Vitamin D is vital in activating human defenses and low levels suffered by around half the world's population may mean their immune systems' killer T cells are poor at fighting infection, scientists said.

I did a blood test which confirmed my vitamin D was low, so I am taking 400 units a day now. My doctor said nearly everyone she is testing is low.

My levels are extremely low. I was tested in December and came in at 16.

Another thing I have noticed is I am sick alot this winter. I read something recently in a magazine that said low levels of Vitamin D and respiratory illness are linked.

Interesting article.

The general rule of thumb is that you need 1000 IU per 25 pounds to maintain current vitamin D levels. So to correct a deficiency you need much more. You also want to make sure you're using a D3 form to supplement. I took 9,000 IU per day and corrected a deficiency very quickly. The other issue is that anything below 50 is suboptimal and below 40 deficient. A number of doctors still call 20's normal which is sad for the people who are likely symptomatic at that level.

I hope you meant 4,000 iu a day. 400 iu will not raise your vitamin d levels to therapuetic if you are already deficient!!

Q - once you take the 9000/day and 'correct' deficiency levels, do you take less, or have to maintain that amount per day? Does the body store Vit D?

I was surprised that this was even considered "news" when I saw it this morning on CBS. I've been hearing about it for 2 years here. Of course Katie Couric had the "amazing" news a couple weeks ago that there were antibiotics and hormones in the meat supply. My DS was deficient and was on 3000iu/day for 2 months, then down to 2000iu/day. I'm on 5000iu/day. The rest of the family is on 1000iu/day. And we only use sunscreen in the summertime if we're going to be out all day on the water. There was a big article somewhere at the beginning of all the swine flu stuff about increasing Vitamin D to ward it off... maybe the Danish study was just confirming it?

you might want to research taking a much higher dose, 400iu is the minimum of doseing. i weigh about 140 and take 5000iu in the winter, living in a very grey, northern climate.
