Vitamin D


Vitamin D is a fat-soluble vitamin in which many people are deficient in, especially those who live in northern latitudes or have difficulty absorbing nutrients. 

Vitamin D:

  • Turns genes on and off 
  • Affects various cells related to bone health 
  • Immune function 
  • Protection against cancer 

Recommended Daily Intake (RDI)

RDI may be a sufficient amount of Vitamin D level for maintenance if the level is already within an optimal range. Dosing may need to be increased for those that are Vitamin D deficient. It is nearly impossible to rely solely on consuming enough dietary Vitamin D to maintain optimal Vitamin D levels. Dietary consumption, safe sun exposure, and supplementation are key approaches for optimal Vitamin D.
