Yeah, so have I, and I personally think (though I’m not an expert in this field) it's likely that the RDA is way too low. But there's a difference between the belief that RDA should be higher and the claim that the RDA has, in fact, been raised. It has not, it's still 600 IU/day.

  Doctors may be making those recommendations based on blood tests indicating specific patient deficiencies. As you note, though, research does at least suggest daily vitamin D supplementation in the thousands of IUs per day range may be considered safe. I'm not a doctor, but I believe if you've been directed by one to supplement vitamin D, blood tests probably should have preceded that recommendation.

  I've had one doctor prescribe me 10K a week. Another one recommended no more than 400/day. Doctors do not agree. Some have jumped on the bandwagon, and others believe it is just a bandwagon.

  I was told to take 20,000IU/day, just to be sure. It might be just correlation, but it helped with the issue I had.
