Some interesting Vitamin D Deficiency causes are coming to light as increasing research reveals just how valuable Vitamin D is to our health.
But there are some questions arising too, as what level defines deficiency? Across the globe there are variances.
Vitamin D is not known internationally as "the sunshine vitamin" without reason.
The lack of sufficient exposure to the sun's UVB rays is more readily accepted globally now as research looks into so many ways the sun and Vitamin D are able to improve people's health issues, from relatively mild health disorders to serious life threatening ones.
Discovering whether you are Vit D deficient has therefore become a lot more serious in the medical world.
But it's not all as easy as that, as it is in fact quite complex, as there are so many possible causes.
Extracted from a reports by health organizations in the UK and the USA, I have chosen 10 interesting points I believe highlight vitamin D deficiency causes.
A statement was issued jointly by the following organizations in the UK on Vitamin D deficiency causes:
This substantial statement is remarkable in itself in that this collection of reputable health organizations has acknowledged the importance of stating publicly how vital Vitamin D is for human health.
The fact that they may be criticized by many for being too conservative is countered by the fact that there was comparative silence from their counterparts elsewhere in the world.
The following are 10 Vitamin D deficiency causes I found most interesting in this report:
Besides understanding the vitamin D deficiency causes, the level considered deficient or not is under debate.
The same UK based joint statement believes "there is currently no standard definition of an 'optimal' level of Vit D.
The consensus is that levels of 25(OH)D below 25 nmol/L indicate deficiency. Many have argued that this level is far too conservative", but there is new research challenging that this is OK for healthy people. It is those at risk of deficiency who may need more. Herein lies the conundrum.
Raising the levels of 'deficiency' or "sufficiency" depends on the outcome of research projects that will typically take time.
There is even a case reported whereby a 12-year-old girl called Tyler Attrill, diagnosed with the vitamin D deficiency disease Rickets, was told that her condition could have been caused by using an SPF 50 sunscreen for most of her life and depriving her of the essential vitamin and ultimately causing the bone disease.
See the BBC's video report about this: Sun cream caused vitamin D deficiency'
So, the bottom line is that sunlight exposure is good for you, it's free, and people should seek to expose themselves to the sun's UVB rays, without sunscreen, in order to produce more vitamin D completely naturally.
Just don't overdo it and get sun burnt!
There is an estimated 40% of people in the USA that are substantially vitamin D deficient, according to published research in July, 2018.
Deficiency is defined in the USA as having a serum vitamin D level, or blood level, below 20 ng/mL (ie. 50 nmol/L).
Just how statistics are obtained is always an interesting aspect to consider, but the following statistics for Vitamin D deficiency causes in the USA had some interesting results:
Harvard Medical School posted an article challenging whether 20 ng/mL is not too high to aim for being out of the deficient zone, where some people even go so far as to say 40 - 60 is the right level to aim for.
So 12,5 ng/mL is concluded to be more likely the correct level for healthy individuals. However, certain people at risk, need to work on getting to a higher level than 20 ng/mL.
People at risk include those with:
Likewise the following health conditions could actually be caused by a deficiency, so would help to boost Vitamin D levels beyond 20 ng/mL:
