Acid Reflux/Spit up

Amanda
Has anyone used this for their acid reflux baby? My son is almost 5 months old and had acid reflux and on medication for it but he still spits up a ton! Sometimes all of his bottle. We have tried a few formulas and I want to know if anyone has had good luck with this kind?! Please any advice will help or any suggestions on a different formula. He is using Gerber Soothe right now. Thank you so much!
