Methylation & Methylated B-Vitamins (MTHFR)
Brecka's signature topic: if you carry MTHFR variants, use the active (methylated) B-vitamins so your body can actually use them, and skip synthetic folic acid.
The biology is real: the MTHFR gene helps convert folate into its usable form, and common variants can slow that enzyme. Brecka's fix is to skip the conversion step by taking the active forms directly: methylfolate (5-MTHF) instead of folic acid, and methylcobalamin instead of cyanocobalamin, often with TMG as a methyl donor. The honest caveat is that MTHFR's clinical significance is frequently overstated: reviews have found routine MTHFR screening lacks clear clinical utility for most people. The low-risk version is simple, because a methylated B-complex is a benign supplement you do not need a gene test to take.
Why it works▼
Test methylation genes
Knowing your variants can guide whether targeted supplementation is worthwhile.
Take a methylated B-complex
The active forms bypass the conversion step that MTHFR variants slow down.
Add TMG (betaine)
TMG supports the methylation cycle alongside the B-vitamins.
Cut synthetic folic acid where practical
Some people process synthetic folic acid poorly; whole-food folate and methylfolate are cleaner options.
- People with known MTHFR variants
- Anyone with fatigue or low mood exploring foundational nutrition
- Those who prefer active-form vitamins
- MTHFR is real, but its clinical significance is often overstated. Reviews have found routine MTHFR screening lacks clear clinical utility for most people
- Brecka's own 10X Health genetic methylation test (around $599) makes disease-risk and biological-age claims that independent reviewers consider overstated, and he has an economic interest in it. The test is optional; a methylated B-complex is benign and needs no gene test
