    Key actives per serving

  • Methylcobalamin (active B12) — 500 mcg
  • L-5-MTHF Quatrefolic (active folate) — 680 mcg DFE
  • P-5-P (active B6) — 12 mg
  • Benfotiamine (fat-soluble B1) — 25 mg

The formula brief

Why this and why this dose.

B-vitamins are cofactors in mitochondrial energy metabolism — every molecule of ATP your cells produce passes through a B-vitamin-dependent enzyme. Cheap multis use the inactive forms (cyanocobalamin, folic acid) that require liver conversion. The active forms (methylcobalamin, methylfolate) skip that step entirely.

Roughly 40% of the US population carries an MTHFR gene variant that reduces methylfolate conversion efficiency by 30-70%. For these individuals, supplementing with folic acid actually accumulates unmetabolized folic acid in serum without raising functional methylfolate. The active forms bypass this entirely.

One capsule with breakfast covers it. Don't take this at night — for most people the B-complex is mildly stimulating.

01 · The protocol

How to take it.

  • Take 1 capsule with breakfast — avoid evening dosing (mildly stimulating).
  • Pair with the Multivitamin only if you specifically need higher methylated B-dose.

02 · Why this form

Form & sourcing.

Folic acid is a synthetic compound that requires liver conversion to functional methylfolate via DHFR and MTHFR enzymes. ~40% of the population has reduced MTHFR activity. L-5-MTHF skips both enzymatic steps.

03 · Stack it
