Quick Facts

Who HistaGest DAO Is For

• Adults looking to reduce histamine intolerance symptoms
• People who react to histamine-rich foods such as aged cheese, cured meats, wine or fermented foods
• Anyone wanting digestive support before meals out or while travelling
• Those supporting normal histamine metabolism

Who this product is NOT for:

• Vegetarians, vegans and anyone avoiding pork — the DAO comes from pig kidney extract
• Children and teens — the label dose is for adults 18 years and older
• People who are pregnant or breastfeeding, have a gastrointestinal or cardiovascular disease or disorder, or take anti-inflammatory or histamine-releasing medications or antihistamines, unless advised by a health care practitioner
• Anyone following a low-histamine or histamine-free diet without first checking with a practitioner, as the label advises

Vitamart's Take

HistaGest DAO is a focused tool: one small tablet before a histamine-heavy meal supplies 20,000 HDU of the enzyme your gut uses to break down food histamine. The delayed-release coating matters — it protects the DAO from stomach acid so it reaches the small intestine where it works. The dispenser fits in a pocket or purse, which makes it easy to keep on hand for restaurant meals and travel. Note that it is porcine-sourced, so it is not suitable for vegetarians.

How HistaGest DAO Compares

DAO enzyme vs. antihistamines

Antihistamines block histamine receptors after histamine is already in the body. DAO works in the digestive tract to break down histamine from food before it is absorbed. Ask a practitioner before combining them — the label lists antihistamines as a caution.

Delayed-release vs. standard tablets

DAO needs to reach the small intestine to work. HistaGest DAO uses a gastro-resistant coating, which is why the tablet must not be crushed or chewed.

DAO vs. general digestive enzymes

Broad enzyme blends such as Designs for Health Plant Enzyme Digestive Formula target protein, fat and carbohydrate digestion. DAO targets food-derived histamine specifically.

What Is DAO (Diamine Oxidase)?

• Diamine oxidase (DAO) is the primary enzyme that breaks down histamine in the digestive tract
• Histamine is made naturally in the body and is also found in many foods
• Histamine levels in food can rise through aging, fermentation or storage
• Taking DAO before meals supports the breakdown of food-derived histamine as it enters the digestive tract
• HistaGest DAO measures its enzyme activity in Histamine Degrading Units (HDU)

Recommended Purpose

• Helps to reduce histamine intolerance symptoms
• Promotes normal histamine metabolism
• Supports the digestion of histamine-containing foods
