Hi, Jerry.  My chiropractor suggested I take 5,000 mg. of D3 during the winter months and I have to say, I noticed an improvement in my mood.  I still take a smaller dose the rest of the year because I'm not much of an outdoors person and burn easily, but I know it's supposed to also help the absorption of calcium, which is an issue for me, as well.

Thanks for the info - sometimes simple things like this can make a big difference.  Lack of Vitamin B12 is another thing that can cause a lot of symptoms people don't know about, such as dizziness, weakness, etc.  As we get older, we tend to not metabolize it as well from our food and sometimes it's recommended that people get a monthly injection of it, which you can actually give to yourself. Anyway, a little off the subject, but it's another vitamin people should get checked for, too.

Hi Judy, Thanks for those insights and the additional information about vitamins. It seems this is one of those simple ideas that is within the grasp of pretty well everyone to try for themselves. What will be interesting is to discover the relationship between vitamins and moods and how they affect each other. Jerry
