Anxiety

Anxiety has many causes — psychological, hormonal, gut-related, nutritional. A specific genetic pattern worth knowing: slow-COMT carriers clear dopamine and norepinephrine more slowly under stress, and they can be paradoxically over-activated by common 'methylation support' supplements.

Key facts

Key gene	COMT (rs4680)
Often helps	Magnesium glycinate, L-theanine
Often worsens (in slow-COMT)	Methylfolate, methyl-B12

Genetic context

COMT rs4680 Met/Met (often called 'slow COMT') reduces enzyme activity to about 25% of the fast variant. These individuals tend to be more attentive at baseline but more easily overwhelmed under stress, and they accumulate catecholamines longer when activated.

Supplements worth considering

Magnesium glycinate 200-400 mg evening
L-theanine 100-200 mg as needed
Glycine 1-3 g at bedtime if anxiety affects sleep
Adequate B6 (P-5-P) to support GABA synthesis

What to be cautious with (slow-COMT)

L-methylfolate at higher doses — switch to folinic acid if you feel wired or irritable
Methylcobalamin — hydroxocobalamin is often better tolerated
Caffeine — slow-COMT carriers often metabolize and feel it for longer
Tyrosine, DLPA on top of stimulants

When to seek care

Anxiety that interferes with daily function, sleep or relationships deserves professional support. Genetic factors describe susceptibility; effective treatment usually combines therapy, lifestyle and (sometimes) medication.

FAQ

Why does methylfolate make me anxious?

Slow-COMT carriers build up dopamine/norepinephrine more readily and methyl donors can amplify that. Folinic acid usually delivers the same downstream support more gently.

What's the best supplement for COMT-related anxiety?

Magnesium glycinate, L-theanine and adequate B6 are reasonable starting points. Most slow-COMT users also do better with non-methylated B12 (hydroxocobalamin).
