do tanning beds help with the SAD / vit D issue? I really struggle with the blues and fatigue in the winter since I moved from FL to a northern state. It is not incapacitating, but unpleasant. Luckily I am able to go a a sunny place 1-2x a winter to recooperate.

Now I am requiring more calories (about 100 a day) to feel satisfied, and am slowly regaining weight, even though I am sticking to low carb. I take a vit d-3 suppliment. Would tanning beds used in moderation help?
