My ID doctor told me he gives up to 9000 of IU of vitamin D3 to his patients without ill effects.Also,my oncologist is a great advocate of vitamin D3 for all his cancer patients.Being careful, I took a blood level test for vitamin D first and found out I was severely deficient. I started taking 600 IU of D3 daily and it did not help at all.So I started taking 500 IU increments with a blood test each 6 months untill two years later I finally reached a recommended blood level of 60-80 ng/ml. IT TAKES 2,600 IU of vitamin D3 DAILY in my case for me to maintain this safe blood level. I take it together with calcium for osteoporosis. I divide it into 4 to 6 smaller doses during my waking hours to prevent spiking of calcium blood levels which allegedly might increase the risk of heart attack. if taken at once or twice a day. It pays to do the internet research first on any medication or supplement you put in your mouth ..
Experts like Heaney consider the current recommendations are 200 international units for children and adults up to the age 50, 400 IUs for ages 50 to 70, and 600 IUs for those 70 and older. So anything above you age recommended dosage would be considered as to much!
