Folic acid (Vitamin B9)(Vitamin M; Vitamin B9) is indispensable for the production and maintenance of new cells, for DNA/RNA synthesis.

Folate sodium, as a member of the vitamin B family, can stimulate the hematopoietic system. Folic acid can be used in the treatment and prevention of folate deficiencies and megaloblastic anemia.

Levomefolic Acid (5-MTHF) is a natural, active form of folic acid used at the cellular level for DNA reproduction, the cysteine cycle and the regulation of homocysteine among other functions. Levomefolinic acid is used as a treatment and to prevent Folate Deficiency

Folinic acid calcium (Leucovorin Calcium) is the active metabolite of folic acid. Leucovorin is used principally as an antidote to folic acid antagonists.

5-Methyltetrahydrofolic acid (5-Methyl THF) is a biologically active form of folic acid and a methylated derivate of tetrahydrofolate. It is the predominant natural dietary folate and the principal form of folate in plasma and cerebrospinal fluid.

Pteroic acid is part of the structure of folic acid

6R-Leucovorin is a derivative of Folic Acid.

Homocystine is the double-bonded form of homocysteine, but it occurs only transiently before being converted to the harmless cystathionine via a vitamin B6-dependent enzyme. Increasing evidence supports a role for an elevation of homocysteine in schizophr

Cyanocobalamin is a cobalt-containing coordination compound generated by intestinal microbes and a natural water-soluble vitamin of the B-complex family that must combine with Intrinsic Factor for absorption by the intestine. Cyanocobalamin is necessary for hematopoiesis, neural metabolism, DNA, and RNA production, and carbohydrate, fat, and protein metabolism. B12 improves iron functions in the metabolic cycle and assists folic acid in choline synthesis. B12 metabolism is interconnected with that of folic acid. Vitamin B12 (Cobalamin) deficiency causes pernicious anemia, megaloblastic anemia, and neurologic lesions.

Xanthopterin Hydrate is isolated from butterfly wings and could replace folic acid in the nutrition of many animal species.

Aminopterin (4-Aminofolic acid) is a synthetic folic acid derivative whose metabolite is a competitive inhibitor of dihydrofolate reductase

Pterine-6-carboxylic acid (6-Carboxypterin) is a photodegradation product of folic acid, which can be used as a photosensitive agent to study the molecular mechanism of UVA breaking DNA structure.

Dihydrofolic acid (7,8-Dihydrofolic acid) is a folic acid derivative that produces tetrahydrofolic acid in the presence of dihydrofolic acid reductase.
