L-Carnitine is a non-essential amino acid and is a natural substance found both in the body and in food. The main function of L-Carnitine is to help the body produce energy, aid in muscle movement, as well as the normal functioning of the brain and heart.

L-carnitine is responsible for escorting long-chain fatty acids to your cells’ mitochondria, where energy is produced. L-carnitine also removes the toxic by-products of energy production out of your cells, preventing toxic build-up. 

There are two types of Carnitine; L-carnitine Tartrate and Acetyl L-carnitine.

The main difference between the two types is that Acetyl Carnitine has an acetyl group attached to the carnitine molecule which changes its functionality, allowing it to pass through the blood-brain barrier.



L-Carnitine is a popular supplement for people who play sport and workout, as it has some incredible benefits for cognitive function, weight loss and performance. Athletes and those who train often tend to need more carnitine than they are capable of producing endogenously. L-carnitine can be particularly important during periods of intense exercise as it helps to preserve muscle glycogen levels, aid in recovery and the reduction of muscular soreness. This special amino acid also increases blood flow to the muscles, meaning more nutrients and hormones go where they're needed, leading to better pumps and muscular growth.

L-Carnitine is often used in pre-workouts and Fat burners as it helps your body to produce energy by utilizing the body’s fat stores allowing you to work out for longer and ultimately aiding in fat loss. Taking L-carnitine on a daily basis has been proven to increase the blood and muscular concentrations of this amino acid-like compound, enhancing Fat Metabolism.

Acetyl L-carnitine has also been shown to aid in cognitive function, leading to improved memory, Alertness, Concertation and learning capacity.


ONEST uses both acetyl and Tartrate forms of Tarnitine in HyperBurn to naturally enhance Fat burning and weight loss as well as increasing endurance and muscle recovery.
