Alpha Lipoic Acid: The Universal Antioxidant for Brain and Cell Health

Small molecule, big role.

Quick answer

Alpha lipoic acid (ALA) is a natural compound made in small amounts by the body and found in foods such as spinach, broccoli, potatoes and organ meats. It is called a universal antioxidant because it works in both water- and fat-based parts of cells, regenerates other antioxidants such as vitamins C and E and glutathione, and helps mitochondria produce energy. Because the brain uses a lot of energy and is sensitive to oxidative stress, ALA is popular in brain health formulas. ALA may lower blood sugar, so people taking diabetes medication should talk to their doctor.

Key takeaways

Alpha lipoic acid is one of the most versatile antioxidants in the body. Here is why it matters for brain health.

What ALA does

Universal antioxidant

Most antioxidants work in either water or fat; ALA works in both, reaching more parts of the cell.

Antioxidant recycling

It helps regenerate vitamins C and E and glutathione, the body's master antioxidant.

Cellular energy

ALA is a cofactor for mitochondrial enzymes that turn food into energy.

ALA and the brain

The brain uses about 20% of the body's oxygen, which makes it particularly exposed to oxidative stress. ALA can cross the blood-brain barrier, and researchers have studied it for its antioxidant role in the nervous system. In Brain Savior, alpha lipoic acid is the main "protect" ingredient, working alongside phosphatidylserine, bacopa, ginkgo and Siberian ginseng.

Safety: ALA may lower blood sugar and could interact with diabetes medicines and thyroid medication. Talk to your doctor before use if you take medication, are pregnant or nursing.
