Combining the two might potentially intensify these symptoms, though this has not been formally studied Trimethylamine N-oxide (TMAO) concerns : Some observational research suggests that L-carnitine supplementation may increase TMAO levels, a metabolite associated with cardiovascular risk in some studies, though this relationship remains controversial and causality is unproven Unnecessary supplementation : For most people consuming a balanced diet, L-carnitine deficiency is rare, and supplementation may be unnecessary Cost implications : Purchasing supplements alongside prescription medication represents an additional financial burden without proven incremental benefit Other side effects : Tirzepatide can cause injection-site reactions, while L-carnitine may cause a characteristic 'fishy' body odour at higher doses Importantly, if you experience severe, persistent abdominal pain (with or without vomiting) while taking Mounjaro, seek urgent medical assessment as this could indicate pancreatitis or gallbladder disease
