Vitamin D Daily Dosage
I was told to either take 50,000 IU of Vitamin D once a week or 10,000 IU daily for a week. Which option is best? Should I split daily dosages?
Vit D: Take Vitamin D3. It is superior to D2. Take 5000 iu of D3 daily. 10000 iu is too much. Take 5000 iu daily for one week. Then drop to 2000 iu daily. ...Read more
Hi. I'm 19 boy. I wanna buy calcium vitamin D and I wanna know the maximum of daily dosage I can take.
Why do you feel: you need calcium? If you don't have lab tests to support this it's best not to take it. Just to answer your question, the US RDA for calcium is 1000 mg daily. Having co-factors like D3, K, etc. help it to go to your bones. I see that you have prostatitis and depression. The D3 can help w/depression and mood. Please see your doc for more guidance.

How long it will take my Vitamin D levels to raise from 19 to healthy level if I took 4000 Iu of Vitamin D daily? Is 4000 adequate dose to supplement?
My vitamin D was 10 ng/mL so my doctor recommended taking 2000 IU daily. How long should I take this dose?
Low vitamin D: requires supplementation of D3. Please do what your doc says but 2000 IUs is fairly low. Most of my patients take 5000 IUs daily. Your doc will probably re-test in a few months and you can ask him/her about the dose then. Peace and good health. ...Read more
