Carnitine is a nutrient produced by the liver and kidneys and stored in the skeletal muscles, heart, brain and sperm. Carnitine allows the body to turn fat into energy, according to the University of Maryland Medical Center. Deficiencies in this nutrient can be inherent if the body does not produce or transport the nutrient appropriately or can be caused by some medical conditions and medications. Supplementing with L-carnitine can be used in some medical conditions but should always be prescribed and monitored by a physician, especially in children.
Function
Carnitine helps move fat into the cells where it is then burned for energy. Once the fat has been converted to energy, carnitine is also responsible for moving the residue from the fat out of the body. This is accomplished when carnitine binds to the residue and then dissolves in the urine, thereby ridding the body of the residue and recycling the carnitine for future use, according to FodSupport.com.
Deficiency in Children
Carnitine deficiency is typically seen as a secondary issue related to other health problems. Children with small muscle mass, which can be caused by cystic fibrosis and kidney disorders, often require carnitine supplementation. Genetic metabolic disorders that affect fat oxidation can also lead to carnitine deficiency because it is often excreted in the urine.
Supplementing with L-Carnitine
The Food and Drug Administration has approved the use of L-carnitne for treating deficiencies secondary to other medical conditions. L-carnitine can be taken orally or intravenously and should only be used when prescribed by a physician.
Safety & Side Effects
L-carnintine has a few side effects. A body odor has been reported as well as stomach upset and diarrhea. L-carnitine can also interact with certain medications and herbal supplements you might be taking, making it important to inform your physician of all medications and supplements being used at the same time, according to PhysiciansPreference.com.
Other uses
L-carnitine supplements might have a positive effect on children with attention deficit hyperactivity disorder or ADHD, according to Bastyr Center for Natural Health. However, not enough scientific evidence exists to suggest that using L-carnitine can help people with ADHD. The use of L-carnitine should be discussed with a medical provider.
