IMHO stick with the professionals and see it through.
That's the real advice right there.
In my father's case his doctor suggested both the Flowmax and the Super Prostate. I've just entered the stage of life where prostate health is a high priority concern, and I fully intend to follow whatever medical advice I get. I mention my minor supplement usage to my doctor (the only supplements I take have been doctor suggested), but if I had significant issues detected, or were exhibiting symptoms of serious issues, I'd be at least trying what the doctor suggests (to see how it goes).
My father still pees a fair bit but the Flowmax really did help him. I should have mentioned that in my original post. It was just the Flowmax, plus another medication, was dropping his BP too low. Eventually we were able to drop one of his BP meds to keep using the two medications in question. (My father needs a bucket of pills and supplements to keep going.)
Though you, or anyone you're acting as a caregiver for, should have their prescriptions and supplements reviewed on a regular (annual) basis. From experience people can accumulate prescriptions and supplements over the years. Think of it as a two pass process where you review things for yourself, or the person you're caring for, and then you talk to an actual professional (Doctor). Stuff does fall through the cracks (from experience).
When I started as caregiver for my father it took more than a little sorting out to figure out WTF was going on with his meds, supplements, and other things. My father would just say 'yes' to everything and keep refilling prescriptions / taking a thing, and bless her, but my mother never did stay in top of those things too well. So if you're acting as caregiver doing a review is a good idea (but I digress).
