Spring! Sunshine! Vitamin D?

Spring!  The Sun is back for more than 12 hours daily!  The sun crossed the equator at 0529 CDT.  Vitamin D?  Not so fast.  This is Iowa and we are still too far north.

Your skin can make Vitamin D when exposed to strong enough sunlight.  Strong enough sunlight happens when the sun is high enough in the sky that its UV rays are not blocked by the atmosphere.  This happens at mid-day all year round in the tropics.

Iowa needs to wait another couple of weeks for our first moments of Vitamin D from the sun.  Mid-day is around 1:10 to 1:25 pm CDT, depending on location.  Southern Iowa will get enough sunlight several days before northern Iowa.  Late June we will have 4-5 hours of opportunity.

Unfortunately, Vitamin D, Sunburn and Skin Cancer are often a package deal.  You can encourage them all, or block them all with Sun-block.

Your safest move is to protect yourself from sunburn and skin cancer, and take your vitamin D3 tablets or gel-caps.  A 25-hydroxy Vitamin D blood test will show if you have achieved the ideal range of 40-80 ng/ml.

You need to take control, but this is one area where naturally can have a significant downside.

Vitamin D is necessary in order to absorb Calcium from your diet.  Your skin can make some Vitamin D from the Mid-day Sun, but only in the “summer”.  The sun is high enough above the horizon at mid-day only 5 months of the year in Iowa.  Over half of Iowans are low on Vitamin D as summer ends in September.  7 out of 8 Iowans are low by mid April when we can first get a few minutes a day of Vitamin D.  That’s the Good News.

The Bad News is that Sun Block blocks Vitamin D production in skin.  You need to risk Sunburn and Skin Cancer “naturally” if you want to make your Vitamin D “naturally”.  Plus you need to expose enough skin (determined by your age and personal genetics) to make enough Vitamin D.

Foods naturally high in Vitamin D3 include “yummy” Seal Blubber and Cod Liver Oil.  Most Fish Oil does not have much D3.  Vitamin D2 from plants (like mushrooms) is much less long lasting than  D3, so we are talking pounds of mushrooms daily.

Your easiest and safest move is to take extra Vitamin D3.  The amount of D3 in your multiple vitamins and minerals, calcium supplements, and milk combined are very rarely enough.  Most of us need 2,000 to 5000 units of additional D3 daily.

Test for 25-hydroxy Vitamin D Level to tell if you are taking enough to get between 40 and 80 ng/ml in your blood.

Help to Take Control Naturally by getting enough Vitamin D.

Vitamin D From The Sun

Today we are just over 100 days away from the next Natural Vitamin D3 from the sun in Iowa.

Today, Sunday the 21st of December is the Winter Solstace of 2014 in North America.  The sun is the lowest on the horizon.  That means sunlight today has to travel through the greatest amount of earth’s atmosphere to get to us.

Today, the earth’s atmosphere completely protects us from Sunburn and Skin Cancer by blocking the sun’s UV rays.  This is good.

Today, the earth’s atmosphere completely protects us from Vitamin D3 by blocking the sun’s UV rays.  This is not so good.

Our next Natural Vitamin D opportunity will come at mid-day (a little after 1 PM in Waterloo, Iowa) in early April.  Until then you need to get your Vitamin D from foods or supplements.  Vitamin D3 tablets, capsules, gel caps or drops all can work.  So can tablespoons of Cod Liver Oil or several pounds of Mushrooms daily.

Test for your 25-hydroxy Vitamin D level to determine if you are getting enough.  Almost everyone is too low at 20 ng/ml and almost everyone has enough above 40 ng/ml.  I aim for between 40 and 80 for optimal bone health for myself and for my patients.

It is Winter.  Do you know where your Vitamin D is coming from?

Take Control of your health by finding out.
