1. Carnitine is a kind of B-class vitamin. Owing to its similar
structure as amino acids, some people therefore also classify it as
an amino acid. Its main function is to supply energy through
facilitating the transport of long chain fatty acids. This prevents
the fat accumulation in the heart, liver and skeletal muscle. It
can control diabetes, fatty liver, and the fat metabolism disorder
in heart disease. Taking carnitine can reduce damage to the heart.
It can lower the level of blood triglyceride and also have certain
role in boosting weight loss. Carnitine can further enhance the
antioxidant effect of vitamin E and vitamin C.
2. Carnitine deficiency is sometimes congenital such as genetically
deficiency of carnitine synthesis with symptoms including
heartburn, muscle atrophy and obesity. Men need more carnitine than
women. Vegetarian are more prone to get carnitine deficiency.
3. If the body has sufficient iron, thiamin, vitamin B6, lysine,
methionine and vitamin C, carnitine would not be lacking.
Carnitine-rich foods contain meat and offal.
4. Synthetic carnitine is divided into three forms including
L-body, dextral and racemic with L-carnitine having the best
5. L-carnitine is a kind of compound with various kinds of
physiological activities. Its major function is to promote the
beta-oxidation of fatty acid as well as regulate the acyl ratio
inside mitochondrial to affect the energy metabolism. L-carnitine
can participate in the transport of branched chain amino acid
metabolites, and thus promoting the normal metabolism of branched
chain amino acids. In addition, L-carnitine can take effect in the
elimination and utilization of ketone bodies and play a role of
biological antioxidants for scavenging free radicals, maintain the
stability of the membrane, improve animal's immunity and the
ability of anti-stress and disease resistance.
6. L-carnitine is not a weight loss drug. Its main role is to burn
fat which is not the same thing as losing weight. To use
L-carnitine for losing weight, in addition to burning fat with its
help, a lot of movement is still the key for weight loss; instead
carnitine only play a supporting role. If exercise is not large
such as just dieting, weight loss would not be boosted by taking
1. L-carnitine is a dietary supplement newly approved by China. It
is mainly used to strengthen the soy-based baby food and promote
the absorption and utilization of fat. D- and DL-type have no
nutritional value. China states: it can be used in biscuits,
drinking fluids and milk drinks with usage amount of 600 ~ 3000mg /
kg; for solid drink, drinking liquid and capsules, the amount
should be 250 ~ 600mg/kg; the amount of milk powder is 300 ~ 400mg
/ kg; the amount of use in infant formula is 70 ~ 90mg/kg (in terms
of L- carnitine, 1g equivalent 0.68g L- carnitine tartrate).
2. Used in pharmaceutical, nutrient health food, functional
beverages, and feed additives.
3. Used as appetite enhancers.

Prospect of Function Food
L-carnitine, as a new kind of nutritional supplements, especially
as the additive of baby formula, athlete food, and food for losing
weight and bodybuilding, has been currently widely applied in
functional foods. The commercialized L-carnitine is mainly its
hydrochloric acid salt, tartaric acid salt and citric acid
1.Infant formula food
L-carnitine plays an important role in the baby’s metabolism
process of taking fat as a source of energy. Owing to that the weak
ability of baby of de no biosynthesis of L-carnitine can’t meet the
demands of its normal metabolism, it must be ingested exogenous
L-carnitine base in order to ensure the best in body fat oxidation
state and provide enough energy to maintain normal body temperature
of the baby.
In addition, L-carnitine also has certain effects on boosting
infant growth and development and improving metabolic balance. So
it is necessary to strengthen the L-carnitine in infant food,
especially in soy-based infant formula. Because of the low
carnitine content in soy, the limit of L-carnitine content in
infant formula food is 70 ~ 90mg/kg in China. Now China has
carnitine fortified infant formula milk that has entered into
2. Athletes Food
Decombaz J. et al have reported that after fierce exercise, the
free carnitine content in human muscle tissue will decrease by 20%
and the supplemental of carnitine can alleviate the fatigue of the
body because L-carnitine can promote fat oxidation of the body as
well as provide sufficient energy which is good for the sports
endurance as well as explosiveness improvement.
If L-carnitine is used in combination with octacosanol, then the
effect of improving the body strength would be multiplied,
manifested as the systemic muscles relaxation, improved explosive
power and endurance, and increased basal metabolic rate as well as
improved nutritional status of the myocardium. Commonly used method
is to add L-carnitine to athletes’ beverage.
3. Losing weight
In the early 70s, there had been patent reported of using DL-
carnitine for the prevention and treatment of obesity.
Subsequently, because of the negative effect, DL-carnitine was
replaced by L-carnitine. Practice has proved that L-carnitine
fortified food has good effect on treating the fat metabolism
disorder caused by carnitine deficiency in vivo. It can prevent
obesity and fatty liver due to the accumulation of lipids in the
liver and muscle fibers.
Kuwata thought that obesity patients due to lack of exercise have
large amount of accumulated fat and have low carnitine biosynthesis
capability. Through ingestion of L-carnitine, they can effectively
convert excess body fat into energy to be released, thus playing a
role in prevention and treatment of obesity. Thereby the
lipid-lowering food with L-carnitine as the main component becomes
very popular in the European market.
4. Important human nutritional supplements
With age, the body content of carnitine in steady decline, the
human need to add L-carnitine. Diabetes, kidney patients, mental,
physical laborers, as much waste discharge , consumption of a large
body of L-carnitine, L-carnitine can easily lead to a lack of
long-term need to supplement.
Benefit of L-Carnitine
Most important properties:
It is the transport molecule for fatty acids
It can improve the process of burning fat, and it can help you lose
It can allow better energy release (which is recommended in order
to meet cognitive performance requirements)
It improves recovery after sports
There is some evidence to suggest that L-carnitine can improve
erectile function and sperm production (however, the results of
studies on L-Arginine are more convincing).
How to Take L-carnitine
The standard dose for L-carnitine is between 500-2,000mg.
There are various forms of carnitine supplementation available.
Acetyl-L-Carnitine (ALCAR) is used for cognitive enhancement.
L-Carnitine L-Tartrate (LCLT) is typically used for physical
performance and power output. Glycine Propionyl L-Carnitine (GPLC)
is used to alleviate intermittent claudication and blood flow
300 mg - 500 mg when normally fatigued
750 mg bis 2,000 mg during fat loss
1,500 mg - 3,000 mg to improve the erection.
L-carnitine is supplemented daily.
The equivalent dosage range for other forms of L-carnitine are as
follows: 630-2,500mg (ALCAR), 1,000-4,000mg (LCLT) and
The harm of lack of L- Carnitine
L-carnitine fulfils essential functions in the body as a
vitamin-like substance, and in doing so it is involved in a variety
of processes. For example, it supports the kidneys and liver in
their role in detoxifying substances and eliminating these toxins.
It also enables the burning of long-chain fatty acids in order to
This is required by a range of muscle cells in the human body, but
particularly by those in the heart. Furthermore in all the sites
where this is possible, L-carnitine fulfils its function as a
so-called 'bio carrier' by directing fatty acids to the site of
energy production inside the membrane of the mitochondria.
The reserves of L-carnitine in the human body are relatively small-
they only consist of approximately 20 to 25 mg. Therefore
insufficient intake of food can be very quickly noticed and this
can lead to the occurrence of dangerous symptoms of deficiency.
These are frequently expressed through an increased susceptibility
to infections, disorders of lipid metabolism or reduced fertility.
An insufficient supply of L-carnitine also increases the risk of
having a heart attack, as the heart muscle is heavily dependent on
the presence of an adequate level of the nutrient.
