Well finally saw my md today...as predicted LOW vitamin D levels (19)...als as predicted he wants me to start Vit. D supplements to help with symptoms. My concern is this....for the 1st time in 4+ years my sarcoid has been somewhat dormant. My lungs have been clear, I can take a deep breath and not start coughing. I have read that VitaminD can "aggravate" sarcoid....... Which do I learn to live with....sarcoid or symptoms of low Vitamin D.......any suggestions would be appreciated.
