Best L-Carnitine Supplement - The Detox Guy Recommendations

Best L-Carnitine Supplement for Detox Diet

L-carnitine Rich Foods

In our 28 days Detox Plan L-Carnitine will be a helper to speed it up your weight loss.

L-carnitine is a naturally occurring amino acid derivative that’s often taken as a weight loss supplement. It plays a crucial role in the production of energy by transporting fatty acids into your cells’ mitochondria. The mitochondria act as engines within your cells, burning these fats to create usable energy.

Your body can actually produce L-carnitine out of the amino acids lysine and methionine. For your body to produce it in sufficient amounts, you also need plenty of vitamin C. In addition to the L-carnitine produced in your body, you can also obtain small amounts from the diet by eating animal products like meat or fish (5).

What are L-Carnitine Functions?

L-carnitine is an amino acid that performs three very important functions that enhance athletic performance:

  1. L-carnitine is THE nutrient, the “ferry” so to speak, that shuttles fatty acids from the blood into the mitochondria, the energy producing “furnaces” in the cells, so that the fatty acids can be used as energy. If you want to use fat as a fuel as efficiently and effectively as possible, you need l-carnitine.
  2. L-carnitine also helps improve endurance by inhibiting the build-up of lactic acid, one of the primary causes of fatigue.
  3. L-carnitine has also been shown to reduce the accumulation of metabolic wastes during exercise. This helps increase workload output during exercise and enhancing recovery post-exercise.

L-Carnitine Recommended Dosage

Athletes can safely consume l-carnitine in supplement form to justify replacement. If you are consuming supplemental l-carnitine, we recommend keeping your totals in the range of 2000 mg (2g) per day.

A non-athlete who consumes large amounts of meats that contain l-carnitine does not need to supplement this substance. Animal meat not only generates bodily carnitine, it also generates a protein structure that drives weight gain, growth factors, and plaque formation. If not derived from naturally raised grass-fed animals, there are other harmful substances found in meats that over time may prove harmful to health.

Overall, we recommend not over consuming substances from the animal kingdom that drive cholesterol accumulation on artery walls.

L-Carnitine Rich Food Sources

Animal products like meat, fish, poultry, and milk are the best sources. In general, the redder the meat, the higher its carnitine content. It can also be found in small amounts in some sources like vegetables and grains.

  • Beef steak, cooked, 4 ounces: 56–162 milligrams
  • Ground beef, cooked, 4 ounces: 87–99 milligrams
  • Whole milk, 1 cup: 8 milligrams
  • Codfish, cooked, 4 ounces: 4–7 milligrams
  • Chicken breast, cooked, 4 ounces: 3–5 milligrams
