Should I start my heme iron 14 days after I start the B12?

I would stick with the B12 for a month before you introduce anything else after that. So you want to give the B12 some time, you want to see how you react to it. So I would just give that some time before you introduce anything else. But then after a month, then I'd recommend introducing the heme iron supplement. If I've seen your testing and that's what I've recommended to you, then at that point, you would introduce it because ferritin can often drop when you first start with the B12. But it doesn't need to be exact. So these recommendations, it really depends on how you feel and how you're reacting to everything. But it is good to introduce one thing at a time. So you said, should I introduce the heme iron 14 days after the B12? You'd want to wait 2 to 4 weeks, then introduce it, and see how you react.
