Kirkman® offers Folinic Acid hypoallergenic capsules for individuals with special requirements and sensitivities. Biochemically in the body, folic acid supports cellular perception and response, methylation processes and many enzymatic reactions. It is also linked to maintaining healthy homocysteine levels, which supports cardiovascular health. To be active in the body, folic acid has to be reduced twice by folate reductase enzymes, then converted to tetrahydrofolate, after which a methyl group is added to the tetrahydrofolate. In some individuals, the use of natural folinic acid may be more beneficial than folic acid, because folinic acid already has attached four hydrogen and one methyl group, thereby shortcutting the complicated biochemical process.
