Douglas Laboratories’
L-Carnitine supplements supply pure, natural
L-carnitine in capsule 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.
