Histamine Digest® PureMAX.

Nothing But Pure DAO.*

Histamine Digest Puremax

For those with multiple sensitivities and higher Diamine Oxidase (DAO) needs,  OmneDiem® Histamine Digest® PureMAX, our purest formulation to date. With nothing but 4.8 mg of pure DAO, delivering 40,000 HDU of DAO and ultra-purified MCC in our designed release capsules, PureMAX is the choice for those looking for a DAO supplement without added nutrients or excipients. Why the change to 40,000 HDU? click here to learn more.

Many foods contain histamine and/or cause the release of histamine in the gut. Diamine Oxidase (DAO) is the primary enzyme responsible for the breakdown of dietary histamine. OmneDiem® Histamine Digest® PureMAX delivers natural-source DAO in a designed-release capsule that dissolves in the small intestine, where it acts directly on dietary histamine to support digestive health and comfort.*

OmneDiem Histamine Digest PureMax DAOgest Alcohol
OmneDiem Histamine Digest Puremax wine beer

Introducing excess histamine levels. Wine and some beers contain high levels of histamine. 

OmneDiem Histamine Digest Puremax cocktails wine beer release

Liberating histamine. Alcohol is broken down into acetaldehyde, which triggers mast cells to release histamine. 

OmneDiem Histamine Digest Puremax cocktails DAO DAOgest

Blocking the activity of DAO in the gastrointestinal tract. Alcohol inhibits DAO production in the intestines. 

Why the change in HDUs?

OmneDiem Histamine Digest and Histamine Digest PureMAX even more HDUs

Diamine oxidase, like other enzymes, is a delicate molecule that is most active when it is kept away from extreme environments, heat and humidity being two examples. By keeping diamine oxidase’s specific needs in mind, we’ve been able to customize the manufacturing process keeping it more stable and more active during extraction to yield an increased enzymatic activity and more HDU. It is thanks to these improvements in manufacturing that we can obtain a higher enzymatic activity out of the same amount of starting material.

  1. Abbey – March 18, 2021

    Rated 5 out of 5

    I require DAO due to a genetic mutation and the new Histamine Digest PureMax with DAO has been a lifesaver! I could not eat anything without it! I now have a more normal life thanks to Diem Direct and their DAO. Thank you, I will be a lifetime monthly subscriber!

  2. Dianne (verified owner) – July 8, 2021

    Rated 5 out of 5

    I love this product because it has no additives. A lot of companies are adding ascorbyl palmitate to their formulas which I cannot tolerate because it gives me gas chest pain and bloating. This one is the cleanest DAO you will find! I am so glad I discovered DAO because it has dramatically reduced my allergy symptoms – especially the Histamine hot flashes that I always used to get after meals!

    Thank you for making a DAO without vitamin c! I can finally use DAO. Please, dont stop making this!

  4. Stephanie (verified owner) – July 7, 2022

    Rated 5 out of 5

    We were SO GRATEFUL to find a DAO that doesn’t have additives like corn starch or vitamin C! It’s been a complete game changer for me and my daughter. We have MCAS and are allergic to everything and this is one of the only supplements that we tolerate. I can open up capsules and sprinkle a little bit in water for my daughter and it barely tastes like anything. It reduces our allergy symptoms enough that I don’t have to take zyrtec every day, and that improves my quality of life immensely. AMAZING. Thank you.

    Please never stop making this product. It is the first and only DAO I can take with such intense allergies – and it’s been a life saver! Thank you!!

    Histamine Digest Puremax, in my opinion is the best product out there to combat histamine intolerrance. I was taking the other brands also made by DIEM and other companies but was reacting to the additives they contain. This particular brand does not contain additives except MCC in very low quantity and is the purest form I have seen so far in the market. I am VERY grateful to DIEM for developing this product. I am able to take it 2 to 3 times everyday without any side effect and able to eat the food I like anytime as long as I take one or two capsules of Histamine Digest Puremax 15 minutes in advance. It is now part of my daily routine to take this medication before food and I feel very much healthier. Once again, thank you DIEM for developing this product. It is invaluable to me and I will recommend it ahead of any other products currently in the market.

ATTENTION NORTH AMERICAN CUSTOMERS: USMCA and Changes to De Minimis:

The United States-Mexico-Canada Agreement is the treaty replacing NAFTA as of July 1st, 2020.

A significant change was made to the de minimis threshold for international shipments. De minimis is the minimum value of goods item below which no duties and/or taxes are assessed by Customs.

The new de minimis value thresholds for commercial shipments (i.e., UPS) into Canada and Mexico:

  • The new Mexico de minimis threshold is $117 USD for duty and $50 USD for taxes.
  • The new Canada de minimis threshold is $150 CAD for duty and $40 CAD for taxes, only for shipments exported directly from the U.S. or MX (for CA only).
  • The U.S. threshold for importation remains at $800 USD.

For shipments traveling via a postal method (i.e., USPS), the threshold is $300 USD.

  • If the value of the merchandise is $300 USD or less, it is free of any tax or duty under most circumstances. A commercial invoice is preferred, but not required for merchandise valued up to $300 USD.
  • For merchandise with a value over $300 USD and up to $1,000 USD, duties and taxes may apply and a commercial invoice is required.

ATTENTION INTERNATIONAL CUSTOMERS:

  • Please note:  Import duties, taxes and charges are not included in the item price or shipping cost. These charges are the buyer’s responsibility. Please check with your country’s customs office to determine what these additional costs will be prior to buying. Buyer’s failure to accept delivery (including in the event of buyer’s failure to accept delivery from customs owing to import duties, taxes or charges) may, in our sole discretion, mean that the products are not eligible for any refund of buyer’s original payment.  If we do accept a return, any refunds related to such product returns, will be reduced by the shipping costs associated with the returned products.
