Here's what the research actually shows: The European Food Safety Authority (EFSA) has evaluated L-carnitine and confirmed that doses up to 3000mg per day are safe with no observed adverse effects Studies have used doses up to 6000mg daily in clinical settings without toxicity L-carnitine is water-soluble your kidneys can excrete excess amounts without it accumulating to dangerous levels Common side effects (if any) at higher doses: Mild nausea (usually disappears after 12 weeks) Loose stools initially (especially in first few days) A slightly "fishy" body odour in some individuals (this is rare and associated with a genetic condition called trimethylaminuria most people won't experience this) Who should be cautious: People with kidney disease (L-carnitine metabolism is kidney-dependent) Those on thyroid medication (some studies suggest interactions consult a doctor) Pregnant or breastfeeding women (consult a healthcare professional before use) People with existing heart conditions (though carnitine has actually been studied for cardiac benefits, professional guidance is still important) The key takeaway: 3300mg is a high dose but it is not an unsafe dose for a healthy adult
