How to Boost the Immune System With Supplements

Immune System

Stop Being Sick

Most people have heard the term “immune system“, but how many actually know how it works?

Your immune system is actually a group of particular cells, mostly white blood cells. These cells are made in certain organs to protect you from bacteria, viruses, toxins and any other pathogens that may cause you harm.

We instinctively protect ourselves from dangers that we can see (fight or flight). However, there are threats that we can’t see and don’t know are there. Our body has to do the work to protect us.

Sometimes, like in the case of Covid-19, a pathogen can evolve faster than the immune system of the general public. This allows it to spread quickly, essentially unchecked.

However, illnesses that we have had for a long time, such as colds and influenza, should be able to be fought off by most healthy people.

In order to be able to fight them off with minimal or no symptoms, a healthy immune system is required.

What is the Immune System?

There are two different parts to each person’s immune system.

The first part is available and functional the moment we are born. It is required to keep us alive when our body has no idea what exists in our new environment.

The second part adapts to our environment, making it easier to survive things we have already been exposed to.

These two parts, the innate and adaptive immune systems, work together in unison to protect us from pathogens.

The Innate Immune System

The innate immune system is the half that we are born with and protects us immediately after we are born. It does its job without any outside influence.

The innate immune system includes cells called phagocytes (Greek, phagein, “to eat” and cyte, “cell“). These cells surround foreign particles, dead or dying cells, bacteria, etc. Once the invader has been surrounded by the cell, the cell proceeds to break it down and keep it from spreading. They are like portable jail cells to catch things that hurt us.

The most common phagocyte in the human body is the neutrophil. Neutrophils are a type of white blood cell. They make up 55 to 70 percent of the white blood cell count in a person.

Blood cellsBlood cells

Our blood flows to every part of us, and pathogens inevitably end up in our blood. So, it makes sense that our defence mechanism is a part of our circulatory system.

Phagocytes are naturally distributed in our bodies. They usually increase in number when we have problems, like infections. When we have a problem, our bodies do their best to contain and eliminate the threat.

The Adaptive Immune System

The adaptive (or acquired) immune system is more refined and specialized than the innate immune system. The innate immune system takes a generalized inherited pattern and protects against the problems that have been around for centuries. Our bodies have imprinted them into our DNA to keep us safe.

The adaptive immune system is constantly evolving and changing to protect us against pathogens that are new to us.

Viruses and bacteria evolve, just like any other living thing. As they evolve (each at a different rate), reinfection of that pathogen is possible. This happens because it isn’t the same one that our body already knows how to fight. We see this every year with the flu.


The way we learn to fight pathogenic infection is with antibodies. Antibodies are large “Y-shaped” proteins that are produced to fit a very specific problem. They are like a key. Each antibody can only work against the problem it was created for.

Antibodies, also known as immunoglobulins, are mostly produced by plasma cells, which is what is left over after red blood cells, white blood cells and platelets are removed from the blood. It is the suspension fluid that carries everything that our bodies need to where they need it.

When we come into contact with a pathogen, our body immediately starts working to build an antibody that “fits”. The antibody for that pathogen then gets circulated in our bloodstream and attaches itself to the pathogen wherever it is found.

The antibody attached to a cell “marks” the cell so other cells know it should be destroyed. Once marked, the innate immune system goes to work and destroys the cells the same way it does with any other infection.

Where the antibodies attach themselves is also important. Antibodies will bind to the areas on a foreign particle that makes it infectious. They will do their best to remove the ability to “dock” to other cells.

Once our body learns the specific antibody for a pathogen, it remembers it for the future.

What Makes These Cells?

There are areas of the body that make the cells we need for our immune system to work.

The following are the parts that need to work well for our immune system to protect us effectively:

  • Tonsils – located at the back of the throat, two oval-shaped masses.
  • Lymph nodes – located in various locations throughout the body, between 500-600 small bean-shaped organs.
  • Lymphatic vessels – similar to veins, carry lymph throughout the body, delivering oxygen and white blood cells and removing carbon dioxide.
  • Bone marrow – located in the center of bones, soft and spongy tissue.
  • Adenoids – located at the back of the nasal cavity, two glands.
  • Spleen – located in the abdominal cavity, fist-sized organ.
  • Thymus – located behind the breastbone, in front of the trachea, two lobes.

How Do I Improve My Immune System?

We have learned quite a bit about what our immune system does and how it does it.

Let’s look at how to boost the immune system with supplements.

Yes, we can eat better to have the same effect, but with a varying diet, it is usually not as effective as finding a way to consistently get the vitamins, minerals and other useful ingredients that you would get in a daily supplement.

It also takes away thinking about what is in your food if you already have what you need.

Staying Strong

Before we get to the supplements, you should know that doing the following will drastically improve your immune system:

  • eating healthy
  • exercising
  • eliminating foods to which you are:
    • allergic
    • sensitive
    • intolerant

Allergies trigger the immune system to handle what you are eating or drinking. This will leave you open to infection from something much worse.

Sensitivities and intolerance will hinder the digestive system. This will make it difficult to absorb the vitamins and minerals that would make your immune system stronger.

It is highly recommended to have an allergy test that also shows intolerance and sensitivity done as soon as possible. You should adapt your diet to eliminate those items.


There are herbs, vitamins and minerals used to treat common illnesses, such as colds and flu. Vitamin C is everyone’s first thought.

However, there are quite a few that help in different ways, including the following:

  • Selenium – an antioxidant that is proven to reduce inflammation and enhance immunity.
  • Echinacea – an herb that increases the number of white blood cells produced.
  • Garlic – antiseptic, antibacterial, and anti-fungal, has been known to help resist or destroy viruses and fight infection.
  • Beta-glucan – a polysaccharide (a molecule made up of sugar molecules) that has been known to improve immunity and help to prevent or fight diseases, such as cancer.
  • Spirulina – algae that promote antibody production, warding off infection and chronic illness, such as cancer.
  • Vitamin D – essential to the processes performed by the bone marrow. Required for a healthy immune system.
  • Vitamin C – essential for many processes in both the innate and adaptive immune systems, supports cellular function throughout the body.
  • Calcium – proven to be required for proper immune function. Deficiency of calcium can lead to increased viral and bacterial infection.

Most brands release many, single-ingredient supplements that take a Ph.D. to combine for the effects you want.

  1. Wow, such a splendid explanation of the immune system! I take all of the supplements you mention, except Echinacea and Beta-glucan.
    I only have Echinacea in the winter and I had never heard of Beta-glucan before!

    Like you explained a healthy lifestyle is equally important to taking supplements. For me that not only includes having the right food and excercises, but also have an eye for the environment. Trying to avoid pollution as much as I can.

    Thanks so much for your explanation!

    1. Hello Hannie,
