Gastrointestinal disturbances such as nausea, vomiting, diarrhea, and abdominal cramps have been reported after the daily use of large doses of carnitine. Body odor has also been noticed in some patients, possibly due to the formation of the metabolite trimethylamine. Upon observance of any untoward reaction, discontinue use and seek medical attention. For suspected adverse reaction, report to the FDA, www.fda.gov.ph.
