Iron supplement recommendations (no big pills)

I’ve developed mild anemia at 19 weeks (pregnant with twins) and my OB is recommending 625 mg ferrous sulfate or elemental 65mg.

I don’t do well with big pills. Any recommendations for liquid, powder, or smaller pills/tablets (if that exists) that is gentle on the stomach and doesn’t cause nausea/constipation?

Also any vitamin c recommendations to go along with it?

Thanks in advance!
