Best Acetyl L-Carnitine Supplement

 

If you are looking for natural ways to lose some excess fat, you have come to the right place!

What if I would tell you that there is a solution that can help you use your fat stores as a primary source of energy when you are working out?

How does this sound to you?

What if I would tell you that this same solution can, at the same time, help you increase your bodybuilding performance and have a better brain activity? 

If you are interested, then continue reading as in today’s post, I want to talk about the Acetyl L-Carnitine supplement and how to choose the best Acetyl L-Carnitine supplement to help you meet your fitness goals faster.

What is Acetyl L-Carnitine?

L-carnitine is a natural substance (amino acid) that the human body partially produces on its own when we consume a sufficient amount of protein food (meat, poultry, eggs, etc.).

The main function of this amino acid is to transport fatty acids into the mitochondria of the muscles, where fat burning occurs under certain conditions (keeping certain heart rate indicators).

Acetyl Carnitine is a type of L-carnitine that was developed for faster absorption by the body. Additionally, it has a positive effect on brain function, improves memory and it also slows down aging processes.

Fundamentally, Acetyl L-Carnitine is not exactly a fat burner. It is most likely a biologically active supplement that helps speed up metabolism, increase stamina and positively affect the work of the cardiovascular system.Best Acetyl L-Carnitine Supplement

Accordingly, it helps to increase the intensity of the training, while triggering the generation of energy from fat adipose tissue. Therefore, burning excess fat becomes a somewhat side effect, but let’s agree, a positive one, right?

This form reduces fatigue during intense workouts, increases endurance, protects against stress, improves memory and, of course, helps to effectively burn subcutaneous fat.

I want to make an important clarification here. There will be no sense from taking Carnitine without the necessary components: physical activity (especially cardio) and a balanced diet.

Hence the different opinions about this supplement. Discontent is usually expressed by those who hoped for a “magic pill” that helps to lose weight while sitting on the couch.

But those people for whom the notorious healthy lifestyle is not an empty phrase, consider L-carnitine an excellent tool for achieving good physical shape.

A Little History About L-Carnitine

For the first time, L-Carnitine was discovered in 1905 by Russian scientists that were studying animal muscle tissue. 

The new substance got its name from the Latin word “carnis”, which in translation means “meat”.

Chemists learned to create L-Carnitine artificially much later – in the 60s of the last century. The drug received positive reviews and gradually began to be used in medicine.

For the first time in big sports, L-carnitine was used during the 1980 Olympics. The supplement was included in the diet of the Italian national football team.

Subsequently, L-carnitine have been started to be widely used in the sports nutrition and medicine industries.


Main Functions of Acetyl L-Carnitine Supplement

Increased Resistance to Physical Stress and Loads

Acetyl L-Carnitine is recommended for those who can hardly tolerate enhanced training, has poor adaptive capabilities and is actively involved in sports. L-Carnitine increases the athlete’s potential and greatly facilitates adaptation to power loads.

Increased Mental and Physical Activity

Acetyl L-Carnitine gives the ability to expand the mode of sports training and enter a new professional level.

Fat Burning Effect

Against the background of anaerobic loads, Acetyl L-Carnitine increases the amount of consumed fatty acids for the formation of energy that is so much useful for the athlete.

Therefore, Acetyl L-Carnitine is recommended to take in order to get rid of excess fat and bring the weight back to normal. 

It is worth noting separately the prolonged effect of long-term use of Acetyl L-carnitine for weight loss. The drug promotes the rapid oxidation of not only existing fats but also coming from food.

As a result, they do not accumulate in the body but are immediately transmit the energy to the body. This improves both physical and mental performance.

After completion of the course, this effect persists for several months. In case of proper nutrition, L-carnitine taken previously for weight loss will be valid until the start of the next course.

L-Carnitine is taken for 1 month. Then, there is a need for a break for 1.5-2 months.

Anabolic Effect

It was experimentally proved that L-carnitine helps to increase the rate of muscle mass gain and contributes to muscle relief.

Lowering Cholesterol, Additional Protection of the Heart and Blood Vessels

L-Carnitine reduces the amount of low molecular weight cholesterol that affects the blood vessels and can cause the development of stroke, heart attack and other dangerous cardiovascular diseases.


How to Chose the Best Acetyl L-Carnitine Supplement?

In order to see positive results after using the supplement, there is a need to choose it correctly.

There are a lot of L-Carnitine supplements, so how do you actually know which one is the best to pick?

What, first of all, should you pay attention to when buying? Here are several criteria that will help choose the best L-Carnitine supplement.

Composition

It is always best to study the product’s composition before buying. The best Acetyl L-Carnitine supplement should not contain sugars and carbohydrates.

Preservatives are also unacceptable in a quality product. Sucralose or stevia can serve as a sweetener and even these in a minimal amount.

Release Forms of Acetyl L-Carnitine Supplements

Liquid

In this form, Carnitine is absorbed faster by the body, and, therefore, begins to act sooner.

