Carnitine: A popular fat burner that should have been deposed from the throne long ago
Filomena wanted to lose weight. Filomena bought l-carnitine. The filomena threw up the money. It seems that the carnitine story isn't going to be very positive, is it? Let yourself be surprised. Today we are going to talk about perhaps the most famous fat burner, but it has one important role, but it is not fat burning. So what? Read on.
It is on the legendary throne of burners, but it is wrong. This is the verdict on l-carnitine, about which we begin a little school - the lessons and the basics. It is a compound produced by the body from lysine and methion. It may be acetylated (to form acetyl-1-carnitine, called ALCAR), and at the time it is something similar to classical l-carnitine, but it seems to cross the blood-brain barrier more efficiently. Its function is to transmit fatty acids across the mitochondrial membrane so that they can be oxidized and produce energy.
Carnitine is the Latin word caro, or meat. In chicken, however, it is not so much, dominated by sheep, lamb and beef. The body can absorb l-carnitine from the diet in an amount of about 75%. Of nutritional supplements approximately 5-10%. And you see the first problem here, right?
The boom around carnitine was due to common sense of peasant. It helps with oxidation of fatty acids. However, when I drink a liter of l-carnitine, I burn the fat as hard as the sun's skin at 40 ° C. Unfortunately, this is not true. Unfortunately, no research has confirmed this "peasant theory".
Here he was supplemented by overweight women in aerobic activity. No effects of l-carnitine on fat burning. Even if we look at an independent review on the topic of carnitine fat burning, we find that science does not (unfortunately) support this. Also in Louis Burke's Practical Sports Nutrition book, with many other references, we find that it falls to its knees in terms of fat burning and improving l-carnitine performance. Further investigation of supplements concluded that: “… not enough evidence to recommend carnitine for weight loss or to increase fat oxidation.” The same was true for research on l-carnitine supplementation in caloric deficit. Only on nutritional supplement sites and women's magazines you can find that it burns fats. Right next to an article on detox and a blood group diet. Eh ...
Here and there you read that it also helps in increasing performance. Again, it is only the mindless sentences of copywriters who are in charge of texts on nutritional supplements. In both older and newer research, it is clearly said that l-carnitine cannot move. Even the mix of seventeen investigations did not tell us the positive news. The body simply creates enough and by supplementing it, while increasing the plasma concentration of carnitine (by the way, even when the insulin helper is stimulated more), but not where fatty acid oxidation takes place. In this research, they gave people 4 grams of l-carnitine for three months, and its levels just didn't increase, so don't think you're going to be an exception.
When is l-carnitine supplemented?
# 1 To support the VPVO protocol, ie throwing money out the window.
# 2 If you have any congenital metabolic disorder, damaged liver, you're a hemodialysis patient, you have diabetes mellitus where l-carnitine can help in hyperglycemia and the like. However, 99% of l-carnitine users do not fall into any of these categories, so they only support the VPVO protocol.
# 3 If you want to improve sperm quality for some reason. While many of the data are mixed, a 3g dosage also seems to benefit from this.
# 4 If you have money to spare and you want to test the potential for improving recovery after the performance that some studies are talking about, and for the objectivity of the article, we are talking about it. Minor benefits, if any, are also associated with ALCAR (discussed in the introduction) in improving cognitive functions or in the treatment of Alzheimer and depression.
The recommended dosage is 2-4 g an hour before the procedure. Remember that more is not better. When you reach the saturation point, the additional amount of carnitine works as if you would let a stream of water into a full bottle, with the aim of having more water in it.
Thus, L-carnitine is a supplement that lives from the era of ancient times when farmer's wisdom said it must work. The theory sounds nice, marketing looks splendid, and so was (or still is?) L-carnitine on the throne of fat burners. However, it should have been deposed from it for a long time, since it serves mainly for massive earnings of companies with nutritional supplements.
