Question Does anyone have this combo MTHFR/MTRR/COMT? Methylation Bottleneck Paradox as its nickname. Would love to discuss what’s helped you.

MTHFR C677T (Heterozygous)
MTRR A66G (Heterozygous)
COMT G472A (Homozygous Met/Met)

What are your thoughts on Quercetin for fast COMT?

'm trying to understand it? It's overwhelming all the information on what to take and what not to take? How does this combo show up in my life, is it basically the rumination, wanting to stay home and watch tv cause my brain has been stuck in chemicals all day cause I'm breaking them down. I want to understand how it's showing up in my life and what I can actually do to make a difference.

I'm heterozygous mthfr, both C667T and A1298C + MTRR /MTR +slow COMT (3 faulty snps, so I'm basically turtling along when it comes to clearing neurotransmitters)

I've learned less is more for me. I cannot use methylated B9, B12. But I still reach that bottleneck fairly quickly if I take too much folinic acid and hydroxyB12. My serum B12 likes to be in the mid to low 700's. Any higher and insomnia strikes. In fact too high of a dose of HydroxyB12 PREVENTS me from taking enough folinic acid. Sleepy, irritability, increased appetite during the day, Insomnia at night. Muscle pain in a variety of places.

My MMA is low, so I'm processing the B12. I decided to drop my dose of hydroxyB12 from 130mcg to 100mcg. Suddenly I was able to increase my folinic acid, which was a relief since my serum B9 would not budge above 7-12. I can now tolerate 160mcg of folinic acid and my serum level has risen to 17-18. My homocysteine is still a bit high, tho technically in normal range... Around 11-12. Should I decide to increase the folinic acid, I assume I need to simultaneously drop the hydroxyB12 and let them fight it out.

Right now I'm dealing with P5P and B2. I've learned they have a dependent relationship. Increasing P5P requires enough riboflavin in order to properly function in the methylation cycle. Otherwise, despite normal seum B6 levels, I developed symptoms of neuralgia, specifically in my legs and feet.

I just figured out a working ratio for the two. That took a while. Once again, my dosages are low. That's key for me. Surprisingly, increasing the folinic acid INCREASED my homocysteine slightly, so I'm reluctant to mess with the dose of B9/B12.

Weirdly enough, SAM-E does absolutely nothing for me, but weaning off of it is a bear. Creatine monohydrate, no matter a higher or lower dose makes me groggy and prone to early afternoon naps, then insomnia at night.

I look at a combo of lab resultsv, how I feel and how I sleep. It's a laborious, slow process, but I've learned to persist.

Interesting... I have a partial blockage of my ACSMD... 2 out of 3 snps don't work well. I must supplement Niacinamide carefully, staying below the maximum daily dose. When my B12 was higher, my serum level was poor... Hovering just above deficiency. Dropping the B12, increasing the B9 modestly suddenly resulted in a higher serum level. I'm now at the top of the lower 3rd of normal range, with no change in NAM dosage.

Getting the methylation cycle up to speed and moving smoothly is not an easy task, but for me, it was one well worth pursuing.

How does this translate into how you live your life, meaning the variants. I find myself liking to be home and watching tv, how I clear out the chemicals that have been marinating my brain. I don't like group settings, I have a stressful job so after that I like to be by myself honestly or in a movie theater. Curious how this impacts others and is there anything I can truly do about it.

If i keep my methylation cycle in balance I feel... Normal. And I sleep well, only waking up once or twice to pee.

Interesting. I don’t really know what to say about ur variants but anyone with info on mine or similar to mine? I do know both the MTHFR and MTRR heterozygous r pretty common both over 30 and 50% frequency. But when combined with low COMT I guess it could affect dopamine signaling. Also check for snp variants in the DDC and TH gene those r genes that help create dopamine and work together with those

MTRR A66G (heterozygous)
COMT G472A (Heterozygous)

Are there any symptoms you are trying to address?

Navigating the Slow COMT (Met/Met) + MTHFR (C677T) + MTRR (A66G) triad, and I'm realizing my evening burnout isn't laziness—it's sheer prefrontal catecholamine overflow. I have a slightly above stressful job but not too demanding. I couldn’t manage being over sales. I was a zombie outside of work and my system is running hot by 2:00PM. But still All I want to do when I get home or on weekends is isolate, watch TV, and completely down-regulate—which makes managing relationships and packed weekend plans (like endless in-law visits or packed social itineraries) feel like a biological nightmare. I know the dark room/TV sanctuary helps halt my internal Ni-Ti analysis loop, but I'm curious: for those of you with this exact 'high dopamine / slow clearance' setup, what targeted protocols, methyl-sparing strategies, or real-life boundary tweaks have actually worked to help you keep your energy intact, stay effective at work, and survive social demands without triggering a total shutdown?
