Can L-Carnitine be taken orally?

L-carnitine, as a nutritional supplement, can indeed be taken, but it should be used under appropriate conditions and with attention to certain precautions. L-carnitine is not a weight-loss medication; its primary function is to promote fat metabolism and provide energy to the body, with more noticeable effects particularly during physical activity. Individuals aiming to achieve weight loss through L-carnitine supplementation should combine its use with appropriate exercise and dietary control. The dosage of L-carnitine must be controlled, and it is generally recommended to follow the dosage instructions provided by the product or advised by a physician, to avoid potential side effects associated with excessive intake. Special populations, such as pregnant women, lactating women, individuals with serious medical conditions, or those currently taking other medications, should consult a physician before taking L-carnitine.
