How to strengthen your immune system ?

In these difficult times of forced confinement in the face of a virus against which we have no weapon, all attention is legitimately focused on the roles of our immune system in preventing viral attacks. Covid-19, caused by the Coronavirus, is a new disease of which no one really knows the origin, and even less the treatment. Strengthening your immune system then becomes a priority in the face of such danger., the only solution we all have to get through this unprecedented and planetary health crisis. To prevent or to cure, know how to strengthen your natural defenses must become as spontaneous a gesture as washing your hands or wearing a protective mask. In this article, we offer you an overview of our immunity, as well as our best advice to strengthen it.

How the Immune System Works

innate immunity

Innate immunity is made up of all the defenses we have to fight immediately against viruses, toxins and infections. We have in fact different barriers that are intended to defend us in real time. These are the skin, the digestive system and the respiratory system, which can block the entry of pathogens into the body. Also, this innate immune system is made up of the famous white blood cells (leukocytes), granulocytes, NK cells and phagocytes, which are involved in the defense of the body, the destruction of infectious agents and which stimulate the immune response.

acquired immunity

Acquired, or adaptive, immunity is that which is obtained, for example, by vaccination or when one has already contracted a disease. The body is exposed to a pathogen, and a whole system is set up to recognize it and destroy it in case of new exposure. Immunity cells are T and B lymphocytes:

  • T cells recognize an unhealthy cell, cause it to die, and once the infection is eradicated, the lymphocyte dies.

  • B cells produce antibodies.

The basics of immunity

Knowing how to boost your immunity is the first line of defense against disease. To do this, follow these simple precautions.

Have a healthy lifestyle

Not smoking, eating a balanced diet, sleeping well, reducing stress and having regular physical activity are habits to adopt over the long term to stay healthy.

lose weight

People who are overweight are more prone to chronic disease and inflammation, that reduce the ability of the immune system to defend itself. And as proof, patients with diabetes and cardiovascular problems are clearly more exposed to complications induced by Covid-19. Largely because their immunity was previously reduced by their state of health.

Chronic Inflammation Kills Us

Inflammation is a problem when it becomes chronic. And it becomes chronic when you eat badly, when you don’t move enough, when you stress too much and when you sleep badly. Dietary imbalances are responsible for almost the majority of chronic inflammation, and thus promote the appearance of diseases such as diabetes, venous disorders, heart pathologies, hepatic steatosis, etc. The immune system is in this case clearly weakened and disorganized, which leads to a reduced defense, a higher risk of contracting other diseases, including Covid-19, or of succumbing to their complications.

Food supplements: the special forces of immunity

  • It supports the various cellular functions of the innate and acquired immune system.

  • It strengthens the epithelial barrier of the skin against pathogens and reduces oxidative stress directly in our cells.

  • It is widely present in immune cells where it acts as an antimicrobial agent.

  • It regulates the production of T and B lymphocytes.

  • It reduces the severity of respiratory and systemic infections.

Vitamin D

Vitamin D is a fat-soluble vitamin that increases the activity of monocytes and macrophages (white blood cells), which reduces inflammation and improves the immune response. A randomized study of over 11,000 people found that vitamin D supplementation reduced the risk of respiratory infections in people with deficiency, and that it reduced the risk of complications in people who were not deficient.

By supporting the various functions of the body, a multi-vitamin is the most affordable and simple solution to provide the vitamins of immunity in a single product. Prefer a complex that contains vitamin C, vitamin D, vitamins of group B, as well as minerals and, if possible, antioxidants. Antioxidants reduce the damage caused by oxidative stress, which is one more precaution against viral diseases and epidemics.

Aminotherapy and whey


Glutamine is the amino acid of immunity. It is the primary fuel for leukocytes (white blood cells) and our intestinal cells, which are also intimately involved in protecting our body against external aggressions. For these reasons, the medical community uses glutamine to treat immunocompromised patients, as well as people with severe burns, for example. Glutamine supplementation reduces risk of infection and recovery time in people who are already ill.

whey protein and lactoferrin

Lactoferrin is a glycoprotein that binds to iron, preventing its uncontrolled accumulation in the body. In a study published in 2012 by Pr Legrand at the University of Lille, we can read: “Lactoferrin (Lf) belongs to the family of antimicrobial molecules constituting the main line of defense of invertebrates. In humans, their roles go far beyond antimicrobial properties. In effect, Lf is involved in innate and acquired immunity where its modulating effects provide the host with protection against microbes and the harmful consequences of inflammation”. To strengthen your immune system, lactoferrin supplementation is of proven effectiveness. But where to find it? Simply in whey concentrate, where it occurs naturally in large quantities. Whey protein is a supplement that supports the osteo-muscular system, but its effects on health have not finished surprising us.

Omega 3

As we have seen earlier in this article, chronic inflammation prevents our body from defending itself against infectious agents. And to reduce this inflammation that weakens our immune system, nothing more effective than Omega 3 of good quality, rich in EPA and DHA. Omega 3 are effect fatty acids that balance prostaglandin metabolism and inflammation in our body. A study conducted by Dr. Fenton at the University of Michigan and published in the Journal of Leukocyte Biology indicates that EPA and DHA prevent inflammation-induced diseases, but that they also increase the activity of B cellswhich naturally increases the synthesis of antibodies.

The Best Anti-Stress Supplements

Stress and lack of sleep are aggravating factors of chronic inflammation. And right now, we are all stressed by events, and more and more people are struggling to sleep and relax. To improve well-being, sleep and the body’s response to stress, a supplement can provide you with the greatest comfort: ZMA. Composed of zinc, magnesium and vitamin B6, ZMA strengthens the deep (restorative) sleep phase, reduces stress and improves mood. Try the experiment and supplement yourself with ZMA for a few weeks, you will quickly notice that you sleep better, that you are more resistant to stress and that you have more energy.
ZMA also boosts the immune system thanks to the action of zinc, a mineral involved in the development and functions of innate immune cells. In addition, zinc deficiency negatively affects the growth and functions of T and B cells.

To conclude

Strengthening your immune system remains today the best way to reduce the risk of infection and the risk of complications, and not only in the event of an epidemic! Taking care of yourself and your natural defenses is the best method of prevention. Stay strong, and stay home!
