I am not rid of cancer. There is no cure for metastatic prostate cancer; but I believe taking around 18,000 iu of Vitamin D is helping to keep it from progressing.
Are you sure your friend is taking 180,000 iu? That is a toxic level.
Sorry. I meant 18,000 iu daily. But there are some who take 50000 iu daily for a while. And good going on your cancer! You are taking an impressive amount of D3 daily! Take it with K2 and magnesium supplement such as mag glycinate.
Ultimate magnesium is the magnesium Threonate.
