you lost me right there. Show me the clinical data to correlate with what you are saying.Health Canada looks at vitamin D primarily for immune system functioning. The "average Canadian having acceptable vitamin D levels" is entirely arbitrary, just recommendations that fall in the CYA (Cover Your Ass) territory. Vitamin D as a mood stabilizing supplement is generally accepted amongst NDs everywhere and if you compare the vitamin D levels of Canadians to anyone near the equator, almost all Canadians would be considered deficient.

Get the drops, don't take pills, as mentioned you need calcium and fat to make pills bioavailable but taking the drops sub-lingually circumvents that.
It's such a cheap thing to try, has zero side effects and if it doesn't do anything for your mood at least you'll get one or two fewer colds this winter. On the flip side, it will be the best "anti depressant" you'll ever take.
