Vitamin D deficiency seems to be pandemic in the US, our RDA of 400 IU/day is pathetic. I have been testing myself and many of my patients routinely for vitamin D levels and I have been finding widespread deficiencies in my patient population and initially, with regards to my own vitamin D levels. I like to see 25-hydroxy vitamin D levels between 60-100 ng/dL and routinely see levels in the 20′s teens and even a few who had vitamin D levels that were “indeterminable” because they were so low.
Do you want to have your vitamin D levels checked? I can order this test and more at my Portland, OR, chiropractic, nutrition and functional medicine clinic, Optimum Function.
When low, I recommend vitamin D doses of 10,000-20,000 IU/day and when levels increase within my optimal range, I recommend a dose of 5000 IU/day. Generally, levels increase in 1-2 months using these doses. Don’t take my word for it! Come on in and let’s test your levels. For $59 I will have your vitamin D levels tested and give your my full report and recommendations.

Well, I certainly think so and I recommend vitamin D to most of my patients. How much? I usually recommend 1000-5000 IU/day; I personally take 5000 IU/day as I test my vitamin D regularly and I have been a little low for a year. Here’s an article dealing with this very topic: Vitamin D Deficiency Reveals an Instant Health Care Reform Solution.

A new review of the body of research on athletic performance and vitamin D suggests that adequate vitamin D levels in athletes could dramatically improve their performance.
Vitamin D is a steroid hormone that is activated in the kidneys; when activated, it regulates more than 1,000 genetic functions. This number seems to grow, touting the importance of vitamin D with every study published. If you have been reading my blog entries, you know that I have posted many blogs about vitamin D.
Researchers involved in this study reviewed the world’s literature for evidence that vitamin D affects physical and athletic performance. Numerous studies, particularly in the German literature in the 1950s, show vitamin D-producing UV light improves athletic performance. There is also a lot of research indicating physical and athletic performance varies in relation to vitamin D levels; it peaks when vitamin D levels peak, declines as levels decline.
What I found incredibly interesting is that Vitamin D also increases the size and number of fast twitch muscle fibers which could make an athlete more pwerful. It is apparent from this study and others that vitamin D levels are directly associated with musculoskeletal and therefore athletic performance.
The levels needed for these affects seem to be above 50ng/dl. As I wrote about in a previous blog levels may also protect the athlete from several acute and chronic medical conditions. Here’s a link to hat entry (Athletes Like The Rest of Us, Need More Vitamin D).

Surprisingly, a high prevalence of vitamin D insufficiency and deficiency has recently been reported worldwide. There has been recent evidence that this occurs even where sunlight is abundant. There have been theories that this is due to the changing atmosphere but no conlcusive evidence exists yet.
Very little is known about vitamin D status among athletes but a few studies suggest that poor vitamin D status exists among them. It is well recognized that vitamin D is necessary for optimal bone health, but many people don’t know that vitamin D deficiency increases the risk of autoimmune diseases and other chronic diseases and can also have a profound effect on human immunity, inflammation, and muscle function. It is likely that insufficient vitamin D levels can affect an athlete’s overall health and ability to train (i.e., by affecting bone health, immunity, and exercise-related pain and inflammation).
Although further research in this area is needed, it is important that athletes have their vitamin D status evaluated. I like to see 25-hydroxy vitamin D between 50 and 100 ng/ml but there is some evidence that it should be in the higher end of this range. I also recommend dietary supplementation with 2,000-4,000 IU vitamin D3 per day. Although this is significantly higher than what is currently considered the adequate intake, recent research demonstrates these levels to be safe and possibly necessary to maintain adequate 25 hydroxy vitamin D concentrations.
If you are interested in having your vitamin D checked, email info@OptFunction.com, The cost of the test is $50 plus an initial and follow-up visit. For the rest of 2009, I am running a special on vitamin D evaluation; $150 includes the initial visit, blood test and follow-up visit.

