Carnitine 500mg (Vegan) - 100 vegetarian free-base liquid capsules | Jarrow Formulas
Jarrow Formulas L-Carnitine (free base) is an amino acid found in high concentrations in heart and liver tissues, where, inside the cells (mitochondria), L-Carnitine helps transform fats into energy.
L-Carnitine also facilitates the metabolism of carbohydrates and enhances the rate of oxidative phosphorylation, the final stage of ATP (i.e., energy) production.
L-Carnitine works synergistically with Co-Q10, an antioxidant and energy cofactor that is found in the inner membrane of the mitochondria.

• helps in restoring normal energy levels at onset physical fatigue
Originally discovered as a growth factor for mealworms and designated a B vitamin, we now understand L-carnitine to be necessary for the generation of metabolic energy in all animals. It is found concentrated in the heart, skeletal muscles, brain, and sperm. Often referred to as an amino acid, L-carnitine is more properly termed a “quaternary ammonium compound.” In human beings, L-carnitine is biosynthesized mainly in the liver and kidneys from the substrates lysine and methionine, with the help of vitamin C, iron, niacin, and vitamin B6.
Even when operating efficiently, the body may produce insufficient levels of L-carnitine to meet cellular demand. This is particularly true during growth and pregnancy. Red meats are one of the best sources of dietary L-carnitine, with few other foods offering more than a smidgen. As such, vegetarians only average a few milligrams daily from dietary sources. But even non-vegetarians often average less than 100 mg per day. That might seem like a lot, but there are some who argue that human beings commonly consumed 500 mg/ day of this nutrient throughout most of pre-history.
Essential for Energy
The primary role of L-carnitine in the body is as a biocatalyst or coenzyme. One of its most important functions is in the oxidation of long chain fatty acids, a process that takes place inside the mitochondria, the “energy factories” of the cells. This process is known as beta-oxidation. L-carnitine is a critical component of the enzyme, acetyl-carnitine transferase, which shuttles fatty acids into the mitochondria and removes waste afterwards. Fats are the preferred source of fuel for skeletal and heart muscle with as much as 70% of the energy generated in muscle coming from the oxidation of fats.
L-carnitine also increases the rate of oxidation of fats in the liver. Because of this, the argument has been made that L-carnitine supplementation during dieting helps to reduce the negative effects of ketosis (the accumulation of waste products of fat metabolism). From animal studies, it’s also clear that L-carnitine can stimulate protection from toxins in the liver.
Athletics: Recovery and Protection
L-carnitine often elicits consideration from athletes, both serious and occasional, for good reason. Research has shown that individuals who supplement with L-carnitine before engaging in exercise are less likely to experience muscle soreness and more likely to experience breathing sufficiency. Double-blind research n this area suggests that 2 grams of L-carnitine taken daily for four weeks leads to positive changes in breathing response during exercise. Nevertheless, not all research on L-carnitine in healthy athletes has found significant effects.
Mechanistically, one way in which L-carnitine may aid the athlete is via antioxidant action in muscle tissue. It’s well understood that the unavoidable byproducts of producing ATP via oxidative phosphorylation are reactive oxygen species (ROS). And ROS levels rise as energy demands rise. This can alter the workings of the cell, especially in athletes, hindering performance and impeding recovery. However, L-carnitine protects the body’s own antioxidant machinery and seems to have direct antioxidant activity itself. Couple this with the fact that L-carnitine is often found in proximity to mitochondria because it is necessary for shuttling fatty acids inside for fuel, and you have targeted ROS protection. As a result, L-carnitine not only may spare antioxidants, such as vitamin C, but also may act directly at the source (i.e. mitochondria) and mop-up high-energy ROS before they rampage through the cell. Such antioxidant protection, particularly against superoxide, is also believed to be at the root of benefits to nerves when exposed to the oxidative stress associated with high blood sugar levels.
