First high-dose Vitamin D book by a patient who was also a doctor
The pain doctor had not known about the power of Vitamin D
Because of a serious accident, he became a patient
He discovered Vitamin D and greatly improved his health with high-dose vitamin D
He then went on to prescribe 30,000 IU of Vitamin D to >2,000 patients
His very well-written book includes many success stories with sleep problems, weight problems (both loss and gain), pain, and flu.
I have read and reviewed virtually every major vitamin D book written in the past decade.
This book is in the top 3 of more than 30 books.
