Vitamin D: How Much Is Enough?

posted by hrossi | 3:59pm Monday February 8, 2010

vitaminD.jpgOne of the things that my integrative physician discovered when he ran a big battery of tests on me last fall was that I had a low vitamin D level in my blood.  This was not surprising–I’m a religious sunscreen wearer and most vitamin D comes from sun exposure.  Nor was it unusual–one study last year showed more than 3/4 of the American population walks around with a vitamin D deficiency.

Back in the fall, my level was 22 ng/mL, and my doctor wanted to see that at least double.  So I started a serious supplementation program – 50,000 IUs each week.  Vitamin D, unlike its water-soluble cousin vitamin C, is oil-soluble, so a weekly dose unfurls into your bloodstream nice and steady.  7,000 IUs a day is an optimal dose for someone trying to replenish their system, said my doc.

Eight weeks into this regimen, and my vitamin D level is up to 39–almost the doubling he was looking for.  Plus, I feel better – more “plugged in,” better able to concentrate, and more awake.

But now what?  What is the right “maintenance” dose to keep myself supplemented, but not overly-dosed?  My primary care doctor recommends 400 IUs a day for a year.  Dr. Andrew Weil–the famous integrative doc–has raised his healthy-person recommended dose from 1,000 IUs to 2,000 IUs a day. The Vitamin D Council advises 5,000 daily IUs while deficient, and then adjusting to whatever dose gets you to 50-80 ng/mL (which I’m not yet at).

All this from a vitamin for which there are very few food sources–milk, eggs, and oily fish basically sum it up.   

I’m sure I’m not the only one whose head is spinning–and given that vitamin D is crucial to the prevention of cancer, cardiovascular disease, diabetes, autoimmune disorders, and the common cold, the stakes are high to get this right.

Here are some tips from Dr. Weil:

1.  Take vitamin D supplements with fat-containing foods to help with absorption.
2.  Be extra D-vigilant if you are older–the ability to synthesize vitamin D declines with age.
3.  Don’t count on the sun: for half the year, latitudes north of Atlanta, GA are too steeply angled to give us vitamin D-worthy rays. 

How have you sorted out the vitamin D debacle?  How have you balanced diet, sun exposure, and supplementation to make sure you get this important vitamin into your system?

Don’t be surprised that you are vitamin D deficient because you use sun screen. I was reading in this blog:
http://justvitamind.blogspot.com/2010/02/vitamin-d-deficiency-in-australia.html
that even in Australia they are now seeing vitamin D deficiency in a wide percentage of the population. It seems there is this balance between skin cancer and vitamin D.

If you wish to see the latest research on supplementation vs 25(OH)D blood levels look at the graph at the top of the home page for grassrootshealth http://www.grassrootshealth.net/ . You will see that 2000IU a day is probably the minimum and 400IU a day will allow you to fall back to where you were. 6,000IU a day will raise 98% of the population to about the correct level and no one in their study came anywhere near the level where toxicity would start. There are no reported cases of toxicity with supplement levels below 10,000IU a day.

My obgyn told me that vitamin D3 is best (for women) and to take 2,000 per day….. I do not know what’s best for men and how much.
I agree with his advice.

I am the same way. I found out over a year ago that my vitamin D was low. I have been taking 50,000 to 70,000IU a week. I also have arthritis, since i have been taking vitamin D-3 I am not stiff or in a lot of pain. I also started gaining weight my doctor told me that having low vitamin D it can cause you to gain weight or have a hard time losing weight.
I feel so much better. I think this article is great. Hopefully this article will let people know how much important vitamin D plays a part of there lives. I tell people all the time what vitamin D has done for me.

In November my doctor checked my vitamen D level along with B12 and Folate because I was so tired and couldn’t seem to get enough sleep. The only thing low was my Vitamen D level. He didn’t tell me what the levels were. I took 1,000 IU daily for 2 months and he said my levels were ok but didn’t tell me how to maintain a good level. What is the safe and recommended daily dose? I am 49 year old pre-menopausal female.

Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight. It is essential for the immune and neuromuscular systems. Vitamin D-3 is the natural vitamin D. If it doesn’t say Vitamin D-3 than it’s probably Vitamin D-2 and is synthetic.
Vita Logic makes a good Vitamin D-3 1500 IU and is very cheap. 90 Tabs.
for $6.00.

