Well it looks like the NIH is finally taking this vitamin D thing seriously. Harvard Medical School and Brigham and Woman’s Hospital are to enroll 20,000 people in a study taking vitamin D3 at 2,000 IU per day and fish oil for omega three fats. Twenty five percent of the people in the study are to be black. You can read the AP article here.
I believe the level of supplementation is less than half of where it should be, but this is enough to start to see the effect on chronic disease. The real issue is that it will take several years into the study to start to see that the nation as a whole should be supplementing. The question for you is that if it does no harm why wait until the study is complete to get your serum level high enough to where it will do some good.
The serum level should definitely be above 40 ng/ml of 25(OH)D and to get the best effect in the body it should be above 70 ng/ml. The NIH fact sheet (Table 1) says that harm does not start to occur until it is above 200 ng/ml and animal studies show that below 400 ng/ml is safe. This gives you a safety factor of at least 3 which is much better than most any prescription drug.
The thing that is really troubling to me is that many of the participants will be given placebos with no vitamin D. I will pray for these people that they do no die from this continued deficiency of this vital steroid. Hopefully as positive results are shown that the placebo group will also be given vitamin D.
If you decide not to wait because you already have one of the many chronic diseases from vitamin D deficiency then do what it says on the Vitamin D Council home page. The volume of research is already HUGE and why we need another study is beyond me. We have already done this the first part of the 20th Century when everyone was taking 2 tablespoons of cod liver oil, about 2600 IU of D3, per day without harm. The only issue was that the vitamin A level may have been too high in the cod liver oil. Look at the volume of research by disease at this Vitamin D Council Research Page.
I have been reading extensively on roles of vitamin A and how it interacts with vitamin D. How these two act in synergy is still not complete science, but I do feel much better when I eat liver or take about 4000 IU of vitamin A from fish liver oil. I will blog about this in the near future.
Here are the many diseases: 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.
Why wait!? It is your health and your life – be healthy! The encouraging thing about this pandemic is that the news of vitamin D is moving very fast through word of mouth and blogs like this one. We should start to see things like the overall rate of cancer start to reduce significantly as more people take it on themselves to supplement.
Go into the sun!!! The best time is between 11AM and 2PM when the UVB radiation is at it highest. Wear the least amount of clothes possible so that you do not get locked up and if you start to turn pink it is time to get out of the sun and wait until the next day. As you start to tan it will take longer and only about 15 to 20 minutes to start depending on skin color will be long enough. – Pandemic Survivor
