I take D3 5000 x 2 per day, citracal 250mg x 2 per day as my D strontium carbonate 340mg x 2 at night plus I for have excess urination in fact I feel I have become incontinente and I need to drink a lot of water. My blood test was over 200 the next time it was just 100 I thought that was high enough but my doctor said I should take more for the winter as no sun. I have not done much exercise lately and feel I would like to decrease these vitamins as I feel my kidneys and frequent urination is a problem and I am drinking much more water. could I have too much calcium in my blood regards cathy
