@parkparker12890 There's a lot more nuance than that... But yes RDs are very valuable. You can still drink coffee, if quitting is too difficult, just wait for like two hours after your supplementation, but switching to other things can improve this.
@happywifehappylife As a doctor I don't believe this at all. Women can be vegan but iron levels often do need to be monitored and supplemented, and every physician I've worked with knows this as well.
Some studies say women absorb better if taking iron every other day rather than daily btw
