Frequently asked questions
- What is 'methyl' folate?
- 5-methyltetrahydrofolate (5-MTHF) is the metabolically active form of folate (vitamin B9). People with MTHFR enzyme variants don't convert folic acid efficiently and sometimes choose 5-MTHF for that reason.
- Where is it sold?
- Amazon UK at £16.15 is the listed retailer.
- Is the IGEN cert a banned-substance test?
- No — IGEN Non-GMO Tested verifies non-GMO sourcing only.
- Is 400mcg a standard daily dose?
- 400mcg matches the standard recommended daily folate intake for adults. Pregnancy generally requires more — discuss with a GP for pregnancy-specific dosing.
- How does methyl folate compare to folic acid?
- Same end goal (raising folate status). Folic acid is the cheaper, synthetic form; 5-MTHF is the active form, useful if folic-acid conversion is impaired. For most healthy adults, folic acid is sufficient.
