Anti-Hist provides a blend of antioxidants, enzymes, flavonoids and botanicals to support symptoms involved with excess histamine load such as seasonal allergies, respiratory issues and other symptoms associated with histamine intolerance.

This supplement is an all-natural antihistamine that has shown to be powerful and effective among our histamine intolerant clients, helping them to tolerate more foods with less symptoms. It is by far our most popular and favored supplement, being referred to as a ‘miracle in a bottle’ or an ‘all-natural wonder-drug’ by our community of histamine intolerance sufferers.


Quercetin has strong antioxidant activity and has been shown to support immune health by mediating the release of inflammatory compounds including leukotrienes and prostaglandins. Quercetin is known for its ability to stabilize mast cells, diminishing the release of histamine, the compound known to cause hypersensitivity reactions during seasonal changes.

Stinging Nettles Leaf Extract

Stinging nettles leaf is a plant that has been shown to balance immune response, specifically in the airways and nasal passages. Studies have shown that the extract of stinging nettles leaf balances a variety of inflammatory activities that affect respiratory health.


Bromelain is a plant enzyme naturally found on the stem and fruit of the pineapple plant. Bromelain is a proteolytic (protein-digesting) enzyme that aids in in the breakdown of large protein complexes, including antigenic compounds, and has been shown to enhance the absorption of quercetin. Bromelain has been shown to reduce circulating allergenic protein complexes associated with hyper-immune sensitivity and seasonal discomfort.

Vitamin C

Vitamin C cannot be synthesized by humans and is therefore an essential nutrient that must be consumed in the diet. Among its numerous health-promoting properties, vitamin C is an essential vitamin that supports the immune system and is also a potent antioxidant. When the body is under a significant amount of stress, vitamin C is excreted rapidly. Vitamin C has many immune boosting properties, but is distinctively beneficial for individuals with seasonal discomfort because of its ability to deactivate histamine.

    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.

    Anti Hist

    I don't like the way this product makes me feel. After a few days, I had to stop taking it because it made me feel itchy and headachy.

    Guillermo Zapata

    My hives have calmed down

    Jesse Battino
    Anti- Hist

    Product appears to be excellent from an ingredient standpoint but I have not seen any noticeable difference.

    Mia McCarville

    I’m still trying to figure out how much I can venture out with histamine food and liberators.
    It seems Anti-Hist speeds up the recovery from flare ups.


    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.
