Menopause, Histamine & DAO: Introducing OmneDiem's Menopause Complete
Important Notice
This article is for general educational and informational purposes only and is not medical advice. OmneDiem® dietary supplements are not intended to diagnose, treat, cure, or prevent any disease or health condition. These statements have not been evaluated by the Food and Drug Administration.*Many women notice that during their 40s and 50s, foods and drinks they once enjoyed — a glass of red wine, aged cheese, leftovers — seem to sit differently. If that sounds familiar, your changing hormones and your body's histamine-processing system may be talking to each other. Think of estrogen and the histamine-clearing enzyme DAO as two ends of a seesaw: when estrogen swings up during the menopausal transition, your body's natural histamine clearance can dip on the other side.*
Why Histamine-Related Discomfort May Feel Different During Perimenopause and Menopause
Histamine is a natural compound in the body and in many foods and beverages. Normally, an enzyme called diamine oxidase (DAO) helps break down dietary histamine in the gut before it's absorbed (Comas-Basté et al., 2025). The menopausal transition is a natural life stage — not a disease — but the hormonal shifts that come with it may influence how efficiently the body manages histamine.*
The Estrogen–Histamine–DAO Connection, Explained
Research describes a two-way relationship between estrogen and histamine. Estrogen can stimulate the release of histamine, and studies indicate that estrogen may down-regulate DAO activity (Maintz & Novak / female sex hormones & DAO). DAO levels also track the menstrual cycle in premenopausal women, shifting alongside estrogen and progesterone (Effect of the menstrual cycle on serum DAO, 2012). Because estrogen fluctuates erratically during perimenopause, the body's histamine-clearing capacity may rise and fall less predictably — which is exactly why supporting the body's natural DAO activity becomes a topic of interest during this stage of life.*
The seesaw, in one line
Higher or erratically spiking estrogen → less DAO activity → histamine clears more slowly. Supplemental DAO is one way to help support the body's natural histamine-breakdown process in the gut.*What's Inside OmneDiem® Menopause Complete with DAO Plus?
Menopause Complete with DAO Plus is a multi-action formula built around DAO and paired with botanicals and a nootropic chosen to support women through the menopausal transition. Here's what each ingredient is included to support women during
| Ingredient | What is included to support* |
|---|---|
| Diamine Oxidase (DAO), 15,000 HDU | Supplies the DAO enzyme to support the body's natural breakdown of dietary histamine in the digestive tract* |
| Estro8PN® hops extract (8-prenylnaringenin) | A hops-derived phytoestrogen studied for supporting comfort during the menopausal transition* |
| Flaxseed extract (lignans) | Plant lignans that help support the body's natural hormone metabolism* |
| Black cohosh | A botanical traditionally used to support a sense of comfort and a healthy mood during menopause* |
| Citicoline | Supports focus, memory, and mental clarity* |
On the botanicals: a randomized, double-blind, placebo-controlled pilot study of a standardized hop extract (the source of 8-prenylnaringenin) explored its use for menopausal comfort (Erkkola et al., 2010), and 8-prenylnaringenin is recognized as one of the most potent plant phytoestrogens studied to date (&Štulíková et al., 2018). Results across botanical menopause studies can be mixed, which is why these ingredients are positioned to support the body rather than to treat any condition.*
How Menopause Complete Supports the Body During the Menopausal Transition
Rather than targeting one thing, the formula is designed to support three areas at once: the body's natural histamine metabolism (via DAO), hormonal balance during the menopausal transition (via hops, flax lignans, and black cohosh), and everyday mental clarity (via citicoline). It's taken daily, and many people take it before high-histamine foods or beverages to help support DAO activity where dietary histamine is processed.*

How to Choose a DAO Supplement for the Menopausal Transition
If you're looking specifically for DAO enzyme support, OmneDiem's DAO supplements range from single-enzyme Histamine Digest® formulas to the multi-action Menopause Complete. Look for a standardized HDU amount, a designed-release delivery that activates in the small intestine, and a clean label. If hormonal support and mental clarity are also priorities during this life stage, the all-in-one Menopause Complete may be the most convenient fit.*
FAQ: Menopause, Histamine & DAO
Can menopause affect histamine and DAO?
Research describes a relationship between estrogen and the histamine-clearing enzyme DAO: estrogen may down-regulate DAO activity, and DAO levels shift alongside hormones across the menstrual cycle (female sex hormones & DAO; menstrual cycle & serum DAO, 2012). During the menopausal transition, when estrogen fluctuates, the body's natural histamine metabolism may be affected. This is educational information, not a diagnosis.*
What does the DAO in Menopause Complete do?
It supplies diamine oxidase (DAO) to support the body's natural breakdown of dietary histamine in the digestive tract.* It is not intended to diagnose, treat, cure, or prevent histamine intolerance or any other condition.
What is Estro8PN®, and is it the same as estrogen?
Estro8PN® is a standardized hops extract that provides 8-prenylnaringenin, a plant phytoestrogen studied for supporting comfort during the menopausal transition (8-PN review, 2018). It is a botanical compound, not a hormone medication, and is included to support the body during this natural life stage.*
Can I take Menopause Complete with my other supplements or medications?
Always talk with your healthcare provider before starting any new dietary supplement, particularly if you are pregnant, nursing, taking medications (including hormone therapy), or managing a health condition.*
Is this a hormone replacement therapy (HRT)?
No. Menopause Complete is a dietary supplement formulated to support the body's natural processes during the menopausal transition. It is not a drug, not HRT, and is not intended to diagnose, treat, cure, or prevent any disease.*
