L-carnitine and its roles:
- Supports energy production
- Helps regulate lipogenesis
- Reinforces osteoblasts activity
- Supports sperm viability and motility
Carnitine, as its active isomer (L-carninite form), is a transporter molecule, synthesized from a base of lysine and methionine, in a process where vitamin C works as a cofactor. It allows the transportation of fatty acids chains from the cytosol to the mitochondria. These fatty acids will be used as an energy source in the ß-oxidation.
Horses at rest do not appear to need carnitine but during intensive work, the reserve can decrease rapidly, and the liver and kidney syntheses are slowed down. Endurance horses are a target population for a supplementation in this element.
