Carnitine is an amino acid-like compound that helps the body produce
energy. While readily abundant in meats and dairy foods, some people take
carnitine in supplement form to increase vitality and energy. Carnitine
transports fatty acids to the "factory" portion of cells, which then
convert the fat into energy that the heart, muscles, and other body
tissues can use.
Without enough carnitine to move fatty acids to the right place, your body
will eventually wear down, and you may feel drained and tired. The heart
in particular is highly dependent on carnitine, and taking it in
supplement form is currently being explored as an option for speeding
recovery after a heart attack as well as for treating angina (chest pain),
arrhythmia (irregular heartbeats), and congestive heart failure.
Carnitine plays a critical role in metabolizing a number of other
important substances as well, which helps to explain why it holds promise
for so many disorders.
-
Some studies indicate that carnitine may improve endurance in those
weakened by disease, and boost an immune response in people who are
HIV-infected.
-
A form of carnitine that is produced naturally in the
brain--acetyl-L-carnitine, or ALC--is currently being studied in
supplement form as a possible treatment for memory loss associated with
aging and Alzheimer's disease.
-
Studies are conflicting regarding the effectiveness of carnitine for
enhancing athletic performance by improving energy and fat metabolism. A
positive effect appears most pronounced for endurance-related events, such
as cycling and long distance running.
-
Carnitine supplements are particularly valuable for people with
conditions that can interfere with its absorption, including
various liver and kidney problems, metabolic stress, long-term
alcohol use, and in some cases, a high-fat diet.
Conclusion:
Improves
energy production. Carnitine plays an important role in lipid metabolism
and energy production. It is essential for normal mitochondrial
function, acting as a transporter of long-chain fatty acids into the
mitochondria for beta-oxidation and energy production.
Supports normal memory and concentration. Carnitine may enhance memory
and concentration by increasing energy production in the brain, and by
increasing levels of acetylcholine. Acetylcholine is an essential
neurotransmitter which is reduced in people with age-related memory
loss. Cerebral Carnitine levels are reduced in chronically fatigued
individuals. |
