Protein powders may contain high levels of lead and cadmium, with chocolate-flavored and plant-based products testing at the highest levels, a new report said.
Over-the-counter protein powders may contain disturbing levels of lead and cadmium, with the highest amounts found in plant-based, organic and chocolate-flavored products, according to a new investigation. There is no level of lead that is safe for humans, according to the US Environmental Protection Agency.
The brands were not disclosed in the report, however. “We do not disclose the names of companies we test in order to maintain fairness and consistency and to avoid potential conflicts of interest,” Bowen said. Protein powder samples were then sent to an independent certified laboratory, which ran nearly 36,000 individual tests on 258 different contaminants, including heavy metals, bisphenols, phthalates and perfluoroalkyl and polyfluoroalkyl substances, or PFAS.

Tool Developed to Speed Up Protein Interaction Measurement for Drug DiscoveryScientists have created a publicly accessible software and web database to facilitate the identification of crucial protein-protein interactions for pharmaceutical treatments. This computational tool, named ConPLex, can predict whether potential drug molecules will interact with specific protein targets, eliminating the need for computationally expensive calculations. Additionally, bioengineers have developed a technology called PROPER-seq capable of revealing protein-protein interactions among thousands of proteins within a cell in a single experiment. Researchers are also employing deep learning to better understand protein interactions, aiming to generate accurate structural models.
