MSBS works great on my prostate problem
I have been taking one pill a day of Mega Strength Beta Sitosterol (MSBS) for two weeks. (The instructions recommend three pills a day with meals containing fat, but I have been taking only one with breakfast, whether or not that meal had any fat.) I am a 74-year old male of average size: 6 ft, 185 pounds.

Prior to starting MSBS I had to get up two or three times a night to urinate. Now I no longer have to get up at night to urinate.

Prior to starting MSBS I sat while urinating, because I could not pee straight. Now I can once again stand to urinate.

The reason I am taking only one pill a day is MSBS is intended primarily for maintaining a healthy cholesterol level, and my cholesterol level is fine. I think 375 mg of beta sitosterol per day is enough to take care of my prostate.

Works well. Much less need to urinate, especially at night. No upset to stomach at all. Good stuff.
