Well, it's worth using if you having any prostate issues (trouble peeing, feeling like you have to pee alot).
I use the 80mg Now Foods softgels when I feel like above- 2 pills 3 times a day for total of 480 mg - it makes me feel better within 2 days.
IMO, Good cheap supp when you need it. But I do see not much value in always taking it.
