Solaray Vegan DAO Enzyme Really Makes a Difference
"I have Histamine Intolerance, and have tried several different DAO enzyme products over the last several years, along with modifying my diet to limit both high histamine foods and histamine liberators. All of this moved the needle somewhat , but not as much as I'd hoped for. I decided to try Solary's DAO Enzyme a few months back, and it really has made a significant difference. Much less bloating, and I am even able to bring back some foods that I had eliminated for so long. A game changer!"
— Miryam B. (5/5)
