Well, speaking about lipoic acid,- it's quite natural, because this is basically what human body consists of. But you're right, not trusting the words of others. I don't trust anyone either. I'm telling you about lipoic acid from the perspective of my own experience. Perhaps, what is good for me, may be not good for you. OTOH, most of the time i'm taking Tioctacid (lipoic acid by MEDA), because i can't fall asleep,- not because my liver hurts.Thanks for the recommendation, Val. I do appreciate it. My problem is I’m afraid to take anything, even natural remedies. My daughter keeps telling me to try melatonin but my anxiety prohibits me from trying most things. It’s a problem, I know.
