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.

    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.

    Painful if you are grain-free

    I didn't realize there would be rice flour in the ingredients list - my bad, I should have paid closer attention. But when I reached out to support and asked if they had any plans of producing a grain-free product I was given a small lecture about how a lot of supplements have rice flour. Right. I get it. But I have been using other products with cellulose or silica in place of rice flour because rice makes me ill - my legs get weak and "vibrate" from within, and my gut can't tolerate it. It's not a "choice" for me to omit grains from my diet, so I'd appreciate not getting lectured on how most people can tolerate it. I'm going back to my other supplements. Oh, and no empathy or suggestion that I could get a full or partial refund. I'm not going to be a returning customer. My other supplements work well and I'm going back to them.

    Worked very well until…

    For several years I have had extreme trouble with itching patches. After not getting help through medical professionals, I began searching and researching. I happened on information by Anita Tee @ Fact vs Fitness that seemed promising. So I ordered Anti-Hist. This stopped my problem and worked well. There seems to be another element in play for me and that is stress. When I experience stress and don’t deal well with it I break out. The itching is much better than before.
