I've tested very low (low 20s) in my vitamin D levels for over two years now. I have never tried to bring up the levels with high D-3 supplementation, but am going to now. I'm going to take 5,000-10,000 IU's a day for several months and see if I notice any difference in mood or tiredness. Already, after three weeks, I feel some decrease in fatigue, I think. I was wondering if anyone with long-term anxiety and/or depression had seen any benefit after taking D-3 supplements and raising their blood D levels. Appreciate any feedback with experiments. My B-12 is also consistently low, but B-12 shots and supplementation have little effect on my mood and fatigue.
