Tetrahydrofolic acid (THF) is the proper biologically active form of the folates and acts as a coenzyme. Folate coenzymes play an important role in the metabolism of several amino acids, the building blocks of proteins. Due to the missing scientific studies into the natural B vitamins, the decision as to which active ingredient to opt for must be based on personal feelings and common sense. the B-vitamin most easily destroyed by exposure to light is. Due to the missing scientific studies into the natural B vitamins, the decision as to which active ingredient to opt for must be based on personal feelings and common sense. Overview Information Folate and folic acid are forms of a water-soluble B vitamin. One-carbon derivatives of tetrahydrofolate, the coenzyme form of the vitamin folic acid, play a key role in DNA synthesis and cell replication, through their involvement in the biosynthesis of purine nucleotides and the amino acids.

The mission, to "advance science, engineering, and innovation throughout the world for the benefit of all people," has propelled the organization to the forefront of national and international initiatives. Folate. In this regard, over the last five years HPDI has eliminated folic acid from all of the multivitamins and B-Complex vitamins that we now make available. 3. Folate is a generic term referring to both natural folates in food and folic acid, the synthetic form used in supplements and fortified food. For this reason, taking additional folate as the coenzyme forms 5-MTHF and Folinic Acid will very likely offset the folic acid still found in many supplements - especially multivitamins and B-Complex formulas. F. M. Huennekens, M. J. Osborn and H. R. Whiteley, Published By: American Association for the Advancement of Science, New Series, Vol. Pediatr Res. Methionine and serine formation in control and mutant human cultured fibroblasts: evidence for methyl trapping and characterization of remethylation defects. Some dietary supplements also contain folate in the monoglutamyl form, 5-methyl-THF (also known as L-5- MTHF, 5-MTHF, L-methylfolate, and methylfolate). The distinction between food folate and folic acid is important because of differing bioavailability (ie, food folate is only about half as available as folic acid consumed on an empty stomach).
