You might have heard ads that talked about products being “anti-histamine.” What’s it all about? This is a chemical compound that the body produces due to factors like allergies, inflammation, and injury. The big question is which amino acid histamine produces. This is important so you’ll know the best treatments to deal with the symptoms related to histamine. The human body contains 20 amino acids. This includes 9 that are obtained through food and 11 that the body produces naturally. Conditions like allergies and inflammation are common. Fun Fact: About 55% of the USA’s population has 1+ allergies. Meanwhile, inflammation is another common condition that some health experts believe cause many serious diseases.

Histamine contains one of the essential amino acids (EAAs) known as Histidine. This is one of the 9 essential amino acids (EAAs) that humans have to get from food and supplements. It differs from non-essential amino acids (NEAAs) that the body produces It’s important to get enough EAAs from different foods like beef, eggs, soybeans, and dairy. In fact, these are some foods that have all the EAAs and the right amount for a full day. The best way to deal with histamine is to know which amino acid it contains so you can treat it effectively with medicines.

What Is Histamine?

If you’ve surfed the net, watched TV, or listened to the radio you’ve probably heard of the term “antihistamine.” What’s it all about? The medicines known as antihistamines are used to deal with allergy symptoms.

Let’s get to the nitty-gritty of histamines. These are chemicals produced by the human immune system. These chemicals help the body to ditch unwanted stuff. In the case of this medicine, it’s allergies/allergens.

Histamines launch the body’s process that ditches the allergies from the skin or inside the body. This might cause symptoms like sneezing, itchiness, or ears but these are signs the medicines are working. It’s part of the body’s natural defense system.

If you have allergies then some triggers can seem harmless. That includes dust, pollen, and dander (from pets’ skin). However, the immune system thinks the stuff is a threat so the response is to get rid of the allergy-causing substances.

The body has good intentions. However, when it over-reacts this causes well-known allergy symptoms. That’s what antihistamines are all about. When you experience an allergy trigger the human immune system picks it up. It then causes a group of reactions to protect you.

The immune system first sends a signal of chemicals to different body parts. They include the mouth, nose, skin, gut, lungs, and blood. The message is to send out histamines that the body stores in something called “mast cells.”

So, when the histamines exit mast cells this helps to increase blood flow where the allergen is affecting the body. It results in inflammation. That results in the immune system’s other chemicals to start their repairs. Then histamines stop in areas in the body known as receptors.

The end result is your body deals with the allergens to get rid of them. They include itchy nose, watery eyes, and coughing throat.

Amino Acid Histamine: What Does It Have?

Histamine contains the amino acid histidine. This is one of the EAAs that humans have to get from food. Histidine is found in high-protein foods and some grains. This amino is “essential” because humans have to get it from food and supplements.

You can find histidine in almost all of the body’s cells. This is true of other amino acids so it’s not really a game-changer. This amino is related to many biological processes. For example, it helps to form a protective layer around nerve cells. It also helps the brain send signals to various body parts.

Histamine is also important for getting rid of dangerous stuff like heavy metals including mercury and copper. This allows the body to make red and white blood cells. Since the acid is involved in making histamine the amino also produces enzymes that are required for good digestion. This helps the immune system to respond to allergens.

There are also different kinds of histidine. For example, L-histidine is needed so the body can process several minerals like zinc, iron, and copper. It’s also needed to make different enzymes including antioxidants.

Some studies show that if you have low histidine levels this could cause various health issues. One example is researchers believe that this could result in a higher risk of serious diseases like rheumatoid arthritis. Studies show that ultra-low levels of histidine can cause mental issues like anxiety and depression.

Supplements might help some people. However, it can cause negative results for some people. Studies show that people with depression should not take histidine supplements

As always, it’s important to talk to your doctor before you start taking a new dietary supplement. He/She can inform you about whether or not you should take this particular amino. That’s because factors like medical conditions and medicines/supplements you’re already taking should be considered.

Foods with Histidine Amino Acids

1. Meat/Seafood

You can also get this amino acid in meats like beef, chicken, and pork. It’s good to eat different types of meat so you’ll be getting different aminos. In general, you should eat more chicken than red meat since it’s lower in saturated fat. However, it’s OK to eat some beef or pork from time to time.

Seafood is another good source of histidine. This includes fish, shrimp, crabs, oysters, and lobster. Fatty fish and shellfish are both good sources of omega-3 fatty acids. Fatty fish includes:

  • Tuna
  • Sardines
  • Herring
  • Trout
  • Mackerel

2. Vegetables

You can also get this amino acid in some veggies including potatoes, cauliflower, and mushrooms. While it might be tougher to find you can also get histidine from bamboo shoots, which are popular in Chinese cuisine.

3. Fruits


Good options include citrus fruits like oranges, tangerines, and grapefruit. You can also get the amino from other foods like cantaloupe and bananas. These are also “superfoods” that are chock-full of several vitamins, minerals, and antioxidants.

4. Beans/Peas

There’s some debate about whether or not these foods are healthy since they’re high in a protein called “lectins.” However, you can simply soak ones like kidney beans to reduce the lectin content.

5. Grains


You can also get this amino acid from some grains, including wheat, rice, and rye. The best sources are whole grains instead of processed ones. This will help to maximize the nutritional value you get. If you have a gluten allergy make sure to avoid wheat and rye.

6. Dairy

This is one of the complete proteins since it has all 9 EAAs including histidine. You can pick from different options like milk, cheese, and yogurt. Dairy is also high in nutrients like calcium and Vitamin D. Besides aminos dairy is also a good source of protein and is the amino acid histamine has.
