Why can I add protein powder or nut butter to the Lean-N-Clean® / Acidgone® smoothies?
Protein-rich foods induce copious amount of acid into the stomach because protein is mainly digested in the stomach. As a result, if you mix protein powder and nut butter with Lean-N-Clean® / Acidgone®, it will not be as effective for acid reflux/GERD. Protein powder or nut butters can also cause constipation when mixed with Lean-N-Clean® or Acidgone®.
