5-MTHF vs Folic Acid: Which Folate Is in SciatiEase?
5-MTHF vs folic acid is a choice between two folate forms. 5-MTHF (L-methylfolate) is at least as bioavailable as folic acid, per the NIH, and SciatiEase prints 500 mcg DFE of it. The bigger caution is B12: large folate intakes can correct anemia without fixing nerve damage from low B12.

Two forms01
What is the difference between 5-MTHF and folic acid?
Folic acid is the synthetic form. 5-MTHF is the form already in the blood.
The NIH says 5-MTHF (L-methylfolate) is at least as bioavailable as folic acid, though it has no formal DFE conversion. For labels, 1 mcg of folic acid counts as about 1.7 mcg DFE (NIH ODS, Folate).
SciatiEase prints folate (5-methyltetrahydrofolate) at 500 mcg DFE, which is 120% of the Daily Value.
Numbers02
How does 500 mcg DFE compare with the limits?
It is above the RDA and below the limit for synthetic folate.
| Item | Amount |
|---|---|
| Adult RDA (NIH ODS, Folate) | 400 mcg DFE |
| Upper limit, synthetic folate (NIH ODS, Folate) | 1,000 mcg |
| SciatiEase, 4 capsules | 500 mcg DFE |
That 1,000 mcg limit is for synthetic folate from supplements and fortified foods (NIH ODS, Folate). Whether 5-MTHF counts the same way has no formal rule in the fact sheet.
The catch03
Why does folate matter if your B12 is low?
Folate can hide the anemia of B12 deficiency while the nerve damage goes on.
Large folate intakes can correct the anemia but not the nerve damage, which raised concern about masking (NIH ODS, Folate). Low B12 can cause numbness and tingling, sometimes without anemia (NIH ODS, Vitamin B12).
If you have tingling feet or hands, ask for a B12 level before assuming a nerve formula is the answer.

Who should ask before taking extra folate?
People on methotrexate, and anyone with possible low B12.
People on methotrexate for cancer should ask their oncologist before taking folate (NIH ODS, Folate). Keep taking prescribed medicine and never change it because of a supplement.
See B12 deficiency nerve symptoms and riboflavin 5 phosphate for the other B lines. The B6, B2 and folate page details the panel.
FAQ05
Folate forms: specific questions
Is 5-MTHF better than folic acid?
The NIH says it is at least as bioavailable (NIH ODS, Folate), not clearly better. We found no trial showing a nerve-pain edge.
What does DFE mean on a label?
It means dietary folate equivalents. For labels, 1 mcg of folic acid counts as about 1.7 mcg DFE (NIH ODS, Folate).
Can folate hide a B12 deficiency?
Yes. Large folate intakes can fix the anemia but not the nerve damage (NIH ODS, Folate). A B12 blood test is the check.
How much folate is in SciatiEase?
One 4-capsule serving holds 500 mcg DFE of 5-methyltetrahydrofolate, 120% of the Daily Value. Two capsules hold 250 mcg.
Should methotrexate users take folate?
Ask your oncologist first (NIH ODS, Folate). Do not stop or change any prescribed medicine on your own.
