It's a good idea to be cautious. You can always run it by your doctor, since he would be familiar with your history and other medications. I passed it by my doctor and he said he was going to try it himself... lol

The Bee Pollen is the main Booster! I don't know how it all works together but it does. You can also check reviews on the product amazon's site, they are interesting reads also. Amazing stuff! It is a good idea to take mini breaks when using it, I take it for 10 days and then take 5 days off and then go back on it. When you first begin taking it you do not see any real effect until at least 2 weeks in and you should take it for at least 4 weeks the first time you try it without the break, you will know if it works for you by the 4th week. Taking the break gives your body a chance to rest and with herbs they recommend it so they keep working at optimum levels. I counted it a blessing when I read about this stuff years ago on a trip back from Europe and it was in the plane's back seat pocket. I have been using it for years even before it was available in the US so easily as it is today.
