Millions of Americans Are Wasting Money on This Popular Supplement—Experts Say It Does “Absolutely Nothing”
Every morning, millions of Americans reach for a shiny multivitamin bottle, convinced they’re doing something good for their health.
But according to one biochemist, one of the ingredients inside those pills may be little more than marketing magic.
The “Essential” Mineral That Isn’t
Trivalent chromium—a form of the metallic element chromium—is often sold as a dietary supplement and added to multivitamins. For years, it’s been promoted as an “essential nutrient” said to boost energy, enhance muscle performance, and even stabilize blood sugar.
Yet according to Dr. Neil Marsh, a professor of chemistry and biological chemistry at the University of Michigan, decades of research tell a different story.
“Despite nearly 80 years of investigation, there’s no convincing evidence that chromium provides any measurable health benefit,” Marsh told The Conversation.
In other words: you could be spending money on a supplement that does… nothing.
Why People Think Chromium Is Essential
Humans do need small amounts of certain metals—called trace elements—to survive. Iron, zinc, copper, and manganese all help your body carry oxygen, heal wounds, and regulate enzymes.
When you don’t get enough iron, for example, you develop anemia, which can cause fatigue, weakness, and headaches. Supplements can fix that.
Chromium, however, doesn’t seem to work that way.
Your body absorbs less than 1% of the chromium you eat, and scientists haven’t found a single protein that actually needs it to function.
“There’s no biochemical evidence that chromium plays a role in any essential biological process,” Marsh explained.
That’s a problem for a substance that’s labeled “essential.”
A Health Myth Born in the 1950s
So where did the chromium craze come from? It started nearly 70 years ago with an experiment on lab rats.
In the 1950s, researchers noticed that rats fed a nutrient-deficient diet showed diabetes-like symptoms. When chromium was added, the rats appeared to recover. Excited scientists speculated that the metal could help humans regulate blood sugar too.
But those early experiments were riddled with flaws—by today’s standards, they wouldn’t even pass peer review. There were no proper controls, no clear dosage measurements, and no statistical proof that the effect wasn’t a coincidence.
Later, more rigorous studies produced inconsistent results. Some showed a slight improvement in blood sugar control; others showed none at all.
In the end, the rats that didn’t get chromium? They stayed perfectly healthy.
What Human Trials Have Found
Clinical research on people has been similarly underwhelming.
Dozens of studies have tested whether chromium supplements help patients with Type 2 diabetes regulate glucose levels—but findings have been inconclusive at best.
When chromium helps, it’s by a very small margin—too small to matter clinically.
“If there’s an effect, it’s marginal,” Marsh said. “There’s simply no clear evidence that the human body requires chromium at all.”
So Why Do Labels Still Recommend It?
The idea that chromium is necessary persists largely due to a 2001 report by the National Institute of Medicine’s Panel on Micronutrients.
The panel admitted the science was thin but still recommended adults consume around 30 micrograms per day—not because it was proven necessary, but because that’s roughly what people were already eating on average.
In other words, the “recommended daily intake” isn’t based on health outcomes—it’s based on habit.
Ironically, much of the chromium Americans consume doesn’t come from food at all. It leaches from stainless steel cookware and food processing equipment during manufacturing.
The Supplement Industry’s Shiny Distraction
Despite the lack of evidence, chromium continues to appear in everything from multivitamins to “blood sugar support” pills—often marketed with buzzwords like metabolic balance, insulin support, or fat-burning aid.
The global dietary supplement market is now worth over $180 billion, and chromium supplements alone account for millions in annual sales.
Yet most people buying them are, effectively, paying for placebo.
“There’s no harm in taking chromium,” Marsh noted, “but there’s also no measurable benefit. It’s a waste of money.”
The Bottom Line
Chromium’s health halo seems to have been built on decades of wishful thinking and weak science. Unlike iron, zinc, or copper, your body doesn’t appear to need it for any essential biological function.
So if you’re buying supplements to improve energy or balance blood sugar, experts say your money would be better spent elsewhere—like on a balanced diet, regular exercise, and real medical advice.
In short:
Chromium may sparkle in your faucet, but in your supplement bottle, it’s just a shiny illusion.

Chromium FAQ's
Is chromium safe to take?
Generally, yes—but it’s unnecessary for most people. High doses can irritate the stomach or cause mild kidney stress in rare cases.
Does chromium help with weight loss?
No major study has shown that chromium supplements significantly affect body weight or fat metabolism.
Can you get chromium naturally?
Yes. It’s found in small amounts in whole grains, meats, and some vegetables—but your body absorbs almost none of it.
Should I stop taking my chromium supplement?
If you’re otherwise healthy and not deficient in essential minerals like iron or zinc, most experts say there’s no need to take chromium at all.
Final Verdict:
Chromium might be a superstar in stainless steel—but when it comes to human health, it’s mostly hype.