As many of my patients know, I am a big proponent of proper vitamin D levels. Vitamin D has been implicated in everything from bone health to cardiovascular disease to resistance to infection, to autoimmune disease to cancer. It’s an INCREDIBLY important vitamin; in fact it acts more like a hormone than a vitamin.
You can search through my blogs to see that I have presented some of the current research on vitamin D in previous entries.
Here is some exciting news. You can now receive an at home vitamin D test from that previously cost over $100 for $40. That’s cheaper than I can charge for a vitamin D test that requires a blood draw. Blood is involved with this test but it utilizes a blood-spot not a vial of blood. You prick your finger, put a few drops of blood on a card, let it dry and send it to the lab.
Is this procedure comparable to the whole blood test?
It seems to be!
What’s the catch? Well, GrassrootsHealth is doing a 5 year study on vitamin D so they need everyone to commit to 2 tests a year for 5 years. I recommend having everyone test their vitamin D levels twice a year anyway so this is very reasonable and clinically sound.
Here’s what you need to do to receive the test for $40:
- Logon to www.ordervitamindtest.org
- Fill in the health questionnaire
- Order your test kit–choose your subscription option; it’s a 5 year project and we need to have vitamin D measurements each 6 months for that period

A group of 18 scientists from the University of California recently recommended that daily intakes of vitamin D should be raised to 2,000 International Units (IU’s), . The “call to action” by the UC scientists, led by Anthony Norman, echoes a number of others including myself who have been recommending at least 2000 IU’s per day, and may increase the need for policy makers to review current guidelines for the vitamin. “Our consensus on vitamin D is intended to support public health action,” said Norman. “The amount of research that is currently available provides us enough information to release such a consensus at this time.”
If you’ve been keeping up with my blogs you will notice that I have written about vitamin D quite a bit. Living and treating patients here in the Pacific NW has determined that I make these recommendations for a higher daily vitamin D intake quite often. To get this level, it’s pretty easy and safe to do so using a Vitamin D supplement.

Anthony Norman, an international expert on vitamin D, in a paper published in the August issue of the American Journal of Clinical Nutrition, further enforced vitamin D’s potential for contributions to:
- Adequate immune system health
- The secretion and regulation of insulin by the pancreas
- The heart and blood pressure regulation
- Muscle strength and brain activity.
Access to adequate amounts of vitamin D (My recommendation: 1000-2000 i.u/day) is also believed to be beneficial towards reducing the risk of cancer.
Norman also lists 36 organ tissues in the body whose cells respond biologically to vitamin D, including bone marrow, breast, colon, intestine, kidney, lung, prostate, retina, skin, stomach and uterine tissues. Vitamin D acts hormonally in the body which sets it apart from the rest of the vitamins we know of.
According to Norman, deficiency of vitamin D can impact all 36 organs. Vitamin D deficiency is already associated with a reduction in muscle strength, a high risk for falls, and an increased risk for colorectal, prostate and breast and other major cancers.

Another study touting the benefits of proper vitamin D levels suggests a link between low levels of vitamin D and cardiac risk has been published. This study shows that vitamin-D deficiency is associated with both cardiovascular mortality and all-cause mortality.
The study was published in the June 23, 2008 issue of the Archives of Internal Medicine and conducted by a group led by Dr Harald Dobnig (Medical University of Graz, Austria).
The researchers note that an estimated 50% to 60% of people do not have satisfactory vitamin-D levels, and this is probably related to factors such as urbanization, demographic shifts, decreased outdoor activity, air pollution and global dimming, and decreases in the cutaneous production of vitamin D with age.
The minimum optimal serum level of 25-hydroxyvitamin D that I want to see in patients is 50 ng/mL, and levels lower than this are may bey related to compromised bone-mineral density, falls, and fractures and more recently levels lower than this have been linked to cancer and immune dysfunction, as well as cardiovascular disease, hypertension, and metabolic syndrome.
The researchers point out that recent studies have shown an association of low 25-hydroxyvitamin-D levels with important cardiovascular risk factors, supporting previous findings that demonstrated positive effects of vitamin D and its analogs on cardiovascular system health. “Together, these findings strongly suggest that 25-hydroxyvitamin D has beneficial effects, some involving the cardiovascular system, that are independent of calcium metabolism,” they comment.
