Clinical Summary

Persistent vitamin D deficiency is usually not a failure of oral therapy.

• adherence

• Vitamin D3 formulation

• administration with meals

• obesity-related pharmacokinetics

• malabsorption

• medication interactions

Most primary care clinicians should optimize oral therapy first and consider Endocrinology referral before IM vitamin D.
