                                According to the NIH, consuming amounts of L-carnitine as a dietary supplement that are significantly higher than typical intake can cause several gastrointestinal side effects. This makes the safety of taking high amounts of L-carnitine a critical question for those considering elevated intake, especially in the absence of a doctor's supervision.
