Awhile back, I posted about emotional difficulties and fights with my adult child. Many of you gave me fantastic insight into this. Your posts increased my understanding of the emotional side of my daughter. I took her for a complete blood screening and they found her Vitamin D to be very low. The reading should be 30 to 100. It was 15. Now, she is on 1 per week tab of this vita at 50,000 iu for 12 weeks. It's been 4 weeks and there is a marked difference.
