Introducing Great Billiom DAO Enzyme
Powerful Formula for Food Sensitivity Relief.
Favorites like pizza, aged cheese, alcohol, cured meats, tomatoes, spinach, shrimp & canned fish can stack up histamine and leave you feeling flushed, stuffy, headachy, bloated or just off.
DAO Enzyme helps your body break down histamine from food in the small intestine before it is absorbed. The result is better food tolerance, smoother digestion, and more comfortable meals.


Food tolerance
Helps your body handle histamine from everyday foods so you can enjoy more and worry less.

Digestion comfort
Eases post-meal discomfort like bloating or queasiness that can follow trigger foods.

Everyday gut support
Promotes calm, predictable digestion when your menu changes day to day.

Reaction relief
Helps reduce common reactions after trigger foods like flushing, stuffy nose, head discomfort, and stomach upset, so you feel normal after meals.
