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.

for later
it cleans your whole body of anything nasty you might have picked up and might be hiding in your pores
why do ‘tabs’?? just eat jello
Why do either? My experienced validated the worthlessness of bothering with gelatin.
Just kidding about the Speedo. LOL
People need to be more aware of what they look like when they’re out exercising. Yesterday a gal on a bicycle passed as I waited for a red light. She had tights on but in the sun you could see right through the tights and see everything. It was not attractive or interesting. Now a Speedo, that is sometimes interesting.
very interesting thread
just because it didn’t work for you does not make it worthless
it worked for me, and many others have reported success with it
explain where else you can rebuild your cartilage?
I do sometimes 3 or 4 capsules of turmeric a day- since I don’t remember it every day
if you are taking a lot of vitamin D but seeing no effect, then add a bunch of Olive Oil and Fish Oil
It is a fat soluble vitamin
Don’t forget to take a lot of Olive Oil, Fish Oil and coconut oil if you are taking Vitamin D
it helps absorb it
:>).......already do....thanks.
D-3 is the key - I take up to 20,000IU - and have for years, particularly in this northern climate, in the months between mid-Sept - mid April.
There are two types of UV rays from the sun. One is beneficial- crucially so - one is not. (Take plants out of the light - and they will die. Sun is the life giver. )
Sad thing is, for years now, the 'advice' has been to stay out of the sun during the peak hours - which are the VERY hours we should be IN IT.
Use the old Biblical rule: "Moderation in all things." don't get a sunburn....
Do you perchance have any idea what the Vitamin D level is for people living ... ahem ... a "traditional tribal lifestyle" in Africa?
I stare into the sun for five minutes a day.
Mr. Mercat has had to be told a couple of times about his bike shorts. That’s my job. His best friend doesn’t seem to care. LOL Bikers!!
As long as it's from organic, preferably from grass fed (in sunshine) cows.
AND WHOLE!
Not GMO's, "anti-bioticed," "mastitis pussed", thin 'low-fat' pseudo milk.
On the farm - and until the low fat craze, (ie;, for thousands of years, we drank WHOLE milk.
The milk pails came up from the barn and were poured into milk separator...AFTER the household milk was saved out.
The separator 'separated' the cream out. That was stored in the cellar-way for a week for Friday's butter churning. The watery 'skim' milk left over was put in the swill bucket with table scraps for the pigs.
Get your VIt D the same way the cows get it - from the sun.
You may want to research the difference between magnesium oxide and magnesium chloride -
You didn’t actually read what I wrote, did you?
