The Prosvent is a blend of some very good ingredients. I started this supplement about 2 weeks ago, a capsule in the morning and one in the evening. It really seemed to slow down my trips at night to the bathroom. But, the last few nights I have started those trips again though not as much. Before it was 3 to 4 times a night, then no trips, now back to one a night at most. It could be my life style too, consuming lots of water, soda, etc. late into the evening. I had taken saw palmetto supplements in the past and stopped because there was supposedly no clinical proof that it worked. A few years later it has been somewhat proved to work. Prosvent is different though, it has a mixture of other ingredients that enhance one another. Example, black pepper, which a lot of folks take with turmeric to help absorption. I still have half a bottle and I'm curious how this will go from here. Other than trips to the bathroom, this may help relieve other problems as well. It's all natural ingredient and said to have no harmful side effects. The pumpkin seed oil is good for parasites such as tape worms, etc. The vitamin D3 and zinc great for the immune system. Prosvent is expensive in a sense, but may be well worth it if it works for you.
