Bioaccumulation of heavy metals and other environmental contaminants in fish is a serious health concern. To ensure exceptional purity and safety, always purchase fish oil supplements that are third-party tested.
All fish oils are naturally prone to contamination from heavy metals and other environmental pollutants. For safe consumption, it is absolutely necessary to remove these harmful toxins from the fish oils. These harmful toxins include:
Heavy metals, such as mercury, arsenic, cadmium and lead that can damage the functioning of organs such as the brain, kidneys, lungs, liver, and blood. The symptoms of heavy metal poisoning may vary, depending on the types of heavy metal involved. In general, these symptoms include diarrhea, nausea, vomiting, abdominal pain, shortness of breath, chills, weakness or tingling in hands and feet.
Dioxins and furans are environmental contaminants, not processing-induced food contaminants. These are some of the most toxic chemicals known to science. Dioxins can damage the immune system, cause reproductive and developmental problems, interfere with hormones and cause cancer, while furans can cause liver toxicity and liver carcinogenicity
Polychlorinated biphenyls (PCBs) are highly toxic industrial compounds. These toxic chemicals can build up in the fatty tissues of fish. When consumed in higher concentrations, it can pose serious health risks to people who regularly consume contaminated fish. The prolonged or repeated exposure to small amount of PCBs could lead to developmental and neurological problems.
The Global Organization for EPA and DHA Omega-3s (GOED), The Council for Responsible Nutrition (CRN) and European Pharmacopoeia (Ph. Eur.) organisations have set a standard for fish oil purity. To ensure objective proof of the fish oil quality, it is very important to purchase fish oil supplements that are third-party tested or has a seal of purity from any of these organisations. These labels show that the standards are followed by fish oil manufacturers and hence, the fish oils are guaranteed safety and purity.
