Folate
Folate, also known as vitamin B9, is a water‑soluble B vitamin essential for one‑carbon metabolism, nucleotide biosynthesis, and remethylation of homocysteine. Naturally occurring in foods as polyglutamates and added to foods or supplements as folic acid, adequate folate status is critical for cell division and early embryonic neural tube closure and is a cornerstone of public health fortification and periconceptional supplementation policies.
