Vitamin D

By Tanner | In Nutrition | on April 6, 2012

About 30 years ago… oddly about the same time as the food pyramid was released, the sun became demonized as the cause of skin cancers.  The knee jerk reaction was for the medical community to tell everyone to stay out of the sun or wear sunblock 1 million spf. Thirty years later and Americans get less sun exposure than ever and skin cancer rates have increased, not decreased.  Put the reduction of sun together with the new high carb, grain filled diet the FDA decided to promote and today you have the most unhealthy nation in our planet’s history.

While the links to the sun and skin cancers is debated heavily (even though people who live in the sun have less skin cancers than those who avoid it), the link to Vitamin D deficiencies and sun exposure are not.  Vitamin D, more specifically Vitamin D3 (Cholecalciferol), is synthesized in the body in response to the skin’s exposure to ultra-violet B rays of the sun.  It takes only minutes for you to synthesize 8,000-12,000iu of V-D3 when your body is fully exposed to excellent sun light.  Excellent sunlight?  Yes, mid day sun while living at or in near proximity to the equator.  If you don’t sunbathe almost naked three to five times a week for ten or fifteen minutes at your home in Equator or Congo, then you don’t get enough excellent sunlight.  If you sunbathe in North Carolina during the summers, then you are doing well for yourself…  but only during the summer.

Another little known fact about Vitaman D production is the trigger to activate it is in your eyes.  Wearing sunglasses stops the UV rays of the sun from indicating to the brain that you are in the sun.  This article, Malilumination, discusses the adverse effects of not getting enough natural light.  So even if you were sunbathing at the equator, if you are not foregoing the trendy glasses, you are not going to produce V-D.

So if you are not on your way to your tri-weekly sunning trip in Columbia, you need to supplement V-D3.  Most tout it as the most important deficiency to address…   worldwide.

Rightfully so.  Vitamin D is utilized in every metabolic function in your body.  Replenish your deficiency and you get better at every function that keeps you alive.  Vitamin D supports bone health, helps battle depression, improves brain function, and bolsters the immune system.  Heck, even Oprah’s website says Vitamin D is good for you.  And if Oprah says it, you know its real.  If you would like more info on all the diseases linked to V-D deficiencies, take a look around www.vitamindcouncil.org and take a read of the studies cited in this article by Coach Poliquin:

Vitamin D3: Best…Supplement…Ever!
The facts about one of the greatest discoveries in functional medicine.

Luckily, V-D3 is very easy to supplement.  A 5,000iu capsule is smaller than an aspirin.

The FDA’s recommended daily allowance for Vitamin D is 600iu a day.  That’s about enough to keep you alive.  The FDA’s RDAs are very low.  The RDA for vitamin D  is said to be sufficient to maintain bone health and normal calcium metabolism in healthy people.

Sufficient? Normal?  The problem with sufficient is it is not optimal.  And normal…  normal what?  Have you seen a normal American lately?!?!?  The last thing I want is to be as healthy (unhealthy!) as a normal American.  From thyroid levels to cholesterol levels, MDs use “normal” ranges to determine your health.  I don’t know of any better way than to sell yourself short in life than to just meet a normal level…  of any thing.  Basically, the RDA for Vitamin D is consider the amount needed to prevent Rickets.  Not sure what that is?  Yeah, because it’s not a disease anyone develops these days.  It is a painful bone disease typically found in extremely malnourished children.  Do you want your Vitamin D levels high enough to only prevent Rickets or high enough to thrive and be truly healthy?

This article, Higher Doses Reduce Risk of Common Health Concerns, Chris Meletis, ND further describes V-D disease links, but he also explains the RDA’s shortcomings well.  He cites giving his patients the RDA of Vitamin D3 does nothing to improve their levels of the nutrient.  To replenish V-D levels in his patients, he prescribes 8,000 iu a day.  That’s 56,000 iu per week and almost 100 times the RDA.

There’s a trick to Vitamin D3 supplementation.  For reasons still not known, V-D3 is restored more quickly by taking two or three large dosages per week.  So instead of a 8,000-10,000 a day, you would take 25,000iu-50,000 on Monday and Friday or on Monday, Thursday and Saturdays.

So how do you know how much to take?  Dosages are directly dependent on how deficient you are.  The “normal” in the US is 20-50 ng/ml.  That is low.  But again, normal in the US is sick compared to countries like Finland where the normal level of Vitamin D is 70 ng/ml.  The difference is standards.  Countries like Finland and Denmark have higher standards for measuring health.  They have lower rates of every disease compared to the US also.  It is also interesting that hormone and antibiotic fed meats are illegal in Finland.  Yes, illegal.  Yeah, Finland doesn’t have a huge agriculture industry to protect and subsidize.

To find out your Vitamin D levels, you can have your MD do the blood test to measure.  Most insurances cover it.  Another option is for lab work is Any Lab Test Now.  They are located in Land Fall Shopping center on Military Cut Off Rd.  You can walk in, get your labs done and have your results within a day or two.  Their tests are without  the doctor’s office mark ups, so they are very affordable if you need to pay out of pocket.

To better increase your Vitamin D3 supplement’s effectiveness, increase your intake of Vitamin E, Magnesium and Zinc.  V-E, Mg and Zn help facilitate the body’s uptake, storage, and usage of Vitamin D.
