Dr. Huang Shichang
L-carnitine, a commonly used weight-loss supplement, can promote fat metabolism and burning. However, long-term or excessive use may lead to a series of side effects. The main side effects include:
1. Gastrointestinal dysfunction: Long-term and excessive use may accelerate food breakdown, leading to gastrointestinal disturbances and symptoms such as diarrhea.
2. Reduced sleep quality: L-carnitine breaks down fat to produce energy. Taking it in the evening may cause excitement, resulting in difficulty falling asleep or poor sleep quality.
3. Malnutrition: It may suppress appetite and reduce food intake. Long-term use could lead to anorexia and insufficient nutrient intake, causing malnutrition.
4. Increased heart rate: It has certain effects on the heart, and excessive use may lead to tachycardia, with symptoms such as palpitations and chest tightness.
