Well I guess when you go to a health care practitioner you're half expecting that you'll have to take some sort of product. So I don't see that there's anything wrong with them offering it to you.
Perhaps they were doing you a big favor. I have been taking those products since 2003 and they have saved my life. I mean I would probably be six foot under by now. Yes really, I'm not joking. When I was told about them I felt so bad that I said "I want some, and I want it NOW".
Yes it is a bit like Noni Juice only a lot better. Not all brands of Noni Juice are good either, some of them are heated in their processing and so the active ingredients have been reduced. There are some that are cold pressed and they would be OK.
And there's no way I'd take my supplements in to show my doctor. Unless they have done some study in the field of complementary medicine, they have no idea what they're talking about in that field. It's a bit like calling a plumber when you have an electrical problem in your house! They are not taught anything about nutrition or vitamins in their course, they are only taught about drugs.
Next time someone offers you something, go on the internet and study all you can find out about the science behind it. Don't take notice of a bunch of people who have never heard of it and don't have a clue what it's about. That's as bad as asking your doctor about natural stuff. Only take notice of people who have tried it, then if they say it's not good you know it probably isn't because they've tried it.
