Histamine.

A chemical your immune system releases, also found in certain food and drink.

-------------------------------------

Some people have a hard time breaking down histamine when it's ingested. As a result, it can build up and can cause a histamine intolerance.

Tipping point.

Certain food and drink can cause our body's 'histamine bucket' to fill up. If our bodies can't break the chemical down quickly enough, it can overflow.

Aperitif - Diamine Oxidase Supplement

Aperitif empties the bucket.

Tolerance's leading product, Aperitif, provides your body with 48,000 histamine degrading units (HDUs). It's diamine oxidase (DAO) enzymes help break down high amounts of histamine flowing through your body.

What is diamine oxidase (DAO)?

DAO has one job, and that's to break down histamine.

The enzymes are naturally produced by our bodies and are found in our small intestines, colon, uterus, bladder, prostate and breast milk.

For some people, they either don't have enough of it or the enzymes aren't working properly.

That's where Aperitif comes in. A food supplement that increases the amount of DAO running through the body.
