I am so sorry. My prayers are with you.
Seem to be doing OK, 4 years out now.
After my diagnosis, I started doing some serious research into what I was taking.
Calcium, seems to extend women’s lives but not men’s, maybe increasing my risk for CVD.
Multivit, no good evidence that it helps, some troubling indications it worsens your odds if you have been diagnosed with cancer.
Omega 3 supplement. No evidence it works and may be associated with prostate cancer.
and finally my Vit D. I had been taking it for about 6 years before I developed cancer, decided it wasn’t doing me much good. I do try to get out and hike in the sun so I’m not sure I ever needed it.
