Had a physical last week and coincidentally shortly thereafter I started feeling extremely tired. No other symptoms other than being tired from the moment I woke up until I went back to bed. Started taking vitamin D and along with a lot of rest I was feeling 100% better within a few days (I attribute this to a lot of rest rather than a few days of vitamin D). Got my results from blood work a day or so after I rebounded back to health and it turns out my Vitamin D was low. Never been a vitamin guy to speak of but I'm sticking with it now. 1000 UI per day as suggested on the bottle.
Anyone else in cold climates using vitamin D? Has it made a difference?
