The European Food Safety Authority (EFSA) has concluded that the supplement Quatrefolic® is safe for human consumption and may be added for nutritional purposes to food supplements as a source of folate—an ingredient purported to reduce the risk of neural tube defects in infants. Derived from methyltetrahydrofolate and glucosamine salt, Quatrefolic® evidently features high water solubility, improved bioavailability, long-lasting stability, established safety, and higher formulation flexibility, and can overcome existing limits of previous methyl derivative reduced folates. It was approved as a New Dietary Ingredient by the U.S. Food and Drug Administration in 2010. See Gnosis Group News Release, October 3, 2013; newhope360, October 4, 2013.
