Carnitine Fat
L-carnitine is a nutritional supplement that has been considered by bodybuilders and other athletes as a safe and useful for creating more and more efficient muscles. Some Doctors and researchers have focused on the L-carnitine to prevent muscle wasting in people who need kidney dialysis, alternative medicine providers suggests that L-carnitine may stop cellular aging. In making healthy use of L-carnitine, we gather certain information to any potential buyer should have.
What is L-carnitine, anyway?
L-Carnitine is a modified amino acid produced by the liver. Most amino acids are the building blocks of proteins, which in turn provide the bulk of the structure and function of the body. L-carnitine is different to amino acids, and is not part of a protein, but rather serves as a delivery van, the movement of fats in special parts of our cells, where can be used for energy.
Several conditions can cause the lower level of L-carnitine, including:
Rare genetic- (Inherited) conditions
"The loss of L-carnitine during dialysis (the mechanical process used to clean the blood of patients whose kidneys can not handle)
Some-people (for example, babies, premature) I can not get enough of L-carnitine in their diet and can not make sufficient quantities in the liver
Where I can get?
Most people synthesis (making) a sufficient number of L-carnitine needs in the liver. You can also get significant amounts from your diet:
"Ground beef
Pork
Milk
-Fish
Even vegans are generally more well it was not necessary to eat meat to have the necessary L-carnitine can also get small amounts from such sources such as avocados, whole wheat bread and asparagus.
Should I take supplements of L-carnitine?
People who have disease liver does not allow the L-carnitine is synthesized to take supplements of L-carnitine to survive, it is also true of people born with kidneys that excrete L-carnitine in large quantities.
Because L-carnitine is so important in the creation of energy, many people rely on it to improve their sporting activity. They believe that this is particularly important in the muscle, which often require a large amount of energy to increase the size (as in the construction of the body) and function for long periods of time (marathon runners).
Unfortunately, studies to date have not demonstrated conclusively that supplementation improves athletic performance or muscle mass. Some research suggests, however, that larger studies be done to see if there is an effect on certain types exercise or certain subgroups of athletes.
There is little evidence of L-carnitine may be useful for people with conditions that lead loss L-carnitine, for example:
* Aging. Some studies suggest that the loss of power and memory may be due in part to declining levels of L-carnitine in older rats and mice, L-carnitine has been shown to partially reverse these changes. important studies are planned to see whether L-carnitine has the effect on human aging
* Cardiac lesions. Several human studies suggest that supplementation with L-carnitine after myocardial infarction (heart attack) can help the heart to repair damaged cells and help it run better. L-carnitine seems to be able to help people with angina pectoris – the pain that sometimes precedes a heart attack.
* The loss of kidney disease muscle. Management Food and Drug Administration (FDA) approved the use of L-carnitine in dialysis patients to prevent and treat carnitine deficiency is caused by kidney disease and dialysis. Although this does not work for all patients with muscle weakness and loss, which is available as an alternative if conventional treatments do not work.
The short answer …
Unless you're one of the conditions in some, it is unclear whether L-carnitine will help you achieve your goals. Being given that for some people (including those with seizure disorders who have Alzheimer's disease, or who are pregnant and lactating) and supplements L-carnitine can be dangerous, it would be best to wait until more information is available.
