Vitamin D: Could An Entire Industry Be Wrong?

How much do you know about vitamin D deficiency, really?

  • There's strong evidence against current practices in vitamin D testing, supplementation, and protocols.
  • Most practitioners are missing essential clinical considerations to comprehensively approach vitamin D.
  • There is a responsible, research-based, step-by-step strategy to address potential vitamin D deficiency.



There's a problem with how we're handling vitamin D in the functional medicine industry.

Actually, there are four big problems. 

Problem #1

Laboratory testing reliability

 Problem #2 

Reference range inconsistency

Problem #3

Supplementation variability

Problem #4

Protocol design mistakes

We're putting an end to this. After reviewing hundreds of research papers, we can confidently say there is a scientifically accurate way to approach vitamin D.

If this isn't a game-changer in the functional medicine paradigm, I don't know what else could be! The amount of time and effort put into this presentation must have been immense. I am honored to have been able to watch, learn, and grow into a better practitioner.
