Calcium and Vitamin D Supplements

I was diagnosed with Gleason 9 prostate cancer in June 2013 and following this I had a robot assisted radical prostatectomy in July 2013. In September 2013 I was told that the post operative histology was T2, Gleason 4+3+5, margins negative but with a positive node. My PSA in September was 0.17 mcg/L but as this had increased to 0.38 by November, I was told that I was likely to have metastatic disease and had my first quarterly ZOLADEX implant later that month. Since then my PSA has been undetectable. I also had 33 sessions of radiotherapy in July and August 2014. In January 2015 a bone scan indicated that osteopenia was present in my spine and a weekly dose of 70 mg of ALENDRONIC ACID was prescribed. My GP has now prescribed Adcal- D3 a daily calcium and Vitamin D supplement. However I am reluctant to take this as I have read on a number of sites that these supplements should not be routinely recommended during bisphosphonate administration. I try to obtain an adequate daily intake of calcium and Vitamin D from natural sources such as nuts, oily fish, green vegetables and soya.

I would be grateful for ant advice about taking calcium and Vitamin D supplements in my situation.

Thank you for any assistance.


Re: Calcium and Vitamin D Supplements

Bisphosphonates are problematic. They impair the ability of bone to heal,especially with higher doses and therapy extending past 2 or 3 years. I personally would never take a bisphosphonate. Calcium supplements are associated with increased cardiovascular risk and are unnecessary for bone health if you have a reasonable diet.... and adequate vitamin D. Get your vitamin D level checked. Vitamin D 5000 IU per day is a reasonable place to start. Take vitamin K2 MK4, maybe 40 - 50 mg per day. Take Magnesium Malate about 1 gram per day. You can find this information with documentation on and

Thanks very much for the advice Jean Claude. I'll do more research on bisphosphonates before I see my oncologist again in two weeks time. I don't intend to take the supplements but to obtain adequate calcium and vitamin d from natural foods. I'll also get my calcium and vitamin d levels checked and look at the site you mentioned.
