Heavy, Man

If your daily health regimen includes a dose of collagen supplement, beware. 

Despite labeling claims such as “Pure,” “All-Natural” and “Cleanest Nutrition Possible,” and deceiving images of grazing cows, open pastures and cage-free chickens on packaging and websites, most collagen peptide supplements are derived from industrial factory farms—and many collagen products contain heavy metals.

Organic Consumers Association and Clean Label Project tested 28 of the top-selling brands of collagen supplements on Amazon.com. Here’s what we found:

• 64% tested positive for measurable levels of arsenic
• 37% tested positive for measurable levels of lead
• 34% tested positive for trace levels of mercury
• 17% tested positive for measurable levels of cadmium

Why should consumers be concerned about these findings?

Because heavy metals accumulate over time in the body’s tissues, which can potentially lead to organ damage and in some cases, cancer.
