn’t included, it has safe levels of lead? Because I’m kinda shocked not to see Premier on this list; it’s available at literally every grocery and drug store within 10 minutes‘ drive from my house, including being one of the few options at Costco

Does this piece explain HOW lead gets into these products? Because absent someone purposefully putting it in there, I can’t imagine how it happens

Plants will absorb HMs out of contaminated soil. Vegan proteins have higher lead because you use the plant. Milk proteins have to go through the cow first so there’s some buffer there. A lot of farmland now has some degree of contamination

We can thank the Newt Gingrich congress for that. They ginned up a fake "they're taking away your supplements" to block regulation and get donations from manufacturers, and ever since it's been a wild west where you can make any snake oil claims you want as long as you say "not evaluated by the FDA"

Not any claim, there are ones that will earn you a warning letter and a hard time from the FDA but you basically have to claim it’s a cancer cure to get that far. But yes there are a ton of horseshit supplement claims out there

Maybe if y'all had considered that they are, and approached this from a risk to those who need them vs people who take them by choice you'd have a better article and test. Did you test Boost or Glucerna? Did you ask doctors, nutritionists, or NPs what they recommend or what facilities serve?

Pea plants absorb lead and other heavy metals from the soil as they grow, which end up in pea protein powder. There are other consumable plants that make great phytoremediators and uptake heavy metals.
