Alpha-lipoic acid (ALA), known as Thioctic acid is a naturally occurring compound that functions as a powerful antioxidant in the body. It is produced in small amounts by de novo synthesis in the body using cysteine and fatty acids and can also be obtained through dietary sources such as organ meats, spinach, broccoli, and potatoes. while the human body produces small amounts of a-LA, obtaining it through dietary sources or supplements can significantly increase its availability.
