You could consider adding clams to your diet. Clams, oysters and mussels are all very high in iron, but clams have the most and, if I’m not mistaken, the best (though probably not conclusive) evidence that they don’t feel pain (you’ll want to read up on it and make your own decision as it’s been a long time since I read about it and I don’t remember many details).
I was rejected for blood donation because of low hemoglobin levels. I was worried about messing up the iron supplementation (too much is very bad apparently), so I ate tinned clams once or twice a week and the next time I was well over the minimum.
I should probably add that I’m not vegan and my mom also has low hemoglobin so it could be more of a hereditary thing for me. I also only did this once, but couldn’t manage to keep eating them very often after that and haven’t donated blood in a while. It’s something that would be pretty easy to try out though.
