Do any of you have information about taking B-12 supplements? I am getting mixed opinions.

I hear mixed thoughts on B-12 as well. My own beliefs are that I should get enough from a good diet and my muli vitamin. Have heard of others getting shots and feeling energized, but I dont like needles and also think that should be a last option. Just my take on it, but others can maybe add their experiences. Good luck, and by the way what do you expect from the B12?

I have gotten very cautious about any vitamins or supplements. Here is a link to an article from the International Journal of Cancer (the Swedish study mentioned in your link)
In the abstract: "Increasing plasma levels of folate and vitamin B12 were statistically
significantly associated with increased prostate cancer risk"

After my surgery I met with my internist and among other things discussed vitamins. (His wife, also an M.D., specializes in diet and women's health.) As a result, I now only take a single fish oil capsule and 1,000 iu of vitamin D3. He takes one other supplement, an eye vitamin pill, because he has a family history of macular degeneration. He was not adamant about avoiding other vitamins, but he said that if you ate a reasonable diet, there was no medical support for additional augmentation.

I have decided that the risk-reward trade-off favors avoiding such things
Age at diagnosis 66, PSA 5.5
Biopsy 12/08 12 cores, 8 positive
Gleason 3+4=7
CAT scan, Bone scan 1/09 both negative.

Robotic surgery 03/03/09 Catheter Out 03/08/09
Pathology: Lymph nodes & Seminal vesicles negative
Margins positive, Capsular penetration extensive Gleason 4+3=7
6 weeks: 1 pad/day, 1 pad/night -- mostly dry at night.
10 weeks: no pad at night -- slight leakage day/1 pad.
3 mo. PSA 0.0 - now light pads
