Histamine Intolerance & Hives 

Histamine Intolerance is a common issue that manifests with symptoms such as hives, irritability, profuse sweating or becoming red in the face when exercising, exercise-induced asthma, psoriasis, eczema, insomnia, nosebleeds, anxiety, and sweaty hands and feet.

Too much histamine in your body can contribute to symptoms such as flushing, runny nose, sleep difficulties, and/or headaches. These pesky symptoms can be the result of slowed enzyme activity in your histamine pathway. 

Some people react to food-derived histamines (fermented foods, aged cheese, wine, etc.). 

Others are more sensitive to the histamines created by probiotics or gut bacteria. 

And still, others are sensitive to histamines in their environment (seasonal sinus issues, runny nose, etc.)


Dietary changes and environmental factors are thought to contribute to the increase in allergies seen over recent years. Increased consumption of a “Western diet” including fewer fruits and vegetables and more processed grains, fats and meats leads to a significant decrease in dietary intakes of beneficial compounds such as flavonoids, antioxidants, and polyphenols found in fresh fruits and vegetables.

Histamine-containing foods: Histamine, a part of the body’s biological defense system, is also found in many common dietary sources such as fish, meat, cheese, fermented foods such as miso, pickles,

sauerkraut, aged food such as parmesan, smoked food such as smoked salmon, red wine, champagne, fish, acid food such as tomatoes, citrus fruit, vinegar, alcohol, citrus juices, and leftovers.

🌸Avoid aged, fermented food. Eat only the freshest meat and fish available to you. 

🌸Avoid aged cheese especially parmesan, considered a great offender.  


Other foods contain histidine, which is converted to histamine during digestion by certain bacteria in the gut. At healthy levels and in the right places, histamine is needed for a normal digestive process and sleep-wake cycle, and for a functioning immune system. On the other hand, too much histamine can cause unpleasant side effects like rashes, itching, stuffy nose, swelling, headache, and gastrointestinal complaints.*

Environmental Stress worsens histamine intolerance can also contribute.

For me, it is conventional laundry products smell coming from neighbor's laundry rooms.

  • Choose always organic laundry products. I hope there will be more awareness and protection from unhealthy cause-effect from fragrances.

  • If you are allergic to dust mites wash your bed sheets with water at higher temperatures.  

  • Choose organic skincare and organic hair products without harsh preservatives such as sodium benzoate classified 3 on ewg.org, identified as capable of causing contact urticaria.

Enzyme DAO and HNMT

People with histamine intolerance often have low levels of either of two very specific enzymes—diamine oxidase (DAO) and histamine-N-methyltransferase (HNMT)—that process histamine in your body.

Some of us people do not produce enough of this important enzyme called DAO, produced by our digestive system to help break down histamine.

For this reason, we need to follow a low-Histamine diet, avoid external stressors,s and supplements with anti-histamine supplements.


I listed here all the products to help you with histamine. I found them to great for my occasional hives.

I also create a diary where I record the food I had after a hives episode to help to spot the food that creates intolerance.

🌸 A healthy gut is a key factor in normal histamine metabolism and healthy histamine levels throughout the body.*

Pure Encapsulations Quercetin 
organic quercetin, organic anti-histamine

Many of us have histamine intolerance issues caused by dietary and environmental factors!
It can show as allergy, sinus, skin reactions such as eczema, psoriasis, hives.
Quercetin is my new discovery!
Quercetin is found in foods such as broccoli, parsley, artichokes, butternut squash.
Quercetin belongs to a class of water-soluble plant pigments called bioflavonoids that cannot be produced by the human body. This quercetin is derived from Fava d’ anta tree.
Recommended for many functions such as supporting healthy enzyme activity, it contains one of the most bioactive bioflavonoids.
It is also great for workouts!
It offers immune support
Antioxidants support
Cellular support and maintain mast cell function!
It is part of my supplement collection!

Pure EncapsulationVitamin C 
organic supplement, pure encapsulations, essential-C

🌸 The majority of Vitamin C available on the market is made by a cheap form of Ascorbic Acid and it acid for our stomach. I found this version made instead of calcium ascorbate.

This Vitamin C is great since it has quercetin in it.

🌸Vitamin C is a great antioxidant that supports the immune system and the reaction to Histamine as well as healthy cell function. 

Antioxidant Support: Includes bioflavonoids, quercetin, and rutin, which are free radical scavengers that complement the role of vitamin C

This Vitamin C provides highly absorbable vitamin C better forms since it is a non-acid version, great if you have acid-reflux -GERD.

🌸This is Gluten-free, Vegan without added fillers. Made with hypoallergenic, vegan ingredients

Coronavirus: it is recommended to boost the immune system for this virus as well.

Vitamin B6  by Pure Encapsulatin

🌸 Vitamin B6 works for Instamine intolerance.

Activated Vitamin B6 to Support Metabolism of Carbohydrates, Fats, and Proteins.

Vitamin B6 is often mentioned as help to be relieved from high histamine levels, due to its important role in the breakdown of histamine by DAO.

🌸Vitamin B6 50 mg once daily.
Note: never exceed the recommended dose.

Your body needs Vitamin C and vitamin B6 to manufacture the DAO enzyme, which helps break down histamine in the body. Remember to use a low acid Vitamin C, avoid the cheap ascorbic acid form. Better even if you have acid reflux or GERD.
