Carnitine Supplements - what you should know!

Whether you are looking to lose fat or gain muscle, taking carnitine supplements can help you achieve your goals in the gym by speeding recovery time and giving you more energy in your day to day life.

Carnitine is found naturally in the human body and is responsible for converting fat stores into energy to be used by muscles. Increasing your levels of carnitine can result in improved athletic performance and physique by reducing body fat and increasing muscle mass.

Carnitine can also be used in conjunction with traditional medical treatments for people suffering from a wide range of conditions such as heart disease or other cardiovascular problems, as well as kidney disease, overactive thyroid, and fertility problems in males.

What is Carnitine?

Carnitine is a type of amino acid produced naturally in the body by the liver and kidneys. It is found in high concentrations in red meat, and at lower levels in dairy products, cod fish and numerous vegetables.

For those who cannot produce enough carnitine or have difficulty consuming enough to meet their requirements, supplements may be useful in preventing a carnitine deficiency. For athletes and recreational gym goers, carnitine can help increase energy levels and muscle development, as well as promote fat loss.

There are two main types of carnitine: L-Carnitine and Acetyl-L-carnitine. Both these types of carnitine are safe when taken as oral supplements in dosages between 500 and 1,000 mg per day.

Carnitine health benefits

  • Improved athletic performance and endurance
  • Muscle growth
  • Bone mass growth
  • Fat loss
  • Increase in levels of mental clarity and alertness
  • Improvement of a range of heart conditions such as angina, congestive heart failure, and circulation problems
  • Prevention of heart attack reoccurrence
  • Improvement of red blood cell count in people with kidney disease
  • Reduction of symptoms associated with an overactive thyroid gland
  • Increased sperm count in males with fertility problems

Carnitine supports energy

Carnitine increases energy and stamina levels by encouraging the body to burn fat as fuel, saving the glycogen stores in the liver until they are absolutely necessary.

Taking carnitine supplements gives the muscles additional energy they would otherwise not have access to, which results in increased stamina and endurance in aerobic activities. Other positive effects are a reduction in muscle fatigue and a decrease in recovery time, all of which will help you feel more energized as you go about your day.

In addition to the physical effects, carnitine benefits mental alertness and concentration. Studies have shown that carnitine can also help prevent age related cognitive impairment.

Carnitine and weight loss

Carnitine can speed up weight loss and help your body burn fat quickly by transporting energy from fat stores to be consumed by your muscles.

When you increase carnitine levels, you increase the speed and efficiency with which your body burns fat. It also increases stamina and endurance levels, meaning you have the energy to burn more calories and undertake longer, tougher workouts on a more regular basis.

Carnitine can also help reduce levels of dangerous, visceral fat stored around the belly. This results in lower levels of cholesterol and decreases the risk of developing atherosclerosis, also known as clogged arteries.

Carnitine and the cardiovascular heart

In addition to conventional treatments for heart conditions, carnitine can be a useful supplement for a range of cardiovascular health issues. Carnitine benefits those suffering from angina and can help reduce chest pain during exercise.

Studies have also shown that the intake of carnitine supplements shortly after a heart attack can reduce the risk of another one occurring. Carnitine assists in reducing cholesterol levels and can help protect against the development of heart disease.

Carnitine can also be used as a treatment for other conditions of the heart and blood vessels such as circulation problems, congestive heart failure, myocarditis (inflammation of the heart) and complications from diphtheria.

Carnitine for exercise and recovery

Taking a supplement of carnitine reduces levels of muscle fatigue and soreness associated with undergoing a strenuous exercise or gym routine. This results in a decrease in the required recovery time between workout sessions and can help you achieve your strength and fitness goals much more quickly.

Studies have shown that a carnitine dosage of 1000 mg per day is effective in improving levels of muscle stress markers hypoxanthine, xanthine oxidase, myglobin, and general inflammation and soreness levels in response to strength training exercise.
