l-carnitine swept the whole country, but just a weight-loss supplements, exercise ineffective enough, is not high purity may also cause muscle atrophy.
Beijing to start is not high, weight is more than more than 160 pounds, eat slimming diarrhea leading to dehydration, lying in bed a few days up to; buy abdominal muscle weight-loss devices, earthquake was numb, to no avail; Buy treadmills, insist on down, has been idle. Later, suffering from diabetes, Peking Union Medical College hospital after diagnosis, prescription only out of the 8 characters: Diet, adequate exercise.
with the increase of obesity, weight-loss market rapidly warming, variety of diet have on stage, cohabitation, consumers difficult to true or false. Last year, a Dr TV strongly recommend a place in the l-carnitine, l-carnitine moments become a weight-loss star product, is scrambling to snap up.
reporter in Taobao search, found nearly 50,000 products. Some shops even months sales reached more than 2000 pieces. This reporter interviewed several pharmacies, staff said that l-carnitine products sell very well.
eat weight loss product knows that, weight-loss drugs, health products are some side effects, such as dry mouth, diarrhea, not sleep, so buy weight loss products are more cautious. But the effect of l-carnitine publicity safe without side effects.
This really true? Peking Union Medical College hospital after Deputy Chief Physician of the Department of Endocrinology Pan Hui studies found that l-carnitine is a type of amino acid of fat into energy, derived from red meat, non-toxic side effects to the human body. Main physiological function is to promote fat into energy, in the 2003 International Health Organization identified as the most safe and without side effects of obesity weight loss supplements.
in practice, however, l-carnitine is a means of delivery, like transport of fat. As to exactly how much fat, does not depend on l-carnitine. Simply put, if physical activity is small, fat little only increased l-carnitine, and does not increase fat oxidation function, so no help to lose weight.
Pan Hui pointed out that purity is not high l-carnitine products be detrimental to muscle build, even causing muscle weakness, muscle atrophy, and so on. He explained that the carnitine exists in nature, there are two forms of d-carnitine and l-carnitine. The only difference between the two is structurally symmetrical to each other, but the study found no effect not only of d-carnitine, also harmful to the muscle generates, can cause muscle weakness, muscle atrophy, and so on. Method to produce the chemical synthesis of carnitine, usually is a mixture of l-and d-carnitine, and separation method of d-carnitine separated from l-carnitine to produce l-carnitine. Due to the cost of extraction of l-carnitine complex, expensive, most of the current application of l-carnitine is an industrial production, and if the purity is not high, which may contain a certain amount of harmful impurities other than l-carnitine.
many colon, Enterprise, OEM counterfeiting products, exaggerating the effect means false propaganda used; and even formal irregularities also added a Western drug ingredient and to meet the needs of people within a few days to operate.
last September, the State administration for industry and Commerce serious illegal food advertising exposure, labeled product name "West wood l-carnitine milk tea" food ads ranked.
reporter landing State food and Drug Administration website, found only two products have a lot of l-carnitine, respectively for the country's food and health G20080575 bechen l-carnitine tea polyphenols capsule, State food and health G20080650 aoluna l-carnitine capsules of Ginkgo biloba.
however, even the legitimate products, also added illegal drug phenomenon.
