What Are Allergies?


Allergies happen when a person’s immune system reacts negatively to a foreign compound that comes into contact with the body. Usually, such substances don’t cause the same reaction in most other people.


How Do Allergic Reactions Happen?


Antibodies are part of the immune system. When you have allergies, the immune system creates these antibodies to hunt down allergens, substances that aren’t ordinarily harmful to others.

The body creates an allergic immune response if you come into contact with these substances, and they can manifest as inflammation in your skin, airways, and even your digestive system.

How severe an allergy is depends on the person; not all are equal. For some, they may experience minor irritation, while others can experience potentially life-threatening anaphylaxis.


What Are the Common Allergens?


What Are the Common Allergens?


Here is a list of the most common allergens that could cause allergy symptoms.




Those who experience allergic immune responses after eating or even contact with certain food items have food allergies.

Like many other allergies, reactions to food allergies can be mild but also life-threatening. Some only experience hives, while others may also experience digestive reactions like nausea, diarrhea, and vomiting. The worst-case scenario is experiencing anaphylactic reactions after consuming food.

People can be allergic to any food, but the most common food allergens include seafood, dairy, soy, wheat, nuts, and eggs.




Allergens that you can inhale, most commonly dust, pollutants, pollen, and mold, can cause an allergic immune response in the form of respiratory inflammation. Inhaled allergens may cause allergic rhinitis. It may cause swelling of the sinuses and mucus production, resulting in the person becoming congested.

A more severe result of coming into contact with these allergens in the air is asthma, which, in the worst cases, can cause the airways to close off, preventing the person from breathing.




Certain types of medicine can be allergens for some people. Most commonly, people can experience allergies to NSAIDs like Ibuprofen and Naproxen, Antibiotics like Amoxicillin and Penicillin, and Aspirin, among others. Like most other types of allergies, the reactions to drugs can vary from mild to life-threatening.


Insect Bites or Stings


Some people experience allergic reactions to insect bites and/or stings. Those with this allergy may experience hives on the bite site and surrounding areas. However, it’s also known to cause anaphylaxis for some, requiring immediate medical attention.


What Is Anaphylaxis?


Anaphylaxis is the worst-case scenario when it comes to allergic reactions, including those to food and insect stings. This is a life-threatening emergency that needs immediate medical treatment as it may result in shock. Some of its symptoms include.

  • Losing consciousness
  • Experiencing a rapid drop in blood pressure
  • Experiencing lightheadedness
  • Having severe shortness of breath
  • Having hives
  • Having a weak but rapid pulse
  • Experiencing nausea and vomiting.


Getting to Know Chlorella as a Supplement


Chlorella is a popular superfood thanks to its rich nutrient profile and numerous health benefits. It’s a type of unicellular green algae that many people use as a food supplement. Chlorella is natively found in the freshwater bodies of Japan and Taiwan. Today, chlorella growing facilities are found in China, India, and the United States (Hawaii).

As a superfood, chlorella contains many nutrients. Here are some of them:

  • Protein: Chlorella contains complete proteins with all nine essential amino acids.
  • Antioxidants: Chlorella has many antioxidant ingredients, including chlorophyll, carotenoids, and antioxidant vitamins C and E
  • Chlorella Growth Factor: This is a unique nutritional complex in chlorella cells. It promotes rapid cell growth and healing, and it can help boost the immune system.

If you’re looking for chlorella supplements, it’s best to know the types you can find in the market today. Most manufacturers use either one of the two strains of chlorella – chlorella vulgaris and chlorella pyrenoidosa. While they both carry many different healthy compounds, most people prefer the pyrenoidosa strain thanks to its dense nutrient contents.

Usually, chlorella products are sold in different forms, namely chlorella powder, chlorella tablets, and chlorella liquid extracts.


Some Health Benefits of Chlorella

Benefits of Chlorella


Does chlorella reduce histamine? Can I use chlorella for food allergies or rhinitis?

When exposed to allergens, the body releases a substance called immunoglobulin E. This substance then triggers histamine release. The release of histamines results in the symptoms of allergic reactions, including hives, allergic rhinitis, asthma, and anaphylaxis.

Luckily, studies have found that chlorella as a supplement may help reduce inflammation caused by allergies. It does so by helping suppress the production of immunoglobulin E and impede the release of histamines. According to experts, this may be due to chlorella being rich in polysaccharides, which have properties that help ease allergies.

On top of this, chlorophyll, which chlorella is rich in, helps bind toxins and flush them out of the body. This detoxifies the body and may also help lower the risk of starting an allergic immune response chain. As such, you may use chlorella for seasonal allergies.

Studies have also suggested that antioxidants have similar effects.


Can You Take Chlorella for Eczema?


Can chlorella help eczema? Yes, chlorella has the potential to help those with eczema or atopic dermatitis. It does so potentially due to the anti-inflammatory properties brought by antioxidants in chlorella.

Additionally, an animal study has found that chlorella vulgaris supplementation has the potential to help with this skin condition. It does so by helping modulate immune responses in the body.


Frequently Asked Questions


Can You Be Allergic to Chlorella?


Can chlorella cause skin rash? Is chlorella high in histamine? Yes, a person may experience an allergic reaction to chlorella. Most chlorella allergy symptoms are minor, including skin rashes, but like many allergens, a small number of people may experience a severe reaction. Luckily, chlorella allergies are extremely rare, and this superfood is generally safe for consumption.


How Do You Calm Allergies Naturally?


There are many ways to help calm your allergies the natural way. Here are some tips:

  • Stay hydrated. If you’re dehydrated, your body releases more histamines. On top of that, the mucus membranes on your air passageways, like your sinuses and throat, are more susceptible to irritation from pollen and other airborne allergens.
  • If you have skin allergies, you can use a cold compress to help soothe irritated skin. You may also use natural anti-inflammatory healing ingredients such as aloe vera, coconut, and tea tree oil.
  • Taking apple cider vinegar may help with seasonal allergies. It does so since ACV helps boost immune function.

However, if you’re experiencing symptoms of anaphylaxis, you will have to seek immediate medical attention. If you have a history of severe allergic immune responses, it’s best to have an Epinephrine auto-injector handy as first aid.


What Supplement Is Good for Allergies?


What is the best natural antihistamine? There are numerous natural food items that have anti-allergy and antihistamine properties. Some items with the most research backing include stinging nettle, foods rich in flavonoids, and butterbur.

However, vitamin C has shown prominent antihistamine properties when it comes to dietary supplements. Other popular anti-allergy supplements include quercetin and probiotics.


Chlorella and Allergies


Medical antihistamines are the most popular way to alleviate allergic reactions immediately. However, proper nutrition may also help with allergy symptoms, especially if you experience chronic inflammation because of allergens.

There are many natural ways that can help mild allergic reactions, including chlorella supplementation. As a dietary supplement, this superfood manages to bring relief to mild chronic allergies.
