Are you exhausted, tired, tense or unable to sleep through? Then it is likely that you have too little vitamin D. In this book, we consciously focus on vitamin D, how it is formed and needed, and what you can do if it is deficient. If you have little vitamin D, it is obvious to go to the sun from time to time after taking a short break from the office.

Do you want more quality of life? Then you are at right way...
