My Integrative MD's know Dr. Berkson. I have asked them about R Lipoic vs the regular R and S that has been used many years, in IV, and in Europe. They always tell me to use the R and S.

I have had his book and I found videos last night. About 8 of them. My doctors told me why the Alpha Lipoic Acid I use is good, but in one of these videos he tells why he likes the reg. kind. If you do get R Lipoic, you have to watch where you get it and how the R and S are separated. You don't want it done with hydrocarbons.

He also said only capsules should be used with any Alpha Lipoic Acid. I haven't seen tablets, but cheap versions might have them. You have to be careful what you use.

His videos are wonderful. If I didn't have great doctors, I would see him. I hope we have him around for a LONG TIME! He has help patients that had no hope.
