COMT: Why Some Brains Are Ferraris and Others Need a Minute

---

If MTHFR gets all the internet attention, COMT is the gene quietly running background operations like an exhausted office manager.

COMT stands for Catechol-O-methyltransferase.
Very catchy name. Definitely should have hired a branding team.

Its job is to help break down certain neurotransmitters and stress hormones, including:

• Dopamine 
• Norepinephrine 
• Epinephrine (adrenaline) 

Basically, COMT helps regulate how long your brain hangs onto stimulation, stress, emotions, motivation, and mental energy.

COMT may influence things like:

• Stress tolerance 
• Mental “busyness” 
• Emotional sensitivity 
• Focus and motivation 
• Processing speed 
• Anxiety tendencies 
• Sleep 
• Response to stimulants and stress 

Fast COMT (Val/Val)

AKA:

• “The brain that clears dopamine quickly” 

These individuals often:

• Handle stress better in the moment 
• Move on from emotions faster 
• Think quickly under pressure 
• Need more stimulation to stay focused 
• Sometimes feel under-stimulated or “blah” 

The downside?
Their brains may burn through dopamine a little too fast.

Think:

“Why am I bored 11 seconds after starting this task?”
 

AKA:

• “The brain that hangs onto dopamine longer” 

These individuals often:

• Feel emotions deeply 
• Notice everything 
• Overthink conversations from 2009 
• Have strong empathy and creativity 
• Get mentally overstimulated more easily 

The downside?
Stress hormones may linger longer too.

Think:

“My brain has opened 47 tabs and refuses to close any of them.”
 

Honestly? No.

Fast COMT is not “good.”
Slow COMT is not “bad.”

Each comes with strengths and trade-offs.

Some people thrive under pressure.
Others thrive in calmer environments with more recovery time.

Your brain is basically trying to optimize itself with the operating system it was handed.

COMT may help explain why some people:

• Feel extremely sensitive to stress 
• Respond differently to stimulants 
• Become overstimulated by caffeine 
• Experience anxiety more intensely 
• Feel emotionally “too much” 
• Burn out quickly 
• Struggle with racing thoughts 

It may also influence how some individuals tolerate:

• ADHD medications 
• L-methylfolate 
• Stress 
• Sleep deprivation 
• Hormonal shifts 

Genes are not destiny.

COMT is one small piece of a much larger picture that includes:

• Sleep 
• Nutrition 
• Hormones 
• Trauma 
• Lifestyle 
• Medical conditions 
• Therapy 
• Stress levels 
• Overall nervous system health 

The goal is not to “fix” your genetics.
The goal is understanding your brain a little better so you can work with it instead of constantly fighting it.

Some brains are:

• Calm under pressure 
• Quick to recover 
• Efficient stress processors 

Other brains are:

• Deep thinkers 
• Highly sensitive 
• Creative 
• Emotionally intense 
• Chronically running internal TED Talks 

Both are still valid operating systems.
