Twinlab Acetyl L Carnitine Ingredients

As its name suggests, and unsurprisingly, the main ingredient is none other than ACETYL L CARNITINE.

Acetyl L Carnitine (or ALCAR) is a substance known since the 50s, and which became popular in the 80s for its fat burning properties.

More recent research has shown that in addition to the benefits of ALCAR for losing fat mass, this ingredient also has a positive effect on performance and recovery.

What is Acetyl L Carnitine?

Acetyl L Carnitine is a substance that is similar to amino acids and vitamins, without being one.
Close to group B vitamins, it was originally called vitamin BT.
ALCAR forms naturally in the body, in the liver and kidneys, from 2 amino acids: lysine and methionine. It is then stored in the muscles, primarily the heart, but also in the brain, and even in sperm in humans.

Acetyl L Carnitine is found in good quantities in meat and other animal products, as well as in lesser quantities, in avocados or soy.

There are several forms of carnitine:

  • D Carnitine, which is inactive and not sold as a supplement;
  • L Carnitine, which is the form of carnitine usually found in nature, and which is therefore biologically active;
  • Acetyl L Carnitine, which is also found in the Central Nervous System, and which plays a role in the production of energy, or the production of an essential neurotransmitter, acetylcholine.

What is the role of Acetyl L Carnitine in the body?

Acetyl L Carnitine participates in the transport of fats, and more specifically long-chain fatty acids, into the mitochondria of cells.
The fatty acids are then oxidized and used by the body as fuel, in the form of ATP.
This action is done both at rest and during the practice of a sport, and would also be more effective during intense sports practice.

Acetyl L Carnitine also acts on insulin, increasing its influence on muscle cells. This will have the effect of better regulating the level of glucose in the blood.

Finally, Acetyl L Carnitine helps increase sports performance and reduce fatigue.
It is the increase in calorie burning, coupled with a decrease in the amount of glycogen used and an increase in blood supply to the muscles that allows the body to receive more nutrients and hormones to respond to his needs during the exercise.

ALCAR is also related to nitric oxide.
First, it reduces the oxidative damage of nitric oxide to the body.
Second, it increases the activity of a key enzyme involved in the production of nitric oxide. As a result, the ON level rises, causing a noticeable improvement in energy levels during exercise, but also in post-exercise recovery.

What does science say about Acetyl L Carnitine?

Acetyl L Carnitine has been widely studied and its properties are clearly recognized.

To concretely determine the benefits of this substance, we have chosen to mention a recent study that was carried out at the University of Notthingham Medical School.

This study focused on 2 groups of athletes:

Group 1 received in the morning on an empty stomach 2g of ALCAR + 80g of a food preparation based on carbohydrates (slow sugars) with a high glycemic index, then again 4 hours later.
Group 2 received only the carbohydrate preparation.

The results of this study are as follows:

  • During low-intensity exercise, athletes in group 1 burned 55% less muscle glycogen and 55% more body fat than group 2;
  • Group 1 had 25% longer exercise capacity than group 2;
  • Despite the 640 more calories provided by the carbohydrate preparation, the subjects in group 1 did not gain weight, while the individuals in group 2 gained more than 2.5 kg of fat mass.

These results clearly show the interest of Acetyl L Carnitine in burning fat and reducing fatigue.

Side effects of ALCAR

At normal doses, Acetyl L Carnitine has very few side effects.
In high doses, however, it can cause the following side effects: nausea, abdominal cramps, vomiting, diarrhea.
More rarely, it can cause muscle weakness in uraemic people, or convulsions in people with seizure disorders.

Finally, ALCAR also has, for men only, a rather pleasing side effect: that of increasing erectile function and fertility.

Its effectiveness still seems largely optimized by following a specific diet.

ALCAR would refine the silhouette, help to lose weight, and effectively boost energy levels.
