It's the time of year when the days are shorter and the sunlight becomes sparse. It's also the time of year when people become depressed and their vitamin D stores begin to deplete, coincidence?
A lack of vitamin D can be remidied by getting more sunlight, lying in a UV tanning bed or supplementing with some vitamin D. The latter of which is the easiest for some, especially if you work indoors all day.
Interestingly enough a new study has surfaced in which you can catch up on your vitamin D by taking it in one big monthly dose.
Similar results were had by those following these protocols:
1,500 International Units once daily
10,500 IU once weekly
45,000 IU every 28 days.
So basically for those that can't remember to take pills all that often, just have a system of taking it all in on the first of the month. How convenient! If you'd like to read further about the study you can find it here.
Lacking omega-3's and vitamin d? a pure source of cod liver oil kills two birds with one stone. Just don't take that all in a single monthly dose!
