Best Methylfolate (5-MTHF) Supplements 2026
Methylfolate (5-methyltetrahydrofolate or 5-MTHF) is the biologically active, pre-converted form of folate (vitamin B9). Unlike folic acid, methylfolate does not require MTHFR enzyme conversion to become bioavailable. It is essential for DNA methylation, neurotransmitter synthesis (serotonin, dopamine), and homocysteine metabolism. Critical for individuals with MTHFR gene variants.
Key benefits
- Bypasses MTHFR mutation barriers
- Neurotransmitter synthesis (serotonin, dopamine)
- Homocysteine reduction (cardiovascular risk)
- Pregnancy neural tube defect prevention
- Mood and mental health support
