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
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
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.

Anti-Hist FAQs
What is Anti-Hist and how does it support allergy symptom relief?
Anti-Hist is a natural antihistamine supplement formulated to support people experiencing common allergy symptoms, including sneezing, itchy eyes, and a runny nose, particularly during allergy season. It works by supporting the body in regulating histamine release, which is a key driver behind many allergic reactions and allergic symptoms. By using carefully selected natural substances known for their anti-inflammatory properties and antihistamine properties, Anti-Hist is designed to provide gentle allergy symptom relief without relying on pharmaceutical drugs. Many users take Anti-Hist daily to help reduce allergy symptoms and support comfort during periods of increased allergen exposure, particularly those with seasonal allergies or histamine intolerance symptoms.
Can Anti-Hist help with allergic rhinitis and nasal symptoms?
Yes, Anti-Hist is commonly used by individuals dealing with allergic rhinitis, including seasonal and environmental triggers. Allergic rhinitis symptoms often include nasal congestion, sneezing, and ongoing nasal symptoms caused by nasal inflammation and histamine release. The ingredients in Anti-Hist help support a balanced inflammatory response and may help alleviate allergy symptoms linked to hay fever and other allergic diseases and allergy-like disorders, such as histamine intolerance. Many people include Anti-Hist as part of a daily routine during allergy season to support clearer breathing and overall nasal comfort.
How does Anti-Hist work differently from conventional antihistamines?
Unlike conventional medications, Anti-Hist relies on natural substances with recognised anti allergic effects and anti inflammatory activity. Instead of blocking histamine receptors directly, it supports the body’s ability to manage histamine release and allergic inflammation naturally, such as through the stabilization of mast cells which therefore regulates histamine release naturally. This approach may be suitable for those looking to support immune balance without the drowsiness sometimes associated with pharmaceutical options. Anti-Hist focuses on long-term support for people experiencing repeated allergic reactions and allergy-like disorders, rather than short-term symptom masking.
Is Anti-Hist suitable for hay fever and severe seasonal allergies?
Anti-Hist is commonly used by people affected by hay fever and severe seasonal allergies, especially during high-pollen periods. These conditions often cause persistent allergy symptoms, including itchy eyes, runny nose, and nasal congestion. By helping manage histamine release and supporting the body’s anti-inflammatory properties, Anti-Hist may contribute to improved comfort throughout allergy season. Many users incorporate it into their routine alongside other lifestyle adjustments to support consistent allergy relief.
Can Anti-Hist help reduce nasal inflammation and congestion?
Yes, Anti-Hist is designed to support a healthy inflammatory response, which may help reduce nasal inflammation and relieve nasal congestion associated with allergies. These symptoms are often driven by excessive histamine release and immune over-activation. The formulation includes ingredients with anti inflammatory and antihistamine properties that may help support nasal comfort and reduce pressure linked to allergic rhinitis and other allergic diseases and allergy-like disorders.
Does Anti-Hist help with allergy symptoms caused by foods like citrus fruits?
Some individuals experience allergy symptoms or histamine-related reactions after consuming certain foods, including citrus fruits. While Anti-Hist is not a food intolerance treatment, it may help support the body’s response to histamine release and allergic inflammation triggered by dietary factors. Its blend of natural substances and anti inflammatory properties may be helpful for those looking to support overall allergy symptom relief as part of a broader wellness approach.
Can Anti-Hist support people with immunological diseases or allergic diseases?
Anti-Hist is designed to support individuals managing ongoing allergic diseases and certain immunological diseases where histamine activity plays a role. These conditions often involve repeated low level to moderate allergic reactions and chronic allergic inflammation, specifically in relation to an imbalance with or intolerance to histamine. While Anti-Hist is not intended to diagnose or treat medical conditions, it may help support immune balance and provide gentle allergy relief through its anti-inflammatory and antihistamine properties.
How long does it take to notice allergy symptom relief?
The time it takes to experience allergy symptom relief can vary depending on the severity of allergy symptoms and individual sensitivity. Some users report improvements in nasal symptoms, reduced runny nose, and fewer allergic symptoms within days, while others find benefits build gradually with consistent use. Anti-Hist is often taken daily during allergy season to help reduce allergy symptoms over time rather than acting as an instant solution.
Is Anti-Hist based on traditional medicine principles?
Yes, Anti-Hist draws inspiration from traditional medicine, where plant-based ingredients have long been used for their anti inflammatory properties and anti allergic effects. These ingredients have been traditionally associated with supporting immune balance and reducing allergic inflammation. Anti-Hist combines this historical use with modern formulation standards to support people seeking natural approaches to allergy relief.
Who should consider using Anti-Hist?
Anti-Hist may be suitable for adults experiencing recurring allergy symptoms, including hay fever, allergic rhinitis, and seasonal or environmental triggers including the consumption of histamine-containing foods. It is commonly used by individuals with allergy-like disorders such as histamine intolerance, and any issues associated with histamine such as histamine imbalance or sensitivity. Anti-Hist is suited for those looking to support comfort during allergy season, manage nasal congestion, and support the body’s response to histamine release. As with all dietary supplements, Anti-Hist should be used as part of a balanced lifestyle and not as a replacement for medical advice.
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.
Works well.
For years I dealt with red spots on my chest and face and never understood what was going on with my body. FINALLY, I came across this website that taught so much knowledge and helped me understand I have a histamine intolerance. Anti-Hist and the other vitamins I’ve bought have changed my life! I would highly recommend any and all these products if you’ve been dealing with histamine symptoms.
Anti-Hist seems to be a good product. I have re-ordered it.
I try to avoid histamine-high foods. However, there are always times when no matter what, it gets me!!! When that happens I take 1-2 additional capsules in
the night to get some sleep -- and it works!!
I have been struggling and searching for 10 years to find relief! Finally, something that works! When I started using this product along with the reduced histamine diet, everything changed. Now I feel like a normal person. No pain, no issues.
