New Delhi, October 10: A shocking new investigation by Consumer Reports (CR) has found that several popular protein powders and ready-to-drink shakes — used by millions worldwide — contain unsafe levels of heavy metals, including lead, raising major health and safety concerns.
The report, published this week, revealed that more than two-thirds of the 23 protein products tested had lead levels exceeding daily safe limits, with some containing up to 10 times more lead than is safe to consume in a single day.
Major Findings: Dangerous Lead Levels in Protein Supplements
Consumer Reports tested 23 popular protein powders and drinks — both plant-based and dairy-based — and found alarming results.
According to Tunde Akinleye, the CR food safety researcher who led the study, plant-based protein products contained nine times more lead than dairy-based proteins and double that of beef-based proteins.
“Almost all the plant-based protein products we tested had elevated lead levels. Two of them had so much lead that we strongly advise against their use,” said Akinleye in an official CR statement.
The report also noted that dairy-based proteins, such as whey, generally had the lowest levels of contamination, but even half of those tested contained enough heavy metals for CR’s experts to discourage daily use.
Products with the Highest Lead Concentrations
Among the products tested, several popular brands showed particularly high concentrations of lead per serving:
- Naked Nutrition Vegan Mass Gainer – 7.7 micrograms (mcg)
- Huel Black Edition (Chocolate) – 6.31 mcg
- Garden of Life Sport Organic Plant-Based Protein (Vanilla) – 2.76 mcg
- Momentous 100% Plant Protein (Chocolate) – 2.33 mcg
Consumer Reports sets its level of concern for lead at 0.5 micrograms per day. Alarmingly, 70% of the tested products exceeded 120% of that threshold.
While these levels may not cause immediate toxicity, CR experts cautioned that prolonged exposure to such contamination could contribute to serious health issues, including neurological damage, kidney dysfunction, and developmental problems in children.
Lead Levels Higher Than 15 Years Ago
Akinleye pointed out that the average lead level found in protein powders is higher than it was 15 years ago, suggesting that contamination has worsened over time.
“We found fewer products with undetectable amounts of lead compared to previous years,” Akinleye said. “For many consumers, there’s more to lose than to gain from using these supplements daily.”
Consumer Reports attributed the rising contamination to several factors — including soil pollution, unregulated sourcing of plant materials, and inadequate manufacturing oversight in supplement industries.
Consumer Reports Urges Caution, Not Panic
Despite the alarming results, Consumer Reports emphasized that there is no immediate cause for panic for occasional users of these products.
“Many of these powders are fine to have occasionally, and even those with the highest lead levels are far below the concentration needed to cause immediate harm,” CR clarified in its report.
However, experts strongly recommend limiting regular consumption, especially among athletes, gym-goers, and individuals using supplements daily for fitness or dietary goals.
Akinleye added,
“We advise against daily use for most protein powders since many have high levels of heavy metals and none are necessary to hit your protein goals.”
Public Reaction and Industry Response
The findings have sparked widespread debate among fitness enthusiasts and nutrition experts. Several users took to X (formerly Twitter) to express concern over the safety of protein powders that are heavily marketed as health supplements.

Meanwhile, some nutrition brands have issued statements claiming that their products are tested regularly and meet government safety standards. However, Consumer Reports noted that FDA regulation of dietary supplements remains limited, leaving room for unsafe contamination levels to go unchecked.
Why This Matters: A Growing Health Concern
The global protein supplement market is valued at over $20 billion, with millions relying on these products for muscle gain, weight loss, or meal replacement. The discovery of high lead levels could have major implications for public health, consumer trust, and industry regulation.
Health experts warn that chronic exposure to lead, even in small amounts, can cause long-term health effects, particularly for pregnant women, children, and those with compromised immune systems.
“Heavy metal accumulation happens gradually. People who take these products daily over months or years are at the highest risk,” said a nutritionist interviewed by TheTrendingPeople.com.
Background: Past Concerns Over Contamination
This is not the first time protein powders have come under scrutiny. In 2018, the Clean Label Project, a nonprofit organization, published a similar report revealing that many top-selling protein supplements contained heavy metals, including lead, arsenic, and cadmium.
The latest CR findings suggest little improvement in product safety, despite growing awareness and consumer demand for transparency.
What Consumers Can Do
Consumer Reports recommends a few steps for safer supplement use:
- Check product labels for third-party testing certifications.
- Avoid daily consumption of protein powders unless prescribed.
- Opt for whole-food protein sources such as eggs, lentils, fish, and dairy.
- Report adverse effects from supplements to the U.S. Food and Drug Administration (FDA).
Final Thoughts from TheTrendingPeople.com
The new findings by Consumer Reports serve as a wake-up call for consumers and regulators alike. While protein powders remain a convenient supplement option, the lack of stringent safety oversight poses a real threat to public health. Until stronger regulatory measures are enforced, experts urge caution, moderation, and greater transparency from manufacturers.
