Carnitine deficiency occurs when the body lacks sufficient carnitine, a nutrient that is essential for the transport of long-chain fatty acids into the mitochondria for energy production. Carnitine is synthesized in the liver and kidneys and is also acquired from dietary sources, primarily red meat and dairy products. Deficiency can lead to a range of symptoms, including muscle weakness, hypoglycemia, and in severe cases, heart and liver dysfunction.
