Tae Kyon Lee said:Bro, 400mg is a safe dose. I've run 600mg daily for two weeks and put up with the night sweats and discomfort and actually been disappointed with the results. As far as your question about liver toxicity goes, I wouldn't mind finding out about that myself (since I suffer from chronic hepatitis).
Probably something to look into before you start a new drug.
I have also seen recommendations like this:
Vitamin C (3000mg in divided doses) 2 times /day
Vitamin E (2000IU in divided doses) 2 times /day
Vitamin B (~500mg in divided doses) 2 times /day (2 caps of B-50 complex)
ALA (1000mg in divided doses) 2 times /day
