My hair dresser set out on a mission to lose 100 lbs. through diet and exercise at a gym under a personal trainer and she did it. She was advised to take a lot of vit d by her trainer. She started having headaches and a lot of joint, muscle and bone pain. She called her doctor and described to him what was going on and he tried several things and after weeks, he told her to stop the vit d and she did and immediatelhy felt better. I think that there is a fine line between enough and too much. Not sure where that is.
I have low vit d levels as measured by blood testing, and my pcp has me on high doses of vit D. I also make sure I get plenty of non burning sunshine exposure especially during the middle of the day when the UVB rays are most present.
Low vit D levels have been associated with cancers, nutrient absorption problems, bone issues, brain issues, and immunity.
I have taken oral vit D for one year and still have low level on year later, even in the summer. I have found that starting vit d with a lower dose and building up worked better for me, as the higher doses kick the immune system into too much, too fast and I didn’t feel well.
I think having good vit d levels is important for healing and well being.
