Scientists use special tools like nuclear magnetic resonance and infrared spectroscopy to check for these mixes. These tests help make sure you get pure cod liver oil.
Fish oil and krill oil can have impurities from the ocean, like heavy metals or chemicals. Makers use molecular distillation to clean the oil. This process removes things like mercury and dioxins. Nitrogen flushing keeps the oil fresh and stops it from going bad. Using low heat during distillation protects the omega-3 and keeps it safe for you.
"Twinlabs fish oil products are all molecularly distilled and quality tested for purity. These processes are especially effective for reducing impurities such as PCBs found in oceans, lakes, rivers and streams and common to fish and fish-based products."
