BackDoc said:That's also my understanding that both R and S enantiomers of ALA in equal amounts constitute the racemic mix. I guess the racemic mix could possibly be a meso compound or other isomer, but I guess it does not matter. This is the limit of my understanding as I have long forgotten the advanced basics.
Interestingly, I have unknowingly preferred the R-enantiomer of ALA for weight loss (determined from the C of A from Jarrow) and I have not linked the structure's chirality with success with fat loss/muscle glucose effects. However, I have noted with some brands I need to take considerably higher doses to create the same effect. It seems to make sense about the R-enantiomer as one supporting data demonstrates (Am J Physiol 1997 Jul;273(1 Pt 1):E185-91). Here is the link to the study, as it may be of some interest:

I have not examined many brands of ALA to find out which are the R-enantiomers... I also must admit that I am not a very credible source for the range of therapeutic uses and ALA, so I would be no good except to see what I can dig up.
Good thoughts, thanks for the information -- it could very well be a quantity of ingestion issue. Luckily, there's S-type available cheap enough to take in large doses. I do believe that S-type is prevalent in the supplement industry (probably due to raw costs). Being a natural skeptic, manufacturer's certificates don't always mean it's so -- but in the absecence of tests, that (and results) is all one has to go on...
Maybe you could explain your dosing protocol for some of the guys that are interested in losing weight without going into ketosis? Also, aside from BMI tests, the scale and mirror, would there be any tests readily available and home administratable that one could take to tell if they're in a favorable glycemic state (outside of ketosis)?
