L-Carnitine base is a nutrient that is derived from the amino acids lysine and methionine. Its name is derived from the fact that it was first isolated from meat (carnus). L-Carnitine is not considered a dietary essential because it is synthesized in the body. The body produces carnitine in the liver and kidneys and stores it in the skeletal muscles, heart, brain, and other tissues. But its production may not meet the needs under certain conditions such as increased energy demands and therefore it is considered a onditionally essential nutriention.

L-carnitine is an amino acid (a building block for proteins) that is naturally produced in the body. L-carnitine helps the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes. L-carnitine can get the amino acid fat into energy, red meat is the main source of L-carnitine, non-toxic side effects to the human body.

1. Heart Conditions (Angina, Congestive Heart Failure, Heart Attack)
a) Angina
Several clinical trials show that supplementing with L-carnitine can help reduce symptoms of angina and improve the ability of people with angina to exercise without chest pain. L-carnitine is an amino acid needed to transport fats into the mitochondria (the place in the cell where fats are turned into energy). Adequate energy production is essential for normal heart function.
Recommended Dosage —— Several studies using 1 gram of L-carnitine two to three times per day showed an improvement in heart function and a reduction in symptoms of angina.
b) Congestive Heart Failure
Many L-carnitine/CHF studies have suggested that propionyl-L-carnitine (a modified form of L-carnitine) can help improve heart function and exercise tolerance in people with mild to moderate congestive heart failure. Levels of L-carnitine are low in people with CHF. Heart muscle damage may be reduced by taking L-carnitine supplements.
Recommended Dosage —— Many doctors recommend that those with CHF take 500 mg of L-carnitine two to three times per day.
c) Heart Attack
Some studies suggest that people who take L-carnitine supplements may help reduce damage and complications following a heart attack. L-carnitine is an amino acid important for transporting fats that can be turned into energy in the heart.
Recommended Dosage —— Clinical trials have reported that taking L-carnitine (4–6 grams per day) increases the chance of surviving a heart attack.
2. Peripheral Vascular Disease
Reduced blood flow to the legs from atherosclerosis or hardening of the arteries, where plaque builds up in the arteries, often causes an aching or cramping pain in the legs while walking or exercising. This pain is called intermittent claudication, and the reduced blood flow to the legs is called peripheral vascular disease (PVD). Several studies show that supplementing with L-carnitine can help reduce symptoms and increase walking distance in people with intermitting claudication.
Recommended Dosage —— 2 grams of L-carnitine taken twice per day for three weeks
3. Obesity
In a study, people who add L-carnitine per day to an exercise program lost more weight than those who took a placebo. The amino acid L-carnitine is helpful for weight loss because of its role in fat metabolism.
Recommended Dosage —— 1,000mg of L-carnitine per day
