The best supp is Glucorell R because it combines the R+ ALA with Biotin. Since it's the lack of R+ Lipoic Acid in your mitochodria that makes your muscle cells insulin resistant there is nothing that you could supplement that would be any better. Glucorell R turns insulin resistance around in 15 minutes.
Glucorell R doesn't work with one type of carb. It works to replace the missing R lipoic in your muscle cells. Then whatever carbs you convert to glucose those muscle cells will be ready to uptake.
The evidence for CLA is not as strong. We actually stopped carrying it because we could get behind it.
NO! DO NOT BLOCK YOUR CARBS. This will do nothing for your insulin resistance problem and it's much better from a health standpoint to use them instead of blocking them.
if you are insulin resistant, go with at least 1 cap per meal (even if no carbs). though some people feel that they dont have to. (you should try it both ways... to get a feel for it)
general range of dosing is 1 cap per 25-50g of carbs (this is somewhat a bodywieght dependent dosage).
it is good to adjust your dosing up and down to see how you respond. Also the type of carbs is important to response (and this will vary individually).. ie you may need different OPTIMAL doses for 100g of oat carbs vs. 100g of dextrose.
you asked for optimal . but generally as stated above 1-2 caps per meal will provide solid results. if its a big meal 1-2 caps prior and 1 cap during works well for a lot of people.
