San, I'd make a guess that I bought my first bottle mid-fall last year. The label said take 3 caps, 3 times a day. I always err on the side of too little when I start a supplement, to see how my body reacts. I took that bottle taking 1 cap 3 times a day. When I ran out, I didn't go get another one, couldn't say it had done much (I'd eaten a cup of cilantro chutney one night as dinner and had detox symtoms for about a week after and I wasn't getting anything like that.)

I get NewTarget newsletter and ran across this:

and decided maybe I'd give it another try, got another bottle, took 4 a day and so on. Currently I'm taking 6 caps a day ... they're 420mg so that's about 2 1/2 grams a day? At this point, I keep thinking I'm gonna stop taking the stuff, I have LOUSY feeling days!!!! But then I realize I'm fighting to regain my health and I push on. I'm almost done with this bottle, the next one is in the house and I'll go to 7 caps a day.

I'll give you several other links, use them for the info, not for the products being sold!!:
