Folinic Acid Lozenges by Seeking Health provide 1,360 mcg DFE (800 mcg) of pure, bioavailable folate as folinic acid calcium salt per lozenge. This form of folate (vitamin B9) quickly converts to L-methylfolate, the predominant form of folate in circulation in the body. Folate is essential for cell division, growth, and the formation of new red blood cells. Folinic acid can easily convert to any of the other active forms of folate as needed in the body.*
