A GRAS ("Generally Recognized As Safe") assessment of the indepth safety and toxicity information was performed by an Independent Expert Panel. The Panel concluded that Quatrefolic® is GRAS for the proposed uses of a food ingredient as required by the Food & Drug Administration.

Quatrefolic® has been rigorously tested for safety and consistency. It is produced under strict quality control procedures allowing Gnosis to promote the product for application in a variety of conventional foods, beverages and supplements.

After a deep review of the extensive safety information and the uniqueness of the Quatrefolic® compound, FDA has accepted the New Dietary Ingredient (NDI) notification for the ingredient concluding that a dietary supplement containing the new dietary ingredient is expected to be safe under the conditions of use recommended or suggested on the label.

The term "new dietary ingredient" means a dietary ingredient that was not marketed in the United States in a dietary supplement before October 15, 1994.

The NDI notification is a complex procedure. More than 80% of NDI notifications are rejected by the FDA due to insufficient evidence for safety, the absence of required elements, as well as incomplete document submitted.

The European Food Safety Authority (EFSA) has adopted a positive scientific opinion after a thorough assessment of the safety data and bioavailability studies, a process that has lasted for nearly two years and a half, concluding that Quatrefolic® may be added for nutritional purposes to food supplements as a source of folate.

The positive scientific opinion has been forwarded to the European Commission for releasing Novel Food authorization and subsequent amending of Food Supplements Directive 2002/46/EC.
