I thought it was worth a shot; certainly nothing else had helped. My heavens! This has been the best winter, in terms of S.A.D., of my entire life!! No exaggeration.
Maybe this suggestion will help someone else, too.
I'm so glad you've gotten your SAD beaten! I know the B's are a big deal, and it's a bit complicated that D needs to go with K2 and also A and taken with dietary fat, but also calcium, magnesium, melatonin for some if having trouble sleeping but not more than 3mg, and now it seems iron (and vitamin C to help process it)
If I ever learned the iron connection I promptly forgot it because I have high iron in my well water, but when I go up north for the winter I'm eating fish so I should keep this in mind! I imagine a multivitamin would do the trick. I also learned the hard way that a few days of my son's zinc supplement put me in a better mood because I finally got rid of some sort of cold that I guessed was actually lung irritation from mold in heated forced air filters.
