R-Alpha Lipoic Acid: The Natural Alpha Lipoic Acid
R-Alpha Lipoic Acid from Jarrow contains only the active R-form without the inactive S-form. This R-Alpha lipoic acid contains the stable Bio-Enhanced Na-RALA. R-Alfa lipoic acid is both water and fat soluble, making it highly absorbable. Our bodies make small amounts of alpha lipoic acid on their own, but its production decreases as we age.
Sodium R-Lipoate for Stability
Sodium R-Lipoate is the stabilized form of the body's natural R-alpha lipoic acid. Most products on the market are a mixture of synthetic (S-form) and nature-identical alpha lipoic acid (R-form). This is because of price and because R-alpha lipoic acid in its pure form is very unstable and temperature sensitive. That is a thing of the past with the sodium-R-lipoate compound. In addition, the health effects are almost exclusively due to the body's own R-form and one capsule now contains twice as much. In addition, sodium R-lipoate has a high bioavailability, so the same dose has more effect.
