Thanks for your help, MrsD.

It is, indeed. But I don't have generalized allergies that are stumping me here, nor allergies to supplement ingredients, since I take the same ingredients in other supplements. It's either the source of the D3 or for some perverse reason to D3 itself, whatever that might mean.

But I appreciate your point. I'm going to let my body cool down for a few days, then I'll likely try rubbing in some of that softgel D3. Is that the one you use? I take it my skin can absorb that?

My body is reacting still. My histamine level must be high right now and the inflammation seems to have increased. I had breakfast today and the things I usually eat caused some itching and redness on the skin. I need to let my body cool down. I didn't have this reaction to the lanolin based D3, not even close. It must be lichen. I wonder if at the heart of my SFN and my health woes is some sort of bacterial, fungal, etc. infection. As soon as things cool down, I'll likely try what you suggest. I'll rub it into my hands or something like that. They have a 1000 IU capsule, so that might be better, smaller dose. Here's a question: if I rub int a 1000 IU capsule, do you think I'll absorb 1000 IU? Well, I suppose it's not too important. I also the Pure Encapsulations D3 (lanolin based), which has nothing but a cellulose capsule, so I might try that too. But I think what you suggest, bypassing the GI tract, and doing so with something that's very simple, is the best idea. Thank you.
