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 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. DAO is not absorbed and does not have systemic activity. Histamine Block does not manage or address antibody-related or IgE-related food allergies.

      My 26 yo Daughter was experiencing bloating and nausea everyday for 6 years. She noticed she was worse when she ate any left over foods, esp greater than 6 hours old. Finally we saw a functional medicine Dr. that advised her that she may have a histamine issue. She maybe unable to break down Histamine present in foods ( it increases as food sits). He recommended she take Histamine Block made with DAO. Take it before each meal. She has noticed a big difference. Next -- to work on correcting her Disbiosis.

      my nutritionist recommended these to help prevent food allergy/sensitivity symptoms. I have noticed a difference (less stuffiness and GI discomfort) when taken shortly before consuming some things such as red wine. Since I am uncertain of what exactly causes some of my symptoms I can't say for sure if this is helping.

      Pros

      seems to help prevent full-blown symptoms

      Cons

      I would recommend this item to a friend.

      I wasn't expecting too much from this product, but I was hoping it would help at least a little. I have so many allergies due to Leaky Gut, IBS, S.I.B.O., in addition to a High Histamine producing body! My immune system go on an all-out defense attack against itself. I was ready to try something that might help. I am now on my second bottle of DAO/Histamine Block and it seems to be lessening the severity of some of my reactions. Not sure how much worse the ones that are being lessened would be, but I know that I had longer lasting reactions before starting the DAO. There are so many variables related to each reaction. However, I do know this: if I do not vary from my diet too much (eating only one low allergy food per day) I have a lesser reaction to the offensive food then I did before. I was told I could take 2 pills per meal if I needed to, but that would too expensive! I told myself that if it gets too expensive to continue I'll just back-off the allergy foods for as many days as I need to and then add it again later. The point is to try to have a greater variety of foods/nutrients in my diet whatever way it works out in the end. Hope this helps someone.

      Pros

      Helps relieve some of the harsh allergic reactions I experience to some of the pure and fresh nutritious foods I need to eat.

      Cons

      Soo expensive! And the fact that I have to open the capsules to avoid the offensive chemicals on the outside of the "time-released" capsules and take with my meal.
