Just wanted to let everyone who's taking ALA know about a product I ran across today that seems pretty neat. It's called AOR R + SR Lipoic Acid. It's a sustained release version of lipoic acid, but it's in the "R" form or the more active form. It's supposed to last for 8-10 hours.
The best price I found was at BodyBuilding.com -- 90 caps for just under $30. I prefer to order from Amazon, but over there it was $45 for just 60 caps.
