Newswise — SAN DIEGO, CA (March 16, 2015) - Researchers at UC San Diego and Creighton University have challenged the intake of vitamin D recommended by the National Academy of Sciences (NAS) Institute of Medicine (IOM), stating that their Recommended Dietary Allowance (RDA) for vitamin D underestimates the need by a factor of ten.
In a letter1 published last week in the journal Nutrients the scientists confirmed a calculation error noted by other investigators, by using a data set from a different population. Dr. Cedric F. Garland, Dr.P.H., adjunct professor at UC San Diego’s Department of Family Medicine and Public Health said his group was able to confirm findings published by Dr. Paul Veugelers2 from the University of Alberta School of Public Health that were reported last October in the same journal.
“Both these studies suggest that the IOM underestimated the requirement substantially,” said Garland. “The error has broad implications for public health regarding disease prevention and achieving the stated goal of ensuring that the whole population has enough vitamin D to maintain bone health.”
The recommended intake of vitamin D specified by the IOM is 600 IU/day through age 70 years, and 800 IU/day for older ages. “Calculations by us and other researchers have shown that these doses are only about one-tenth those needed to cut incidence of diseases related to vitamin D deficiency,” Garland explained.
Robert Heaney, M.D., of Creighton University wrote: "We call for the NAS-IOM and all public health authorities concerned with transmitting accurate nutritional information to the public to designate, as the RDA, a value of approximately 7,000 IU/day from all sources.”
“This intake is well below the upper level intake specified by IOM as safe for teens and adults, 10,000 IU/day,” Garland said. Other authors were C. Baggerly and C. French, of GrassrootsHealth, a voluntary organization in San Diego CA, and E.D. Gorham, Ph.D., of UC San Diego.
About GrassrootsHealth:
GrassrootsHealth is a nonprofit public health research organization dedicated to moving public health messages regarding vitamin D from science into practice. GrassrootsHealth is currently running the D*action population intervention program to solve the vitamin D epidemic worldwide. Under the D*action umbrella, there are programs looking at the entire population as well as targeted programs for breast cancer prevention and a newly announced ‘Protect Our Children NOW!’ program to reduce the complications of vitamin D deficiency encountered during pregnancy and childhood.
Does anyone have any insight into this.
I have no insight, but this article inspired me to go pop a couple Vitamin D gummy vitamins. I also weight lift aggressively for bone health. And in the nice weather, I get a lot of sun, which is the best way to get D.
Also had a vitamin D test a week ago....so now I’ll definitely take care to see the results when they come in.
Bumped.
I take 5,000 IU of D-3 per day. A friend who is a Registered Dietician recommended this to me after I complained of hip pain after working out. All I know it that it worked! I take this on addition to my Omega 3 everyday.
drink a glass of milk per day
There is an easy way to know you are getting enough Vitamin D- you will start having more frequent and pleasant dreams.
No, I am not joking
is that another way of saying that the Vit D hormone is essential to proper sleep?
Fascinating. If you could elaborate, we’d be grateful.
My doctor asked me last week what my vitamin D3 intake was. I told hin 5,000 units per day (that is what walmart sales numbers know to be viable) He said that was ok
I started at 2,000 units years ago following a study posted here and had to take 2
each 1,000 unit gelcaps per day..... that was what walmart sold. They then began offering 2,000 unit gelcaps because that is what was selling. Just last year they began selling the 5,000 unit gelcaps and I reduced my intake from 6,000 to only 5,000.
At this level all respiratory congestion and drainage and morning hacking up stuff is gone. At < 5,000 units the drainage is present. I have no colds...... in say 5 years
Any way, walmart and now Sam’s where you can buy a years supply of 5,00 iu gelcaps for very cheap they reflect customer purchasing habits. Doctors are divided, but Walmart knows
And go for a walk. The sun doesn’t kill.
Drink your Ovaltine.........
I read a lot about vitamins- i started taking vitD supplements after reading something almost 20 years ago- and immediately noticed the connection between vitD and good dreams. I passed on what i had read and my personal experiences to others who have reported similar results.
I forget the original reading material that led me to try it, but I know it worked for me. Try it and report back if it works for you.
yes!!!!!!!!!!!!!!! The sun is GOOD FOR YOU = not a cancer-causing-killer. Just don’t overdo it
Ask your doc what he thinks about this......
How much do I have to drink for a Nicole Kidman dream?......
“...I take 5,000 IU of D-3 per day....”

Ditto. I started this after my annual physical several years ago revealed low vitamin D blood levels (that was the 1st year where my Internist began routinely including the Vit. D level test as part of the exam’s lab blood work. Upon retesting after several months my blood levels were up to where they should be.
Yeah I will.....just had a battery of preventative screening tests - from a mobile lab service - and once those results are in, my doc consult is the next step.
Ooh, me, rest? Don't have to tell me twice. I went home, threw a blanket on the grass and sunned my self. Figured it was my last chance before winter took over Michigan for the next few months. (and it was)
My vit D was down in the single digits and I was having all kinds of problems including substantial weight gain. Doc prescribed 50,000 IU / week. Did that for a couple of months and now I am taking 6,000 / day plus getting more sun.
I feel a whole lot better and was able to take off a good deal of weight.
Tell that to someone stranded in the middle of a desert heh.
You’re right though. Since I have been working outside more often, I am getting more vitamin D, I have been pretty healthy.
RE: I take 5,000 IU of D-3 per day. A friend who is a Registered Dietician recommended this to me after I complained of hip pain after working out.
It just so happens that that is my daily D3 intake as well.
So, did it do any good for your hip pain?
