Your ‘EZ’ guide to optimal vitamin D intake

When you go outside into the sun on a cloudless day, will your skin start the process of synthesising vitamin D? If you live at the Earth’s equator, the answer is nearly always yes.

But that bright sunlight you see may or may not contain those crucial vitamin D wavelengths. The farther you are from the Equator, the more the Earth tilts away from the sun six months a year, putting more atmosphere above to screen out the vitamin D wavelengths. In Los Angeles on 1 January, for example, vitamin D rays reach the skin for only six daylight hours (approximately 9:00a.m. to 3:00p.m.). Even at the Equator, researchers have determined that clouds, aerosols, and thick ozone events reduce the duration of vitamin D synthesis considerably, and can suppress vitamin D synthesis completely. So even though it’s true that you could just take extra vitamin D, remember how I’m always telling you to ‘copy nature’?

The sun has more wavelengths than just the ones that deliver vitamin D. Just as you know it’s best for your health to take alpha-tocopherol with beta, delta, and gamma-tocopherols, it’s best to take calcium with magnesium, and it’s best to take the entire B-complex of vitamins together… it’s very likely best to take all the sun’s wavelengths on your skin together whenever you can in order to achieve maximum health benefits have health benefits too that just haven’t been ‘officially’ discovered yet.

Since you don’t live at the Equator, how do you know when those vitamin D wavelengths – along with other health-benefiting wavelengths – are reaching the ground in your area? As with many other questions to be researched in the 21st century, go online! All I had to do was go to the VitD-ez website, enter the date, location, and other details, and (after adjusting for the eight-hour difference between Seattle and London time (Greenwich mean time), I found out that those vitamin D rays would be available today (Monday 5 February) from 10:00a.m. to 3:00p.m. Seattle time).
