My iron levels crash when I'm pregnant. With my first they tried to get me to have iron infusions which I didn't want. I did a deep dive back then a found you can take all the iron you want but if your copper and magnesium (I think it was those two, might be wrong) are low you can't actually uptake the iron and use it. Too much iron sitting around unused in the body isn't good for a developing baby.

Instead I started having a teaspoon of black strap every evening and it fixed the problem in weeks. As he sort of mentioned it's full of all sorts of trace elements and minerals

I took it with my other two pregnancies and no iron issues. Also had way fewer pregnancy symptoms when taking it.
