1.Carnitine the "energy vitamin". Every cell in your body - whether it is brain cell, immune cell, heart cell - works better when it has optimal energy available to it. Through providing optimal energy to cells, carnitine helps cells live longer, and may be an important longevity nutrient.

2. Carnitine may keep triglycerides low and raises HDL cholesterol, thus helping prevent heart disease.

3. Carnitine also may help prevent heart disease by enhancing the overall health of the heart and by helping to prevent cardiac arrhythmia, the cause of one third of all heart attack deaths.

4. Carnitine may help promote weight loss, especially when combined with a low carbohydrate diet.

5. Carnitine may increase energy levels naturally without harm to the body and without causing side effects or burnout like highly concentrated ephedra supplements. This may increase the ability of the body to exercise, and may help protect tissues from damage when they lack sufficient oxygen.

6. Carnitine may enhance sports performance and endurance and reduces the damage to tissues that can occur during exercise.

7. Carnitine and Acetyl-L-Carnitine (ALC) both may enhance immune function.

8. Acetyl-L-Carnitine may protect nerve cells from stress and deterioration, and may prevent Alzheimer's disease.

9. Acetyl-L-Carnitine may naturally increase mental energy and also help relieve depression.

10. Carnitine may enhance liver function which is critical for overall health.

In their bodies, human adults store about 20 grams of L-Carnitine, primarily in skeletal muscle, in the liver, and in the heart. L-Carnitine is not metabolized or degraded, but excreted in the urine, mostly in the form of Acetyl-L-Carnitine. Therefore, lost L-Carnitine has to be replenished by biosynthesis, by the consumption of foods of animal origin or by consumption of dietary supplements.

L-Carnitine is an essential nutrient for infants: age dependence of the last enzyme of the L-Carnitine biosynthetic pathway results in limited endogenous synthesis during the first months of life, reaching adult capacity by the age of 15 years.

Endogenous synthesis is often not sufficient to cover the animal requirements.
applications and benefits in breeding hens, broiler chickens, laying hens, turkeys and ostriches are described in this chapter. Providing the body with sufficient supplies of L-Carnitine can be expected to result in more efficient utilisation of dietary energy and protein. Additionally, the birds should be in a better position to cope with various stress factors such as SDS and ascites.

As demonstrated in university trials and in everyday practice, suplementation with Carniking improves the performance of boars, breeding sows, nursery pigs, growing and finishing pigs. The supposed benefits and recommendations are described in detail.

Dietary L-Carnitine supplements are widely used in racing animals like horses, pigeons, dogs, camels and breeding animals. Benefits and recommendations are described in detail.

In this chapter the benefits of L-Carnitine supplementation to diets for reproducing fish, larvaes, fries, fingerlings, on- and out-growing fish, smolts and others are described. L-Carnitine is also recommended in crustaceans.

Carnitine can be divided into three kinds:

Choose on the functions of products

• Acylated carnitine has a high purity. It is easy to be absorbed by human body owing to the functions of acylated transferase. It is mostly used in medicine.
  
• Owing to the products' modification, compound salts series of carnitine is not easy to absorb moisture in the air. It has more choices in the taste. Used in producing capsule, tablet, powder, biscuits, solid drink. But pay attention to the ratio of L-carnitine in the compound salts.
• Original products of carnitine:DL-Carnitine hyarochloride is the carnitine racemthe that are not separated. It is used for whetting the appetite and adjusting the functions of stomach and intestine. At present, L-carnitine can only be used in feedstuff additive for its biologicalactivity.
  
• As original products, L-carnitine and L-Carnitine hyarochloride are applicable to the above uses. Owing to its strong moisture absorption,it is applicable to making drinks, injection, capsule, tablet and others. It is widely used in feedstuff for its high content of carnitine.
