Alpha Lipoic Acid (ALA), or lipoic acid, is a powerful antioxidant and a fat-soluble nutrient in the human body. Its primary role in cells is to participate in energy metabolism, which has antioxidant properties. Alpha Lipoic Acid can be obtained from food or taken in supplement form.
What is L-Carnitine?
L-carnitine is an amino acid compound that plays a vital role in the human body, mainly involved in the transport and metabolism of fatty acids. The adrenal glands and liver synthesize it, which can be obtained through food intake.
Source
Alpha Lipoic Acid:
Animal foods: α-lipoic acid is mainly found in animal foods, especially meat and internal organs. Animal foods such as beef, pork, lamb, poultry, and fish all contain a certain amount of α-lipoic acid.
Plant foods: Some plant foods also contain a small amount of α-lipoic acid, especially some green leafy vegetables and beans. Spinach, broccoli, carrots, tomatoes, peanuts, soybeans, etc., contain a certain amount of α-lipoic acid.
Food processing byproducts: α-lipoic acid is also found in some food processing byproducts, such as yeast and liver extracts. These extracts usually contain higher α-lipoic acid content.
Supplements: Besides food, α-lipoic acid can also be obtained as nutritional supplements. Many α-lipoic acid supplements are on the market, such as capsules, tablets, liquids, etc., which can be easily supplemented.
Carnitine:
Food sources:
Red meat: beef, lamb, pork, etc.
Poultry: chicken, turkey, etc.
Fish: deep-sea fish, sardines, salmon, etc.
Dairy products: cheese, milk, yogurt, etc.
Eggs: chicken eggs, duck eggs, etc.
Synthesis in the body: Besides food intake, the adrenal glands and liver can also synthesize L-carnitine in the human body. The synthesis process involves multiple enzymes and nutrients, such as the amino acids lysine and methionine, as well as vitamin C, B6, iron, etc.
Effect
Alpha Lipoic Acid:
Antioxidant effect: Alpha-lipoic acid is a powerful antioxidant that can scavenge free radicals in the body, reduce oxidative damage, and protect cells from oxidative stress. It can not only directly scavenge free radicals but also help regenerate other antioxidants such as vitamin C, E, and glutathione, enhancing their antioxidant effects.
Participate in energy metabolism: Alpha-lipoic acid participates in the energy metabolism process in the tricarboxylic acid cycle and mitochondrial respiratory chain in cells, helping to produce the energy required by cells. It can promote glucose metabolism and improve the efficiency of cell energy utilization.
Improve diabetes: Some studies have shown that alpha-lipoic acid can help lower blood sugar levels, improve insulin sensitivity, help control diabetes, and prevent complications. It can also reduce oxidative stress and inflammation caused by high blood sugar in diabetic patients.
Improve cardiovascular health: Alpha-lipoic acid can improve cardiovascular function, lower blood pressure, improve blood lipid levels, and help prevent cardiovascular disease. It can also increase the synthesis of vasodilator nitric oxide (NO) and improve vascular function.
Protects the nervous system: Alpha-lipoic acid protects the nervous system and can help improve nervous system function and reduce neuropathic pain and inflammation. It can increase the antioxidant capacity of nerve cells and reduce the occurrence of neurodegenerative diseases.
Improves skin health: Alpha-lipoic acid has anti-inflammatory and antioxidant effects, which can enhance the appearance and texture of the skin and reduce signs of skin aging. It can also help reduce skin inflammation and allergic reactions.
L-Carnitine:
Fatty acid metabolism: The primary role of L-carnitine in cells is to promote the transport of long-chain fatty acids into mitochondria, thereby participating in the oxidative metabolism of fatty acids and energy production. It combines long-chain fatty acids with coenzyme A to form acyl-CoA and transports them into mitochondria through transport proteins on the inner membrane for energy production.
Energy production: By participating in the oxidative metabolism of fatty acids, L-carnitine helps to increase the activity of the tricarboxylic acid cycle and electron transport chain in mitochondria, thereby increasing cells' energy production. This is essential for maintaining normal metabolism and cell function.
Sports performance: L-carnitine is widely used in sports nutrition and is believed to improve sports performance and delay muscle fatigue. By promoting the metabolism of fatty acids, L-carnitine helps to increase fat utilization as an energy source, thereby delaying glycogen consumption and improving exercise endurance.
Cardiovascular health: L-carnitine also has a specific protective effect on the heart and vascular system. It can promote the energy metabolism of myocardial cells, improve the contractility and relaxation function of the heart, and thus improve heart function. In addition, L-carnitine can also reduce blood lipid and cholesterol levels, which helps prevent the occurrence of cardiovascular diseases.
Antioxidant effect: L-carnitine also has a particular antioxidant effect, which can scavenge free radicals, reduce oxidative damage, and protect cells from oxidative stress.
