Hidden Risks in Your Shake: Study Finds Lead in Protein Powders
A new investigation by Consumer Reports has raised concerns about the safety of popular protein powders and ready-to-drink shakes. The nonprofit tested 23 different products and found that more than two-thirds contained lead levels higher than what experts consider safe for daily consumption.
Key Findings
- Plant-based and chocolate-flavored powders tended to have the highest lead levels.
- Whey-based and vanilla options generally contained less lead, though they were not completely risk-free.
- The study used California’s strict safety threshold of 0.5 micrograms of lead per day as a benchmark.
- Some products contained up to 7.7 micrograms per serving, well above that limit.
Why It Matters
Lead is a toxic heavy metal that can accumulate in the body over time, potentially contributing to long-term health issues such as developmental problems, cardiovascular disease, and kidney damage. While the levels found in these supplements are not high enough to cause immediate harm, experts caution that daily use could pose risks.
What Consumers Can Do
- Prioritize whole foods like eggs, beans, fish, and lean meats for protein.
- If using supplements, limit daily intake and rotate products.
- Look for third-party tested brands that publish heavy metal screening results.
- Choose whey-based or vanilla-flavored powders when possible, as they tend to have lower contamination levels.
Protein powders remain a convenient option for athletes and busy consumers, but this study is a reminder that “clean” labels don’t always guarantee safety. Moderation and careful product selection are key.
