sunshine vitamin brightens dark winter days

As some of you may know I recently got my first smart phone. and on it there’s now a fun little app called D-Minder, intended to help track your vitamin D exposure. The app looks at your skin tone, size, location, local weather and sun angle to determine how much vitamin D you can get at any given time, or when your next vitamin “D opportunity” is.

Today, Nov. 15, the app says “your next D opportunity is in 113 days.”

All of this is a great reminder that at northerly latitudes like Portland’s, the sun’s angle is just too low for natural Vitamin D production for a big chunk of the winter. The D-Minder folks created this video, which gives the clearest explanation I’ve seen of how this works.

Why do you care? Vitamin D improves immunity and healthy bone building, protects against cancer and diabetes, regulates blood pressure and balances inflammation that’s thought to be a primary underlying cause of many debilitating chronic diseases. (Oregon State University’s Linus Pauling Institute offers this monograph on Vitamin D.)

What to do through the winter? If you can’t get a break to the tropics or the southern hemisphere,  recommend a simple lab test to assess your individual need and then appropriate use of a high-quality Vitamin D3 supplement.

(How much Vitamin D is enough? My reading of the research, coupled with clinical experience of myself, my colleagues and my mentors, suggests the U.S.-recommended daily values are too low.  But seriously, testing is the best way to know what’s right for you.)
