Vitamin D: Oral or Sublingual?


Vitamin D expert, Dr. Sarfraz Zaidi, MD recommends SUBLINGUAL route for the absorption of vitamin D supplement as compared to the oral ingestion. Why?

Because sublingual absorption takes vitamin D directly into the systemic circulation just like when vitamin D is naturally synthesized in the skin from exposure to sun.

In contrast vitamin D from the oral ingestion is absorbed into the portal circulation from the intestines, which takes it to liver first before entering into the systemic circulation. In this way oral ingestion is not very physiological and sublingual absorption is more physiological.

This point becomes even more important in people who have problems with digestion, such as people with pancreatitis, Crohn's disease, irritable bowel syndrome, gluten sensitivity, celiac disease, tropical sprue, and in people who take medications that can interfere with the intestinal absorption of vitamin D such as seizure medicines, cholestyramine, orlistat, and people with stomach bypass surgery including those with lap-band procedures
