After a discussion with a prof emeritus at my university, who studied Vitamin D for over 25 years, I was reminded of the great importance of Vitamin D supplementation. If you didn't know, it regulates over 1000 genes!It is especially important for those of us up in the more northernly latitudes, where sun rays aren't strong enough during the winter months?
A good read is : Vitamin D, A Gene-Regulating Super Nutrient
How much should I take? He has taken 3000 IU's, but can only recommend 2000 IU's legally, because that is the current "established" Canadian limit, which he hopes to change in upcoming regulations. Also it is very cheap, so there's no financial reason not to supplement it.
So my question to all of you is, do you get enough Vit D?
Edit: Gah the >2k option got cut off, I will get it added, hold on if that's your vote.
