Your pre-workout and protein supplements may contain hidden heavy metals that nobody told you about.
What Testing Revealed
A 2026 study in J Trace Elem Med Biol tested sports nutritional supplements for trace and heavy elements and ran health risk evaluations. They found metals at levels that warrant concern for regular consumers. Athletes who take these supplements daily are getting repeated doses.
The supplements tested included products marketed for muscle building, recovery, and performance. The heavy metals detected can damage kidneys, liver, bones, and the nervous system over time.
What You Can Do
Choose supplements with third-party testing certifications. Get protein from whole food sources when possible. Don't assume expensive means clean. Browse non-toxic home essentials for safer product options.
