i am very very much for using herbal/vitamin supplements to help with health issues. but i agree with dee somewhat. i've been trying out all kinds of things for years and have found with myself that i need to pay attention to the reactions i have when taking different things. a couple of things have disagreed with my body. i can't take red yeast rice for example. i'm not so doctor oriented, but i always make sure not to take anything over the recommended dosage on the bottle until i know i won't have an adverse reaction to that. and also it's good to use the internet to understand that some things can be very dangerous if taken in excess or with other things including food. melatonin has helped me sleep before but didn't work for a coworker of mine-so not everything works for everyone. a good website to get information is webmd. remember that not all websites are created by the experts and anyone can put things online. hth.
