Would you say it's a big contributor to animal cruelty, or is it one of those byproduct things that don't mean much?
I would guess it's not very big. It's from lanolin, which is a coproduct of wool. I'm not clear on how much lanolin makes how much D3, but it's something like enough vitamin D3 to supplement a thousand people over a year with one sheep sheering.
Here's one site with some guesses:

@thebestofenergy this could be one of those things that would be good to add to the wiki. Maybe in the section on D and a page on animal products that cause marginal harm vs. benefit.

I would avoid it if viable, but otherwise don't worry about it if you can't afford it. It's not realistic to avoid it with formula.

I mean literally you have to add iron drops to the breast milk because milk doesn't contain adequate iron period. They're prescription drops, your doctor will prescribe them. Be very careful about dosing because too much iron can be very harmful. Read the label and directions meticulously.

Not too weird. Limiting iron is a good way to prevent bacterial contamination and sepsis.
The disadvantages of formula are few, and mostly involve people who don't have access to clean water to prepare it (which I assume is not you) or ability to wash bottles.
Breast milk advantages are immunological and mostly disappear after the first few weeks.
