Trigonelline is an alkaloid with chemical formula C7H7NO2. It is an inner salt formed by the addition of a methyl group to the nitrogen atom of niacin. Trigonelline is a product of the metabolism of niacin (vitamin B3) which is excreted in the urine.[1]
Trigonelline is also found in coffee, where it may help to prevent dental caries by preventing the bacteria Streptococcus mutans from adhering to teeth.[2]
