Ya that is a major problem up here for us dark dwellers... interesting thought.. cant hurt to increase it some... what harm can happen to those of us who are severly deficient anyway

They say most alaskans are very deficient in Vit d because of the lack of sunshine in this state.. even when there is sunshine we dont get enough for our bodies to manufacure sufficient quantities of vit d up here.
Dean---Sunshine, milk, cod liver oil... but you have to be careful it is one of the fat soluable vitamins.. it is one that your body will keep on board and you can become toxic with...ADEK are the 4 you have to be careful with. It isn like vit c that you get too much and pee out the rest.
