Alpha Lipoic Acid: The Universal Antioxidant

Move over vitamins C and E, there is another antioxidant in town said to provide a far wider range of benefits. Lipoic acid, which is the priority name according to the American Society of Biological Chemistry, is also known as alpha-lipoic acid and thioctic acid. Like other antioxidants, lipoic acid has the ability to scavenge the body for disease-causing free radicals; however, that appears to only scratch the surface of this supplement's benefits...

Antioxidants typically come in two varieties: water soluble and fat soluble. A few, such as lipoic acid, are both. This dual nature allows lipoic acid to function in both fatty and aqueous regions of the body, an ability that is the reason…

 Alpha Lipoic Acid: The Universal Antioxidant

Scientific interest in lipoic acid shifted during the 1960s from its physiological role to its potential for therapeutic applications. After noticing lower serum levels of lipoic acid in individuals suffering from diabetes, liver cirrhosis and other diseases, a group of German physicians began administering lipoic acid to patients in order to help them overcome the deficiency. In doing so, the physicians found that orally administered lipoic acid is both well absorbed from the gastrointestinal tract and widely distributed throughout the body.

7 Incredible Benefits of Alpha Lipoic Acid

ALA is sometimes referred to as the universal antioxidant because it supports other antioxidants like vitamins C and E, and glutathione. ALA is involved in multiple antioxidant functions in virtually all body tissues, protecting your body’s organs and systems from damage so they can keep you fit and healthy.

Ask the Scientists

Alpha lipoic acid (ALA), also known as lipoic acid (LA) or thioctic acid, is a vitamin-like antioxidant. Some refer to ALA as the “universal antioxidant” because it has the unique attribute of being both fat and water-soluble.

Linus Pauling Institute

Lipoic acid (often called α-lipoic acid), also known as thioctic acid, is a naturally occurring compound that is also synthesized by humans.


ALA has recently gained a reputation as an antioxidant. In its reduced form, dihydrolipoate reacts and neutralizes ROS, such as superoxide radicals, singlet oxygen, and hydroxyl radicals. Thus, it is extremely beneficial in several oxidative-stress-associated conditions such as ischemia-reperfusion or radiation injury
