Key Benefits and Actions*

  • May help support digestion of food-derived histamine in the digestive tract
  • Enhances the presence of diamine oxidase (enzyme) in the digestive tract
  • Patented material with optimized stability
  • May help support normal inflammatory responses in the digestive tract

Histamine Block is now packaged in a moisture-controlled, desiccated bottle for enhanced product stability and potency. This new packaging delivers unparalleled protection for products that are sensitive to outside moisture. A desiccant sleeve surrounds the product creating an impenetrable barrier, contributing to greater product stability over time. Research has shown this container system to be more effective than standard bottles containing desiccants or even blister packs.

Histamine Block by Seeking Health contains a patented enzyme formula providing 10,000 HDU of diamine oxidase (DAO) - the main enzyme responsible for the degradation of ingested histamine - per capsule. Histamine is known as a biogenic amine, an organic nitrogen compound, involved in certain immune responses and found in mast cells. It may be involved in regulating healthy function in the GI tract as well as the nervous system. Histamine also plays an important role in triggering the body’s normal inflammatory response.

An excess of histamine can be problematic, however, leading to histamine sensitivity/intolerance, digestive concerns, allergies, and more. Individual sensitivity to histamine varies, and some individuals may be more reactive to histamines and other biogenic amines in foods. Diamine oxidase (DAO) has been clinically tested and found to break down food-derived histamine in the digestive tract. Note that DAO is not absorbed and does not have systemic activity. Histamine Block does not manage or address antibody-related or IgE-related food allergies.*

For a similar formula with added cofactor nutrients, try Histamine Block Plus.

To help maintain your body's natural first line of defense against ingested histamine - your gut - try ProBiota HistaminX.* 

Suggested Use

Take 1 capsule no more than 15 minutes before the consumption of histamine-rich foods, or take as directed by your healthcare professional.

1. Who is Histamine Block intended for?

Histamine Block is intended for those who experience sensitivity to histamine due to intake of excess histamine from non-allergenic food sources.

Excess histamine can be problematic, resulting in sensitivity or intolerance, digestive concerns, allergies, and more. DAO is clinically tested to break down food-derived histamine in the digestive tract, making it easier to tolerate histamine-rich foods. Histamine block does not reduce reaction to true allergies or IgE immune-driven responses.*

The purpose of Histamine Block is to break down histamine in foods with high histamine content (does not reduce reaction to allergies or IgE immune-driven responses). For additional defense against ingested histamines, try ProBiota HistaminX.*

Always talk to your doctor before considering the use of this product, especially if you have health conditions or diseases that need to be addressed or are pregnant or breastfeeding.

2. How do I take Histamine Block?

Take 1 to 2 capsules no more than 15 minutes before the consumption of histamine-rich foods or drinks, or as directed by your healthcare provider. Do not take Histamine Block and knowingly eat foods you are allergic to—it will not prevent allergic reactions.

3. What is the reasoning for each ingredient in Histamine Block?

Vitamin C Assists DAO in breaking down food-derived histamine in the digestive tract.*
DAO (diamine oxidase) Breaks down food-derived histamine in the digestive tract.*

  • Microcrystalline cellulose: Structure of capsule.
  • vegetable capsule (hypromellose, water, and gellan gum)

4. What are the ingredients in Histamine Block derived from?

6. Is Histamine Block free from GMOs?

Can drink beer again!

While I know it’s still not the best for me to have alcohol every once in awhile I like enjoying a glass. I’ve noticed that when I take this I get way less flushed and red in the face! My usual rash on my face is less prominent too. It’s a great back up when I know I’m going to be naughty!

Slow DAO, this helps!

The original DAO supplement, I have found this to be such a help. My cheeks and chin get flushed after eating meals sometimes, and it's not "allergy" so much as histamine for me. I know I have a slow DAO and am very grateful for this product! Even with the new version Histamine Block Plus coming out that has the added cofactors, I still plan to purchase this one AND the other one - this one will be for evening needs, and the other one for my mid-day ones. (The Plus version contains some niacin and I want to be mindful of not taking B vitamins too close to bedtime) It says to take these no more than 30 minutes before eating, but I find it is helpful even after my face flushes after a meal - this way I don't have to take it with EVERY meal, just those meals that give me the extra histamine flush.
