Life Extension

Life Extension Food Sensitivity Relief with Diamine Oxidase (DAO), Occasional Gas, Digestive Comfort, histamine Sensitivity, DAO Enzyme Supplement, Gluten Free, Non-GMO, Vegetarian, 60 Capsules

Life Extension

$28.50

More Details
Main highlights
- Plant-based DAO – Many DAO formulas utilize enzymes derived from animals (usually pork). But our formula uses diamine oxidase from pea sprouts.
- Live your healthiest life – We believe the answers to a healthier life are in reach, and that scientific research is the key to getting there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
- Ingredients matter – We use the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Histamine metabolism – Diamine oxidase supports the healthy breakdown of intestinal histamine. This in turn helps relieve occasional non-allergy digestive discomfort associated with dietary histamine sensitivity.
- Gastrointestinal comfort – Get relief from occasional gas and stomach upset, as well as other gastrointestinal discomforts caused by histamine-rich foods like cured meats, cheese and wine
