That is a loaded question. It depends. What brought you to taking that amount of Vitamin D? According to the Office of Dietary Health under a health branch in the US, the recommended amounts for adults range from 200 iu a day for younger people to over 50 people 600iu. There are people that take 1000 iu and that is probably safe according to many doctors, but higher doses are more prone to problems without monitoring. This is a vitamin you can overdose on.

However, when a doctor finds you deficient and puts you on a higer dose that it ok as long as you are being monitored. This all also depends on what type D you are taking there is D2 and D3, the later is much more effective and absorbed more rapidly therefore it takes less.

I just read a report from an MD that 5000 IU is now becoming used more frequently. This is probably because so many people are very deficient in D. However, I would get the lab test first to see if, and how much, you are deficient.

I agree w/the previous poster in that D 3 is preferable. D2 is synthetic and can be toxic in large amounts. I take about 2000 IU a day. Of course this depends on where you live, but most people need more D in Winter.

Since finding out how vitamin D can prevent the flu, we are now taking 1,000 iu daily of D. And also 2,000 mg daily of vitamin C.

I don't understand why the CDC doesn't advise people to take these vitamins. All they tout is pharmaceutical stuff. It makes me wonder how knowledgable they actually are!

From what i have recently read on vitamin d 5000 IU per day seems to be way too much. We are currently taking 1000 IU per day, and i'm not so sure if that is also too much. We do live in Canada so right now the sun is scarce, but from what i've researched so far i have found that too much can do more harm than good.
I guess the best one to answer your question will be either your pharmacist or doctor,
but for now perhaps you should not takes really high doses as fact is they can be toxic and even fatal.
As for any vitamin currently being able to prevent us from getting the flu, there are no proven facts, for the present time it's wishful thinking, if only it were that simple.
