Acetyl L Carnitine

Acetyl L Carnitine is an acetylated version of L-Carnitine which is claimed to be the most effective form of carnitine in terms of bioavailability.

L Carnitine has been shown to support cognitive function to improve mental performance and its most common use is to assist in weight loss as it allows the release of stored body fats into the bloodstream to be used as energy.

Curious What Amino Acid Supplements Can Do for Your Physique? Find Out with Acetyl L-Carnitine from Our Amino Acid Supplements Range!

Amino acid supplements are incredibly popular with athletes who want to keep their muscles fuelled and obtain their fitness goals. One of the amino acid supplements that has proven especially effective to obtain more lean muscle mass and lose excess fat is Acetyl L-Carnitine, one of the supplements from our amino acid supplements range. Find out more about this supplement below!

What Is Acetyl L-Carnitine?

Acetyl L-Carnitine is a form of basic L-Carnitine, but with a higher bioavailability, because the supplement has been treated with acetyl. Thanks to a higher bioavailability, Acetyl L-Carnitine will be absorbed and digested quicker, giving you almost immediate access to all the benefits this amino acid can deliver.

What Is L-Carnitine?

L-Carnitine is a supplement that has been around since the 1980s. Since its appearance on the supplement market, L-Carnitine has been incredibly popular as a fat burner. Over the course of the years, researchers found more benefits connected to L-Carnitine, which is why it is still one of the most popular amino acids today.

Even though L-Carnitine only became available as a supplement in the 80s, researchers have been looking into this amino acid since the 1950s. During their research, scientists discovered that the amino acids is created in the liver and the kidneys through a combination of two other amino acids called lysine and methionine. Then, the amino acid is stored in various muscles of the human body, our brain and even sperm cells.

Are There Different Forms of Carnitine?

There are two different forms of Carnitine on the market today, more specifically L-Carnitine and D-Carnitine. L-Carnitine is the amino acid that can be found naturally in foods, for example avocado, soybeans and meat. D-Carnitine is the second type of carnitine in existence, but due to the fact this amino acid is not biologically active, it is not used as a supplement at all.

So How Does L-Carnitine Work in the Human Body?

L-Carnitine fulfils multiple functions in the human body, but one of its primary functions is the transportation of fats, in particular the transport of long-chain fatty acids to the cells’ mitochondria. When transported fats arrive in the cell, they can be converted into energy; this energy is in turn used to produce ATP (adenosine triphosphate).

Amino acid L-Carnitine can go through the fat transport and energy conversion process when you are exercising, but also when you are resting. When the body does not have a sufficient amount of this amino acids, it will lead to your body not being able to burn the fats, because fat does not have any way to reach the mitochondria for energy conversion.

While most cases of L-Carnitine deficiency can be solved by adding a supplement to your diet, there are athletes who suffer with a serious case of L-Carnitine deficiency, which could lead to more severe health problems such as muscle weakness, stunted growth, enlarged liver and other problems related to a lack of energy conversion.

A recent study executed by researchers in Scotland also discovered another function of L-Carnitine in the human body, because they discovered that L-Carnitine can increase the function of insulin on the body cells. Because of this particular function, L-Carnitine can keep your blood sugar levels in check, even if you have been eating a little more carbohydrates than you were supposed to. For that reason, L-Carnitine is not only a great supplement to use after your training, but also after a meal.

Why Can L-Carnitine Provide Benefits for Both Weight Loss and Muscle Gains?

Experienced athletes can use L-Carnitine for weight loss, but also to gain healthy lean muscle instead of fat. The function of L-Carnitine will limit the amount of bad fats being stored in the body, so if you have the proper nutrition and the right exercise plan, the only gains you should be getting are lean muscle gains.

There have been several studies backing up the effectiveness of L-Carnitine. One study was executed at the University of Nottingham, England, where a test group of athletes followed a program of 2 grams of L-Carnitine and 80 grams of high-glycaemic carbohydrates. Compared to the control group, test subject who took L-carnitine were able to increase their endurance by 25%. Test subjects also showed a more effective fat burn compared to the control group.

Can L-Carnitine Cause Side-Effects?

Some athletes who are sensitive to L-Carnitine could experience some side-effects. Reported side-effects connected to the use of L-Carnitine include nausea, cramping, vomiting and diarrhea. We do need to mention that these side-effects were reported by athletes taking high doses of L-Carnitine, so if you stick to the recommended dose provided by Nutrients Direct, you should not be experiencing any side-effects. However, if you do experience any side-effects after the use of L-Carnitine, please stop the use of L-Carnitine immediately and contact a health professional for medical advice.

Can I Combine L-Carnitine with Other Nutrients?

Carbohydrates are commonly used in combination with L-Carnitine. Considering the fact that L-Carnitine is not able to increase the L-Carnitine in the muscles in a sufficient manner, because the insulin levels need to increase for high amounts of L-Carnitine to get into cells, an L-Carnitine and carbohydrates combination could solve that particular problem.


L-Carnitine is a suitable supplement for weight loss and for gaining lean muscle mass. However, we would not recommend using L-Carnitine when the only thing you wish to obtain is muscle gains, considering this supplement has some pretty strong weight loss properties. Instead, you can choose one of our supplement that is focussed on the increase of your muscle mass, for example Whey Protein Isolate, ND Total Whey or another protein supplement from our extensive range.

At Nutrients Direct, you can also find an extensive range of natural supplements, which only contain natural sweeteners and no artificial sweeteners or flavourings.

Since Acetyl L-Carnitine is so beneficial for weight loss, many athletes focussed on weight loss will add it to their diet and training routine. However, to get the maximum benefit from Acetyl-L-Carnitine, athletes still need to combine it with healthy foods and regular exercise. If you have been unsuccessful with weight loss in the past and are unfamiliar with the right diet to achieve weight loss success, it is therefore recommended to seek the advice of a licensed nutritionist or a personal trainer. With their help, you will have a solid meal plan and exercise routine, where you can get the most out of your Acetyl L-Carnitine.

There are other weight loss supplements that could benefits athletes who want to burn persistent fat deposits and get more out of their training routine. Since there are more weight loss supplements to take advantage of, it could be beneficial to research other possible supplements as well. So, to learn more about the weight loss supplements available at Nutrients Direct, simply head over to the “My Goal” section of the main menu and select “weight loss & toning”.
