For those with multiple sensitivities and higher DAO needs, OmneDiem® Histamine Digest® PureMAX is our purest formulation to date — now delivering 40,000 HDU of pure Diamine Oxidase (DAO), thanks to advancements in our extraction and manufacturing process.*
What it is: A high-potency, single-ingredient DAO enzyme supplement. Each designed-release capsule contains nothing but 4.8 mg of pure DAO (40,000 HDU) plus ultra-purified MCC — no added nutrients, fillers, or excipients — to support your body's natural breakdown of dietary histamine in the gut.*
Why Choose PureMAX?
Many foods contain histamine and/or trigger the release of histamine in the gut. Diamine Oxidase (DAO) is the primary enzyme responsible for breaking down dietary histamine. PureMAX delivers natural-source DAO in a designed-release capsule that dissolves in the small intestine — right where it acts directly on dietary histamine to support digestive comfort.* If you're sensitive to multiple ingredients or simply want DAO and nothing else, PureMAX is the cleanest way to get it.

Frequently Asked Questions
What is Histamine Digest PureMAX?
PureMAX is OmneDiem's purest, highest-potency DAO enzyme supplement — 40,000 HDU of pure Diamine Oxidase per capsule with no added nutrients, fillers, or excipients, in a designed-release capsule that releases in the small intestine.*
How is PureMAX different from regular Histamine Digest?
Standard Histamine Digest® provides 30,000 HDU of DAO for everyday support. PureMAX steps up to 40,000 HDU in a single-ingredient, ultra-clean formula — ideal for those with multiple sensitivities or higher DAO needs.*
What is HDU and why does it matter?
HDU (Histamine Degrading Units) measures DAO enzyme activity — the amount of histamine the enzyme can break down. A higher HDU means more histamine-degrading capacity per capsule.*
When should I take PureMAX?
Many people take DAO shortly before eating high-histamine foods or beverages, so the enzyme is active in the small intestine when dietary histamine arrives. Follow the label and consult your healthcare provider for guidance specific to you.
Is PureMAX free of common allergens and additives?
PureMAX is formulated without sugar, dairy, gluten, or artificial additives, and is made in a certified GMP facility in the USA. Note: OmneDiem DAO is porcine-derived, so it is not suitable for pork allergies or vegetarian, vegan, kosher, or halal diets.
