With over 30 years’ experience as a clinician and educator, Rachel translates emerging Vitamin D research into practical insights, helping practitioners navigate the evolving evidence. 

The discussion covers endogenous Vitamin D production through sun exposure, the limitations and interpretation challenges of vitamin D testing, dosing strategies including oral versus intramuscular approaches, and the role of supplementation in influencing clinical outcomes. 

Rachel challenges conventional assumptions, highlighting the importance of context, individual variability, and broader physiological factors such as inflammation, cholesterol status, and co-nutrient interactions.
