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.

Fractures are NOT FUN. Not something you want to repeat. Any fracture is a Bone Attack. It is a warning that you probably have Bone Health issues that can be improved. Get a Complete Bone Health Evaluation and work to prevent a second fracture. Most people can succeed in preventing that second fracture.
I see many individuals who have had a first fracture. Often the DXA, BMD, and T-score are not that bad. I even see many who have good DXA test scores. But they still fractured with relatively minor trauma. They proved that they have increased Fracture Risk. Why?
I was out at high noon (about 1:12 CDT) today, and may have made some Vitamin D in my exposed skin. We had beautifully clear skies with cool, dry air and lots of sunshine. I did not use sun-block for the few minutes of skin cancer risk. Unfortunately, it was also only a few minutes of Vitamin D opportunity.
Ultraviolet light is attenuated and eventually blocked by the atmosphere. The lower the sun is on the horizon, the less UV light gets through. In Waterloo, IA we are entering the 7 months of the year when the sun is too low on the horizon. We do not get enough UV to produce any Vitamin D.
Less than half of Iowans, who do not take substantial Vitamin D3 supplements, have sufficient Vitamin D levels in September. By early April, that is less than 15%.
A patient had no idea why her doc sent her to me for a Complete Bone Health Evaluation. As a “baby-boomer”, she lives by the motto: “You are only as old as you choose to be.” And she chooses to remain young. If only it were possible…..
“I can’t have Osteoporosis. I used to drink milk. I am active and I plan to stay active!!! So I just can’t have Osteoporosis!” Unfortunately, she does have Osteoporosis by BMD on her DXA, by the multiple Vertebral Fractures on VFA, and by FRAX. Still, there are simple steps to rescue her Bone Health before she Fractures.
