Thanks for your reply Glentaj, i did check my blood glucose levels vigorously when i first started taking ALA and still do keep a constant eye on them, they have been very good, at fasting levels, before meals and 2 hours after meals.
Luckily i have had no stomach or any other possible side affects from this supplement, i did forget about the newer generation [ R] ALA which i will order next time when to need some more, thanks for reminding me.

Initially i got them because of the benefits that thioctic acid can have with helping to eliminate oxidative stress, whilst researching ALA i did come across literature commenting about possible energy increase but had no idea that it would be so profound.
I have only slight burning left on extremely hot days these days, so today and tomorrow will be a good test, as it's going to be really hot, today expected 106 F or 41 C in our measures and tommorow around the same.
