Magnesium and allithiamine started together four days ago. Plus I started the heme iron seven days ago. I feel like I've gone too fast and jumped the gun. I can't help feeling I've rushed into taking the heme iron. I've only been taking B12 for two weeks. Any suggestions? Do I need to stop taking the heme iron and wait until I've done a full month of the B12?

So you've definitely rushed. You need to introduce everything one at a time and you need to start with just the heme iron. And then you introduce that only after taking the B12 for at least two weeks, but preferably four weeks. So you've been taking the B12 for two weeks and you said you started the heme iron seven days ago, seven days ago after starting the B12. So just stick with the iron and then you should stop the magnesium and allithiamine. So you started those as well. So you're just going way too fast. You need to introduce those again later. So stop the magnesium, stop the B1, and just stick with the B12 and iron. And then when you introduce these supplements again later, you just want to introduce them one at a time. So give each of them some time. You want to monitor the effects of each one because otherwise you won't know what's causing what.
