L-carnitine plays a powerful role in the process of sperm formation, sperm maturation, and the maintenance of sperm quality. L-carnitine is particularly vital in both the development and maturation of sperm in the testes, in the development of the sperm membrane, and in the metabolic processes as an energy source following ejaculation.
Healthy sperm are defined not just by count, but also by sperm motility and by healthy morphology (sperm shape and size and the integrity of sperm membrane). Sperm motility is determined by the percentage of sperm that are moving and qualified by the sperm’s capacity to "swim" in a sustained, forward direction. Healthy sperm motility is the critical attribute that allows sperm to propel themselves through the uterus to the fallopian tube, penetrate the surface of the ovum, and fertilize the egg.
Carnitine, or L-carnitine, is a naturally occurring substance found in most cells of the body, particularly the brain and neural tissues, muscles, and heart. Carnitine, whose structure is similar to choline, is widely available in animal foods (meat, poultry, fish and dairy products), whereas plants have very small amounts. Most non-vegetarians consume about 100 to 300 mg of carnitine a day, and the body is able to synthesize this nutrient if dietary intake is inadequate. When ingested as a pill, carnitine is not able to cross the blood-brain barrier as well as its activated form Acetyl-L-Carnitine. Acetyl-l-carnitine has a significantly more noticeable effect on the mind than carnitine. Acetyl-l-carnitine usually enhances mental clarity and focus, along with slight mood elevation. The effects of carnitine are more physicial than mental, in the sense that carnitine may provide physical energy whereas acetyl-l-carnitine provides more mental energy.
