Las personas tambi\u00e9n pueden obtenerlo de su dieta o tomarlo en forma de un suplemento oral. La L-carnitina juega un papel cr\u00edtico en la producci\u00f3n de energ\u00eda, ya que convierte la grasa en energ\u00eda.<\/p>\n\n\n\n<p>La mayor\u00eda de las personas obtendr\u00e1n suficiente L-carnitina de su dieta o de la producci\u00f3n de este compuesto por parte de su cuerpo.

Los amino\u00e1cidos se combinan para hacer prote\u00ednas, que llevan a cabo muchas tareas esenciales en el cuerpo. La carnitina ayuda al cuerpo a descomponer los \u00e1cidos grasos y convertirlos en energ\u00eda para alimentar las c\u00e9lulas.<\/p>\n\n\n\n<p>La L-carnitina es un&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/lpi.oregonstate.edu\/mic\/dietary-factors\/L-carnitine\" target=\"_blank\">nutriente condicionalmente esencial,<\/a>lo que significa que el cuerpo generalmente puede hacer suficiente, pero, en algunos casos, una persona puede tener que obtener el compuesto de los alimentos o suplementos orales si no pueden hacer lo suficiente.<\/p>\n\n\n\n<p>En el cuerpo, el h\u00edgado y los ri\u00f1ones crean L-carnitina a partir de los amino\u00e1cidos lisina y metionina.

La L-carnitina es una forma m\u00e1s com\u00fan de carnitina, presente en el cuerpo y en muchos suplementos. Otras formas de carnitina incluyen:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Acetil L-carnitina:<\/strong>&nbsp;Esta forma, a veces conocida como&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/7045767\" target=\"_blank\">ALCAR,<\/a>tambi\u00e9n juega un papel en el metabolismo.

