Sorry I haven't been at the computer much today. I wrote down the supliments that Swimom recomended, and I can't find the list. Hopefully Swim will catch this post and help us out otherwise I will continue to search. I do recall one thing my wife brought home; Pomagranite Juice the flavor is rather unique, and needed to be mixed with OJ. After the first few months I went back to my normal Centrum Silver, and A Calcium supliment.
Found Swimom's List! B-12, B-50, Theralogix, C-500, Chromium-400, and Magnesium. I hope this will help. As with any meds or supliments you should first check with your doctor to make sure they will be ok for your husband to take prior to his procedure.
Good luck, to you both we'll be here for you.
