Well i'll be damn, look at good ol' ULTER on the diet board...
My main concern is with the strength comparisons between the two. We know that the R-ALA is 'assumably' a lot stronger and effective through studies. However, and I know FONZ and macro gave a guess of 35-40%, it is still debatable as to how much R-ALA is equivalent to a full strength racemic mixture. Once we get a better understanding of what this is, we can more accurately determine price advantages and disadvantages. Hopefully that made sense, and hopefully these percentages are even lower than the 2 given by FONZ and macro.
I will say that I commend AF for giving the public the chance to experiment and try the R-ALA. I predict the price is not all that bad either ($19.95/bottle) if it really is as strong as the studies claim it to be. I'll probably try it out and compare it in the future as I have been experimenting with this stuff for the last few years and have a pretty good sense of the racemic strengths.
The unhonosty of companies not putting the full ratio of the R & S-ALA is definately something that is up for grabs and a gamble as a consumer. This really blows, but I guess this is the case with all companies...you just never know 100%. The ones that stick around and continue selling certain products is a sign that it is a good buy, otherwise people wouldn't waste their money on crap.....ala HMB. BTW, i don't really question AF's quality, but as a consumer, we have to think this way. I'm sure the R-ALA will take off and be a great product, i'm as excited as anyone.
I just can't comment on the negating effects at this time as there just isn't enough info to really give an opinion on. Most people confuse the Biotin scenario though. ALA doesn't necessarily effect Biotin directly, but rather it competes for binding with biotin dependant enzymes in the liver that are responsible for creating oxaloacetate for gluconeogenesis and catalyzing leucine into acetoacetate and acetyl CoA. Therefore, there isn't really a biotin deficience per say, but rather a lowering of carboxylate enzymes available in the liver that bind with biotin.
For some reason, I don't think I needed to type this last paragraph...lol.
I wonder, and maybe MS, macro, cockdezl or anyone can correct me if i'm wrong, but if the S-ALA induces higher insulin levels, then this would actually help in lowering blood glucose levels furthermore. While the R-ala has a better GLUT-4 increase on the cell's surfaces, and therefore a higher percentage of glucose uptake, the insulin increased by the s-ala will assist in driving this glucose in synergistically?
btw...NICE SEEING YA!