Its&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/ods.od.nih.gov\/factsheets\/Carnitine-HealthProfessional\/\" target=\"_blank\">main function<\/a>, helping break down fatty acids for use as energy, keeps the body\u2019s cells powered and working efficiently.<\/p>\n\n\n\n<p>L-carnitine also has a secondary function of helping remove some waste products from the cells to prevent them from accumulating and causing problems.<\/p>\n\n\n\n<p>In addition to its core functions, L-carnitine may also pose some other&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/ods.od.nih.gov\/factsheets\/Carnitine-HealthProfessional\/\" target=\"_blank\">benefits<\/a>&nbsp;to the body. These include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Heart health<\/h3>\n\n\n\n<p>L-carnitine&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0024320517306525\" target=\"_blank\">may help<\/a>&nbsp;with some markers of heart health, although the research is still ongoing.<\/p>\n\n\n\n<p>Supplementation may help improve L-carnitine levels in a failing heart, which could boost heart health and circulation in the short term following a heart attack. Supplementation may also help with symptoms of heart failure, such as chest pain and arrhythmia.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cancer treatment<\/h3>\n\n\n\n<p>At times, cancer treatments, such as chemotherapy, may cause a person to become deficient in L-carnitine. In these cases, L-carnitine supplements may help&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5795559\/\" target=\"_blank\">reduce symptoms<\/a>&nbsp;such as fatigue and weakness.<\/p>\n\n\n\n<p>Researchers are currently studying the compound as a possible way to prevent tissue damage due to chemotherapy, but this research is in the early stages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Kidney or liver disease<\/h3>\n\n\n\n<p>As the kidneys and liver help create and use L-carnitine, disease in these organs or organ failure may lead to L-carnitine deficiency. Doctors may recommend L-carnitine supplementation in these cases to support the function of the&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/rrtjournal.biomedcentral.com\/articles\/10.1186\/s41100-015-0004-0\" target=\"_blank\">kidneys<\/a>&nbsp;and&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5087626\/\" target=\"_blank\">liver<\/a>&nbsp;and prevent deficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Side effects<\/h2>\n\n\n\n<p>Most people tolerate L-carnitine well. However, some individuals may experience digestive side effects when taking L-carnitine. These&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/ods.od.nih.gov\/factsheets\/Carnitine-HealthProfessional\/\" target=\"_blank\">include<\/a>:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>stomach cramps<\/li><li>nausea<\/li><li>vomiting<\/li><li>diarrhea<\/li><\/ul>\n\n\n\n<p>Some people may also complain of a \u201cfishy\u201d body odor, which is not generally harmful but may be bothersome.<\/p>\n\n\n\n<p>Some&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6047224\/\" target=\"_blank\">studies<\/a>&nbsp;suggest that high levels of L-creatine may raise the long-term risks of cardiovascular diseases, such as&nbsp;atherosclerosis.<\/p>\n\n\n\n<p>L-carnitine supplements may interact with certain antibiotics or anticonvulsants. Anyone considering taking L-carnitine should talk to their doctor to discuss any medications they are taking and the possible drug interactions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How and when to take<\/h2>\n\n\n\n<p>The best amount and form of L-carnitine may vary depending on the person\u2019s reason for wanting more of this compound.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Adults with a good overall health status<\/h3>\n\n\n\n<p>The&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/ods.od.nih.gov\/factsheets\/Carnitine-HealthProfessional\/\" target=\"_blank\">National Institutes of Health (NIH)<\/a>&nbsp;note that healthy people do not need extra L-carnitine from food or supplements. The liver and kidneys will create enough to meet their daily needs.<\/p>\n\n\n\n<p>Even though the body produces it naturally, carnitine is widely available in a number of simple foods. Animal proteins, such as fish, red meat, and poultry, are some of the best sources.<\/p>\n\n\n\n<p>According to the&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/ods.od.nih.gov\/factsheets\/Carnitine-HealthProfessional\/\" target=\"_blank\">NIH<\/a>, adults who eat a mixed diet that includes red meat and other animal products get about 60\u2013180 milligrams (mg) of carnitine per day. People who avoid animal products, such as those following a vegan diet, may get roughly 10\u201312 mg from their diet.<\/p>\n\n\n\n<p>However, the kidneys can store carnitine for later use, so people\u2019s overall levels will be about the same, regardless of their diet. The kidneys also eliminate excess carnitine through urine to maintain healthful concentrations.<\/p>\n\n\n\n<p>Generally speaking, otherwise healthy adults do not need to take L-carnitine to support their health.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Athletes<\/h3>\n\n\n\n<p>Some athletes take extra L-carnitine, believing that it will boost their athletic performance. L-carnitine availability seems to limit muscle metabolism during very high intensity exercise. So, in theory, supplementing carnitine during workouts may support exercise performance.<\/p>\n\n\n\n<p>However, a study in&nbsp;<em><a href=\"https:\/\/www.mdpi.com\/1420-3049\/25\/1\/182\/htm\" target=\"_blank\" rel=\"noreferrer noopener\">Molecules<\/a><\/em>&nbsp;notes that the evidence for this practice is lacking. While many athletes take L-carnitine, years of research does not provide conclusive evidence to support these claims.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For weight loss<\/h3>\n\n\n\n<p>As L-carnitine helps burn fatty acids for energy, many people assume that taking more of it may help them lose weight. More research is necessary, but some studies support this idea.<\/p>\n\n\n\n<p>En una&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/tums.ac.ir\/1395\/05\/20\/28.pdf-olyaeimanesh-2016-08-10-12-57.pdf\" target=\"_blank\">revisi\u00f3n<\/a>&nbsp;de nueve ensayos diferentes, los investigadores encontraron alguna evidencia para apoyar esta afirmaci\u00f3n. Sugieren que los participantes que tomaron L-carnitina perdieron un promedio de 1.3 kilogramos (2.9 libras) m\u00e1s que los que no lo hicieron.<\/p>\n\n\n\n<p>Sin embargo, la L-carnitina no puede reemplazar los h\u00e1bitos saludables, como una dieta adecuada y ejercicio regular.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Recomendaciones de dosificaci\u00f3n<\/h2>\n\n\n\n<p>Las personas que deseen tomar L-carnitina deben hablar primero con un m\u00e9dico. El m\u00e9dico puede tener recomendaciones adicionales para apoyar cualquier tratamiento que la persona necesite y puede ayudarlo a evitar posibles reacciones e interacciones.<\/p>\n\n\n\n<p>La mayor\u00eda de las personas toleran bien la L-carnitina. La dosis recomendada es de aproximadamente&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/label\/2018\/018948s028,019257s014lbl.pdf\" target=\"_blank\">1-3 gramos<\/a>&nbsp;por d\u00eda. Sin embargo, las personas con anomal\u00edas gen\u00e9ticas u otras afecciones que causan una falta de L-carnitina deben hablar con su m\u00e9dico para obtener una dosis m\u00e1s espec\u00edfica.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resumen<\/h2>\n\n\n\n<p>La L-carnitina es un amino\u00e1cido que el cuerpo produce naturalmente. En las personas con buena salud, el h\u00edgado y los ri\u00f1ones producen y almacenan suficiente cantidad del compuesto para prevenir la deficiencia.<\/p>\n\n\n\n<p>Las personas con deficiencias de L-carnitina pueden necesitar obtener el compuesto a trav\u00e9s de su dieta o como suplemento. Es aconsejable hablar con un m\u00e9dico antes de tomar un suplemento de L-carnitina.<\/p>\n\n\n\n<p>Algunas personas pueden desear tomar suplementos de L-carnitina por sus beneficios potenciales, como ayudar al rendimiento atl\u00e9tico o la p\u00e9rdida de peso. Sin embargo, se necesita m\u00e1s investigaci\u00f3n para confirmar estos beneficios.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La L-carnitina, tambi\u00e9n conocida como levocarnitina, es una estructura de amino\u00e1cidos natural que el cuerpo produce.
