Folinic Acid Supplements
There are two main forms of vitamin B9. Natural folates and man-made folic acid. Seeking Health does not use folic acid in any of our products as it is not bioavailable and must be converted to a different form before the human body can use it for methylation.†
Folinic Acid is a natural form of folate that is highly bioavailable for our customers who are more sensitive to pre-methylated nutrients like 5-MTHF.†

If you have MTHFR or other SNPs that affect methylation, you know how crucial bioavailable nutrients are. But if you are sensitive to methylated nutrients like L-methylfolate, you can still get a usable form of folate (vitamin B9).†
It’s called folinic acid, and unlike folic acid supplements, it readily converts to active folate in the body. Folinic acid complements your dietary folate intake and supports healthy folate levels. Getting enough folate is vital for many reasons, including the maintenance of healthy homocysteine levels, nervous system, and red blood cells. It is also vital for pregnant women in early pregnancy.†
Folinic acid does not produce the same jittery or overwhelming symptoms that certain sensitive individuals may experience from L-5MTHF (L-methylfolate).†
Explore Seeking Health’s folinic acid dietary supplements below. Get started with the top-selling Folinic Acid Lozenge, a bioavailable form of folate that provides 1,360 mcg DFE (800 mcg) of folinic acid calcium salt. Pair your Folinic Acid Lozenge with B Minus or Multivitamin Sensitive, and a methyl-free form or B12 (like hydroxocobalamin) for your complete B complex nutrients. For a multivitamin that contains folinic acid, consider Optimal Prenatal MF.†
