This is one of the most important things to know on TRT.
Your body doesn’t delete estrogen. It dismantles it.
On TRT, aromatase converts a share of your testosterone into estradiol. That’s not a malfunction — you need estrogen for bone, brain, libido and joints. But more testosterone means more raw material.
What happens next matters more than the number on your lab report.
Your liver breaks estradiol into fragments called catechol estrogens (2-OH and 4-OH). Left unprocessed, the 4-OH fragment in particular can react further into quinones that generate oxidative stress and damage DNA. So your body has a second step: an enzyme called COMT clips a methyl group onto those fragments, turning them into inactive 2-MeO and 4-MeO estrogens that leave the body.
COMT can’t do that without a methyl donor. That donor is SAMe — and SAMe gets built when methylfolate (B9) carries a methyl group and methylcobalamin (B12) hands it off to homocysteine. Short on either and methylation capacity drops. Low B12 also creates the methylfolate trap: folate stuck in a form your body can’t use while homocysteine climbs. Common MTHFR variants make standard folic acid harder to convert — methylated forms skip that step.
Honest part: this is mechanism, not proof. There’s no randomized trial showing methylated B vitamins improve estrogen clearance on TRT. And they are not an aromatase inhibitor — they will not lower your estradiol number. They support how metabolites get processed, not how much estrogen you make.
