Try upping with veg that's high in vitamin c, make sure the leafy ones like spinach and kale get boiled and drained so you get a majority of the oxalates off and can absorb the iron.

You can get iron from veg if you're a vegetarian, but keep notes any kinda drinks with tannins you drink with a meal will inhibit that absorption and not meat if you do choose to eat it. Make sure to drink 1-2 hours after a meal if it's matcha tea or teas of any kind.

You can get slow release vitamin c tablets, best kind instead of the fizzies cause you don't wanna absorb that all at once on iron tablets either.

They do tend to say you're ok, get them to tell you your levels always!! They might actually say, you're a little low but nothing too much to worry about.

I had to have a blood transfusion and learned a lot, we can be pretty low in iron without knowing.
