L-Carnitine and N-acetyl-cysteine for Reproductive Health

L-carnitine and the closely related acetyl-L-carnitine are both important components of cellular respiration. In these roles they are required for the transport of fatty acids (actually acyl CoA) into the mitochondria in order to allow beta oxidation and energy release … Continue reading

Aspartate, Asparagine, and Carnitine Supplementation

Aspartate, asparagine, and carnitine have been investigated for their beneficial effects on exercise. Aspartate and asparagine are precursors to oxaloacetate which may play a role in fatty acid oxidation via the citric acid cycle. In addition, carnitine is important for … Continue reading

L-Carnitine, Testosterone and Recovery

L-carnitine is a naturally occurring compound found in high concentrations in muscle tissue. One of the main physiological functions of carnitine is to transport fatty acids into the mitochondria for oxidation. However, carnitine may have a number of other functions … Continue reading

L-Carnitine for Cognition

Evidence from cell culture studies shows that L-carnitine and acetyl-L-carnitine (ALC) have neuroprotective effects. This is also supported by evidence from animal studies, for example using rats. The mechanism of action may involve neuroprotection through a decrease in neurotoxicity as … Continue reading

Carnitine as an Anti-Aging Supplement

Evidence suggests that male androgen levels drop somewhere around 1.2 % per year for free testosterone between the ages of 39 to 70. Further, albumin bound testosterone drops 1 % per year and total testosterone drops 0.4 % per year. … Continue reading

L-Carnitine: Main Functions

L-carnitine is a nutrient factor found mainly in foods of animal origin that plays a role in the use of fat as an energy source. Humans can also synthesise L-carnitine (L-b-hydroxy-c-N-trimethyl aminobutyric) acid in the liver, brain and kidneys from … Continue reading

The Effects of L-Carnitine Supplements on Weight Loss

L-carnitine is a nutrient factor that is present in the diet but also synthesised by cells. One of the functions of L-carnitine is to shuttle fatty acids into the mitochondria where they are oxidised to produce energy. Some evidence suggests … Continue reading

L-Carnitine and Lipoproteins

The oxidation of fatty acids occurs in the mitochondria, but fatty acids are unable to cross the inner mitochondrial membrane unaided. L-carnitine is involved in the shuttle system that allows fatty acids to cross this inner membrane which allows β-oxidation … Continue reading
