  Note: It typically takes 5-15 years to see the results of Vitamin D Clinical Intervention Trials

1. Typically the intervention trials are for chronic diseases - which require a trial lasting 5-20 years

2. The publishing of results, including peer review, often takes an additional 3-5 years, as there is no funding by Big Pharma to publish quickly