The disadvantage is the presence of preservative additives and sweeteners to increase shelf life and improve palatability (the taste).

Powder

The disadvantage is that the powder needs to be diluted with something, however, this is also a convenient part because it can be added to the finished drink.

Capsules/Tablets

This option is absorbed longer than the liquid form, but it contains a minimum of foreign substances.

When buying, you should pay attention to the composition and concentration of pure L-Carnitine.

The Manufacturer/Brand

Many brands have already proven the effectiveness of their products. It is better to opt for well-known brands, the additives of which are used by many athletes around the world for many years.

Price

The price depends on the release form of the supplement. Pills are affordable, but their speed of exposure is small. Liquids are the fastest absorbing form, but they have the highest price.

The Recommended Dosage of Acetyl L-Carnitine Supplement

How to take L-Carnitine supplement in order to see the maximum effect?

These may vary depending on the purpose of taking Acetyl L-Carnitine. Most of the resources suggest taking between 1-3 g of Acetyl L-Carnitine per day.

If you exercise intensively at least 3 times a week, you need 1200 mg of L-carnitine for weight loss per day. This dose should be divided into 2 parts. The first should be taken shortly before meals in the form of capsules, and the second in liquid form 30 minutes before training.

When to Take Acetyl L-Carnitine Supplement?

General recommendations on how to take L-carnitine are as follows:

200 mg 15-20 minutes before breakfast;

200 mg before lunch;

200 mg before dinner;

600 mg in liquid form before training.

Acetyl L-Carnitine must be taken in courses, but with mandatory interruptions. Prolonged use may lead to a decrease in the natural synthesis of L-carnitine in the body.

L-Carnitine is produced in the liver and kidneys of humans, but usually in small quantities. Synthesis takes place with the participation of other important substances: B vitamins, vitamin C, iron, lysine, and some enzymes.

If these are not enough due to increased loads or some deviations in nutrition and health condition, L-carnitine ceases to be excreted in the right amount, causing weakness, and as a result, decreased performance.

Therefore, L-carnitine plays a crucial role in metabolic processes and its deficiency provokes:

  • decreased immunity;
  • fatigue;
  • cardiovascular diseases;
  • metabolic disturbance and, as a consequence, the appearance of excess weight.

If you notice these symptoms on the background of a diet or intense physical activity, consider taking L-carnitine additionally. The main advantage of the drug is its absolute safety when used correctly.

Side Effects and Precautions

For healthy people, the intake of Acetyl L-Carnitine supplement should not cause serious problems.

However, there are some cases when this amino acid is not recommended, and these are:

  • Peripheral Vascular Disease
  • Hypertension
  • Cirrhosis
  • Diabetes
  • Kidneys Diseases

It is also not recommended for pregnant women, as well as during breastfeeding. I always recommend consulting your physician before deciding to start taking any type of dietary supplement.

Other contraindications are:

  • individual intolerance;
  • allergic reactions;
  • irritability and insomnia.


As you can see, there are not so many contraindications. L-Carnitine is one of the most harmless sports supplements.

However, it is worth noting that no matter how much we would not like this, “super-pills” simply do not exist.

The main side effect that is possible with L-carnitine is a sharp increase in appetite. It is caused by the main property of the drug, which is to accelerate metabolism.

Many manufacturers recommend taking L-Carnitine for weight loss in conjunction with microcrystalline fiber (MCC). It helps control appetite, and with it, the diet goes much easier.

Some people also claim that L-Carnitine for weight loss causes increased anxiety and irritability. Most likely, this effect is explained by the stimulating effect of the drug.

If you notice this symptom, reduce the use of other drugs that stimulate the nervous system (like caffeine and guarana).

Although nutritionists note that with proper diet and a reasonable amount of exercise, taking L-Carnitine for weight loss will not cause any changes in appetite.

To do this, adjust the usual low-calorie diet, increasing the number of meals up to 6 times a day.

Fractional nutrition, rich in protein, fresh fruits and vegetables, and complete elimination of alcohol and sugar, will benefit the body and accelerate weight loss.

  1. This was an extremely comprehensive review of the different brands Acetyl L-Carnitine available.

    I knew it could be used for sharpening mental acuity, but didn’t know it aided in fat mobilization into the mitochondria of the muscle cells.

    Including your preferred options was helpful as you have a thorough understanding of how this supplement works in the body, as well as shopping for a good bargain.

    One quick question for you. What would be your specific cardio recommendations while using Acetyl L-Carnitine?

    • Hi, Rodney,

      Thank you for reading, as well as for your question!

      Overall, in terms of weight loss, L-Carnitine is most effective in the training program, which includes 3 strength workouts per week, and 4-6 cardio workouts of varying intensity and duration.

      I have written an article about the training program, as well as diet tips&tricks for Endomorphs and you can check it out here.

      Hope this helps!
