89% of Sports Supplements Tested Did Not Label Their Ingredients Accurately

What is in your sports supplement? Maybe it’s not what you think it is. A test of 57 sports supplements showed that 23 (40%) did not even have detectable quantities of certain ingredients listed on their labels. as described in a research letter just published i JAMA Open Network. In fact, 89% of those products had labels that incorrectly indicated the quantities of those ingredients. And seven (12%) contained at least one ingredient banned by the US Food and Drug Administration (FDA). Hmm, that’s not very fun for those who were selling such supplements.

After all, an ingredient label isn’t supposed to look like a Tinder profile and make inaccurate claims, right? Otherwise, what’s to stop someone from listing things like pixie dust, moonbeams, Eye of Newt, and white truffles?

Well, the challenge is that the FDA doesn’t regulate what’s listed on supplement labels the same way they do medications and many packaged foods. So, unless you carry a time-of-flight liquid chromatography mass spectrometer or some other way to verify the ingredients in a supplement around you, you’re kind of relying on those who sell supplements to tell you the truth.

JAMA Open Network they found one group of people with a liquid chromatography time-of-flight mass spectrometer: a team from Harvard Medical School (Pieter A. Cohen, MD), the University of Mississippi (Bharathi Avula, PhD, Kumar Katragunta, PhD, Ikhlas Khan, PhD) and NSF International (John C. Travis). For this study, they used this kit to search for five ingredients that according to the study’s authors, “are promoted in dietary supplements for their stimulant or anabolic effects.” There were these five Game Rauwolfia online (whose derivatives are α-yohimbine), methionine (which is similar to caffeine), halostachine, turcesterone (a plant steroid), or octopamine (which is similar to norepinephrine).

The team ended up buying 63 different products and found that 57 of them had at least one of the five ingredients mentioned above on their labels. Specifically, 13 of the 57 were listed on their labels R. vomitoria, 21 of them methyllibrine, eight of them turcesterone, seven of them halastachine, and eight of them octopamine. The team mixed methanol with the powder from each of these products and then used liquid chromatography-quadrupole time-of-flight mass spectrometry to test the mixture to see how much of those five ingredients were actually present. and whether there were certain ingredients. which is prohibited by the FDA.

This is what the research team found. Although the hips do not fit, according to Shakira, it seems that many of the labels made a lot of fibers. Only six of the 57 products (11%) actually contained amounts of the ingredients that were within 10% of what the labels said. This meant that 89% of the products had labels that did not tell the truth about how much of the ingredients were in the products. In addition, seven of the 57 products (12%) contained at least one ingredient that would earn a “no, no” from the FDA, such as four different synthetic simulants, 1,4-dimethylamylamine, deterenol, octodrine, oxilofrine, and omberracetam.

Of course, this study had a bottle full of limitations. He used a convenience sample of supplements, which in this case does not mean they got the supplements from the convenience store. Instead, the research team only looked at supplements they could conveniently find online. It was also a relatively small sample. While 57 may seem like a lot when it comes to squirrels in your bathroom, it’s not the totality of sports supplements out there. So you shouldn’t label everyone who produces and sells supplements as a liar. However, the results indicated that there is a lot of smoke and mirrors out there.

Additionally, this was not the first study to find that many sports supplements were not labeled accurately. A study published in JAMA Internal Medicine in 2013 as a research letter probably a small number of people woke up to the amount of caffeine in 20 different sports supplements. That study found that five had actual caffeine levels that varied by more than 10% from what was listed on the label. These levels ranged from 27% to 113% of the labeled quantity.

Flash news. People can lie. So you have to deal with supplements and claims about them because you can profile on Tinder. A person can always say that he or she likes long walks on the beach and hates drama but hates the beach and loves drama. Likewise, you may not be able to trust what a sports supplement label says, unless you happen to be carrying around a time-of-flight liquid chromatography mass spectrometer.
