Stabilized potassium salt of R-lipoic acid Factors distinguishing R lipoic (stabilized) from Regular R lipioc acid: - Stable at room temperature; does not require refrigeration
- Withstands heat up to 302F
- Negligible formation of polymeric chans of disulfides as a result of heat.
- Excellent dissolution and bioavailability
- Stable for 18 months as demonstrated by real-time and accelerated stability tests
- Developed using a patented low temperature, oxygen free anhydrous method
- Residual solvents and moisture removed through extensive processing
Description:
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. Furthermore, Pure Encapsulations R-Lipoic Acid (stabilized) delivers 100 mg of actual R-lipoic acid per capsule from 250 mg of potassium-R-lipoate salt. The natural R isomer of alpha-lipoic acid may provide enhanced antioxidant activity, energy production, and general metabolic function. 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 maintained healthy glucose metabolism and bile flow in the liver. Additional studies suggest that R-lipoic acid offers enhanced glucose metabolism properties in skeletal muscle. A University of California Berkeley study also 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.
Health Functions:
