L-Carnitine: What it is for, benefits, and how to take it
Compartir
Although the body produces L-Carnitine, the amount generated is not always enough to optimize fat burning or improve physical performance, especially in people with diets low in certain nutrients (such as vegetarians) or during intense training.
For this reason, many people turn to L-Carnitine supplements to enhance its effects.
L-Carnitine is also found in foods, mainly of animal origin. Some rich sources include:
- Red meat: beef and lamb (approximately 80-120 mg per 100 g).
- Poultry: chicken (3-5 mg per 100 g).
- Fish: cod and salmon (5-10 mg per 100 g).
- Dairy: milk and cheese (2-10 mg per 100 g).
Plant-based sources, such as avocados or asparagus, contain minimal amounts, which explains why vegetarians or vegans can particularly benefit from supplements.
What is L-Carnitine used for?
The main function of L-carnitine is to facilitate the oxidation of fats in the mitochondria to produce energy. This makes it a popular supplement for:
- Fat burning: L-carnitine transports fatty acids to the mitochondria, where they are converted into energy. This helps reduce fat deposits, especially during aerobic exercise.
- Improved athletic performance: by preserving muscle glycogen (the main source of fast energy), L-carnitine allows for longer and more intense training.
- Muscle recovery: studies suggest that L-carnitine reduces muscle damage and post-exercise inflammation, accelerating recovery.
- General health support: it can benefit the liver, heart, and male fertility by improving sperm motility.
L-Carnitine is like a vehicle that transports long-chain fatty acids to the mitochondria. Once there, these acids are oxidized (burned) to produce energy in the form of ATP. This process is especially active during exercise, when the body needs more fuel. In addition, L-Carnitine:
- Spares glycogen: by prioritizing fats as an energy source, you preserve glycogen reserves, improving endurance.
- Reduces fat accumulation: by promoting lipid metabolism in the liver, it prevents the formation of new fat deposits.
- Improves energy efficiency: optimizes energy production, which can result in less fatigue during exercise.
Ideal time to take L-Carnitine
- 30-40 minutes before exercise: taking L-carnitine before training maximizes its absorption and effectiveness, as the body will be in an active fat-burning state.
- On an empty stomach (optional): some experts suggest taking it in the morning with water or juice to take advantage of the insulin peak, which facilitates its transport to the muscles.
- Post-workout (less common): it can aid in muscle recovery when combined with carbohydrates.
L-Carnitine format
L-carnitine is available in various formats, with the liquid presentation being the most recommended, as its absorption is faster, easy to transport, ideal for taking before exercise. It is recommended to dilute in 150 ml of water.
Practical tips to maximize the benefits of L-Carnitine
- Combine with a balanced diet: make sure you consume enough protein and carbohydrates to support energy metabolism.
- Maintain an exercise routine: prioritize 30-60 minute moderate cardio sessions 3-5 times a week.
- Stay well hydrated: L-carnitine works best in a well-hydrated body.
- Choose quality brands: look for supplements with purity certifications and no unnecessary additives.

Consult a specialist: a nutritionist can personalize the dosage and intake time according to your needs.
L-carnitine is a versatile supplement that can help you burn fat, improve your athletic performance, and support your general health when combined with exercise and a proper diet. Although it is not a miraculous solution, its ability to optimize fat metabolism makes it a valuable tool for athletes, people in weight loss processes, and those with nutritional deficiencies.

To get the best results with L-carnitine in your training routine, it is important to take it at the right time and in the right way. Consuming it before exercising can boost fat burning during physical activity and improve your performance. Don't forget to consult a professional to personalize the dosage and ensure that this supplement fits your specific needs.
An important message: Talk to your specialist.
It is important to consult a healthcare professional before starting to take any supplement, especially if you have pre-existing medical conditions or are undergoing treatment with medications.
