A Key to Histamine Intolerance Management

Histamine intolerance disrupts lives, causing an array of uncomfortable symptoms. A common culprit is often a deficiency in the enzyme, Diamine Oxidase (DAO). When DAO levels are low, histamine levels can spike, causing symptoms. Luckily, supplements can help manage this issue.

This piece provides a beginner’s guide to the standard process of taking DAO supplements, hoping to set the stage for improved health and well-being.

A Quick DAO Overview

DAO is an enzyme naturally found in the digestive tracts of animals and humans alike. Mainly produced in the intestinal mucosa and kidneys of specific mammals like pigs, the porcine kidney is a popular source of DAO for dietary supplements.

This enzyme has activity in the digestive tract, placenta, and cellular enzymes. DAO, along with Histamine N-Methyltransferase (HMT), is one of the key enzymes breaking down histamine in humans. Its activity relates to various digestive and respiratory symptoms.

DAO enzymes are crucial in breaking down histamine, a compound found in various food types, which can cause a range of symptoms in people sensitive to it. When DAO is insufficient, a condition called histamine intolerance (HIT) can occur. This leads to histamine buildup in the bloodstream, causing various symptoms.

The DAO Enzymes’ Role in the Body

Beyond breaking down histamine, the DAO enzyme also associates with other physiological processes like blood pressure regulation and polyamine metabolism. These compounds play roles in cellular growth and differentiation. Some research even suggests that changes in DAO activity could relate to specific medical conditions like asthma and migraines.

DAO Enzyme and Histamine Intolerance

When DAO activity is low, excess histamine can build up in the body, a condition commonly known as histamine intolerance. HIT can result in various symptoms like abdominal pain, digestive issues, respiratory problems, headaches, nasal congestion, and skin rash. In some cases, it might lead to severe symptoms like anaphylaxis.

Several factors can contribute to histamine intolerance, including:

  • Genetics – Some people might have a genetic predisposition to lower DAO activity levels.
  • Diet – Foods high in histamine or substances interfering with DAO production or release can trigger a histamine response and worsen symptoms.
  • Medical conditions – Some medical conditions, like celiac disease and inflammatory bowel disease, may reduce the body’s DAO production and increase the risk of histamine intolerance.

Symptoms of Histamine Intolerance

Histamine intolerance can cause various symptoms, making diagnosis tricky as they might mimic symptoms of other medical conditions. Common histamine intolerance symptoms include:

  • Abdominal pain
  • Digestive symptoms such as diarrhea and nausea
  • Skin rashes
  • Flushing
  • Headaches
  • Nasal congestion
  • Respiratory symptoms like wheezing and shortness of breath

These symptoms might appear immediately after consuming histamine-rich foods or several hours later, complicating the identification of the root cause.

DAO Supplements’ Role in Managing Histamine Intolerance

DAO supplements are supplements where DAO is the active ingredient responsible for breaking down histamine in the body. One of the benefits of DAO supplements is they can be taken preventively before eating histamine-rich or DAO-production-inhibiting foods. This allows people with histamine intolerance to better manage their symptoms and enjoy a more diverse diet.

DAO supplements like DAO-HIST from SeeBeyond Shop contain DAO sourced from porcine kidneys, mirroring the human body’s natural histamine degradation process. Users have reported significant symptom relief, emphasizing DAO-HIST’s effectiveness. Consult with one of our healthcare professionals to start your supplement regimen today.

If you’re thinking about taking DAO supplements to manage histamine intolerance effects, it’s vital to follow the standard process to achieve maximum results. Here’s a step-by-step guide on how to take DAO supplements:

Step 1: Have a Chat with a Healthcare Provider

Before starting any new supplement regimen, you should have a conversation with a healthcare provider like the experts at SeeBeyond Shop. They can offer insights into whether DAO supplements are right for you and how they might interact with any medications or health conditions you have.

Step 2: Figure Out Your Dosage

The recommended dosage for DAO supplements varies depending on the brand. Make sure you read the label carefully and follow the instructions. The average dosage is typically 1-2 capsules per meal, but this could be adjusted based on your specific needs.

Step 3: Take DAO Supplements with Meals

DAO supplements work best when taken with meals that are high in histamine or might block DAO production or release. Foods like fermented or aged cheese, alcohol, and processed meats fall into this category. Taking DAO supplements about 10-15 minutes before a meal can help enhance its effectiveness.

Step 4: Keep It Consistent

For best results, you need to take DAO supplements consistently. It’s recommended to take DAO supplements with every meal that contains histamine-rich foods, without exceeding the recommended dose.

By following this standard process, you can make the most of DAO supplements and manage your histamine intolerance symptoms more effectively.

Key Things to Remember in the DAO Supplement Standard Process

There are a few key points to keep in mind when taking DAO supplements:

1. Diet

Diet plays a critical role in DAO activity. Some foods may inhibit DAO production or release, leading to a higher risk of histamine intolerance symptoms. It’s important to limit or avoid these foods to allow optimal DAO activity and histamine degradation in the digestive tract.

On the flip side, some foods may support DAO activity and help reduce the risk of histamine intolerance symptoms. Fresh vegetables and fruits, lean meats, wild-caught fish, nuts, seeds, and whole grains are good examples. Consuming foods high in vitamin C, copper, and B vitamins can also support DAO activity.

2. Underlying Health Conditions

Certain health conditions like leaky gut syndrome, autoimmune disorders, and allergies can affect DAO function and might require additional support. Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antidepressants, may also inhibit DAO activity.

3. Chat with a Healthcare Professional

Before starting any new supplement regimen, it’s always a good idea to have a chat with a healthcare provider. This way, you’ll have additional guidance on how to incorporate DAO supplements into your overall health plan to achieve your desired results.

Managing Possible Side Effects of DAO Supplements

While DAO supplements are generally safe for most patients, there are a few potential side effects to watch out for:

1. Nausea

Some people might experience nausea after taking DAO supplements. This is because DAO supplements break down histamine, which can impact the digestive system and cause nausea in some people.

2. Headaches

Headaches are one of the possible side effects of DAO supplements, which might be due to changes in blood flow or other physiological factors.

3. Skin rash or itching

In rare cases, DAO supplements might cause allergic reactions. This could result in a skin rash or itching, possibly because of the immune system’s response to the supplement.

Remember that while these side effects aren’t common, they can still occur in some individuals. If you encounter any of these symptoms after taking DAO supplements, it’s advisable to chat with your healthcare provider.

Also, it’s crucial to choose high-quality DAO supplements from trusted sources to ensure their purity and effectiveness. The SeeBeyond Shop offers a wide range of high-quality DAO supplements designed to help individuals manage histamine intolerance. So, why wait? Begin your journey towards a more comfortable life today!


In conclusion, DAO supplements have demonstrated beneficial impacts on managing symptoms of histamine intolerance. However, it’s crucial to remember potential side effects which necessitate medical attention. Consultation with a healthcare provider is advised before beginning supplementation.

DAO supplements are not a substitute for a balanced diet and lifestyle modifications. These are essential for addressing histamine intolerance’s root cause. With proper side effects management, DAO supplements can improve the quality of life for those struggling with histamine intolerance.
