Vegetarians and vegans are an expanding market. Some of them still miss eating meat, especially comfort foods like burgers. There is a good article that talks about the research done on the heme used in Impossible Burgers. It talks about the protein, how it's produced, and how it's digested. There was even research done to see how someone with a soy allergy would react to eating heme. Obviously, it's no match for a long term study and the article mentions that but from first glance, it appears to be safe. One thing the article mentions but doesn't expand on is what is in the other 20% of the extract from the heme production. https://newfoodeconomy.org/plant-blood-soy-leghemoglobin-impossible-burger/ https://newfoodeconomy.org/plant-blood-soy-leghemoglobin-imp...
