Popular Protein Powders Contain Alarming Levels of Lead, New Study Finds

A new investigation has uncovered dangerous levels of heavy metals in popular protein supplements. Consumer Reports tested 23 leading protein powders and ready-to-drink shakes. The findings reveal widespread lead contamination.

More than two-thirds of the tested products contained more lead per serving than is considered safe for daily consumption. This raises significant health concerns for regular users of these fitness supplements.

Plant-Based Proteins Show Highest Contamination Levels

The testing data revealed a clear pattern. Plant-based protein products were the most contaminated. They contained, on average, nine times more lead than dairy-based proteins like whey.

Some products had shockingly high concentrations. Naked Nutrition Vegan Mass Gainer contained 7.7 micrograms of lead per serving. Huel Black Edition and Garden of Life products also showed high levels. Consumer Reports experts advise against daily use of most powders.

Long-Term Health Risks Prompt Consumer Warning

Lead exposure poses serious long-term health risks. It can affect the nervous system and cardiovascular health. There is no safe level of lead exposure for children.

For adults, consistent low-level exposure is dangerous. Tunde Akinleye, the lead researcher, noted lead levels are higher now than in tests from 15 years ago. He advises regular users to consider reducing their intake immediately.

The discovery of high lead levels in everyday protein supplements is a major public health concern. Consumers should reassess their reliance on these products for daily nutrition and seek safer protein sources.
