Folic Acid History

  Folic Acid (CAS NO.59-30-3) was identified as the corrective substance in brewer's yeast in the late 1930s and was first isolated in spinach leaves by Mitchell and others in 1941.

Folic Acid Uses

 Folic Acid (CAS NO.59-30-3) is necessary for the production and maintenance of new cells, appears to reduce the risk of stroke. It is also added to grain products in many countries and in these countries fortified products make up a significant source of folate. It is an important nutrient for women who may become pregnant.
