Full Description

Do you ever get uncomfortable symptoms after ingesting the following high-histamine foods?

Cured meats


Aged cheeses







You might be experiencing symptoms of histamine intolerance. This can include headaches, hives, gastrointestinal issues, heart palpitations, skin issues, bloating, sneezing, runny nose, and more.

The above foods are rich in a naturally occurring compound called histamine. Normally, an enzyme in your gut breaks down histamine from your diet. This enzyme is called Diamine Oxidase or DAO.

Some people, due to genetics or other factors, do not produce enough DAO enzymes. As a result, they may experience uncomfortable symptoms when eating high-histamine foods. Supplementation with DAO may provide support in susceptible individuals.

Histamine Block contains a patented enzyme formula featuring diamine oxidase (DAO). When taken with meals, it can help alleviate symptoms related to high-histamine foods.

DAO has been shown to break down food-derived histamine in the digestive tract. Thus, DAO supplements can make it a lot easier to tolerate histamine-rich foods. Don’t let your meal choices disturb your day. Now you can enjoy delicious family and vacation meals with confidence!

Usage Directions

Take 1 capsule, as needed, just prior to consuming high histamine foods or drinks. Or, take away from food if wanting to support healthy histamine levels in the digestive tract.

Do not take Histamine Block without food or drink, OR with low histamine foods or drinks, unless:

you know that your microbiome is producing histamine

you have inflammatory processes found in the digestive tract, specifically small or large intestines, which may contribute to high histamine levels.

Use as directed by your healthcare professional.
