What is Doctor’s Best Stabilized R-Lipoic-Acid?
Alpha-lipoic acid is a sulfur-containing fatty acid that performs vitamin-like roles in the body but since the body produces lipoic-acid on its own, it is not classified as a true vitamin. It functions as a co-enzyme in the metabolism of carbohydrates and is required for synthesis of acetyl CoA, a key metabolite in the cellular process that turns glucose (blood sugar) into energy. Stabilized R-Lipoic Acid contains Na-RLA, the sodium salt of R-Lipoic acid. Pure R-Lipoic acid is a very unstable molecule that has a tendency to polymerize with exposure to heat, light, and moisture. Na-RLA is a stabilized form of R-Lipoic acid that won’t degrade at high temperatures.

How does it work?
Lipoic acid is a key factor in the cellular process that metabolizes glucose for energy production. Aging is accompanied by a decreased ability of the liver to recycle ascorbic acid following oxidative stress. R-lipoic acid, has been shown after two weeks of supplementation to aged rats, to reverse the age-related impairment of ascorbic acid recycling and concentration in liver cells. Aging is also associated with oxidative stress in the brain. The brain’s high rate of metabolism and its long-lived neurons make it particularly vulnerable to oxidative stress. Since lipoic-acid interrupts cellular oxidative processes in both its oxidized and reduced forms, it plays a modulatory role in the brain and nervous system.
