Potassium–R–lipoate is a highly bioavailable and stable potassium salt of R–lipoic acid. Regular R–lipoic acid is heat sensitive and may polymerize extensively, decreasing its absorption significantly. In fact, regular R–lipoic acid may need to be refrigerated and may only have a shelf life of six months.*

On the other hand, heating potassium–R–lipoate to 150°C (302°F) for 6 hours did not result in loss of activity and revealed less than 0.3% polymerization. In real-time stability tests, potassium–R–lipoate remained stable after 18 months. As an added assurance, Pure Encapsulations issued an independent accelerated stability test, in which potassium–R–lipoate was stable over a simulated 18 month period.*

In a recent in vitro study at the Buck Institute for Aging in California, R–lipoic acid moderated oxidative stress in neurons. A related study demonstrates the ability of R–lipoic acid to support memory tasks in animals by supporting mitochondrial function and protecting cells from free radicals.*

An animal study suggested that R–lipoic acid supported healthy glucose metabolism. Additional studies suggest that R-lipoic acid promotes glucose metabolism in skeletal muscle.*

A University of California Berkeley study indicates that R–lipoic acid may be protective against age–related oxidative stress in the liver. Furthermore, a study at Oregon State University established a potential role for R–lipoic acid in protecting the heart from age–related oxidative stress.*

What is the Source?
Pure Encapsulations R–Lipoic Acid (stabilized) delivers 100 mg of actual R–lipoic acid per capsule from 250 mg of synthetically derived potassium–R–lipoate salt. Potassium is from potassium carbonate. Calcium is from calcium silicate. Vitamin C (ascorbyl palmitate) is derived from corn dextrose fermentation and palm oil. Hypo-allergenic plant fiber is derived from pine cellulose.

CONTRAINDICATIONS:
People taking diabetes medications or medications for thyroid disease should be monitored by a health care professional.
