Histamine just got a whole lot easier to manage.
Whether you're just starting out or know what you need, Tolerance is here for you. At-home genetic testing, access to dietary experts, food and recipe advice and DAO enzyme supplements.
WHAT IS HISTAMINE
Everything you need to know.
Histamine is a chemical your immune system releases, also found in certain food and drink.
Some people have a hard time breaking it down when it's ingested. As a result, it can build up and can cause our body's 'histamine bucket' to fill up.
If our bodies can't break it down quickly enough, the bucket can overflow and can cause a histamine intolerance.
Meat, fish, wine and cheese are some of the most common high histamine foods and drink.

The histamine experts
Why we built Tolerance
End-to-end support for food intolerances.
We wanted information and support as we navigated our own digestive issues, and we found that there wasn't one single place where we could get all the information we wanted or needed. So we built it.
