You may not want to order from Amazon (totally get it) but I’ve been happy with setting up their vegan D2 (yeast derived) on Subscribe and Save so that I don’t run out. It’s whatever the Amazon house brand is — https://smile.amazon.com/dp/B01L081FN6/

Vitamin D3 makes me literally insane with anxiety. I've tested it dozens of times, each time with the exact same insane anxiety effect.

So, recently I tried D2, and no apparent negative reaction. You seem to even react to that.

On amazon.com you can get plant based D2 made from yeast and D2 made from mushrooms.

Perhaps one or the other might work for your body chemistry.

And if neither, then just get outside in the sun.
