Clean nutrition shakes for weight gain

Hi all,

Sort of niche, but I'm looking for a clean nutrition shake that can help me gain some weight. I'm pregnant after multiple losses, in remission for Ulcerative Colitis, and have been underweight my whole life. I threw up my entire first trimester with my first daughter and she was perfect, but now that I have my UC diagnosis, it's really critical that I keep weight on as a risk is IUGR.

Anyway, I cannot seem to find a good brand for grab and go nutrition shakes like Ensure. Not just protein, but vitamins and minerals as well. I found one called Lucille for older people but not sure about it. Everything I've found has Natural Flavors and oils which i know aren't the end of the world, but the goal is to drink one of these almost every day (on top of real food ofc). I don't want to do a powder because I get so sick I simply need to grab a crispy cold drink from weeks 6-12.

Please help me in this bulking season! Thanks in advance
