First what is L-Carnitine? L-Carnitine is a natural nutrient also used to be known as vitamin BT. L-Carnitine is a physiological substance, essential for energy production and for fat metabolism. L-Carnitine can be synthesized in the human liver, but insufficient amounts may be produced in infants, in adolescents and in adults under certain physiological conditions.
Where does L-Carnitine come from? L-carnitine, also known as carnitine, is made in the liver and kidneys. It is a quaternary ammonium compound synthesized from the amino acids lysine and methionine and performs some of the same functions, such as helping metabolize food into energy, transportation of fatty acids and consumption and disposal of fat in the body.
What are the Benefits of L-Carnitine in sports? L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria (a cell’s energy powerhouse), where they may be oxidized, releasing energy. L-carnitine is a very popular supplement that promotes fatty acid metabolism as well as growth and development. It is also used for fat-burning, increasing energy, and improving resistance to muscle fatigue. L-carnitine also helps to build muscle. It also helps to transport the toxic byproducts of energy composition out of the mitochondria to prevent accumulation.
What foods are high in L-Carnitine? The following foods contain a high concentration of L-Carnitine
L-Carnitine is found primarily in red meats (especially lamb and beef) and dairy products.
Please note that these foods do not contain enough L-Carnitine to be realistically considered as a method of L-Carnitine supplementation.
What is Acetyl-L-Carnitine, what does it do and how does it differ from L-carnitine? Acetyl-L-carnitine is simply an acetylated form of L-carnitine. It is claimed to provide several benefits including life extension. There may be some benefit in cases of end stage renal disease or peripheral arterial disease. When supplemented alongside Lipoic acid, it appears to reverse some of the damage to mitochondria associated with aging.
Turning up your metabolism with the right nutrients is essential for weight loss. There is significant evidence that increased levels of carnitine in tissue leads to increased fat burning.
The sports performance drink I use and recommend has:
- It contains 375 mg of L-Carnitine to aid in burning fats for energy.
- It also contains caffeine from green tea
- It contains all the ingredients necessary for energy production such as malice acid, citric acid, Korean ginseng, rhodiola, and others.
- It has 70 calories per serving which are very low glycemic, so like other sports drinks which have simple sugars which lead to the sugar crash, Rev3 won’t let you down midway through your run, ride, or workout.
- One client in marathon training was doing a 12 mile training run. She drank a Rev3 before heading out and found that she was on a record pace and that she beat her best 12 mile run by two minutes.
- Another client was training for the same marathon did a 20 mile run. She completed the 20 miles 2-1/2 minutes better that her best time. She said mile by mile she was ahead her best time through about 12-23 miles then fell back to just above her regular pace, but never crashed.
- Bob is 58 and an avid bike rider. He did a ride from Boulder to the summit in Rocky Mountain National Forest, a 120 mile round trip. Though he didn’t time his ascent he was the first one to the summit in his group by 10 minutes – normally he is towards the end of the pack. His group tried to keep up with him but non could – some were 30 years younger too!
- There are a number of medal winning Olympic athletes who use Rev3.
