It is attractive that α lipoic acid and acetyl L carnitine are taken at the same time. It is even better that it is acetyl L carnitine, not L carnitine! If it was greedy it would have been better if R lipoic acid was used. I do not have a change in weight yet, but when I commute by rowing a bicycle after drinking it, it gets hot in the middle and winter sweat although it is in winter, rowing with removing the button on my outer jacket. Is it good for those who do not sweat? Until before I used α lipoic acid and carnitine separately, I think that the amount of sweat has increased compared to that time. I do not complain if I lose weight! Maybe you should try people who do not sweat too much?
