The MTHFR Stack

Methylfolate and methylcobalamin regenerate SAMe through the methionine cycle. SAMe then donates methyl groups to DNA, neurotransmitters, phospholipids, and detoxification pathways.

MB12
Methylcobalamin (5,000mcg) + methylfolate (1,000mcg) in their final bioactive forms, completely bypassing MTHFR enzyme conversion.

SAMe
SAMe (S-adenosylmethionine), the universal methyl donor.

OptiBoost Multi
Fully methylated multivitamin with active B2 (riboflavin-5-phosphate), B6 (P5P), chelated minerals, and R-lipoic acid.

✓ Who this is for

People who have tested positive for MTHFR C677T or A1298C gene variations. People with elevated homocysteine who want to support healthy methylation through nutrition.

✗ Who this is not for

People currently taking SSRIs, SNRIs, MAOIs, or tramadol - SAMe increases serotonin and combining it with serotonergic medications raises the risk of serotonin syndrome; this is the most important contraindication for this bundle. People with COMT gene variations who are sensitive to methyl donors (start at lower doses).

Morning with breakfast: MB12 (1 sublingual tablet for direct absorption), SAMe (2 capsules on an empty stomach or with a light meal), and OptiBoost Multi (4 capsules with food). SAMe is most effective when taken in the morning, as it supports energy and mood.

Energy and mood improvements: 2-4 weeks. Homocysteine reduction (if elevated): 4-8 weeks (confirm with blood work).

What supplements should I take for MTHFR gene variations?

The core of an MTHFR protocol is methylcobalamin, methylfolate, and SAMe. Methylcobalamin and methylfolate are the final bioactive forms of B12 and folate - they require no conversion by the MTHFR enzyme.

What does SAMe actually do?

SAMe (S-adenosylmethionine) is the molecule that donates methyl groups to over 200 biochemical reactions, including neurotransmitter synthesis, DNA methylation, phospholipid production, and detoxification. B12 and methylfolate regenerate SAMe through the methionine cycle.

Can methylated B vitamins cause anxiety?

Some people with COMT gene variations process methyl groups slowly. For them, high-dose methylated B vitamins and SAMe can temporarily raise catecholamine levels - dopamine and norepinephrine - which may feel like anxiety or restlessness.

SAMe should not be combined with SSRIs, SNRIs, MAOIs, tramadol, or other serotonergic medications due to risk of serotonin syndrome. SAMe may trigger mania in people with bipolar disorder.
