The immune system is a network of systems, not a single unit, that work together within your body to protect you from invaders such as bacteria, viruses, fungi, and toxins.

It needs balance and harmony to function well.

Let´s discuss how you can improve your immune system with some of the best immune system boosters.

Immune system an in-depth look

Innate immune system

The innate immune system is the first to respond. However, its response is not specific. The skin, the eye´s cornea, the mucous membrane lining, the respiratory system, the gastrointestinal tract, genitourinary tracts, and blood-brain barriers (endothelial cells) all create physical barriers to help protect your body. The innate immune system is inherited.

The adaptive (acquired) immune system

The adaptive immune system works together with the innate system and makes antibodies, a form of proteins, to protect your body from (antigens) invaders. Its immune response is pathogen and antigen-specific therefore, its response is more complex.

Unlike the prompt response in the innate immune response, the adaptive response takes a long time (can take up to several days) between exposure and maximal response. Exposure to an invader that successfully entered the system leads to immunological memory.

Sometimes the body´s immune system mistakenly fights itself, such as in autoimmune diseases (Lupus and MS). The opposite is also true sometimes, the body`s immune system is not fit enough to fight off an attack.

Vaccines help your memory cells store data on antigens they encountered before and can provide long-term immunity, as in the case of measles, once vaccinated, you can be protected from measles your whole life.

Where can the immune system be found?

The cells of both parts of the immune system are made in different organs of the body. But here are some locations.


Adenoids are two glands found at the back of the nasal passage (in children). They help fight off germs that you breathe in.

Bone marrow

Bone marrow is the soft, spongy tissue found in bone cavities. It is where B-cells are selected, developed, and matured.

Lymph nodes

The lymph nodes are small organs with a bean-like shape, they form clusters around the body, and connect via the lymphatic vessels. Prominent areas are under the arms, neck, groin area, and behind your ears. Filter out potentially dangerous substances.

Lymphatic vessels

Lymphatic vessels are a network of channels that are all over the body and carry lymphocytes to the lymphoid organs and bloodstream. The spleen, thymus, and tonsils are lymphatic organs. Lymphatic vessels maintain fluid balance and immune defense.

Peyer patches

Peyer patches are lymphoid follicles in the mucus membrane in the small intestine. Peyer patches play an important role in immune surveillance recognition and destroy invaders.


The spleen is a fist-sized organ found in the abdominal cavity (upper left). It´s part of the body´s lymphatic system. The spleen is involved in the body´s immune response and recycling old blood cells (filters blood).


The thymus is two lobes that join in front of the windpipe (trachea) behind the breast bone. The thymus helps mature T cells (white blood cells responsible for fighting infections).


The tonsils are two oval masses in the back of the throat. The tonsils help fight infections.

How can you improve your immune system?

You are aware that the immune system functions to defend you against disease-causing microorganisms. But sometimes, it fails because a germ successfully enters your system and makes you sick.

Healthy ways to strengthen your immune system include:

  • make healthy lifestyle changes (stop smoking, avoid illicit drug use, limit/reduce alcohol)
  • eat more fruits and vegetables daily
  • maintain a healthy weight
  • exercise regularly
  • get enough sleep
  • wash hands frequently and correctly
  • make sure foods/meat are thoroughly cooked
  • put healthy stress-reduction strategies in place to minimize stress

The body is constantly generating immune cells. A healthy immune system needs good, regular nourishment. If you discover that your diet is not providing you with all your nutritional needs or if you don´t like to eat vegetables (try to find creative ways to prepare vegetables), taking a supplement for a little while may give your immune system the boost that it needs.

The immune system is a network of systems working together to help your body fight diseases. A healthy immune system needs good, regular nourishment. Lifestyle changes such as a healthy diet, exercise, avoiding cigarette smoking, drinking too much alcohol, and avoiding illicit drug use.

Sometimes your immune response is powerful, but other times due to several circumstances (not getting sufficient nutrients from your diet), your body may need a boost, and supplements may help.

  1. Being healthy and sustaining good health is a part of happy living. Choosing and practicing a healthy lifestyle as daily habits can help.

    A healthy and excellent immunity defends your body from fighting against the virus and keeping you in good health.

    We are through a pandemic, and still, new variants are being reported. However, the mask is not completely covering our nose and mouth. While eating nutritious food is the core of health, leaving essential elements or lack of digestion or/and absorption can cause deficiencies.

    The supplements here can help to maintain your health. It’s beneficial to find supplements for immune health improvement and support.

    The succinct description of the immune system offers vital knowledge.

    We use turmeric in our everyday cooking.

    Of the supplements described, how much and when should I take them?

    1. Thank you, Anusuya, for your valuable input. You are right. The pandemic taught us the importance of having a strong and healthy immune system. 

      There are new diseases on the horizon, and we do not know what they will bring with them. It is just wise to support our immune systems to fight off any attack, both old and new.

      The supplements are one a day, preferably in the morning before you start your day. For more information, go here https://www.naturalhealthsourc
