L-Carnitine has long been a staple in the sports and weight-loss supplement industry. Aiding in fat loss, energy production, and metabolism, 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.

5 Star Rating

L-Carnitine assists in the metabolic process of shuttling fatty acids across cell membranes into the mitochondrial matrix where energy is processed. Increasing the efficiency of this process helps the body produce natural energy more readily allowing the fat-burning process to improve. With the assistance of L-Carnitine in the energy production of free fatty acids, endurance can also be optimized and extended; as well as post-workout recovery.

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.
