What does L-CARNITINE LS3 do?


L-Carnitine has been a staple in sports and weight-loss supplements for years. Aiding in fat loss, energy production, metabolism, and insulin modulation, L-Carnitine is a great supplement for not only those who are looking to supercharge their metabolism, and change body composition but anyone looking to optimize their performance in and out of the gym. ∆


L-Carnitine assists in the metabolic process of shuttling fatty acids across cell membranes into the mitochondrial matrix where energy is processed. Being more efficient in this process helps the body produce natural energy more readily.


With the assistance of L-Carnitine in the energy production of free fatty acids, endurance can be optimized and extended; as well as post workout recovery. When performing lower intensity type workouts like jogging on a treadmill or climbing on a step machine, your body tends to use Free Fatty Acids (FFAs) as a primary energy source. While L-Carnitine helps increase the efficiency of using FFAs as an energy source, the end result is more useable energy to support physical endurance.
