• Detailed Description:

  Cas No. :151533-22-1 Calcium L-5-methyltetrahydrofolate
  CAS: 151533-22-1
  
  It is the calcium salt of L-5-methyltetrahydrofolic acid [1], which is the predominant, naturally occurring form of folate.
  
  Commercial use of Calcium L-5-methyltetrahydrofolate in pharmaceutical products began in Europe in the early part of this decade. This approach to folate supplementation has potential to impact prenatal care, homocysteine management, and the treatment of depression, dementia and cardiovascular concerns.
