Description
"Carnitine" is an amino acid-derived compound synthesized from lysine and methionine, naturally occurring in meat, fish, and dairy products. Its primary role involves transporting fatty acids into mitochondria, where they undergo oxidation for energy production. Beyond this function, carnitine participates in enzymatic processes that regulate lipid metabolism and cellular energy balance. It further contributes to mitochondrial efficiency through biochemical exchanges. Widely distributed in animal-based foods, carnitine plays a fundamental role in metabolic function and physiological equilibrium.
Functions in the Body
Category
Deficiency Symptoms
Carnitine deficiency is rare but can be observed in individuals with genetic disorders affecting the body's ability to produce or absorb carnitine. Symptoms may include muscle weakness, fatigue, and heart problems.
Synergists & Antagonists
Carnitine is often combined with CoQ10, alpha-lipoic acid, and D-ribose for energy support and endurance. No known antagonistic effects exist.

Warnings
An overdose of carnitine may cause side effects such as nausea, vomiting, diarrhea, and an unusual body odor (a fishy smell). People with kidney issues or those prone to seizures should use carnitine cautiously and under medical supervision.
Food Sources
Carnitine is naturally found in foods such as meat, fish, poultry, milk, beans, and avocados.
Time Frame
Carnitine can be taken at any time, though some prefer it before physical activity to support energy metabolism.
Depleted By
Carnitine levels can be depleted by the use of anticonvulsants, sedatives, anti-cancer medications, antibiotics, and antivirals.
