Overview and Benefits of Acetyl L-Carnitine

Acetyl L-carnitine has become popular today in the world of health supplements and for good reasons. For starters, Acetyl L-Carnitine is the acetylated form of L-carnitine, a compound that is commonly found in the body. The main function of L-carnitine is to transport fats and to turn it into energy or ATP.

This essential amino acid can be taken from supplements and food sources including meat and fish. So how exactly does it generate energy from fats? What are the benefits of taking ALCAR?

Role in energy production

Acetyl L-carnitine plays a major role in producing energy for the body. What it does is transport long-chain fatty acids into the mitochondria of the cells. The mitochondria then oxidize the long-chain fatty acids and turn it into energy.

Other than the transport of fats, it also plays a major role in detoxifying the body. What it does is prevent the accumulation of toxic compounds out of the cells. Given the function of L-carnitine, it is usually found in both skeletal and cardiac muscles in order to readily provide the necessary energy to these muscle fibers when it is needed.

The body can make L-carnitine. However, there are conditions that prevent the body from manufacturing the compound. For instance, preterm infants usually can’t make sufficient amount of L-carnitine to the body.

Benefits of Acetyl L-Carnitine

There are many uses of Acetyl L-carnitine to the body. First, it is known to help individuals lose weight. Considering that it targets long-chain fatty acids, it helps the body burn hard to remove fats. It is also believed that acetyl L-carnitine can help athletes use fats in energy production rather than their glycogen stores and carbohydrates for energy prolonging their ability to perform strenuous activities.

It has also improved the overall metabolic functions when paired with alpha-lipoic acid when tested on rats.

It is also believed that acetyl L-carnitine can do wonders for the cardiovascular system. It has been used by patients who are suffering from angina. There are even instances wherein some patients have no longer used their medication.

Acetyl L-carnitine also has the ability to help the brain function better. There were animal tests that demonstrated improvement in people’s cognition after taking acetyl L-carnitine. It is also noted that this supplement has been used in order to help patients suffering from Alzheimer’s disease.

With its ability to cross the blood-brain barrier, it is believed that ALCAR is a neuroprotectant. There are also some studies saying that it has the ability to help improve overall neurotransmitter synthesis.


Should you be using ALCAR as part of your supplement? If you will ask health experts, there are many potential uses for ALCAR. This supplement can come in handy whether you are an athlete who wants to perform better in his or her sport, or you simply want to lose weight.

And the good thing about ALCAR is that there are no known side effects. Unlike stimulants such as coffee that can damage the adrenal glands, it makes use of long-chain fatty acids in order to provide the body with the necessary energy that it needs.
