When I was at the F & F Center last week meeting with the doctor regarding my blood work, he mentioned that I have a serious Vitamin D deficiency that needed to be treated ASAP. I was surprised when I found out what all Vitamin D deficiency causes. Vitamin D can be obtained through foods and sunlight.
The doctor said that Vitamin D deficiency can cause extreme fatigue, muscle and joint pain and it can lead to serious illnesses such as cancer, MS, rheumatoid arthritis and autoimmune diseases.
The doctor put me on a very high supplmentation of a product the F & F Center produces called Bone Health that I am to take twice a day. Hopefully this will increase my levels.
Here is a site that discusses Vitamin D Deficiency from the Vitamin D Council.
