Can i use buttermilk pancake mix? i have acid reflux. thanks?

It is said that because buttermilk contains lactic acid which neutralizes the acidity in acid reflux, it might be OK. But because it is a mix and other ingredients, used in preparing the pancake, might not be so harmless, it is best to stay with foods, One knows that One can tolerated without acid reflux. The Gastroenterologist is also there to guide One, if needed.
