XBrain® Acetyl L-Carnitine
XBrain® Acetyl-L-Carnitine is a superior carnitine supplement in a form that provides you with carnitine in a form with very high bioavailability. Carnitine is necessary for burning fat and carnitine supplements have been shown in scientific studies to enhance fatty acid metabolism. I am sure the benefits of this are obvious to you. You enhance energy availability to improve your workout endurance, and the energy comes from burning fat improving your fat to lean muscle ratio. This supplement is a great addition for active sports people who care about reducing their fat reserves and preventing muscle catabolism.
Boost Cellular Energy
The way L-carnitine works is very well documented. Fatty acids are a much richer energy source than carbohydrates, which is why the body uses them to store energy. To release energy from fats they have to undergo a process called beta-oxidation in mitochondria. Unfortunately this process is not as fast as you sometimes need it to be. The problem is that normal length fatty acids can’t passively cross the mitochondria membranes, they need to be actively transported across them, and it is carnitine that does the transporting. This is the rate-limiting step in fatty acid metabolism. When levels of carnitine are elevated, beta-oxidation rates improve, you burn more fat.
Carnitine is a completely natural substance; in fact your body synthesizes it from the amino acids lysine and methionine. Although your body can make it, and it is therefore not technically an essential nutrient, studies show that taking a carnitine supplement speeds up the rate of lipid metabolism. This shows that the body cannot synthesise optimal amounts of carnitine to power up fatty acid beta-oxidation when your energy needs are very high. Taking a supplement has scientifically proven benefits for active athletes.
Acetyl L-Carnitine for Faster Recovery
A carnitine supplement is not just excellent for athletes because it creates energy, it also saves muscle proteins from breakdown. When you are expanding more energy than you can get from carbohydrate metabolism, for example during strenuous exercise, your cells start looking for other sources. Under these conditions fat oxidation increases to make up for the energy shortfall. However, fatty acid transport across mitochondrial membranes doesn’t happen fast enough to provide all the ATP muscle cells need. To get more energy the body starts looking for other sources, such as amino acids. It begins to break down the proteins in your muscle, releasing free amino acids. These get converted to glucose in the liver.
Obviously muscle protein breakdown is the exact opposite of what you are hoping to achieve as an athlete. Taking a carnitine supplement will speed up fatty acid oxidation so more energy is obtained from fats and there is less of a chance of losing protein.
You might be wondering why you should buy acetylated L-carnitine (also known as ALCAR) rather than just carnitine. As always one of the difficulties of preparing effective supplements is ensuring bioavailability. It doesn’t do you much good to take a supplement if you can’t officially absorb the nutrients before it passes through your digestive system. Studies show that ALCAR is more easily absorbed than carnitine. In your body the two forms exist in equilibrium with each other, carnitine is converted to ALCAR through acetylation, and ALCAR is converted to carnitine. Whichever form you take has the same effect of improving your fatty acid metabolism, but the ALCAR form has a higher bioavailability and is therefore superior.
Acetil L-Carnitina is therefore a carnitine supplement with improved bioavailability. It will increase the levels of L-carnitine in your skeletal muscle cells. Since carnitine is the transporter necessary to allow fatty acids to cross the mitochondrial membrane, and since this is the rate limiting step in fat metabolism, Acetil L-Carnitina will increase the rate at which you burn fat. This improves the way you can utilize this very rich source of energy, improving your endurance and performance during a workout, when more energy is always needed. It will also allow you to burn more fat, and protect your muscle proteins from being broken down, improving your lean muscle to fat ratio. Acetil L-Carnitine is a superior ALCAR supplement highly recommended to athletes and bodybuilders who want to maximize the benefits of their training routines.
