The heme iron in meat is absorbed better than the non-heme iron in iron supplements, but Impossible Burger has heme iron. It’s very frustrating that this biotech advance of in vitro heme production is so far only used for this specific brand of meat substitutes but that’s the situation. I’m not sure why iron supplements didn’t work for you, as that same paper shows that even non-heme iron is absorbed well when blood iron is low, but maybe it depends on the individual? In any case, and I promise the company isn’t paying me to say this, I recommend Impossible burgers to vegans. It has to be this specific brand, they have the patent. There was another company with a heme production patent but they recently shut down.
