Consumer Reports Unveils High Lead Levels in Some Protein Powders, Shakes
Recent findings from Consumer Reports reveal concerning levels of lead in various protein powders and shakes. The investigation analyzed 23 different protein supplements, encompassing dairy, beef, and plant-based origins. Alarmingly, more than two-thirds of these products contained lead amounts surpassing the safety threshold, set at approximately 0.5 micrograms per day.
Significant Findings from the Investigation
Brian Ronholm, the director of food policy at Consumer Reports, emphasized the growing popularity of protein supplements. He noted that these products have permeated daily routines for many consumers focused on increasing protein intake. The report outlines that the contamination of protein supplements with heavy metals is widespread and has deteriorated since their last assessment 15 years ago.
Lead Levels in Different Protein Sources
The analysis indicated that plant-based protein products contained the highest lead levels. In fact, the concentration of lead in these supplements was about nine times that found in dairy-based proteins, such as whey, and twice that of beef-based options. Two specific products were highlighted as particularly concerning:
- Naked Nutrition’s Vegan Mass Gainer
- Huel’s Black Edition
These items were classified as “products to avoid” due to their high lead content. Despite this, Huel asserted that their ingredients undergo rigorous testing and that their formulations are compliant with international food safety standards.
Concerns Over Other Contaminants
In addition to lead, Consumer Reports uncovered that two of the tested products surpassed safety levels for cadmium, classified as a probable human carcinogen by the EPA. Furthermore, three products were found to contain inorganic arsenic, another recognized carcinogen.
Call for Regulatory Action
It is important to note that the Food and Drug Administration (FDA) does not evaluate supplements like protein powders prior to sale, unlike regulated pharmaceuticals. In light of these findings, Consumer Reports has initiated a petition urging the FDA to impose stricter regulations on lead levels in protein products. Ronholm stated that consumers should not have to worry about harmful substances in their protein shakes.
This report underscores the necessity for enhanced oversight in the dietary supplement industry to ensure public safety. Earlier this year, the FDA set guidelines for lead in processed baby foods, marking a step towards greater regulation that could potentially extend to protein supplements in the future.
