L-carnitine 左旋肉碱250mg 100颗

左旋肉碱支持心脏肌肉功能或骨骼肌的性能，是心肌和骨骼肌必须的脂肪酸代谢和能量生产。它参与脂肪酸氧化的肉碱穿梭的一部分。左旋肉碱穿梭脂肪酸从细胞质（细胞液）进入线粒体（细胞的发电站）的氧化和能源生产。大约一个小时的连续剧烈运动，如长跑，骑自行车，游泳，或登山后会发生。广泛分布于从动物性食品。

约95％人体的左旋肉碱位于骨骼和心脏肌肉。左旋肉碱被认为是一种必需营养素。在健康人群中，血浆中的L-肉碱的水平是由人体自身合成和膳食来源充分保持。然而，低左旋肉碱血浆水平可以通过遗传性（原发性）L -肉碱缺乏症，或者通过二次左旋肉碱缺乏症引起的。

口服左旋肉碱是到达整个肠黏膜而进入血液易被人体吸收，然后进入肝脏，并随后被释放进入身体循环。大多数细胞都有特定的肉碱运转。

Douglas Laboratories’ L-Carnitine supplements supply pure, natural L-Carnitine in capsule form.


L-Carnitine may be a useful nutritional adjunct for individuals who wish to support heart muscle function or skeletal muscle performance.


L-Carnitine is necessary for fatty acid metabolism and energy production in cardiac and skeletal muscle. It is involved in fatty acid oxidation as part of the carnitine shuttle. L-Carnitine shuttles fatty acids from the cytosol (the cell fluid) into the mitochondria (the cell’s powerhouses) for oxidation and energy production. L-Carnitine is necessary in muscle whenever fat is utilized as an energy source. Heart muscle always uses fat for its continuous energy demands. Skeletal muscle begins using fat only after its glycogen reserves are exhausted.


This happens after about one hour of continuous, strenuous exercise, e.g., long-distance running, bicycling, swimming, or mountain climbing. Widely distributed in foods from animal, but not plant sources, L-Carnitine is also synthesized by the liver and kidney from two essential amino acids, lysine and methionine. Human skeletal and cardiac muscles contain relatively high L-Carnitine concentrations which they receive from plasma, since they are incapable of L-Carnitine biosynthesis themselves.


About 95 % of the body’s L-Carnitine stores are located in skeletal and heart muscle. L-Carnitine is considered a conditionally essential nutrient. In healthy people, plasma L-carnitine levels are adequately maintained by the body’s own synthesis and dietary sources. However, low L-Carnitine plasma levels can be caused by hereditary (primary) L-Carnitine deficiency syndrome, or by secondary L-Carnitine deficiency. Patients with heart failure excrete large amounts of L-Carnitine in their urine. Oral L-Carnitine is readily absorbed across the intestinal mucosa and into the bloodstream.


It is then taken up from the portal vein into the liver and subsequently released into the systemic circulation. Most cells have a specific carnitine transporter. Dietary L-Carnitine comes mainly from animal foods. Average non-vegetarian diets provide about 100 to 300 mg of L-Carnitine per day. Vegetarian diets often provide only trace amounts, since vegetables, fruits, and cereals are negligible sources of L-Carnitine.
