I have had previous low serum level of vitamin D 19.5) after a deployment and was put on 50,000 IU pill to be taken weekly. I had no side effects from the pill and it brought my Vitamin D levels up to normal range after a few months.

I’m currently undergoing immunotherapy for stage IV metastatic melanoma in the lung. My vitamin D level was 39 before starting, it is now 9.5. (Unfortunately, Moffitt wasn’t monitoring my vit D levels and just assumed they’d be ok. It is not part of Moffitt’s protocol but it should be).

After having unexplained headaches, low grade fever, and fatigue, I went to my primary care physician and asked her to do a vitamin and mineral blood panel. I have been prescribed 50,000 IU pill to be taken weekly for 12 weeks. Many studies show low vit D negatively impact cancer treatments and survival rates. Just google vitamin D and cancer, as well as high dose vit D and cancer treatment, then select the scholarly papers.

I am a strong believer in vitamin D and have historically tried to maintain levels of 50. I have felt healthiest at this level.

I recommend taking it as your doctor has prescribed.
