uh.....26% have a deficiency. Another 31% have an insufficiency. The title says "most seniors have a deficiency". Who writes this stuff?

I don't find that number alarming. More responsible journalism would give Seniors suggesting on how to provide a boost to their Vitamin D intake.

Although often used interchangeably, vitamin D "insufficiency" and "deficiency" are defined differently. Vitamin D insufficiency is commonly defined as a [25(OH)D] level of less than 32 ng/mL; deficiency is defined as a 25(OH)D level of less than 20 ng/mL. Thus, patients who are vitamin D deficient are a subset of patients who are vitamin D insufficient.

The math seems to be correct. 25% + 36% = 61% = "most."
