River: The connection I needed?

[mdlbear]

Is this the causal link I was looking for to explain my mood shift?

It seems that coeliac disease is linked to vitamin D malabsorption (also calcium and vitamin B12, which I've been taking supplements for), which in turn is linked to SAD and depression.

OK, vitamin D supplements and no more gluten. We'll see if those work. Thanks to all the friends who helped me make the connection, especially dormouse_in_tea and mia_mcdavid.

I have recently read that the average American doesn't get enough vitamin D any more. We don't spend enough time out in the sun, for one thing. And, although all milk products are required to have supplemental vitamin D added, Americans don't drink nearly as much milk as they did when that regulation was enacted. They are now talking about increasing the RDA of vitamin D in multivitamins, and/or recommending that people take extra vitamin D. (Of course, you have to be careful about that, because vitamin D is one of the ones that are toxic if you get too much.)

Another data point is that it's been cold enough in the mornings for me to wear a long-sleeved shirt, so the amount of skin exposed to UV last week was considerably lower than it has been recently.

Except that the RDA is thought to be way too low, that skin production declines with age, and unless you happen to have a condition that interferes with vitamin D absorption.

*nod* my current dose as of a couple of days ago is 1200 IU: 400 from daily vitamins, and the rest from 400IU tablets taken morning and evening.

I've seen tablets up to 1000IU in Safeway.

I need to check what's in my multivitamin... I hate milk, except as an ingredient, and how much vitamin D would I get if I baked a cake containing 1 cup of milk and then ate a slice of cake? And I don't get very much sunshine - the Purple-Haired Fruitbat's habits are entirely nocturnal.
