What is the recommended daily requirement of folate for adults?

The recommended daily requirement of folate for adults is 0.4 mg (400 micrograms). Folate, also known as vitamin B9, plays a critical role in DNA synthesis, repair, and methylation, as well as in the production of red blood cells. Adequate intake of folate is especially important for women of childbearing age, as it can help prevent neural tube defects during pregnancy.

In the context of dietary recommendations, the 0.4 mg figure is based on sufficient evidence to support optimal health and reduce the risk of specific deficiencies that could lead to anemia and other health issues. This recommendation reflects the balance needed to maintain good health while considering typical dietary patterns and bioavailability of folate from food sources.
