Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

My recent blood tests showed my Vitamin D level at 13. I am currently taking a D3 supplement (10,000 IU Sublingual) I really had no idea how horribly this was affecting me until I started reading the symptoms. My question is, approximately how long will it take for recovery? (Until I feel "normal" again)
