I just had a complete physical. My tests were thankfully all good except for I was low on Vitamin D. I questioned that since I am outside all the time. The doctor explained since I am older, my body has problem using the sun's natural "D" and I need to take supplements.

Doing alittle research on low vitamin D I found out some interesting symptoms. If you have a severe deficiency, like me, some of the signs are:

*muscle pain without explanation
*depression
*chronic fatique

etc.

Also this was very interesting:

If you have constant pain in muscles and bones, for no obvious reason, you should visit your doctor and check your vitamin D levels in blood. This blood test does not take long, and it is quite sophisticated. If your vitamin D levels are lower than normal, you will be given vitamin D supplements to use. You will also be given some good advice on how to get vitamin D in the natural way (unless you live in a cold weather country, with not much sun).

Vitamin D deficiency symptoms can be very misleading. Take depression for example. Depression is one of the symptoms of long-term deficiency. However, this problem can be caused by many other factors. The causes of depression can be both physical and non-physical. To determine the causes, you will need to visit your doctor. It is always better to eliminate the physical causes first. Blood tests will be done in order to determine the nature of your condition. Some people have been treating depression with antidepressants that turned out to be completely useless. This means that the cause was physical, rather than mental. It is always recommended to visit your doctor, before you start taking any medications or remedies.

And very interesting....

Obesity can also be related to vitamin D deficiency. If you are trying to lose weight, but you are not getting anywhere with your diet – perhaps your vitamin D levels are low. According to several researches, vitamin D deficiency can prevent you from losing weight, no matter how hard you exercise. Patients who have recovered from vitamin D deficiency say that it is much easier to lose weight, now that their vitamin D levels are normal again.

Not that this is my excuse but it may be an explanation. I am picking up some supplements today to start taking.
