Vitamin D Osteopenia, Osteoporosis research shows that this is an essential vitamin for anyone wanting to build strong bones. In fat studies place it 'center stage' in bone building.
Why? Vitamin D is the key to calcium absorption. If you do not have enough D, you can not build strong bones.
In fact when children have a deficiency it can lead to rickets. In adults, a deficiency in this vitamin, they can develop osteomalacia. This is a softening of the bones that often leads to misshapen bone, or bowed legs.
Vitamin D has three main forms and all three are important:
First, is the form as it is absorbed - either from our intestines or from our skin through ultraviolet rays in sunlight. Second is the form created in our liver from the first absorbed form. This second form is called 25 hydroxy-vitamin D5. Our bodies have more of this 2nd form than any other. The third form is the most important. It is made in our kidneys from the 2nd form:25 hydroxy-vitamin D.
This 3rd form is the active form and it is called calcitriol (1.25 dihydroxy-Vitamin D). This form helps in the absorption of calcium.
(Note the importance of our liver and kidneys in the transformation from the first into the third form. This Vitamin D use of liver and kidneys is the main reason why excess alcohol often leads poor bone building It is also the reason why kidney disease is often a precursor to Osteopenia or Osteoporosis. (See: Osteopenia, Osteoporosis Risk factors )
Calcium supplements are only helpful if there is enough stage 3 Vitamin D in the body to ensure that the calcium can be absorbed. This is important. Without Vitamin D, in particular Vitamin D3, you can not have strong bones. That is why Vitamin D Osteopenia, Osteoporosis is such an important topic.
You do not want to over do it and take too much of this vitamin.
Why? When you are in the process of converting stage 2 Vitamin D into the stage 3 form needed for bone building, it is your parathyroid hormone (PTH) that stimulates your kidneys to do the conversion.
If you have too much Vitamin D in your body, it can cause your body to release of too much parathyroid hormone (PTH).
AND because PTH stimulates osteoclasts - the cells that
dissolve bone, releasing too much PTH will lead to bone loss, not bone building. You do not
want too much PTH in your system - especially if you have Osteoporosis
or Osteopenia. It can sabotage your whole plan for Osteopenia treatments.Sounds complicated? Well in some sense it is. There needs to be a real balancing act. You need enough Vitamin D Osteopenia Osteoprosis ...but not too much or you will make things worse.
This is the reason I get a bit nervous when I see web sites and/or newsletters advising readers to take very high doses of this important vitamin without ever getting their Vitamin D levels tested. P
There is a simple blood test that will measure your Vitamin D levels - including the all important Vitamin D3. Why not ask your health care provider if s/he will order the test so you know 'exactly where you stand' on the Vitamin D Osteopenia Osteoporosis scale.
If your test shows below normal Vitamin D3, then you will want to consider a supplement and your health care provider ought to be able to suggest how much you should be taking each day.
Please, it is worth getting medical advice on this Vitamin D Osteopenia, Osteoporosis issue.
You do not want your levels to be too low because that is not good for bone building. BUT you also do not want to take so much that your Vitamin D levels are too high. Why? Very high levels can lead to a serious heart condition called atrial fibrillation. A blood test is not complicated and it can set you in the right Vitamin D Osteopenia, Osteoorosis direction.
