levomefolate calcium and its Impurities
Levomefolic acid is the metabolite of folic acid and it is a predominant active form of folate found in foods and in the blood circulation. It is available commercially as a crystalline form of the calcium salt, which has the stability required for use as a supplement. Reference standards of Levomefolate Calcium API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
