You are welcome.

I do not. Sheep get their Vit D from the sun like we do but they get it in their wool if I remember correctly (and I may not, but I think that is where lanolin comes from). I think that is at least one source of D3.

There are a lot of anti-animal consumption people out there that will shoot down anything that has to do with animal sourced products so just be aware of that possibility because sometimes they weigh heavy in the comments.
