Food Supplement based on Folic Acid and Phosphatidylcholine. Our body converts folate from food into a special form of folate with a methyl group. This “active” methylated folate is known as 5-methyltetrahydrofolate (5-MTHF). An important enzyme called MTHFR is needed to carry out the final critical step of producing 5-MTHF. Among other things, folates help reduce the risk of neural tube defects and other birth defects. Instructions for use: Take 1 capsule, at any time of the day, with half a glass of water (approximately 75ml).
