I have been taking these tablets for over a year now. I read somewhere that ALA was good for neuropathy along with Methyl B-12 which I also take. The ALA always lowers my blood sugar and balances it out because of the timed released tablets. But the big bonus is how my skin began to look and how my hair, that was thining, began to grow. I haven't had a pony tail since my teenage years but now I have a real one.
