Yay! I got the right kind of calcium! My chickens get oyster shell, but they have gizzards. Even if I had a gizzard, don't know if I'd want to eat oyster shell - it smells like cat piss.

I can't increase my magnesium because it would have me in the bathroom too much. And when I first started taking D3 for SAD, I was taking (IIRC) 10k, but it was causing problems. I no longer remember what the problems were, but 2k has worked well for my seasonal depression. Any reason I should be increasing it to a higher but tolerable amount - say 4-5k?

I finally went to the local health food store & got iodine. It wasn't as pricey as I thought it would be. Hopefully it well help my poor thyroid.
