Drug Metab Dispos. In individuals with a hereditary defect in flavin-containing monooxygenase 3 (FMO3), bacterial TMA production is believed to contribute to the symptoms of trimethylaminuria (TMAU; fish-odor syndrome). It might also be a disability if your addiction was originally caused by medical treatment or medically prescribed drugs. By alleviating the inflammation and clearing away this problem tissue it relieves the symptoms and allows the healing system to rapidly repair the problem.

A novel mutation in the flavin-containing monooxygenase 3 gene (FMO3) of a Norwegian family causes trimethylaminuria. [2][3] When FMO3 is not working correctly or if not enough enzyme is produced, the body loses the ability to properly convert trimethylamine (TMA) from precursor compounds in food digestion into trimethylamine oxide (TMAO), through a process called N-oxidation. Trimethylamine (TMA) is a chemical created in the intestines by a few bacteria during the digestive process of foods containing choline. Copyright 2018 FitCube Nutrition. (2017).
