Supports Healthy Degradation of Food-Derived Histamine*
Histamine Support is an enzyme formula containing diamine oxidase (DAO)—the main enzyme responsible for the degradation of ingested histamine.
This enzyme has been clinically tested and found to break down food-derived histamine in the digestive tract. DAO is not absorbed and does not have systemic activity.
Histamine Support does not manage or address antibody-related or IgE-related food allergies.*
Histamine is a bioactive amine-signaling molecule generated in the body in response to allergens, injuries, foreign substances, and alcohol.
It has an array of physiological effects, including increased blood supply to sites in the body that cause reactions such as itching and flushing of the skin, low or high blood pressure, rapid heartbeat, headache, and other symptoms typically experienced in individuals with allergies.
Apart from its role in the inflammatory response, histamine can have varied systemic effects ranging from increased stomach acid production, blood vessel permeability, contraction of smooth muscle tissues, and immune cell modulation.
The highest histamine concentrations in the body are found in the gastrointestinal (GI) tract, lungs, and skin, with lesser amounts in the brain and heart. Two enzymes work within the body to counteract the effects of excess histamine.
Histamine-N-methyltransferase works throughout the body, including in the brain, to break down histamine created intracellularly, and the digestive enzyme diamine oxidase (DAO) breaks down exogenous histamine that enters the body through food consumption.
Histamine is present in various concentrations in many foods, but most notably in fermented foods, such as sauerkraut, sausage, cheese, yogurt, and alcoholic beverages. Certain drugs and non-histamine–containing foods can also play a role by promoting histamine release or inhibiting DAO.
Primarily active in the small intestine, DAO degrades histamine to the inactive metabolite imidazole acetaldehyde to control the histamine burden from food, supporting a steady histamine balance.
In individuals lacking in DAO, a disproportionate accumulation of plasma histamine can lead to a range of adverse symptoms and may result in histamine intolerance (HIT)—a type of food intolerance resulting from excess histamine ingestion.
A person’s histamine tolerance varies according to their threshold, which is how much histamine their body can tolerate before experiencing symptoms. Detailed questionnaires, food intake logs, trials with a low-histamine diet, and measurements of DAO and histamine can help assess HIT.
An estimated 1% of the population has HIT, and most are middle-aged or older.
It has been suggested that individuals with DAO deficiency are often unaware of its existence, meaning that it could be more widespread than known.
Food intolerances, such as HIT, can be much more difficult to pinpoint than food allergies; when an individual has HIT, the reaction is typically dependent on the build-up of histamine and an individual’s histamine threshold, whereas with food allergies, an immune response occurs almost immediately after ingesting the allergenic food.
Additionally, genetic and environmental factors influence DAO metabolism and histamine tolerance. Individuals with GI conditions, those with inflammatory skin and respiratory conditions, and those taking certain medications may be at higher risk for altered DAO production.
Supplementation with DAO has been well-studied and appears to have a viable role in supporting individuals who may be deficient in this histamine-degrading enzyme.
Headaches are one of the most frequently reported symptoms related to HIT.
In a double-blind, randomized trial, subjects (N = 100) who regularly experienced episodic migraines and were found to have a DAO deficiency assessed through plasma testing were given supplements containing 20,000 histamine digesting units (HDU) of DAO per dose for 1 month. Compared with placebo, subjects receiving the DAO supplements exhibited a significantly reduced duration of their migraine attacks.
Histamine Support contains a multi-patented, gastro-resistant source of diamine oxidase (DAO) provided at the clinically researched dose of 20,000 HDU in an easy-to-swallow mini-tablet. This formula was designed to deliver an exogenous source of DAO to the small intestine, where it supports the degradation of dietary histamines.
Histamine Support is not a formula for use by individuals with diagnosed immune-related food allergies (eg, peanuts, shellfish, etc.).*
DIRECTIONS: Take one tablet no more than 15 minutes before the consumption of histamine-rich foods, or take as directed by your healthcare professional. Consult your healthcare professional prior to use. Individuals taking medication should discuss potential interactions with their healthcare professional. Avoid if allergic to pork or any other ingredient.
Histamine Support is NOT EFFECTIVE for symptoms of immune-related food allergies, such as peanuts, shellfish, etc., or for gluten intolerance due to sensitivity or celiac disease.
STORAGE: Keep closed in a cool, dry place out of reach of children.
FORMULATED TO EXCLUDE: Wheat, gluten, corn, yeast, soy, dairy products, fish, shellfish, peanuts, tree nuts, egg, sesame, ingredients derived from genetically modified organisms (GMOs), artificial colors, and artificial sweeteners.

Therapeutic formulas for best results.
As a Board-Certified Internal Medicine physician, I offer pharmaceutical grade nutritional supplements. This means they are typically stronger in potency and higher in quality than supplements you’ll find in most retail or online stores. It also means you can expect to achieve greater results.
Quality ingredients and formulations. Pure and simple.
The ingredients have been tested for purity, quality, potency, and composition, so you can trust the identity of each formula. It’s so important to know that what you are putting in your body is the purest form and highest quality. I would want nothing less for myself, my patients, or for you.
The ingredients and formulations in my products are from wholesome, pure, clean sources, and in their most bioavailable forms for maximum effectiveness. This means that they are in the form that is best absorbed and utilized by your body.
It’s not just what’s in the supplement that matters - what's not in the supplement is just as important. Many of my patients, including myself, have food allergies or sensitivities. None of my supplements contain gluten, dairy, GMOs, preservatives, dyes or toxins.
There are a couple of rare exceptions where products contain trace amounts of egg and a few contain tree nuts. All ingredients are clearly indicated on the product pages. Be sure to read carefully if you have any known food allergies or sensitivities.
Highest manufacturing standards.
The supplements in my store are manufactured in facilities that are strictly controlled by rigorous standards that meet cGMPs, and routinely pass FDA and third-party audits. Materials go through laboratory testing from raw source to the finished product…to bottling and labeling.
I offer the best of the best, from all over the country.
In order to provide a comprehensive array of supplements I don’t rely on just one manufacturer. I recognize that some have better sources and formulations in specific areas than others, and I only select the best of the best. This means, you don’t have to go researching and searching – I've done all the leg work for you.
It’s taken many years of research, trial, implementation, and relationship building to bring what I am offering to you and to my patients. I also stay on top of the latest advancements in formulas, science and industry news to continue to offer the highest quality of innovative supplements. This means you will see changes in offerings to reflect cutting edge solutions.
Evidence-based. Supplements that offer real health solutions.
I personally select every product on my store. Ultimately, it is the science, research and clinical testing that drives my choices and recommendations.
Also, I choose what works. In my years of experience, I have observed the positive outcomes of many of these formulas with patients. In my practice I look for the most natural methods to address health concerns - and often key nutrients and supplements are a huge part of the solution.
I am truly passionate about helping you achieve your best health. I hope you find the nutritional supplements you are looking for and that you are satisfied with your purchase.
