Although hoodia diet pills that are 20x more effective sounds great, there are still many questions that surround this process. First, does the P57 active ingredient in the hoodia plant remain after the extraction process, there are many claims that hoodia extracts are much less effective than the pure hoodia. Secondly, hoodia from South Africa is very expensive, how is it possible for hoodia extract companies to use twenty times more product and sell it for such a low price? And lastly, are these companies in violation of Phytopharm's patent? Unfortunately we won't have any concrete answers until more research is done. As a buyer all you can do is try both types and see which works best for you.
