Potential Benefits
L-carnitine plays a critical role in energy production by transporting fatty acids into the mitochondria where they are burned for fuel.
- Energy Metabolism & Weight Management: It helps the body use fat stores as an energy source, which may aid in weight loss and increase calorie expenditure, especially when combined with exercise.
- Exercise Performance & Recovery: Supplementation can support endurance performance, reduce muscle damage and soreness, and speed up recovery after intense physical activity.
- Heart and Brain Health: L-carnitine is important for heart and brain function. It may help improve symptoms in people with heart conditions and enhance cognitive function, particularly the acetyl-L-carnitine form.
Important Considerations
- Dosage: L-carnitine has most often been used by adults in doses of 2 grams (2000 mg) daily by mouth. The 600mg dose is a common serving size, and the number of tablets or capsules required to reach optimal dosage may vary by product.
- Side Effects: When taken by mouth, L-carnitine is likely safe for up to 12 months. Side effects can include stomach upset, heartburn, diarrhea, and a “fishy” body odor.
- Interactions: L-carnitine might increase the effects of blood-clotting medications like warfarin and acenocoumarol, and may decrease the effectiveness of thyroid hormone.
- Consult a Healthcare Provider: It is recommended to consult a doctor, especially if you are pregnant, nursing, have a medical condition, or are taking other medications, to determine the appropriate dosage and ensure safety.
