About Pure Encapsulations - DAO Enzyme

Pure Encapsulations DAO Enzyme provides diamine oxidase (DAO), the primary intestinal enzyme responsible for breaking down histamine from food. Formulated for individuals who may have reduced DAO activity, it supports the body's natural ability to metabolize dietary histamine in the gut. This product is particularly relevant for those who experience sensitivity after consuming histamine-rich foods like aged cheeses, fermented products, or wine.

Why It's Worth Considering: Pure Encapsulations uses a highly purified, porcine-derived DAO isolate in a clinically relevant dose, formulated without common allergens or unnecessary excipients, consistent with the brand's practitioner-grade standards.

Who Benefits

Best For

  • Adults seeking diamine oxidase enzyme support for histamine metabolism
  • Individuals maintaining comfort after consuming histamine-rich foods or wine
  • Practitioners protocols requiring DAO enzyme replenishment in sensitive patients
  • Those with low diamine oxidase activity looking to support dietary histamine breakdown

  • Active pancreatitis

Frequently Taken Together

Complete Gut
Probiotics
Enzymes break down food mechanically while probiotics optimize the microbiome. Together they address both aspects of digestion.

Gut Repair
L-Glutamine
Enzymes improve digestion while glutamine repairs the intestinal lining. The two-pronged approach to gut healing.
Thorne - L-Glutamine Powder
$67.99
Stomach Acid
Betaine HCl
Many people have LOW stomach acid (not high). Betaine HCl restores acid while enzymes handle the downstream breakdown.

Frequently Asked Questions

  • Take immediately before or with the first bites of your meal. Enzymes need to be in the stomach when food arrives. Taking them after eating is less effective. For best results, take with every substantial meal — especially meals high in fat, protein, or hard-to-digest foods.

  • They serve different functions. Enzymes physically break down food into absorbable nutrients. Probiotics are living bacteria that optimize the gut microbiome, produce vitamins, and support immune function. Many gut issues benefit from both — especially after age 40 when natural enzyme production declines.

  • No. Digestive enzymes do not cause your body to produce fewer of its own enzymes. They supplement what your body is already making (or under-making). You can stop taking them anytime without withdrawal or rebound. If your symptoms return after stopping, it means you still need the support — not that you've become dependent.
