"L-carnitine" - L-carnitine, L-carnitine, also known as L-carnitine, vitamin BT, chemical name β-hydroxyγ-trimethylammonium butyric acid, is a white lens or white transparent fine pink. Research on carnitine began in the early 20th century. In 1905, Russians Gulewitsch and Krimberg discovered L-carnitine from meat extracts. Since then, scientists from various countries have conducted in-depth research. Early studies found that L-carnitine is a vitamin-like nutrient and has been Named Vitamin BT. In fact, the chemical structure of alkali is similar to choline and similar to amino acids; in addition, because some animals can synthesize it by themselves to meet the needs of carnitine, it is considered that carnitine is not a vitamin, but it is still customarily called vitamin BT. Experiments have shown that carnitine is an essential nutrient. At the International Nutrition Academic Conference held in Chicago in 1985, L-carnitine was designated as a "multifunctional nutritional product."
At present, L-carnitine has been used in the fields of medicine, health care and food, and has been designated as a legal multi-purpose nutritional supplement by Switzerland, France, the United States and the World Health Organization. my country's food additive health standard GB2960-1996 stipulates that L-carnitine tartrate is a food nutrition fortifier that can be used in chewable tablets, drinking liquids, capsules, milk powder and milk drinks, etc.
L-carnitine is easy to absorb moisture, has good stability and can be left in a solution with pH 3 to 6 for more than 1 year. It can withstand high temperatures above 200°C and has good water solubility and water absorption. L-carnitine in the diet mainly comes from animals, and the content in plants is very small: rich sources include lean meat, liver, heart, yeast, chicken, rabbit meat, milk and whey, etc.; good sources include avocado, cheese Egg whites and malt, etc. People who are fasting, vegetarian, strenuous exercise, obese, pregnant, male infertility, and babies who eat formula without fortified carnitine are prone to carnitine deficiency. Low dietary lysine, vitamins and iron content also lead to carnitine deficiency. Many patients such as heart disease, hyperlipidemia, kidney disease, liver cirrhosis, malnutrition, hypothyroidism, and certain muscle and neurological diseases have generally low carnitine levels. L-carnitine supplementation mainly relies on exogenous supplementation, and carnitine supplementation is as important as vitamin and mineral supplementation.
Muscle movement relies on your body's ability to convert fatty acids into energy. L-carnitine is an essential amino acid that enables this transformation. Different types of daily diets already contain 5 -100 mg of L-carnitine. L-carnitine is produced in the body's liver and kidneys and stored in muscles, semen, brain and heart. Some people do not properly get enough from their dietL-carnitine, causing a deficiency of this nutrient. As a result, they may slowly develop heart disease, muscle weakness, or low blood sugar.
