Histamine is a naturally occurring compound in your body, with a pivotal role in various physiological processes. It's a small molecule that plays a significant role in immune responses, stomach acid production, and neurotransmission. While histamine is essential for several bodily functions, an excess of it can lead to a range of uncomfortable symptoms. In this article, we will explore what histamine is, the symptoms of excess histamine, common triggers, and the enzymes responsible for metabolizing histamine.
What Is Histamine?
Histamine, chemically known as 2-(4-imidazolyl)ethylamine, is a neurotransmitter and a biogenic amine. It is synthesized from the amino acid histidine through a series of enzymatic reactions. Once produced, histamine is stored in specialized cells called mast cells and basophils, primarily in tissues that are in direct contact with the external environment, such as the skin, respiratory tract, and gastrointestinal tract.
Symptoms of Excess Histamine
Histamine plays a vital role in your immune system, helping to defend your body against pathogens. However, excessive histamine levels can lead to a range of unpleasant symptoms. This condition is known as histamine intolerance, and its symptoms can mimic allergies or other health issues. Common symptoms of excess histamine include
Skin Issues: Itching, hives, redness, and eczema are frequent skin reactions to excess histamine. Histamine can cause blood vessels to dilate, leading to these visible skin changes
Gastrointestinal Problems: Excess histamine can affect your stomach and intestines, causing symptoms like abdominal pain, bloating, diarrhea, and nausea.
Respiratory Symptoms: Histamine can constrict airways and trigger symptoms like sneezing, congestion, and wheezing, which are often associated with allergies
Headaches and Migraines: Histamine is a potent vasodilator, meaning it can expand blood vessels in the brain and lead to headaches or migraines.
Cardiovascular Symptoms: Some people may experience low blood pressure and an increased heart rate due to histamine-induced blood vessel dilation
Fatigue: Histamine intolerance can also lead to fatigue and a general feeling of malaise.
Common Triggers of Histamine:
Understanding what triggers excess histamine is crucial for managing histamine intolerance. Several factors can contribute to elevated histamine levels in the body.
Diet: Certain foods are high in histamine or trigger its release. These include aged cheeses, fermented foods, alcohol, and processed or smoked meats
Allergies: Allergic reactions can release large amounts of histamine in response to allergens like pollen, dust mites, or pet dander.
Gut Health: An imbalance of gut bacteria can impair the breakdown of histamine in the digestive tract, leading to its accumulation
Medications: Some medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) and certain antacids, can interfere with histamine metabolism
Stress: Stress can stimulate the release of histamine, exacerbating symptoms in individuals with histamine intolerance.
Enzymes that Metabolize Histamine:
In your body, histamine levels are carefully regulated by enzymes that break it down and convert it into inactive metabolites. Two key enzymes involved in histamine metabolism are:
Diamine Oxidase (DAO): This enzyme is primarily responsible for breaking down histamine in the digestive tract. It's produced by the cells lining your gut and helps prevent histamine from being absorbed into the bloodstream.
Histamine N-Methyltransferase (HNMT): HNMT is found in various tissues throughout the body and plays a role in metabolizing histamine in the brain and other organs. It helps regulate histamine levels in the central nervous system.
When these enzymes are functioning correctly, they help maintain a balance of histamine in your body. However, genetic factors, medications, or gut health issues can impair the activity of these enzymes, contributing to histamine intolerance.
Our new histamine complex uses a variety of ingredients to not only reduce the effects of histamine but also help your body metabolise it more efficiently. Including:
Creatine Monohydrate - Enhancing Histamine Metabolism and Energy Production
Creatine monohydrate indirectly promotes histamine metabolism by supporting the activity of histamine-metabolizing enzymes, such as diamine oxidase (DAO) and histamine-N-methyltransferase (HNMT). By facilitating the breakdown of histamine, creatine reduces its accumulation and helps alleviate histamine intolerance symptoms. Additionally, creatine plays a vital role in cellular energy production, ensuring optimal function and efficiency in histamine metabolism.
Organic Acerola: Natural Vitamin C - Antioxidant Defense and Histamine Modulation
Acerola is a rich source of natural vitamin C which is a potent antioxidant. Vitamin C protects against histamine-induced oxidative stress, which can exacerbate histamine intolerance symptoms. By neutralizing free radicals and reducing oxidative damage, vitamin C helps maintain a balanced histamine response. Furthermore, vitamin C exhibits anti-inflammatory properties and supports immune function, contributing to a well-regulated histamine system.
L-Theanine - Calming Inflammation and Modulating Histamine Release
L-theanine, derived from green tea, exerts anti-inflammatory effects by inhibiting the activation of pro-inflammatory signaling molecules, such as nuclear factor-kappa B (NF-κB). By reducing inflammation, L-theanine helps modulate histamine release and mitigate histamine-related discomfort. Moreover, L-theanine promotes relaxation by enhancing alpha brain wave activity, which can reduce stress-induced histamine release.
Bromelain - Digestive Support and Histamine Breakdown
Bromelain, a proteolytic enzyme found in pineapple, aids in the digestion of proteins, including histamine-rich foods. By facilitating protein breakdown, bromelain supports proper digestion and minimizes the absorption of intact histamine molecules. This digestive support helps reduce histamine accumulation in the body and alleviates digestive symptoms associated with histamine intolerance. Bromelain has also been shown to inhibit the production of pro-inflammatory cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). By reducing inflammation, bromelain may indirectly decrease the release or synthesis of histamine in certain immune cells.
Boswellia - Anti-inflammatory Action and Histamine Balance
Boswellia possesses potent anti-inflammatory properties due to its active components, such as boswellic acids. By inhibiting the activity of pro-inflammatory enzymes, including 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2), boswellia helps reduce histamine-induced inflammation and promotes a balanced histamine response. This anti-inflammatory action contributes to overall histamine tolerance and alleviation of associated symptoms.
Copper - The Central Atom of Histamine Metabolism Enzymes
Minerals play an important role in histamine balance and copper is no exception. Copper is an essential cofactor for DAO, the primary enzyme responsible for breaking down histamine in the gut. Adequate copper levels ensure proper DAO activity, facilitating efficient histamine metabolism and preventing its accumulation.
Vitamin B6 - Enzyme Co-Factor in Histamine Clearance
Vitamin B6, also known as pyridoxine or P5P, plays a crucial role in the metabolism of histamine. It is a cofactor in the production of enzymes that metabolise histamine, further supporting its regulation. While vitamin B6 may not directly lower histamine levels, its role in histamine metabolism suggests that it can help alleviate the effects of histamine-related conditions, such as allergies or histamine intolerance.
Bifidobacterium infantis and Bifidobacterium longum - Gut Microbiota Support for Improved Histamine Tolerance
Bifidobacterium infantis and Bifidobacterium longum, two beneficial probiotic strains, play a crucial role in supporting a healthy gut microbiota. By promoting a balanced microbial environment, these strains help optimize digestion and reduce histamine production in the gut. Furthermore these two specific strains have been to suppress allergic type symptoms and decrease histamine levels.
