Nevertheless, LC is still used by elite [ 9 ] and sub-elite [ 10 ] athletes.

Recent studies suggest that LC supplementation may elevate muscle TC content; therefore, modify muscle fuel metabolism and performance during the exercise. Due to insulin-mediated LC transport to the muscle, oral administration regimen should be combined with CHO. Because of LC poor bioavailability, it is likely that the supplementation protocol would take at least 3 months.

Shorter period of supplementation may be effective in prevention of exercise-induced muscle damage, but not metabolic changes. On the other hand, it is also clear that prolonged LC supplementation elevates fasting plasma TMAO [ 16 , 17 , 18 , 58 , 59 ], compound supposed to be pro-atherogenic [ 61 ].

Therefore, additional studies focusing on long-term supplementation and its longitudinal effect on the TMAO metabolism and cardiovascular system are needed.

Some medical professionals prescribe L-carnitine in supplement form to help support those with heart conditions, diabetes, erectile dysfunction, and other health conditions.

Take a look below at 5 benefits of L-carnitine weight loss supplement and how it can help you shed pounds both directly and indirectly. With higher levels of L-carnitine, your body becomes more efficient at burning fat. Not only does this decrease the amount of fat that your body stores, but it also helps reduce visceral belly fat, the kind that surrounds your vital organs and potentially leads to fatty liver disease and other serious health conditions.

L-carnitine not only helps you increase the amount of fat burned with every workout, but you also get more energy for better workouts and an active lifestyle. Taking that energy increase into your exercise routine will allow you to perform with more intensity, providing a boost to your metabolism. L-carnitine helps reduce the buildup of lactic acid in your muscles.
