The role of L-carnitine in the weight loss fitness

L-carnitine is an amino acid that naturally appears in the animal tissue (meat products), in milk in a certain quantity, also part of breast milk.

Carnitine is located in the body in 2 forms: such as L-carnitine or in the acetyl-l-carnitine form (alkar). The synthesis of these molecules can occur endogenous of amino l-media and lysine acids. This process provides for the action of enzymes dependent on vitamin C, vitamin deficiency that blocks the biosynthesis of L-carnitine.

Mostly concentrated in fabrics such as skeletal muscles, L-carnitine has been designed for the effects on them. Here are some:

1. Beta-oxidation).

Despite its high prevalence and beta-oxidation, the L-carnitine, both from the diet and in the form of a supplement, does not seem to positively influence the metabolism of fats, unless the subject is already in another state lacking. The lacking state can be taken into consideration including veganism and vegetarism, as well as advanced age, diseases that lead to a low dietary intake (meat) or a bad use. In short, any person falling into one of the aforementioned states can benefit from carnitine supplementation to lose weight.

The standard additional interventions did not show any significant effect both on rats and obese women in terms of fat mass or body weight, following the administration of 2g/day of L-carnitine combined with aerobic exercises.

2. Vehicles and interactions with the oxidation of the beta.

On cellular level, the presence of carnitine in the form of a supplement induces enzymatic changes that increase the power of beta-oxidation when associated with physical exercise.

During exercise, L-carnitine supplements can have a lower influence on the use of the substrate, but generally do not influence the level of oxidation of glucose and fat. Even the level of exhaustion of glycogen does not seem to be influenced, instead a small increase in fat oxidation has been observed after training.

3. Metabolization of fatty acids.

As for the metabolism of fatty acids, L-carnitine acts with numerous mechanisms which, theoretically, increase the loss rate of fat, but do not seem to induce or increase the reduction of fat when using supplements. The exception is the difficulty of L-carnitine, in which the integration will restore the combustion potential of fats.

4. Carnitine implications in improving strength.

If we report specifically to force, the results are not clear. In general, studies suggest that integration with L-carnitine in all its forms does not increase acute force when ingested before training or as a daily supplement. In a study, small increases in the work capacity and explosion have been observed, while in another study it was noted that a further L-carnitine of 1.5 g for 28 days increases the power during the sprint.

5. Durestream, injuries and recovery.

The integration with L-carnitine seems to reduce the markers of muscle lesions after anaerobic exercises, possibly intensifying the oxygenation of tissues when there is no oxygen.

6. Aerobic exercises.

In subjects who face the exhaustion of glycogen following exercises, the blood concentrations of Carnitine significantly increase in people who take supplements (3g/day for 7 days), but no changes in fatigue or oxidation of fat have been detected. 15 g of L-carnitine can increase aerobic resistance, while lower doses (2G) are inefficient. Instead, the increase in resistance to lower doses (20 mg/kg) in patients with kidney disease, which cannot be applied to healthy people has been observed.

7. Anaerobic exercises.

Studies do not show concrete results on the effect of L-carnitine on anaerobic exercises. The benefits of aerobic exercises after common doses and could increase speed and volume in the sprint does not seem to be reliable.
