Evidence Review

Small studies in older adults who feel tired after light activity show that taking L-carnitine supplements (2–4 grams daily) for 1 to 6 months can reduce tiredness, improve muscle strength, and help increase muscle while reducing fat.
It may also help thinking and overall energy levels.
L-carnitine helps the body use fat for energy, which may explain these benefits.
