Dimethylamine in human urine.
The urinary excretion of dimethylamine has been measured in 203 unrelated healthy volunteers (102 male) who maintained their normal diets. The results for female volunteers are the first reported in the literature. The average daily output was 17.43 +/- 11.80 mg (mean +/- S.D.) (21.21 +/- 14.78 male; 13.74 +/- 5.65 female) with values for the majority of the population lying within the 0.68-35.72 mg range. Four male outliers excreted up to 109.2 mg; these large amounts of dimethylamine were presumed to be of dietary origin. The literature pertaining to urinary levels of dimethylamine has been summarised and integrated with the present observations.
