Thanks for the info about biotin excretion, Scottyo, that was very important to me. I'mma up the biotin dosage dramaticaly now. Was taking 1.5 mg a day, going to 3mg.
I started another thread about a specific question about the nutrient partitioning properties of ALA but now I realize it should go here. Here I quote a post from the first page of this thread :

This is from Animals site:
Mechanisms via how you can manipulate nutrient partitioning....i.e. Insulin levels/Blood Glucose levels.
a)Non-insulin mediated glucose partitioning(Or if you prefer disposal). These types of supplements(For example R-ALA and Acetyl-L-Carnitine) work INDEPENDENT of insulin. They have little effect on its release or degradation in the bloodstream. What they do, is increase translocation of intra-cellular Glut-4’s(Glucose Transporters) to the outside of the cellular membrane albeit in the adipocytes(fat cells) and miocytes(muscle cells). The net result, is that more glucose is diverted to the miocytes, and less to the adipocytes. In hypocaloric diets, this means, more fat-loss, and better muscle preservation. In hypercaloric diets, this means more muscle gain, and less fat gain.
b) Insulin mediated glucose partitioning(or disposal). These types of supplements actually influence AA transport b/c they work through insulin signalling pathways. CLA is a good example. CLA works by increasing AA and glucose transport into the muscle cells via insulin stimulated pathways, and therefore in hypocaloric diets acts as an anti-catabolic. CLA also keeps blood glucose levels more stable. In essence preventing preventing high blood glucose or hypoglycaemia after a carb meal.
c)Non-stimulating thermogenics. GLA. In order to explain a bit how GLA works, I will briefly explain what prostaglandins are.

OK so this guy on "animal" board says that ALA sends more glucose to myocites (or all lean tissue?) than to Adipocytes. Great. I looked up "Alpha lipoic acid partitioning" on PubMed and found, well, ZIP.
So I just want to know the lowdown on this. Am I searching wrong? Does anyone have a research report on this? This guy's explanation doesn't seem very clear :
What they do, is increase translocation of intra-cellular Glut-4’s(Glucose Transporters) to the outside of the cellular membrane albeit in the adipocytes(fat cells) and miocytes(muscle cells). HUH? That literally means that this will send more glucose to the myocytes and adipocytes... But not to the other types of cells???
So anyways, whatever he MEANS, I think there is a lot of room for interpretation in there, so some science would really clarify things for me. Sorry if I seem picky, I just like to have all my angles checked.
Oh, and one other thing : I seem to be very insulin-sensitive (or very glucose-sensitive), meaning that taking too much carbs sends me into hypoglycemia easily. Well, just to experiment, yesterday I took 600mg ALA with a fairly low-carb meal (maybe 25g fructose) and sure enough, it WHACKED me down, nearly knocking me out for like 3 hours. Sheesh.
Cheers! And thanks.
