L-carnitine for weight loss - how to take, which is better, side effects

Thanks to science and modern technology, many ways have been found to help get rid of excess body fat in the body.

Classic and recognized by all - it is physical activity and proper nutrition. But if you combine them with some bio-additives, the results will be faster. We are talking about the use of L-carnitine for weight loss.


L-carnitine - what is it?

L-carnitine is a replaceable amino acid or vitamin B11, produced by the human body. But for this you need to fully eat, with the presence in the diet of animal proteins. The substance transports fatty acids through the circulatory system, participating in the burning of fat.

L-carnitine also helps cells to “correctly" produce energy, removing the substances that the body has spent. When there is enough vitamin in the body, lipids are faster processed and converted into energy. Thanks to L-carnitine, carbohydrates and proteins break down more slowly - this gives a person strength and vigor, increases overall endurance and activity.

And in areas where fat is most deposited, the process of fat formation slows down. But in order for the properties of a substance to be fully manifested, certain conditions must be met.

In sports nutrition supplement is used to gain the best physical shape and weight loss. But remember - without regular training, and preferably, enhanced aerobic, the opposite effect is possible.

Only with intensive running, walking, aerobics, or another similar form of physical activity with increased body temperature and oxygenation of tissues, is it possible to capture a large number of fat cells with L-carnitine.

  • Liquid L-carnitine for weight loss is convenient because for its reception does not require special training - just open the container and drink. There are still syrups with a high concentration of the substance, so they need to be diluted with water in the recommended proportions. The minus of this product form is the contained additives in the form of flavors and dyes, and even higher cost.
  • Excellent absorption by the body is marked L-carnitine in capsules. It is necessary to accept them, washing down with still water or juice.
  • The most available form of supplement is in tablets, and the price is about 30% lower than liquid. The only difference is that absorption is slower compared to capsules or syrup.
  • The most inconvenient form is the powder that requires dilution in a large volume of water - 0.5 liters. It will take time to calculate the desired dosage. But the effectiveness of the powder is not inferior to the liquid form and has the lowest price.
