Thought I'd give a quick update on my Vitamin D experience so far...
After reading this thread I decided to give Vitamin D a shot. While I was hoping for some improvement in Crohn's symptoms, my primary goal was to help with extreme fatigue and the lack of desire to do anything; the "nothing sounds fun" type of fatigue/depression combo that had become rather overwhelming. I also had pretty nasty "brain fog" that so many people with an auto immune disorder suffer from.
I started taking 6k I.U. of Vitamin D per day, along with Calcium and Magnesium on Feb. 6.
I didn't notice any change at all for the first week. Over the next few days, however, things started changing for the better.
As I write this, I am feeling better now than I have in years. Stuff sounds like it's fun and worth doing again, I have the energy to make it through the day, and (best of all) I'm Happy again. The "brain fog" has almost completely lifted as well. I even started Spring Cleaning without the wife's urging to do so (our bedroom carpet, walls, baseboards, doors, glass are all sparkling clean). I must admit, however, that starting on the garage Spring Cleaning is still a rather depressing thought.
While I feel *much* better overall, I have not noticed a decrease in Crohn's symptoms from Vit D, but that could also be due to the fact that I'm not taking it at a high enough level to have an effect on CD. I'm not going to increase the dosage anymore, though, until I have my GI check my levels at my next appointment in May.
While I can't (at least at this point) say that Vit D has helped my primary Crohn's symptoms, it has done wonders with the secondary symptoms (fatigue, depression, fatigue, brain fog, and fatigue) so many of us CD sufferers experience.
Edit: I think I should add that another possibility for Vit D not helping with my primary CD symptoms could also be due to the fact that I've only been taking it for 21 days so far. That's most likely not enough time to feel the full effects/benefit of Vitamin D supplementation yet.
If you're at the point where doing the smallest things sounds like way too much trouble, you should at least consider adding some Vitamin D to your life. Hopefully you'll have results like mine... or better!
To me, it's pretty shocking that just a simple vitamin could be responsible for such an amazing change. I never would have imagined that such a simple thing could do so much.
Huge thanks to everyone for the information shared in this thread. Thanks to you, I feel *so* much better.
Now if you'll excuse me, I'm gonna go get to work on that garage....
