L-Carnitine is an amino acid which has a role to play in the body's fat metabolism process. L-Carnitine transports fatty acids to the mitochondria, which is where they are essentially burned as fuel. This amino acid naturally occurs, although it can also be biosynthesized from two other ones. In addition to being found in a wide range of foods, it is also commonly available as a dietary supplement.

Along with being used to turn fat into energy, L-Carnitine has other potential health benefits. One of the most frequent uses of this amino acid is for treatment of heart problems, and multiple clinical studies suggest that it may be of benefit for people with particular heart issues. Several suggested medical benefits may include items such as those below:

Blood sugar control in adult-onset diabetes
Brain-related benefits
Improved cognitive abilities, memory boost
Kidney disease situations
Lowering triglycerides
Mood enhancements
Natural antioxidant
Parkinson's disease
Relief of angina symptoms

Side Effects

Ingesting normal amounts of L-Carnitine does not typically lead to serious side effects. If it leads to extra energy, the individual may have difficulty falling asleep if taking the supplement in the evening (or prior to sleeping).

Some of the mild or moderate potential side effects that have been reported are: restlessness, headache, diarrhea, nausea, vomiting, decreased appetite, and stuffed nose. A fever, rise in blood pressure, or quickened heart rate can be a serious side effect. The potential decreased appetite can also lead to an eating disorder, such as anorexia nervosa.
