I haven't heard of a correlation between mood and Vitamin D. BP is something different, as far as I know, and there's no "eliminating" it per se. All studies have indicated BP stays with us for life. We can only control it.

If you're taking lithium and Depakote (like me), there's probably something going on and increasing your Vitamin D might simply be an augmentation to your health. Eating well and staying healthy is a cornerstone of keeping BP at bay.
