Do You Have Genetic Anxiety? 𧬠Slow COMT, Dopamine & Overthinking
Could your COMT gene influence how you respond to stress, worry, stimulants, and everyday mental pressure?
If you constantly feel anxious, overstimulated, restless, on edge, or stuck in your thoughts, despite trying therapy, lifestyle changes, or other approaches, there may be another piece of the puzzle worth understanding.
How quickly your body breaks down dopamine and norepinephrine.
The COMT (catechol-O-methyltransferase) enzyme helps metabolize catecholamines including dopamine, epinephrine, and norepinephrine.
One commonly discussed COMT variant is Val158Met (rs4680).
People with the Met/Met genotype generally have lower COMT activity than Val/Val, meaning certain catecholamines can remain available for longer in the prefrontal cortex, where dopamine regulation is important for cognition, attention, and stress processing.
That doesn't mean Slow COMT = anxiety.
But genetics may help explain why some people seem to be more sensitive to stress, caffeine, stimulants, sleep deprivation, hormonal changes, or excessive mental stimulation. And here's where nutrition gets interesting.
COMT requires SAM (S-adenosylmethionine) as its methyl donor, connecting catecholamine metabolism to methylation, folate, B12, magnesium, and overall nutritional status.
So could your genetics be influencing how you experience anxiety, stress, motivation, focus, and overstimulation?
