Avoid Vitamin D Deficiency at All Costs.

Vitamin Vitamin D3 deficiency is 100% in persons who are celiac or gluten sensitivity unless there is active ingestion of Vitamin D3 or active exposure to the vitamin D3 making sunlight- UV B light, which above the 49th parallel is only significant from late May to mid September.

 It is very important to keep your Vitamin D3 blood levels up because Vitamin D3 controls as many as 2000 of our 20,000 genes. ( Which are controlled by their on-off switches or epigenetic sites. Each gene may have as many as 100,000 epigenetic sites.The other major controller of epigenetic sites are the agents of methylation, like folate ).

Vitamin D3 deficiency is related to the onset of autoimmune diseases such as celiac disease, diabetes type 1, and many others. Deficiency is related to poor immune system and the inability to fight viruses and bacteria, like colds and flu's but also supplementing with Vitamin D aids in the cure of TB with anti-TB medications.

Deficiency is related to increased risk of cancer,depression, schizophrenia and other psychiatric conditions, neurological conditions and heart disease.

Slowly, administrative bureaus are recognizing the importance of getting more vitamin D3 both from food but also from supplements and sun. And recognizing it's safety in high doses up to 11,000 iu's a day (especially when combined with vitamin A and K). A great source of up to date information on Vitamin D3 is the newsfile Vitamin D Council.

Here they report on The European Food Safety Authority's recommendation to increase the their tolerable upper limit for Vitamin D to 4,000 iu's in adults and in teens above age 11.If put into policy and foods have more Vitamin D, and people will ingest more vitamin D, there will be less deficiency overall.

European Food Safety Authority ups vitamin D upper limit

14 August 2012

The European Panel on Dietetic Products, Nutrition and Allergies has recently increased their tolerable upper limit for vitamin D. Following a request from the European Commission, the panel took a look at research to date to re-evaluate if a change in the upper limit was necessary.

In result, the panel raised the upper limit to 4,000 IU of vitamin D/day for adults and teenagers older than eleven, despite finding no evidence of hypercalcemia or hypercalcuria in supplementation up to 11,000 IU/day. The panel cited that they did not want to raise the upper limit higher for the time being in order to take “into account uncertainties associated with these studies.”

Children between 1-10 years old, the panel proposed an upper limit of 2000 IU/day. For infants under one year old, the upper limit was set at 1,000 IU/day.

Their scientific opinion can be found in full in the European Food Safety Journal.

How does one know if one has a blood level of Vitamin D above 100 nmol/L?
You don't know unless you get a blood test. Ask for one or get one from the Vitamin D Council web page.

To your health!
