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

Congratulations, but I would hope you broke off the reporting when the startling results BEGAN coming in, like where the challenge drug performs statistically significantly WORSE than the placebo.

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

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.

The market has been so over saturated with protein products that it has become reliably off-putting for me. I avoid them, but only because I’ve done enough research about food from writing food features to know Americans don’t lack protein in their diets.

Sat back during Thanksgiving to listen to the young boyos in the extended family. A lot of chemical 'modifications' going on via gyms so they can bulk/muscle up.😬 Surgeons will talk about how hard it is to cut into some of these ppl when access is needed to interior problems.

😬😬😬 i drink protein shakes on a fairly regular basis, largely because it's easier than wrangling my brain into doing something more complicated. luckily, it seems that i'm under the weekly max recommended for the brand i use, but now i think i might just switch to yogurt drinks or something...

Without testing every brand, it’s probably safe to assume that pea protein powders contain elevated levels of lead. Reducing lead exposure is a personal health decision though. As the article states, no amount of lead is harmless and people disagree about how much should be considered “safe.”

I'd like to know what flavor was tested, the image was of a chocolate flavor and cocoa powder is key ingredient and common source of heavy metals. Entirely probable the non chocolate flavors would test better. (Double rich chocolate is so good tho. Mixes the best of any protein powder I've tried.)

Genuinely shocked that they didn’t include it; it’s available at literally every grocery and drug store within 10 minutes‘ drive from my house

so have I, but the ready to drink version. I wonder if these results apply to that as well? I'm guessing Huel just uses the same powder, and premixes it .................?

Based on the research I've done since this came out, it seems to be an issue with where vegan protein comes from, which is mainly peas. The lead is in the soil, which ends up in the peas, and it ends up more concentrated when they separate out the protein from a bunch of peas.

Since it wasn't included in the article, I reached out to Redcon1 to see if they would provide testing results. Safe to say I won't be having their stuff in my house anymore.

They are probably real numbers, with worse methodology. Perhaps they use samples from their main factory and not a random factory, maybe its a timing thing, etc. Am I saying that they cherry picked data? No... but I bet they had a good idea of where to get the best numbers before testing.

I love that the article keeps caveating their findings with "it's only dangerous if used regularly" about a thing the users use multiple times a day, every day. If you're supplementing protein, you're doing it all the time, usually in big doses.

Oh shiiiit. The one my partner and I use is on there. Not nearly as bad as the top two… still, I use it when I need to have some kind of meal but eating and cooking feel repulsive (bc mental illness). Or I need to get to work really fast. It’s definitely concerning.

Thank you for sharing this information with the world. I have passed this along to friends I care about, and a few of them were taking powders mentioned in the report. This matters. Thank you again.

There are those of us who are specifically told by doctors that we need to try to get x amount of protein per day, and a suplement is a great way to add to this protein intake without adding excess calories. Looks like I'm sticking to whey.

I'm about to start my winter workouts - thats 2 scoops - 4 times a day. I'm 58 and have been doing this for over 20 years. I'm not the only one - again tho I can't find any information on Gold Standard (Optimum Nutrition) etc.

No one in fitness has 1 serving! It 2 scoops (2 servings) more than once a day. I can't find a link for protein powders with the results. The brands you state here - are what the fuck brands - brands not used widely

Thank you for this (and CR for running it). This kind of deregulation/lack of oversight is at the heart of the "make america healthy" goon squad. They all have a supplement to sell, inventing problems for profit. And for some reason, we tolerate their attacks on science and medicine.

I thought it was just the steroid use that made alpha fitness podcast bros act like alpha fitness podcast bros. Who knew the secret ingredient was lead?

I was born in the 60s and lead levels have never proven cookie rooster engine filament turnstile me! - Reading the article, one is left asking "Ummm, they know lead is bad, right?"

How about, instead of a blanket "don't use these" we find out how the fuck to get the lead out of our food? Because I guarantee there's lead in a lot more stuff than just protein powder

Thanks for this. It looks like the article has the wrong picture for the Optimum Nutrition Gold Standard Protein Shake. I believe that product is the liquid shake in a carton, but the picture is the 100% whey powder (which is a separate product that was tested)

yes ty for pointing out, we're updating the image. our poor interactive got a bit too complicated and ended up using the wrong optimum nutrition image for this cell.

Watching you on Twit right now as well, talking about it....its crazy!!! You'd think all these organizations that are paid to ensure (pun intended) that this never happens.

Thank you for the investigation! If the FDA & federal regulations can't be bothered, does that mean nobody cares about this seemingly mass poisoning? P.S. not everyone consuming these products is a beefy body builder, many seniors use them to help ageing muscles.

I think as long as they actually do third party tests, they are probably legally clear: unless they make specific claims about how well they do on those tests. But given just how poorly they performed, and how prominent it is in their own marketing, I wouldn't want to be the defending lawyer.

breakfast is the trickiest meal of the day for me, given my stomach issues - can't have milk, have to limit bread/cereal, can't digest eggs. Plant-based shakes were a way for me to get something in my stomach without having a gastro-crisis on the drive to work, so I wasn't ravenous at lunch 🫠

A friend has health issue that severely restricts her diet. A few years ago, she told me that she eats prev night's dinner leftovers for breakfast. I tried it, & now I'm never hungry before lunch. At first, feels weird to eat like grilled chicken, rice, & steamed veg, but soon it's nbd (& healthy).

Text search showed no results for “Spiru-Tein” in article, which was the only one I ever used. Any info on that one? I only ever used the non-artificially flavored strawberry variety. Kinda liked it, but stopped using it when I was able to better feed myself (and it’s super expensive).

I really appreciate this reporting. I made the switch from whey to plant-based protein powders over ten years ago. I’ve been trying to use simple powders that don’t have too much sugar or other added ingredients. Studies like this make me wonder if I should simply walk away from them.

Many medical patients rely on protein drinks to make up for calories when they have difficulty eating. Can you do a follow-up article and interview doctors about what is or is not safe for persons in this situation?

You are just freaking out people who are in hospitals for - for example - bleeding ulcers - and are fed with bouillon and protein stuff, so that they can quickly be scoped again, and then a publication says MOST....
