Carnitine is an ammonium compound produced by the liver and kidneys. It serves as a transporter of long-chain fatty acids into the mitochondria to be oxidized for energy production and therefore plays a key role in the regulation of lipid metabolism.

Accordingly, both scientists and sports nutritionists alike have entertained the notion that supplementation could increase the bioavailability of carnitine and enhance the overall capacity for lipid metabolism.

Animal food products like fish and meat are also rich sources of L-carnitine. The name L-carnitine is derived from the Latin word ‘carnis,’ which means meat.

Our body produces L-carnitine and stores it in our muscles and heart tissue, individuals may suffer from a deficiency like vegans, those under undue stress or anxiety, or those with specific genetic issues.

With so many products flooding the supplement industry, it is obvious to get confused while picking the right one for you. Let make us assist you to pick and choose the right one.

Benefits of Carnitine

There is no doubt L-carnitine is the best supplement to burn body fat. But, it does not stop here, it covers all body fat into energy. As your body’s capacity for fat-burning rises, so does your energy level. L-carnitine not only helps you increase the amount of fat burned with every workout, but you also get more energy for better workouts and an active lifestyle. Take a gaze below at some benefits of L-Carnitine Supplement:-

Help to Loss Weight:

L-carnitine’s main role in your body involves mitochondrial function and energy production. In cells, it helps transport fatty acids into the mitochondria, where they can be burned for energy.

Since L-carnitine helps move more fatty acids into your cells to be burned for energy, you might think this would increase your ability to burn fat and lose weight.

Improve Heart Health:

L-carnitine is also linked to improvements in patients with severe heart disorders, such as coronary heart disease and chronic heart failure.

In one study, 2 grams of acetyl-L-carnitine per day resulted in an almost 10-point drop in systolic blood pressure — the top number of a blood pressure reading and an important indicator of heart health and disease risk.

Increase Athletic Performance:

The evidence is mixed when it comes to L-carnitine’s effects on sports performance.

However, several studies note mild benefits associated with larger or more long-term doses.

L-carnitine may benefit:

  • Recovery: May improve exercise recovery.
  • Muscle oxygen supply: May increase oxygen supply to your muscles.
  • Stamina: May increase blood flow and nitric oxide production, helping delay discomfort and reduce fatigue.
  • Muscle soreness: May reduce muscle soreness after exercise.
  • Red blood cell production: May increase the production of red blood cells, which transport oxygen throughout your body and muscles.

Side Effects

L-carnitine is safe like other supplements. But high dosage can cause side effects such as stomach upset, heartburn, diarrhea, and seizures. It can also cause the urine, breath, and sweat to have a “fishy” odor. Avoid using D-carnitine and DL-carnitine. These forms of carnitine might block the effects of L-carnitine and cause symptoms that resemble L-carnitine deficiency.

Recommended Dosage

L-carnitine has most often been used by adults in doses of 2 grams by mouth daily. In children, L-carnitine has most often been used in doses of 50-100 mg/kg by mouth daily, for up to one year. Speak with a healthcare provider to find out what dose might be best for a specific condition.

When is the best time to take L-carnitine?

As suggested by medical experts and bodybuilders, the best time to take L-carnitine is after a workout. You should be careful if you want to stack L-carnitine with other fat-burning supplements. In this case, it is best to take the acetyl-L-carnitine form of it.
