In my practice over 80% of patients whose vitamin D levels I check are deficient.
If your blood level is less than 35 ng/ml, I recommend you correct it with 10,000 of vitamin D3 a day under a doctor’s supervision and then recheck your blood levels after 3 months.
It takes a good 6 months usually to optimize your vitamin D levels if you’re deficient.
Once this occurs, you can lower the dose to the maintenance dose of 2,000 – 4,000 IU a day.
It is estimated that anywhere from 30 to 100% of Americans, depending upon their age and community living environments, are deficient in Vitamin D.
More than half of all American children are vitamin deficient.
Supposedly almost 3/4s of pregnant women are vitamin D deficient, predisposing their unborn children to all sorts of problems.Worldwide, it is estimated that the epidemic of vitamin D deficiency affects one billion people.What I and many of my colleagues around the country are finding is that even people spending what we thought was adequate amount of time in the sun, are still showing up with low blood vitamin D levels.I am not sure why at this stage but there is an easy and cheap solution…vitamin D supplementation.Here are some guidelines: If your blood level is above 45ng/ml and for maintenance, I recommend 2,000-4,000 IU daily depending on age, weight, season, how much time is spent outdoors, where one lives, skin color and obviously blood levels.In other words if you are older, larger, living in the northern latitudes during the winter, are not getting sun and have dark skin, I recommend the higher maintenance dose.
