L-carnitine is a kind of amino acid that promotes the conversion of fat into energy. The correct use of L-carnitine generally has no toxic side effects on the human body. The main effects and effects include weight loss, enhancing endurance and anti-fatigue, and maintaining infant body functions. 1, weight loss: L-carnitine as an essential coenzyme in fat metabolism, can promote the metabolism of human fat, speed up the burning of fat, so as to assist in weight loss. At the same time, when the human body after a long period of intense exercise, the L-carnitine transport capacity in the body will also be enhanced to further accelerate the burning and oxidation of their own fat, to achieve the ideal fat burning and weight loss effect; 2, enhance endurance and anti-fatigue: L-carnitine can improve the oxidation function of the human body by changing the activity of respiratory enzymes in the mitochondria to a certain extent, thereby helping to enhance the muscle endurance of the human body itself. At the same time, the use of L-carnitine after exercise can help delay the appearance of muscle fatigue symptoms, eliminate excessive lactic acid in the body, thereby improving exercise ability; 3, maintain the baby's body function needs: L-carnitine as an important substance to promote the conversion of fat into energy, belongs to the baby's essential nutrients, can maintain the physiological development of the baby's body, many infant milk powder on the market has added L-carnitine; 4, other effects and effects: When the body's high density cholesterol increases, L-carnitine can help reduce the blood triglyceride and cholesterol levels, minimize its damage. L-carnitine is also an energy substance for sperm maturation, which can help improve sperm motility and quality to a certain extent. 左旋肉碱是促使脂肪转化为能量的一种类氨基酸，正确使用一般对人体没有毒副作用，主要作用与功效包括减肥、增强耐力与抗疲劳、维持婴儿身体机能所需等。 1、减肥：左旋肉碱作为脂肪代谢中的必需辅酶，能够促进人体脂肪的代谢，加快脂肪的燃烧，从而起到辅助减肥的效果。同时，当人体长时间剧烈运动以后，体内的左旋肉碱转运能力也会增强，以进一步加快自身脂肪的燃烧以及氧化，达到理想的燃脂瘦身效果； 2、增强耐力与抗疲劳：左旋肉碱能够通过在一定程度改变线粒体内呼吸酶的活性，提高人体的氧化功能，从而帮助增强人体自身肌肉耐力。同时，运动后使用左旋肉碱，可以帮助延缓肌肉疲劳症状的出现，消除体内过多的乳酸，从而提高运动能力； 3、维持婴儿身体机能所需：左旋肉碱作为促使脂肪转化能量的重要物质，属于婴儿必需营养成分，能够维持婴儿身体生理发育，市面上不少婴幼儿奶粉里已经添加左旋肉碱； 4、其它作用与功效：当人体高密度胆固醇增加时，左旋肉碱可以帮助减少血中三酸甘油脂及胆固醇水平，尽量减少其损害。左旋肉碱还是精子成熟的能量物质，能够在一定程度帮助提高精子活力与质量。
