What Formula Ingredients Should I Avoid For My Newborn G6PD-deficient Son With Reflux Who Is Fussy And Vomits Often During Feeding?

Dear Doc, my son is g6pd deficient and has reflux. He is bottle-fed since Day 1. He is 1mo and 24 days old. What ingredient should I check on his formula to avoid complications? He had Similac One for a month and currently taking Bonna. He is always fussy during feeding and vomits a lot before we can even burp him. Thank you.
