Short answer

Take it with other B vitamins (B12, B6) for methylation support, with or without food. A daily B-complex or good multivitamin is preferred over folate alone (Mark Hyman).

Full Protocol

Timing
Take it with other B vitamins (B12, B6) for methylation support, with or without food. A daily B-complex or good multivitamin is preferred over folate alone (Mark Hyman).
Dosage
400-1,000 mcg daily of methylfolate (5-MTHF), not synthetic folic acid. People with homozygous MTHFR variants or high homocysteine may need more, under medical supervision. In one stack the dose is guided by homocysteine levels (Peter Attia).
Form
Methylfolate (5-MTHF or L-methylfolate) is preferred over synthetic folic acid wherever a form is named. Folic acid needs an enzyme step that MTHFR carriers do poorly. Look for 'methylfolate,' '5-MTHF' or 'L-5-methyltetrahydrofolate' on labels.
Notes
Test homocysteine before you start to set a baseline; one target is below 9 (Peter Attia). Consider genetic testing (23andMe or similar) for MTHFR variants. Pair methylfolate with methylcobalamin (methyl-B12), because they work together in the methylation cycle. Folate-rich foods include dark leafy greens (spinach, kale), legumes and cruciferous vegetables.

    DISCUSSION Interpretation of the Findings This study's major findings indicated that a dose of approximately 800 μg of FA, when combined with vitamin B 6 and B 12 , is more effective than other combinations in reducing Hcy levels in healthy adults.

  2. Pooled analysis, Stroke, 2010, PMID 20413740 Study · partly

    The RR for trials using folic acid plus vitamins B12 and B6 was 0.83 (95% CI 0.71-0.97; p=0.02) while trials using folic acid alone or folic acid plus vitamin B12 did not show any RR change.
