dietary supplement, 100 caps./1 pack.
Swanson Acetyl L-Carnitine ALC dietary supplement is a high-quality product that is an easily digestible source of carnitine. It contains ALC (acetyl L-carnitine), the R-enantiomer of carnitine, and only this enantiomer has biological activity. This preparation is available in plant-based capsules, making it suitable for vegans and vegetarians. In humans, carnitine comes from two sources: it is synthesized and supplied in food. Foods rich in this amino acid include meat, primarily lamb, beef, pork, fish, and dairy products. The daily requirement for carnitine in a healthy adult is approximately 15 mg. In vegans and some vegetarians, the amount of carnitine in their diet is much lower, often insufficient to meet their needs. L-carnitine is an amino acid derivative widely known for its role in the transport of long-chain fatty acids into the mitochondrial matrix, where fatty acid oxidation occurs. Human muscle contains large amounts of carnitine, but this depends on its uptake from the bloodstream due to the muscle's inability to synthesize this amino acid. Mitochondrial fatty acid oxidation provides an important energy source for muscle metabolism, particularly during physical exercise. Randomized, controlled trials examining the effect of L-carnitine supplementation on obesity-related indicators have shown significant reductions in body weight, BMI, and fat mass. Interestingly, subgroup analysis revealed that L-carnitine demonstrated antiobesity effects only in overweight and obese individuals; weight and BMI reduction occurred in conjunction with other lifestyle modifications. In addition to its important role in lipid metabolism, L-carnitine is also a potent antioxidant, or free radical scavenger, which may protect tissues from oxidative damage. L-carnitine may contribute to reducing oxidative damage. Given its ability to readily cross the blood-brain barrier, supplementation with this compound may also be beneficial in preventing neurological damage resulting from free radicals. In summary, Swanson Acetyl L-Carnitine ALC is a high-quality dietary supplement that provides a valuable source of L-carnitine. This substance is easily absorbed and highly bioavailable. The advantage of the Swanson product is its safe composition and the use of plant-based capsules, making it suitable for vegans and vegetarians.
