Histamine Digest PureMax with DAOgest by Omne Diem contains Diamine Oxidase (DAO), the histamine neutralizing enzyme that helps to regulate optimal histamine levels in our body and promotes healthy digestive, nervous and immune system function.

What is Histamine?

Histamine is a chemical compound found in our body cells and performs various important functions of the body such as the digestive system, immune system, and nervous system function. 

  • Digestive system:   The optimal amount of histamine present in the gastrointestinal tract stimulates the parietal cells to produce the gastric acids required for digestion. 
  • Nervous System:    Histamine present in the central nervous system regulates various brain functions.
  • Immune system: Histamine also plays a significant role in our immune system. When our body discovers an invader (new cells), the immune cells make antibodies and spread throughout the body in order to fight against them. 

Our body should have adequate amounts of histamine, but if it is present in excess levels, it becomes intolerable and that leads to symptoms such as,

  • migraine, 
  • sneezing, 
  • itchy skin, 
  • bloating, 
  • constipation, 
  • stomach aches, 
  • digestive distress,  
  • asthma, 
  • difficult in breathing,
  • irregular heartbeat.

What is DAO? 

Diamine oxidase (DAO) is an enzyme your body produces to digest food that contains histamine. Diamine oxidase deficiency occurs when the body doesn't produce enough DAO.

Deficiency of DAO Causes: 

Most of these above symptoms are also caused due to deficiency of DAO. This supplement contains DAO, which reduces the symptoms caused by excessive histamine levels. 

With 6.4 mg of natural diamine oxidase per capsule delivers 30,000 HDU. Histamine Relief PureMax provides you with the highest potency of DAO supplements on the market. DAO helps to break down the histamine that enters your body through various foods & beverages in our regular diet such as pickles, and beverages.
