Diamine oxidase (DAO enzyme) is a histamine degrading enzyme that is commonly low in people with histamine intolerance, either through hindered production or genetic deficiency.

DAO is responsible for breaking down histamine in the body. If DAO levels are low, histamine will not be properly degraded, causing levels of histamine in the body to become too high and produce histamine intolerance symptoms.

DAO specifically targets histamine ingested through food or environmental exposures, therefore insufficient levels of DAO can result in reactions to histamine-containing foods, products and even contribute to seasonal allergies.

Supplementing with DAO has shown to assist with breaking down histamine in the body to reduce overall histamine levels. This process can improve symptoms for those experiencing histamine intolerance related issues.

This supplement is manufactured in the USA using only the highest quality ingredients. It is tested for potency and purity to guarantee quality and efficacy.

    Why I Created My Own Supplements

    I’m Anita, the nutritional scientist behind Unitee!

    Unitee is the world’s first supplement line made specifically for histamine intolerance. For nearly a decade, I’ve helped people to solve histamine intolerance, naturally.

    Before Unitee, I would cherry-pick supplements from brands that just happened to carry a histamine-safe product or two. I was constantly double checking if each brand had changed ingredients, sold out or discontinued their products.

    It often left people having to wait for or part with supplements they relied upon. Your body deserves better, and you deserve a brand to count on.

    After years of experience formulating for some of the world’s greatest supplement brands, I decided to create Unitee: a clean, science-backed, high quality supplement line made solely for histamine intolerance.

    So grateful for your supplements. Especially keeping your prices at an affordable rate

    Renee Akande

    I am so sorry. No one's fault. I appreciate you sending me the dao enzyme, your patience. It did not help me at all. I became sick after taking it I only took one with each meal instead of taking two that was suggested. I only took it with two meals for one day, and the next day, I experienced pain all over.Had a really hard time. All I can think is perhaps I don't have Mast cell activation and histamine intolerance or overproduction.. The enzyme gave me symptoms of MCAS.

    Not sure

    do not notice too much difference so far


    Contains grains that I CAN’T eat and they were very uncaring when I asked if they had plans to make a grain-free line.
