Mild side effects such as swelling, redness, and temporary lumps are common, typically resolving within 13 days
How to take L-Carnitine A usual carnitine dose is between 500mg and 2g per day, and this is sufficient to aid fat burning, promote endurance, enhance recovery and benefit from the ergogenic effects of this amino acid
The increase of L-carnitine in plasma via oral administration, even up to and exceeding 2 mg, is limited, since L-carnitine has a very poor absorption and bioavailability, a very high renal clearance, and active uptake into tissues
In HepG2 cells, L-carnitine reduced free fatty acid-induced apoptosis (72), while similar anti-apoptotic effects occurred in oleic acid-treated hepatocytes (77)
