DAO Enzyme for Histamine Food Intolerance

Expand your dietary freedom and increase your ability to digest histamine-producing foods with HistaHarmony by Healthy Gut. 

This premium oral supplement supplies high-patency, multi-patent Diamine Oxidase (DAO) to directly support the natural breakdown of food-derived histamine in your digestive tract. Enhanced with a highly bioavailable Quercetin Phytosome that absorbs up to twenty times better than standard quercetin, alongside dense bioflavonoids like Luteolin and Rutin, this non-habit-forming formula helps eliminate post-meal fatigue, temporary flushing, and digestive discomfort. 

Formulated in clean vegetable capsules and nitrogen-packed for maximum enzymatic freshness, it allows you to comfortably enjoy your favorite foods and beverages again.

  • Increases Your Ability to Digest Histamine-Producing Foods: Delivers high-patency, multi-patent Diamine Oxidase (DAO) derived from standardized porcine kidney extract to directly assist your body in breaking down food-derived histamine in the gut.
  • Eliminates Fatigue After Eating: Restores the critical enzymes needed to process complex meals, helping to prevent the sluggishness, heavy post-meal fatigue, and temporary difficulty concentrating or brain fog that often follow high-histamine dishes.
  • Manages Your Internal Histamine Baseline: Supports your immune system's natural chemistry by keeping your digestive histamine levels balanced, ensuring this vital chemical continues to support normal stomach acid and healthy sleep-wake cycles without overflowing.
  • Addresses one Root Cause of Food Sensitivities: Directly supports individuals whose digestive systems have trouble breaking down dietary compounds, offering an efficient solution when a restrictive low-histamine diet fails to solve the underlying enzyme deficiency.
  • Reduces Post-Meal Flushing and Discomfort: Targets and metabolizes excess dietary histamine right in the digestive tract, actively easing temporary face and neck flushing, unexpected dizziness, dry mouth, or a racing heart after eating.
  • Helps You Safely Expand Your Dietary Choices: Supplements your body's natural enzyme levels so you can reintroduce aged, fermented, or complex items, meaning you might comfortably enjoy a glass of wine or favorite healthy foods again.
  • Maximizes Flavonoid Absorption and Bioavailability: Features premium Quercetin Phytosome, a clinically advanced lipid-wrapped compound that absorbs up to twenty times better than standard quercetin to support normal cellular defense pathways.
  • Provides Advanced Antioxidant Enzyme Protection: Utilizes lipid-soluble Vitamin C as Ascorbyl Palmitate to act as a clean-label stabilizer, shielding the fragile DAO enzyme from rapid oxidation to ensure peak functional potency upon consumption.
  • Supplies Comprehensive Cellular and Tissue Support: Combines pure Luteolin and Rutin to offer exceptional antioxidant properties that neutralize free radicals, maintain normal cellular response mechanisms, and protect capillary integrity.
  • Guarantees High Product Potency and Longevity: Benefits from specialized manufacturing that uses oxygen-displacing nitrogen flushing inside the bottle, keeping the delicate botanical and enzyme compounds highly active and fresh until opened.
  • Clean Label Allergen-Free Delivery: Encapsulated strictly in plant-derived Hypromellose vegetable capsules with zero milk, egg, fish, shellfish, soy, wheat, gluten, peanuts, tree nuts, yeast, rice, or artificial additives.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
