DESCRIPTION

L-Carnitine supplements supply pure, natural L-carnitine in

tablet form.

FUNCTIONS

L-carnitine is necessary for fatty acid metabolism and energy

production in cardiac and skeletal muscle. It is involved in

fatty acid oxidation as part of the carnitine shuttle. L-carnitine

shuttles fatty acids from the cytosol (the cell fluid) into

the mitochondria (the cell’s powerhouses) for oxidation

and energy production. L-carnitine is necessary in muscle

whenever fat is utilized as an energy source. Heart muscle

always uses fat for its continuous energy demands. Skeletal

muscle begins using fat only after its glycogen reserves are

exhausted. This happens after about one hour of continuous,

strenuous exercise, e.g., long-distance running, bicycling,

swimming, or mountain climbing.

Widely distributed in foods from animal, but not plant

sources, L-carnitine is also synthesized by the liver and

kidney from two essential amino acids, lysine and methionine.

Human skeletal and cardiac muscles contain relatively

high L-carnitine concentrations which they receive from

plasma, since they are incapable of L-carnitine biosynthesis

themselves. About 95 % of the body’s L-carnitine stores are

located in skeletal and heart muscle.

L-carnitine is considered a conditionally essential nutrient.

In healthy people, plasma L-carnitine levels are adequately

maintained by the body’s own synthesis and dietary sources.

However, low L-carnitine plasma levels can be caused by

hereditary (primary) L-carnitine deficiency syndrome, or by

secondary L-carnitine deficiency. Patients with heart failure

excrete large amounts of L-carnitine in their urine.

Oral L-carnitine is readily absorbed across the intestinal

mucosa and into the bloodstream. It is then taken up from

the portal vein into the liver and subsequently released into

the systemic circulation. Most cells have a specific carnitine

transporter. Dietary L-carnitine comes mainly from animal

foods. Average non-vegetarian diets provide about 100 to

300 mg of L-carnitine per day. Vegetarian diets often provide

only trace amounts, since vegetables, fruits, and cereals are

negligible sources of L-carnitine.

INDICATIONS

L-carnitine may be a useful nutritional adjunct for individuals

who wish to support heart muscle function or skeletal muscle

performance.
