According to the Clean Label Project, a consumer group that tested popular collagen supplements, 34% contained trace levels of mercury. Given environmental pollution, the potential for contamination in marine-sourced products like fish collagen is a real concern, making it vital to understand the risks and how manufacturers ensure product purity.

According to the EPA, virtually all fish and shellfish contain traces of mercury, a naturally occurring element that is also a byproduct of industrial processes. However, mercury is just one of several types of contaminants in fish that can affect human health. Understanding what these pollutants are, how they get into our food, and how to reduce exposure is key to making informed dietary choices.

According to a 2023 study by the Environmental Working Group (EWG), freshwater fish caught in the United States contain significantly higher levels of "forever chemicals" (PFAS) than commercially caught saltwater fish. However, determining if saltwater fish are safer than their freshwater counterparts requires a closer look at several key factors, including pollutants, bacteria, and parasites, which all pose unique risks depending on the specific fish and its environment.
