Lipoic Acid

There's been a change in lipoic acid recently, a change toward more sites offering the R-fraction, known as R-lipoic acid. This is supposed to be better because it is used more efficaciously by the body than regular lipoic acid. Life Extension Foundation is adding the R-fraction of lipoic acid to many of their products, which is a sign that it's a good thing to switch to this more advanced form of lipoic acid. Is the old lipoic acid no good? No, certainly it's good. It's just that the new form is more easily used by cells and is therefore more effective.
