Many ways to increase Vitamin D


Vitamin D levels around the world - 2014


Map of Vitamin D levels - 2001


400,000 IU loading dose: feel the benefits in < 7 days

Response with 400,000 IU loading dose @ is.gd/7DayVitD

Pre-term birth costs $51,800 (vs. very little vitamin D to prevent one: 10% of births are pre-term)


$10,000 higher VA hospital costs if have low Vitamin D

VA found less testing for vitamin D resulted in increased health costs – Jan 2012

Risk Factors for Vitamin D Deficiency


Many Vicious loops: low D ==> diseases ==> lower D
