Ulter and Macro,
I got in touch with Metagenics today. Briefly:
Q: The label states that your product is r-ALA is this correct? A: Yes
Q: Are you sure it is not just r heavy that it is in fact pure r? A: Yes
Now the chick i spoke to was just relaying my questions to their tech dept. so you may need something a little more solid than this. They aren't allow to send out info on their products so this is the best I can do from my end. Let me know if you find out anything.
