Iron tablets - Black Poop

[OnNaturesCourse]

Has anyone experienced this?

I've been on 3 tablets a day for about 10 days now.

Will phone GP on Monday, just want to figure out if a call to 111 is needed?

Totally normal. You might prefer a gentler form of iron. There are lots of options, e.g. Floradix, Spatone, Solgar Gentle Iron, Viridian Liquid Iron. They just tend to be a bit more pricey unfortunately.
