It was originally isolated from meat，therefore，It is called a carnitine。The compound has two similar structures，Just like the left hand and right hand mirror，No overlap，They are called L-carnitine and right-converameal。Only L-carnitine can play a role in the human body，L-carnitine is also known as vitaminsBT，It is a naturally occurring compound in human cells。
L-carnitine can be synthesized in human liver and kidney，It can also be supplemented in different types of daily diet in food.5-100MgL-carnitine，L-carnitine in the human body is stored in muscle， semen， Brain and heart。
L-carnitine distribution in almost all cells in vivo，It is related to the human body。Human body needs“fat burning”，That is， When you need to use the energy stored in fat，Fat first is decomposed into fatty acids，then，Fatty acids are transported into cellular mitochondrial“Energy plant”，Oxidation release energy there。Since the mitochondria has a two membrane，Strict structure，Fatty acid itself cannot enter mitochondrial，It is necessary to hitchhiki to enter this car is L-carnitine.。In addition to the L-carnitine transport fatty acid to the mitochondria，It also can transport some hazardous waste generated during the metabolism of the line.。If there is no L-carnitine，Human body does not consume fat with fat to get energy。
There are many statements on the Internet，E.g“L-carnitine can turn fat into lean meat”， “L-carnitine is suitable for lazy weight loss”， “L-carnitine consumes too much fat”， and many more，In fact， This is the misunderstanding of the above process。
L-carnitine is fat“porter”，As for how much fat consumes，It does not rely on L-carnitine。This is why the use of the bricks needed to build buildings in vehicles.。but，How many bricks should be built to consume a building does not depend on the quantity of the car。This depends on the size and structure of the building。
Generally，If the amount of exercise（energy consumption）Not large，Just increase the L-carnitine does not increase fat consumption。Only when the amount of exercise increases，More energy consumption per unit time，L-carnitine“Relatively lack”。at this time，Supplement of L-carnitine supplements，Expand the transport team（Carrier）Scale，More bricks per unit time（fatty acid）Transportation to the construction site（Mitochondrial），Obvious，It helps consume more fat by oxidation。therefore，Only when the amount of exercise is large，Take L-carnitine helps to lose weight。at this time，A large number of exercises is still the key to weight loss，Carnitine only serves auxiliary role。If the amount of exercise is not large，E.g， Just diet weight loss, L-carnitine, no effect on weight loss。
L-carnitine is not diet pills，Its main function is burning fat，Different weight loss and weight loss。In order to reduce the weight of L-carnitine，In addition to burning fat，At the same time cooperate with the appropriate exercise，Control diet。
L-carnitine safety?？Many people are 易彤破壁机维修 worried about facts， Don't worry about using L-carnitine safely than most vitamins。L-carnitine is very safe，Nutrients necessary for human body，Many of the food in nature contains carnitine red meat is the main source of food.，Fishes Poultry and dairy products，Indonesiatemp（From fermented soy）， Wheat and avocado also contain this nutrient。A part of the carnitine needs to be synthesized every day，To meet the needs of human life activities。
Many countries in the world have authoritative reports and regulations on L-carnitine。
in1980Era，Carnitine is sold abroad，And is included《American Pharmacopoeia》First22Version，1984year， Obvious，L-carnitine is very important nutrients。
in1985International nutrition conference held in Chicago， L-carnitine is designated as“Multifunctional nutritional products”。
易彤破壁机常见故障1993American Food and Drug Administration（FDA）The expert committee believes，L-carnitine“It is considered safe and non-toxic。”
1994year， German Ministry of Health，There is no upper limit of the use of carnitine.。
1996year，China's 16th National Food Additive Standardization Technical Committee allows L-carnitine for beverages， Milk drink， Biscuit， solid drink Milk powder。
Currently，There is a world22State and regions allowed to add L-carnitine in infant milk powder，To prevent the lack of carnitine。After the safety test of various countries, the L-carnitine is safe.。
Recommended dose of L-carnitine is daily1-5Gram。If you exceed5Gram， May cause diarrhea。right now， Most literatures suggested additional to an hour before exercise。Aerobic exercise Differential fat effect is very good。You can 易彤破壁机哪款最好 also add a small amount after a meal.。You can't bring it before going to bed.，Otherwise it will affect sleep。
