What to watch with COMT and Stress?

The COMT gene encodes an enzyme that breaks down stress-related neurotransmitters like dopamine and norepinephrine. Common variants (e.g., Val158Met) slightly alter enzyme activity: Val/Val carriers metabolize faster, Met/Met slower. This can modestly influence stress resilience, but effect sizes are small and ancestry-specific. Lifestyle factors—sleep, exercise, mindfulness, diet—have a far greater impact on stress regulation than this single SNP. DNA tests alone cannot provide actionable stress management advice. Be cautious of overinterpretation: a 'slow' COMT variant does not guarantee higher stress sensitivity. The evidence is mechanistic, not clinically validated. Avoid marketing claims that promise personalized stress solutions based solely on COMT. Focus on evidence-based stress reduction techniques instead.
