Experts Share The Worst Types Of Protein Powders To Avoid Because They May Contain Lead–Plus, Which To Use Instead
November 9, 2025 by Mariam Qayum
Protein powders have become a staple in fitness routines and daily diets, but not all powders are created equal. Recent insights from Dr. Johnny Hadac reveal a concerning trend: some protein powders, particularly plant-based varieties, may contain higher levels of lead compared to traditional whey proteins.
“Lead found in protein powders is on average much higher in plant-based proteins versus whey,” Hadac explains. While plant-based powders can be a convenient option for vegans or those avoiding dairy, the presence of heavy metals poses a potential long-term health risk, especially for individuals who consume these supplements daily. Chronic lead exposure can affect kidney function, brain health, and overall well-being.
On the other hand, whey protein powders are widely studied and generally considered safe when sourced from reputable brands. Whey contains all 20 amino acids, including the nine essential amino acids our bodies cannot produce on their own. According to Hadac, whey protein can support muscle growth, help manage appetite by keeping you fuller for longer, and assist with calorie control—making it an effective tool for both fitness and weight management.
The supplement industry is not heavily regulated, so contamination can sometimes occur during manufacturing or from sourcing low-quality ingredients. “It comes as a disappointment to a lot of companies that do whey proteins, but thankfully, us at Muscle Dummies, we make sure to third-party test all of our supplements for any heavy metals to ensure there is no lead in any of our products,” Hadac adds. Third-party testing is an important measure for consumers looking to protect their health while still supplementing their diet effectively.
