Recommended Supplements

Evidence-based picks
🧬
DAO Enzyme (Diamine Oxidase)
The most targeted supplement for histamine intolerance. DAO is the enzyme responsible for breaking down histamine in the gut. Taking it with meals can significantly reduce histamine reactions to food.
Typical dose: 1–2 capsules taken 15 min before histamine-containing meals

🍎
Quercetin
A natural mast cell stabilizer — it inhibits the release of histamine from mast cells before it even enters circulation. One of the most useful supplements for histamine intolerance management.
Typical dose: 500–1,000mg daily with food

🍊
Vitamin C
Vitamin C directly supports DAO enzyme activity and helps break down histamine. It also acts as a natural antihistamine by competing for the same receptor sites.
Typical dose: 500–1,000mg buffered Vitamin C daily

🦠
Probiotics (Histamine-Safe Strains)
Not all probiotics are safe for histamine intolerance — many strains produce histamine. Look for histamine-degrading strains: Lactobacillus rhamnosus, Bifidobacterium longum, and B. infantis.
Typical dose: 10–50 billion CFU daily of histamine-safe strains only

🌿
Magnesium
Magnesium is a cofactor required for DAO enzyme activity. Many people with histamine intolerance are also magnesium deficient, which worsens their ability to break down histamine.
Typical dose: 300–400mg magnesium glycinate daily
View Recommended Products
🛡️
Zinc + Copper
Zinc is a critical cofactor for DAO enzyme function. Deficiency significantly impairs histamine metabolism. Always balance with a small amount of copper to avoid depletion.
Typical dose: 15–25mg zinc with 1–2mg copper daily
