Carnitine
Carnitine Supplements are commonly presented & sold as Formulated Supplementary Sports Foods in New Zealand – L-Carnitine or just carnitine is one of the most well known fat loss supplements on the market today. In the body, L-carnitine is made from the two amino acids lysine and methionine, but can also come from a variety of food sources such as milk, but generally in very small quantities. L-carnitine functions to transport fatty acids from the blood into mitochondria, cells in muscles which utilise fats to create energy for physical activity and exercise. In times of intense exercise, the need for L-carnitine increases which means you should have adequate supply of not only the two amino acids lysine and methionine, but also vitamin C, iron, Vitamin B6 and niacin. This makes L-carnitine a great supplement for those following a low-calorie diet or those who don’t eat much red meat, poultry, dairy or seafood, but still participate in plenty of physical activity. The benefits of L-carnitine use are greater when used for a prolonged period of time and in combination with regular exercise and an appropriate diet. Research from Spain found that carnitine supplementation for 6 months helped reduce training-associated drops in carnitine levels. L-carnitine is an excellent supplement for endurance athletes such as soccer/football players, rugby players and runners as it can help to improve recovery times and reduce prolonged muscle soreness2. Studies have been able to show that L-carnitine can increase the use of fat for energy and with carnitine supplementation, users can expect protection against its depletion in the body and thus improve the body’s ability to deliver oxygen to the working muscles during and post-exercise.3
Besides its ability to promote fat burning and fat used as energy, carnitine helps to prevent drops in testosterone levels which occurs after a period of physical and mental stress such as during a strict training and diet routine. Studies have been able to show that L-carnitine can promote the activity and the number of cells in the brain which are responsible for activating the pathway for testosterone production. Research presented at the 25th US National Strength & Conditioning Association conference showed that Carnitine (2 grams daily) can be highly effective for increasing testosterone levels4,5. What's more, this level of L-carnitine has been effective at reducing the level of muscle damage and soreness after a bout of exercise. A trial published in the respected American Journal of Physiology was able to show that muscle damage and negative changes post-exercise could be reduced by up to 50% with Carnitine supplementation3. Other markers of muscle damage can also be reduced with the authors commenting that there was "...less accumulation of markers of purine degradation, free radical formation, tissue damage, & muscle soreness." The study was able to show that larger doses of L-Carnitine (500-2,500 milligrams) are more effective than smaller amounts (50-100 milligrams).
Unlike the essential vitamins and minerals, there is no recognised recommended daily intake of L-Carnitine. However as previously mentioned, a daily intake of 500-2,500 milligrams should be sufficient to hep prevent the deleterious effects of exercise. Some studies were able to show 1g/day works just as well than 2g/day of L-carnitine supplementation6. People using carnitine may expect improvements in their energy levels after 7-10 days with improvements in the level of muscle soreness being the biggest difference felt. Several weeks however are required in order to observe clearly L-carnitine’s potential effect on fat loss and testosterone levels. L-carnitine can work well on its own, but can also easily be stacked with phosphates for better endurance as well as other supplements for recovery including BCAAs (branched chain amino acids), creatine and protein. There are few side effects from the use of L-carnitine with the most common ones being increased appetite, potential diarrhoea and the appearance of a rash. However, most of these symptoms occur at doses in excess of 5g/day, more than double the amount required to elicit beneficial effects.
Carnitine is not a sole source of nutrition and should be used in conjunction with an appropriate physical training or exercise programme. Not suitable for children or pregnant women. Should only be used under medical or dietetic supervision. Always read the label prior to use.
