Realities of L-carnitine

According to various studies worldwide, such as those of Olli Heinonen world expert in carnitine research, from Turku University Hospital in Finland , the consumption in a natural way or in supplements, of this nutrient, actually implies:

1. A balanced diet contains more quantities of L-carnitine than is needed daily, since it is easily obtained from animal products mainly lamb, cow and sheep meats.

2. The use of high doses of L-carnitine will produce a greater use of fats as a source of energy against sugars, causing loss of fat mass, reducing muscle fatigue and recovery time after exercise, so it became fashionable among athletes.

3. According to a study of Children's Hospital, University of Rostock, Germany , the consumption of L-carnitine favors only people with obesity : the oxidation of fats may be due to other factors, such as increased post-exercise metabolism, diet, more exercise, among others, therefore, the applicability fails in normal-weight, healthy or athletic individuals.

4. According to tests performed by David Costill, exercise physiologist , there were no decreases in blood lactate, or increases in the concentration of L-carnitine in the muscle after supplementation, only increases in plasma concentrations, without increases in physical performance.

5. The intake of carnitine does not cause changes in lactate levels, peak VO2 or performance and only slight increases in intramuscular and plasma levels have been found, but they do not cause effects on the increase in oxidation of the fatty acids.

6. L-carnitine is not a reality fat Burner , but a means of transport that transforms the fat into energy. Without L-carnitine, fatty deposits can not be oxidized and, as a consequence, are stored in the bloodstream and in the body's cells.

7. Although L-carnitine does not seem to cause significant side effects, high doses of 5 or more grams per day can cause diarrhea, mainly.

So far, there are not enough studies that can prove that higher or more frequent doses are actually functional or beneficial for burn fat Y lose weight , as well as promoting greater physical performance against exercise.
