Yeah, i started taking 5000IU of vitamin d3 per day after reading the Henry Deacon post because i work in an office and do not always get 10-15 minutes of direct sunlight a day. It is hard to say if it has made me healthier because i rarely ever get sick. I have refused to take medicine since i was a young kid and i think it has resulted in me building up a pretty strong immune system. None the less, the vitam d3 advice resonated with me for some reason when i heard it, and will continue to take 5000IU a day.
