What are the side effects of L-Carnitine?Updated a year ago

If consumed correctly, you shouldn’t experience any side effects. However, side effects like heartburn, diarrhea, seizures, and stomach discomfort are all possible, particularly in long-term use. You may also experience a ‘fishy’ odour in the breath, sweat and urine. Discontinue use and consult a GP if you experience any of these symptoms  (WebMD).
