Formulation Notes

Nutrition information: Folic acid, which is also known as vitamin B9, supports cellular energy production in the body. Everyone needs folic acid, but it's particularly important for women of childbearing age because folic acid plays a critical role in the proper development of a baby's nervous system. Adequate folic acid in healthful diets may reduce a woman's risk of having a child with a neural tube defect.
