Determining the correct 25-hydroxy Vitamin D level is still a work in progress. In the 8 years I have been attending meetings, we have made considerable progress. NOF 2007 was the first time any society proposed an intake above 400 IU daily and a 25-hydroxy Vit D level of more than 20 ng/ml.
At the 2015 U. Wisconsin “Bare Bones Symposium” the latest recommendations were discussed. I have summarized them here.
Take Vitamin D3. D3 is Cholecalciferol (what we make in sunshine). Vitamin D2 is Ergocalciferol (what plants make and use). D3 works much better in people than D2 becuse it is the right stuff. It lasts 5 times longer and the assay is more accurate.
Test for 25-hydroxy Vitamin D level and aim for between 40 and 80 ng/ml. At 40 ng/ml over 98% of people can absorb and utilize Calcium fully. You want to have some margin of safety since lab test results vary by at least 20%. If you are seriously deficient, we give 50,000 IU of D3 every M, W, F based on your level and size, to correct the level quickly.
If you do not want to test your level, and you are the “average person” of 154# or 70 kg, you should take 3800 IU daily. This should achieve the 40 ng/ml level – eventually. If you are very deficient, this could take a year or more. If you are larger than the old average, or you have digestive issues, you will need more.
Finally, some cancer researchers believe that 70 ng/ml is better for preventing and treating cancers. If they are right, you should go for the higher level. If they are wrong, you have done no harm by going for the higher level.

Do better than another shirt or tie for Fathers’ Day. Make sure your Dad stays Fracture Free! What? Men don’t have Osteoporosis or Fractures. But they do!
25% of all Osteoporosis patients are Men. Each year 80,000 men have hip fractures. Over 30% of those men die of complications of their hip fractures.
1/4 of all Men over 50 will Break a Bone due to Poor Bone Health (Osteoporosis). More Men over 50 will Break a Bone than will have Prostate Cancer.
Many diseases and some medications increase fracture risk. So do many modern lifestyle errors. The good news is that simple measures can Decrease Fracture Risk.
Enough Absorbable Calcium spread out through the day. Enough Vitamin D3 to achieve a 25-hydroxy Vitamin D level of at least 40. 1 gram of Protein for every kilogram of body weight daily. Multiple Vitamins & Minerals. Balance and Weight-bearing exercises daily.

Recently a patient asked me to review all osteoporosis medications for her to consider and choose from. We had already optimized her Calcium intake, 25-hydroxy Vitamin D level, Protein intake, Multiple Vitamins & Minerals, and Exercise program. These had all helped substantially, but not enough for her peace of mind. She feels that she needs osteoporosis medication too. Here they are:
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?
