Dose & timing
- ½ pill — Mon & Thu — ½ pill 2×/wk
Why it’s in the stack
Methylated B-complex (B6 as P5P, B9 as methylfolate, B12 as methylcobalamin) — the bioactive forms required by the ~10–15% of people with MTHFR polymorphisms who can't efficiently convert folic acid. Half-pill twice weekly avoids the supraphysiological doses common to standard B-complex tablets.
