Consumer Reports Uncovers Lead in Popular Protein Powders: NPR

A recent investigation by Consumer Reports has revealed the presence of lead in various popular protein powders and shakes. Over two dozen brands were tested, showing that a significant number contain concerning lead levels. While this information has raised alarms, the organization advises moderation rather than panic.

Key Findings from the Consumer Reports Study

The study examined 23 protein powders and ready-to-drink shakes available in stores and online, covering a three-month period starting last November. The findings, released recently, indicated that:

• More than two-thirds of the products contained lead levels exceeding what experts consider safe for daily consumption.
• Some products had lead concentrations exceeding safe limits by more than 10 times.
• Plant-based protein powders showed especially high lead levels—averaging nine times higher than dairy-based options.
• Half of the tested products had lead levels that experts recommend avoiding with daily use.

Consumer Caution

Consumer Reports warns against daily consumption of protein shakes but reassures that most tested products can be safely consumed occasionally. The risk of lead exposure arises not from single servings but rather from repeated high-dose exposure. Lead exposure can lead to serious health issues, including reproductive problems and cognitive impairments.

Regulatory Implications and Industry Response

The findings are currently under review by the Food and Drug Administration (FDA), which is assessing data from various heavy metal sampling efforts. The Council for Responsible Nutrition (CRN), a dietary supplement trade group, emphasized that tracing heavy metals in products doesn’t necessarily indicate a health risk. They noted that exceeding Consumer Reports’ thresholds does not equate to violating government safety limits.

Consumer Reports’ Quality Recommendations

Consumer Reports categorized the protein powders based on lead levels and safety concerns:

• Seven products were labeled as “better choices for daily consumption.”
• Twelve products are deemed “okay to eat occasionally.”
• Two products, with the highest lead levels, include Naked Nutrition’s Mass Gainer (7.7 micrograms per serving) and Huel’s Black Edition powder (6.3 micrograms per serving), which should be limited to weekly consumption.

The Need for Enforcement

There are currently no federal limits on heavy metals in dietary supplements, which raises concerns among consumer advocates. The FDA suggests reference levels for lead but does not enforce these guidelines as hard requirements. Consumer Reports is urging the FDA to establish mandatory lead limits to better protect consumers from potential health hazards.

Advice for Consumers

As consumers navigate their protein powder options, it is advisable to:

• Avoid products with California Proposition 65 warnings, clearly marked with bright yellow labels.
• Consult Consumer Reports’ recommendations when selecting protein powders.
• Prefer dairy-based protein options, as they generally have lower lead levels.

Although the market is flooded with protein-rich products, whole foods like Greek yogurt, nuts, and legumes can fulfill nutritional needs without the added risks associated with supplements. Ultimately, consumers should focus on informed decision-making and moderation.
