Folate, or vitamin B9, is an important micronutrient that plays a key role in many aspects of health, including DNA synthesis, red blood cell formation, and fetal Plasma homocysteine concentration is a commonly used functional indicator of folate status because homocysteine levels rise when the body cannot convert homocysteine to methionine due to a 5-MTHF deficiency [9].
