Asam folat (dikenal juga sebagai Vitamin B9 atau Folacin) dan Folat (dalam bentuk alamiahnya) adalah vitamin B9 yang dapat larut di air. Vitamin B9 sangat penting untuk berbagai fungsi tubuh mulai dari sintesis nukleotid ke remetilisasi homocysteine. Vitamin ini terutama penting pada period pembelahan dan pertumbuhan sel. Anak-anak dan orang dewasa memerlukan Asam Folat untuk memproduksi sell darah merah dan mencegah anemia. Folat dan asam folat mendapatkan namanya dari kata latin folium (daun)

Vitamin B9 (Folic acid and Folate inclusive) is essential to numerous bodily functions ranging from nucleotide synthesis to the remethylation of [[homocysteine]]. It is especially important during periods of rapid cell division and growth. Both children and adults require folic acid to produce healthy red blood cells and prevent anemia.<ref>Dietary Supplement Fact Sheet: Folate. Office of Dietary Supplements, National Institutes of Health. http://ods.od.nih.gov/factsheets/folate.asp</ref> Folate and Folic acid derive their names from the Latin word ''folium'' (leaf).
==Folate in foods and other sources==
[[Leafy vegetable]]s such as [[spinach]], [[turnip|turnip greens]], [[lettuce]]s, dried [[bean]]s and [[pea]]s, fortified [[cereal]] products, [[sunflower seed]]s and certain other [[fruit]]s and [[vegetable]]s are rich sources of folate. [[Liver]] and liver products also contain high amounts of folate, as does [[baker's yeast]]. Some [[breakfast cereal]]s (ready-to-eat and others) are fortified with 25% to 100% of the [[recommended dietary allowance]] (RDA) for folic acid. A table of selected food sources of folate and folic acid can be found at the USDA National Nutrient Database for Standard Reference.<ref name = USDA>{{cite web

J Am Coll Nutr 24, 266-274.</ref>. Because of the difference in bioavailability between supplemented folic acid and the different forms of folate found in food, the dietary folate equivalent (DFE) system was established. 1 DFE is defined as 1 μg of dietary folate, or 0.6 μg of folic acid supplement. This is reduced to 0.5 μg of folic acid if the supplement is taken on an empty stomach.<ref>Suitor CW & Bailey LB (2000) Dietary folate equivalents: interpretation and application.
