Hi Heather @heathert, the research on iron supplementation and mycobacterial growth has been contradictory. More of the research has been done in Africa with populations regularly having high iron loads in their diets, and even overloading of dietary iron on a frequent basis. in those studies, people tended to have poorer outcomes with mycobacterial infections.
Some other studies have found conflicting results -- iron supplementation even during TB had no effect on the mycobacterial burden in the lungs.
However, recent research with other populations found that if you routinely have low levels of iron in your diet, and have had some degree of anemia -- for example many vegetarians -- then supplementation with iron has no effect on increasing mycobacterial growth.
So if you continue to be a vegetarian, you should be safe to take iron supplements.

@heathert ...Thanks for the heads up on the iron. I will be asking for iron bloodwork next I visit my GP, since I am vegan too I did see this (not sure where) and thought it important.
"Iron is a double-edged sword. If we don’t absorb enough, we risk anemia; but if absorb too much, we may increase our risk of cancer, heart disease, and a number of inflammatory conditions. Because the human body has no mechanism to rid itself of excess iron, one should choose plant-based (non-heme) sources, over which our body has some control."
