As previously mentioned, early studies using direct measurements in muscle after 14 days on 4 to 6 g of carnitine per day failed to show increases in the muscle carnitine concentration (4, 5)
[4] This is supported by a study of resistance-trained athletes showing that 2g per day of l-carnitine l-tartrate may have helped increase oxygen delivery into the muscle cells themselves

The largest longitudinal study looked at 37 randomized controlled trials with 2,292 participants
