There were several articles that came out about ayear ago that showed that over 80% of Americans are low in Vitamin D.
Vitamin D helps with bones, muscle, intenstinal function and yes, your feeling of well being....and it is because we have become a society of computer users, and indoor techno junkies....My Doctor said to take at least 1,000 units per day and to try for 10 to 15 minutes of sun....He put my mother on 50,000 units per week for three months, her level was so low...she was checked this week and her levels are now normal, so he reduced her dosage to 2000 per day. My doctor told me to tell all of my friends and relatives they need to take Vitamin D.
