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.

    • Great! Fast ship! *ALLERGIC REACTION !

      from Sprague, WA on 5/21/2022
      I’m super sensitive and allergic to many things. I had a bad reaction to this product. I did consult with my Dr. before use. We were hopeful that it would work. Reaction affected my cardiovascular system, stroke related. It would be wise to consult with your Dr. first before use. Unfortunately giving 1 star for product. Had a smooth transaction purchasing this product with a quick return on shipping. Item as described and was sealed. 5 Stars!!!

      Pros

      It likely works for most people

      Cons

      Beware if you’re sensitive and have allergies

      Great

      from LAKEWOOD CO on 1/26/2022
      I take one capsule before eating dairy. I have an allergy to casein, the protein in dairy. These solve the problem!

      Pros

      These work!

      Cons

      I have no complaints.

      Great Product

      from IL on 1/01/2022
      This product is great. The only reason I did not give it five stars is because it is so expensive. I wish a company could make a histamine blocking supplement that would be affordable to everyone. At $0.85 a pill, it really adds up when you have to take it at every meal.

      Pros

      It helps with histamine food intolerances.

      Cons

      Way too expensive!

      Great Product

      from Alaska on 10/05/2021
      Used last month and found it helped me avoid bad sinus problems and head fog associated with eating certain foods. I also added Quercetin and Bromelain to the mix, and now my nose is as dry as a whistle!

      Pros

      Works well, improves quality of life with allergies

      Cons

      Wish I could get more capsules for the $$$

      I take to tablets before I eat to control histamines. For me it prevents getting an irregular heartbeat.

      Pros

      It works every time.

      Cons

      If I forget to take it, I get an irregular heartbeat.

    • Good product, great packing

      from Maryland on 2/26/2021
      I take Histamine Block for histamine intolerance and it's very helpful. My order arrived promptly. I want to commend Pure Formulas for using 100% biodegradable paper packing - wish more companies would do this.

      Pros

      Cons

    • Gives back freedom to eat with others

      from Alaska on 1/15/2021
      One pill taken 10 min before a meal greatly reduces the histamine reaction I would normally have with certain foods. This allows me to eat at parties or restaurants when I don't know exactly how things have been prepared. All but the strongest of my chemical sensitivities are undetectable when taking Histamine Block. One warning: it really does have to be taken before I eat to offer the full benefit. I have sometimes forgotten until halfway through the meal and I can end up with a headache or patch of hives anyway, so keep it in the kitchen or on your person when you are out. Its easy to forget.

      Pros

      I like that I can take this and it helps even though I still have histamine intolerance. It improves my quality of life NOW, even as I work to repair the cause of my issues. It does not cure any condition, but it allows me to go out with friends and share in the traditional family meals, such a gift during the holidays especially. It becomes very tiresome to always be eating something different from everyone else.

      Cons

      It is still expensive per pill. This was an excellent price compared to what I've seen elsewhere, or for similar products, but it still adds up if you take it very often. I usually take only one or less per day unless I am traveling or staying with others and have no control over the foods I am given.
