Catechol-O-Methyltransferase (COMT) is a metabolic enzyme that breaks down catecholamine neurotransmitters including dopamine, epinephrine, and norepinephrine. This enzyme plays a crucial role in maintaining neurotransmitter balance, affecting mood regulation, stress response, and cognitive function.
Reported Benefits (Provisional)
Origin & History
Catechol-O-Methyltransferase (COMT) is an enzyme found in the brain and liver, playing a crucial role in the breakdown of catecholamines such as dopamine, epinephrine, and norepinephrine. It is produced naturally in the body and can be studied through recombinant DNA technology.
Research Narrative (Provisional)
Research includes genetic studies and observational studies linking COMT activity to mental health and cardiovascular conditions. There is ongoing research into its role in pharmacogenomics.
Preparation & Dosage

Nutritional Profile
- Enzyme activity is influenced by genetic polymorphisms. - Requires magnesium as a cofactor for optimal function. - Involved in the methylation pathway, affecting neurotransmitter levels.
Reported Mechanism (Provisional)
COMT catalyzes the methylation of catecholamine neurotransmitters using S-adenosyl methionine as a methyl donor, converting dopamine to 3-methoxydopamine and norepinephrine to normetanephrine. The enzyme requires magnesium as a cofactor and primarily operates in the prefrontal cortex where dopamine reuptake transporters are sparse. COMT activity directly influences dopamine clearance rates, with genetic polymorphisms affecting enzyme efficiency and subsequent neurotransmitter levels.
Clinical Narrative (Provisional)
Research on COMT focuses primarily on genetic variants rather than supplementation, as COMT is an endogenous enzyme. Studies of the Val158Met polymorphism in over 10,000 subjects show that individuals with different COMT variants exhibit varying cognitive performance and stress sensitivity. Meta-analyses indicate that Met/Met genotype carriers have 3-4 fold lower enzyme activity, leading to higher dopamine levels and better working memory but increased stress vulnerability. Clinical evidence for COMT as a therapeutic supplement remains limited, with most research examining genetic expression rather than exogenous enzyme administration.
