Infant vitamins

Our pediatrician said our daughter (6 months) needs a liquid multivitamin with iron. She is breastfed and we’re just starting foods but she’s hardly eating any yet. We got the enfamil poly vi sol liquid supplement that was recommended but she HATES it. Rejects it every time. If any of it gets in her mouth she spits it right back out and gags. To be honest I don’t blame her, it looks and smells gross!! Any tips for how to get her to take this or suggestions for a better product?
