Science & Formula
15 Years of Spanish Research - The scientists who created ProDAOX™️ spent 15 years perfecting the extraction process that preserves DAO's fragile enzymatic activity-work now protected by 96 patents.
Acid Safe Delivery System - Unlike competitors whose DAO enzymes get destroyed by stomach acid before they reach your small intestine, our coating delivers the full dose where histamine breakdown actually happens.
30,000 Histamine Degrading Units - 3rd party lab certified that each tablet delivers 30,000 HDUs of active enzyme
Nitrogen-Sealed Freshness - DAO enzymes degrade when exposed to oxygen, pH, and moisture, so we individually blister-pack each tablet in nitrogen to guarantee potency until the moment you take it.
Thoughtfully Designed For Maximum Benefits
Here's inner details that make us better than the rest
DAO is a “brush border” enzyme your gut uses to metabolize histamine from food in the digestive tract. Unlike plant-based imitators, our DAO is derived from porcine kidney extract, which is the gold standard for matching the human body’s natural histamine-degrading mechanisms. We utilize a patented extraction process refined over 15 years of research in Spain. This process ensures that you receive a highly bioactive form of the enzyme capable of neutralizing histamine from food immediately upon contact in your gut.
Most DAO supplements lose their potency on the shelf or in the bottle. ProDAOX™️ is stabilized to maintain a massive 30,000+ HDU (Histamine Degrading Units) per dose. This high concentration is critical because it ensures there is enough enzyme present to overwhelm and dismantle the histamine content of a full meal, preventing it from crossing into your bloodstream and triggering a reaction.
This delivery technology is the most vital component of the formula. The enteric coating protects this fragile enzyme through your stomach acid, releasing it in your small intestine where it intercepts histamine before absorption. This ensures 100% of the active enzyme is released exactly where it is needed to intercept histamine triggers. That is why many people notice results with their very first tablet—not because HistaHarmony is "stronger," but because the enzyme actually arrives intact and active where it needs to work.

How to Use HistaHarmony
For food-related histamine reactions
Take 1 capsule 20 minutes before eating histamine-rich foods.
If you’re not seeing results with this method, experiment with taking HistaHarmony™at different times of the day.
For gut and full-body histamine support:
Take 1 capsule at least 30 minutes away from meals or on an empty stomach when you usually experience histamine-related symptoms. For example, if you get flushed at night, take HistaHarmony™ before bedtime.
If your baseline histamine levels are already running high, you may experience more symptom relief and improved histamine tolerance by taking DAO away from food.

FAQs
HistaHarmony™ is for anyone experiencing reactions to high histamine foods or histamine intolerance symptoms.
Additionally, if you have any of the following, you may also want to consider DAO supplementation:
- Mast Cell Activation Syndrome (MCAS)
- Gut Inflammation
- Bowel Issues
- Gut InfectionsMold Toxicity
- Genetic variants for DAO (ABP1/AOC1 genes)
Depending on your overall histamine load, it could take several days to a few weeks to notice changes.
If you don’t notice results after a week or two, try changing the timing. For example, if you’ve been taking HistaHarmony™with meals, try taking it on an empty stomach (like before bed).
If the histamine bucket is overflowing, a 30-day low-histamine diet can often be a game-changer for many people, and enough to make a difference. In the case of Mast Cell Activation Syndrome (MCAS), however, you may need to go longer (up to 6 months).
When combined with DAO supplementation, your results on a low-histamine diet will likely improve even more. Not only are you emptying the histamine bucket, but you’re also “patching” any holes.
Keep in mind that long-term, restrictive diets can lead to nutrient deficiencies and make gut issues worse if we are not careful. The goal is always to expand the diet. Plus, eating plenty of colorful veggies and fruits helps feed friendly gut microflora and butyrate producers!
No, none of Healthy Guts products contain any Gluten, Dairy, Soy, Sugar, or GMOs!
HistaHarmony™ (and most DAO supplements) are derived from animal products. Ours is from porcine kidney extract (pork). So if you have a pork allergy or sensitivity, or avoid animal products for any reason, this product may not be right for you.
