I have been off hormones for almost 2 years with a rising PSA currently at 3.8. The doubling time approximates 10 months with no detectable PC identified by CT, fereheme MRI, and f-18 PET scans.
When first monitoring blood vitamin D levels from October through January, my levels actually dropped even though I was taking 5,000 IU per day. My blood level of vitamin D in January was actually 27 nmol/L and with a corresponding PSA increase of 0.5. Upon increasing my blood level of vitamin D to 47.6 nmol/L by February, the PSA concentration leveled off.
I know one month does not make a trend and PC is different within each individual, but I am hoping to keep this trend going. The goal for my blood vitamin D concentration is 60-80 nmol/L.
