I do think beta carotene (when not an excessive amount) can be helpful. I've found beta carotene containing things like orange juice helpful for improving my iron metabolism.
Unabsorbed iron can wreck havoc in our body.
For example 6 months into low Vit A with beef, chicken grains I felt like my gut was literally rotting from all the iron my breath smelt very toxic, I was very pale and sickly looking. It was when I added in beta carotene foods in while eating red meat all the colour came back in my face and I looked much healthier as I was now utilising iron better than before. So I think beta carotene can help improve iron metabolism and also be protective against iron too.
