LIQUID L-CARNITINE LS3 is a true advancement in L-Carnitine supplementation. It is a combination of L-Carnitine, Acetyl-L-Carnitine and L-Carnitine L-Tartrate. With this, iSatori has created a calorie free, sugar free, gluten free, great tasting liquid that supports fat loss and metabolism.∆ L-CARNINE LS3 + ENERGY is also available as with the same base formula and added energy components.

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.

Gives me energy

Good supplement for energy boost.

Great for an extra boost if you’re training on a consistent basis. I’ve used it on and off for a year with weight/cardio training and remained lean/cut. It is not a miracle fat burner so ignore the reviews that mention that it didn’t work. Think of it as a supplement to your workouts.

Muy bueno

This is the highest content of L-carnitine per dose that I have seen.

I have used it for quite a few months now. I increased the dose from twice daily to three times daily. I have lost substantial amount of fat, but of course I am doing exercise and proper diet as well. Overall, I am happy with the results.
