People stay away from acids if they can help it.
Yet some acids are very friendly. Ascorbic acid, lipoic acid and folic acid are three acids that provide great benefits to the human body. Ascorbic acid is, of course, vitamin C. Lipoic acid is also known as thioctic or alpha lipoic acid. Folic acid is sometimes referred to as folate. Antioxidants are such old news that people have drifted away from the research.