As a strict vegetarian getting vitamin D3 is nearly impossible while living in Montana where the sunshine during the winter is to weak to be of benefit. My research thus far has not indicated any plant based D3 sources.

I heard that too much Vitamin D can cause kidney stones?
Has anyone else heard that? My brother’s Nephrologist told him that as he too is on Vitamin D.
We have kidney issues in our family so I don’t want any problems.
My Vitamin D is 23ng/ml. What is the normal numbers for this.
I am taking 1000 units a day and hope it’s enough.
Great article. Very informative as well but too would love to know how to maintain healthy V-D levels so I don’t take too much.

A few years ago I had a bone density test that showed osteopenia in a specific area of my back. I tried the drugs on the market now and they gave me extreem heartburn…I could not take them. My GYN said we would have to come up with something else but gave me no solution. That summer I read about vitamin D deficiency and started taking 1000iu of vitamin D every day. Little over a year later, with a new bone scan, my osteopenia was gone. All my numbers from the scan were better without any drugs and with just the vitamin D. I’m 58 years old now and have increased to 2000iu of vitamin D3. I don’t advocate everyone do it for bone loss, I just know what worked for me and I will always take it.

I too, like Tammy, have been taking 50,000 to 70,000 a week because my levels were still low (in teens and low twenties) after taking 2,000 a day for more than a year. Just had blood work taken last week, so I will let you know if my D levels are up! I have been feeling pretty great. Thing is–for folks on high levels of supplementation–you’ve got to go back and keep getting checked, just to make sure you’re not over doing it.

Several years ago my gynecologist did a bone scan which showed some slight bone loss in my right hip. she specifically told me to take Calcium Citrate; niot Calcium Carbonate as the Carbonate is almost impossible for your body to absorb. almost all these supplements come with vitamin D added to help in the absorption. Between that and other vitamin supplements I was already getting about 1200 IU daily of vitamin D, but about 6 months when my doctor did the every 3 month battery of blood tests that he does on me he found that I was very deficient in Vitamin D and had me increase my dosage to 2200 IU daily. I am very fair skinned, with blonde hair and blue eyes, so I never go out in the sun if I can help it and in the winter who is going to have much skin exposed anyway? I will find out with the blood tests next month if this is enough Vitamin D supplement or if I need more. Everyone needs to have those batteries if tests run at least once a year. It was through one of those routine batteries of tests many years ago that we found I had pernicious anemia ( B12 anemia) and I have to get a B12 shot regularly and I also have hypothyroid disease and take a supplement every day. Recent tests have shown that I needed to take more Thyroid hormone so my dose has been increased twice. It was also though routine testing that my doctor monitored my blood sugar, as Type 2 Diabetes in hereditary in my family. My doctor diagnosed me with Diabetes almost the day my blood sugar reached that level and I have been well-controlled on oral medication. blood tests are rather inexpensive and can give your doctor a world of information about your health!

I was diagnosed with Ostioprosis about ten years ago… as well as Avascular Necrosis… I have been on 1000 units of Vitamin D for years… but recently, my endo requested I take 50,000 units a week for eight weeks… followed up by the 1000 units daily …
won’t cure my ills, but can’t hurt either…just may discontinue future issues..

Anyone with bone density problems should also look into Xylitol!! It’s a natural sugar alcohol derived from Birch trees & other fruits & plants that has been shown to increase bone density (even in rats with no ovaries!) It’s also been shown to prevent cavities, gum disease, & sinus/ear infections when chewed in gum! I can’t understand why this isn’t in ALL our food!! I think it tastes just like sugar & eat it in my tea & on cereal. It also has 1/3 fewer calories than sugar & won’t affect your glycemic index so diabetics can eat it.

vitamin D consumption, according to NHANES data from 2005-2006 only 29% of adult men and 17% of adult women age 19 and older had intake of vitamin D from food alone that exceeded their Als. overall in the U.S. population, only about one third of individuals 1 years of age older had vitamin D intake from food exceeding their respective Als.

Vitamin D — the ‘sunshine vitamin’ is only part of the ‘miracle’ of sunlight.
Everyone knows the sun rises and sets every day and is the natural source of vitamin D — this cycle of ‘essential light’ also regulates brain chemistry and sets the basic rhythm of life.
check our site for additional vitamin D recommendations as well as a complimentary e-Book that i hope you find enlightening!
