14 Nov 2019 --- Researchers at dietary supplements manufacturing company NOW have developed an identification method testing for the presence of inorganic arsenic in krill oil. Although a natural element, arsenic compounds are potent poisons and are classified as a Group-A carcinogen. The NOW research team’s new method improves on Food Chemicals Codex’s (FCC) monograph from 2017 and contributes to a more accurate risk assessment analysis regarding consumption of krill oil supplements.
