L-Carnitine (specifically the L-isomer; D-Carnitine is biologically inactive and potentially harmful) is a conditionally essential amino acid-like compound: humans synthesize small amounts via the liver/kidneys (from lysine and methionine), but intake via diet/supplements is critical for certain populations.
Common commercial forms include L-Carnitine Tartrate (LCT) (high stability, ideal for supplements) and L-Carnitine Fumarate (LCF) (better solubility for liquid formulations). Its core physiological function is to transport long-chain fatty acids across the mitochondrial membrane, enabling β-oxidation (fat-to-ATP energy conversion); it also aids in clearing metabolic waste (e.g., lactic acid) from muscle cells.

• Endurance Sports (Marathon/Cycling): Added to pre-workout formulas to increase fat oxidation (reducing glycogen depletion) and extend exercise duration.
• Strength Training: Formulated in post-workout supplements to clear lactic acid (alleviating muscle soreness) and support rapid energy recovery.
• Body Recomposition: Paired with protein supplements for athletes aiming to preserve muscle while reducing body fat.

Weight Management

• Fat-Loss Supplements: Used in thermogenic formulas (paired with caffeine/green tea extract) to enhance fat burning during calorie-restricted diets.
• Meal Replacements: Added to low-calorie shakes to maintain energy levels while promoting fat metabolism.

Special Population Nutrition

• Premature Infants: Supplemented in infant formulas (per pediatric guidelines) to compensate for underdeveloped carnitine synthesis.
• Vegetarians/Vegans: Added to plant-based nutrition products (plant proteins, meal replacements) — since plant foods have low natural carnitine content.
• Elderly Adults: Formulated in senior nutritional products to boost cellular energy metabolism (alleviating age-related fatigue).

Medical Auxiliary (Under Professional Guidance)

• Non-Alcoholic Fatty Liver Disease (NAFLD): Auxiliary supplement to support hepatic fat transport (reducing fat accumulation in liver cells).
• Cardiovascular Health: Assists in lowering blood lipid levels (paired with lipid-lowering regimens) by promoting fatty acid breakdown.
• Chronic Fatigue Syndrome: Supports mitochondrial energy production to mitigate persistent fatigue (for eligible patients).

Pet Nutrition

• High-Performance Pet Foods: Added to dog/cat sports nutrition (e.g., working dogs, show pets) to enhance exercise endurance and metabolic health.
