I have been taking this kind

for about 9 months and I love it! I have had problems receiving it, however and when I have contacted them they say that sometimes it is hard to get and the orders get backlogged. That said, I have never NOT gotten an order, sometimes it has been delayed. The last 2 orders came within 5 days. It says to take 2 pills before every meal, but I find I can get by with using it once or twice a day so it lasts longer which is good because it is $$. I have tried a couple of other ones (including the ones you guys have linked to), but this is the best. Good luck!
