Increase immunity and fight off infection with these immune system supplements and vitamins that are proven to boost immune system health.
We are now in the second peak of the coronavirus pandemic, and the question that almost all of us want the answer to is how can we boost immunity and fight off infection better.
The good news is that the COVID-19 vaccines appear to be effective in preventing infection as CDC data has shown that 99.992% of fully vaccinated people have dodged COVID.
But as the top infectious disease expert in the US, Dr Anthony Fauci, stated, vaccination is not a one-and-done way to end the pandemic, and we may never get rid of the coronavirus entirely.
Public-health measures like wearing masks and social distancing are critically important ways to curb infections until we have sufficient herd immunity to end the contagion. A great deal of research has shown that healthy diets and nutrition are also important in boosting immunity.
But, you don’t need to be a nutritionist to know that our modern diets are deficient in many of the ingredients we require to boost immune system health and adaptive immunity – which provides long-lasting protection to those who have recovered from infections.
Although there is a lot we need to learn about how to boost immune system response to newer pathogens like the Sars-Cov-2 coronavirus, there is ample evidence to show that that certain nutritional supplements can increase immunity and improve our ability to recover faster.
7 Health Supplements To Increase Immunity
Here are some nutritional supplements that have been shown, in recent scientific studies, to increase immunity, provide a protective effect from respiratory infections, and help patients recover faster from illness.
The largest observational study of SARS-CoV-2 infection and dietary supplement use to date found that taking health supplements with multivitamins, Omega-3, probiotics, or Vitamin-D, may reduce the risk of testing positive for the COVID-19 coronavirus among women – but not in men.
“There is good evidence that if you have a low vitamin-D level, you have more of a propensity to get infected when there are infections around,” says Dr Fauci. The research also found that taking vitamin C, zinc, or garlic supplements did not increase immunity to infection.
Another study found that having healthy levels of Vitamin-D can reduce the risk for adverse clinical outcomes in patients with COVID-19 infection. Vitamin-D deficiency has also been linked to decreased lung function and an increased risk of respiratory diseases.
What this tells us is that healthy levels of the fat-soluble Vitamin-D, which is known to be important for immune system health, can increase immunity and may protect against respiratory illnesses like COVID-19.
2. Probiotic Foods
Probiotics are basically healthy bacteria that restore the balance of normal flora – the living microorganisms that we play host to inside our bodies.
In the last few years, many studies and clinical trials have found that an imbalance of microbes in the gut is linked to a number of health disorders, from mood and mental health to autism.
Probiotic foods – including fermented foods like yoghurt – are some of the best foods to eat to boost immune system health. They promote a healthy balance of gut bacteria and have been linked to a wide range of health benefits.
In fact, taking probiotic supplements has been shown to reduce markers of inflammation in the body and decrease depression, anxiety, and stress.
Probiotics can also help modulate immune system response and treat various diseases, especially viral infections. They have been shown to promote the production of natural antibodies in the body and decrease respiratory infections.
A recent study found that probiotic strains of Lactobacillus and Bifidobacterium can trap the COVID-19 virus and interfere in the virus binding to the host cell receptors.
3. Omega-3 Fatty Acids
Omega-3 fatty acids are healthy fats that are found in fish oil, flax seeds, and other food sources such as nuts. One of the most harmful effects of COVID-19 is the cytokine storm that causes inflammation.
Omega-3 fatty acids are known to decrease inflammation and improve immune system health. They also improve cardiovascular health, joint health, brain function, mental health, and have many other benefits.
In December 2020, nutrition experts from China advised that the intake of omega-3 fatty acids could reduce fatality rates in severe COVID-19 patients.
American researchers also published evidence showing that higher omega-3 blood levels may reduce the risk for death from COVID-19 infection.
Other studies have also found that very long-chain omega-3 fatty acids (EPA and DHA) have anti-inflammatory properties that may help reduce morbidity and mortality from COVID-19 infection.
Taking a regular Omega-3 supplement will not only decrease inflammation and increase immunity, but can improve your overall health in many ways.
Polyphenols are found in foods such as apples, chocolate, red wine, olive oil, and turmeric. Like Omega-3 fatty acids, they help reduce inflammation, which is why researchers believe polyphenols may provide a protective effect against COVID-19 disease.
In a recent study, researchers found that a high intake of polyphenols may have a protective effect and prevent disease progression in patients with COVID-19 and may help protect the body from the harmful effects of the disease.
5. Vitamin B-Complex
Vitamin B6 is an essential nutrient for immune system health. Vitamin B12 plays an important role in white blood cell production and is crucial for a healthy immune system.
As Vitamin B12 is only found in animal products, vegetarians and vegans must get their daily requirement of B-Complex Vitamins from a daily multivitamin supplement. Adults over 50 may also require B-Complex supplements as they lose the ability to absorb these vitamins from their diet.
In addition to Vitamin B12, folic acid – also called Vitamin B9 – is another B-vitamin required for immune system health and formation of red blood cells, as it is involved in the production of nucleic acid, protein synthesis, immune cell activity, and various metabolic processes.
As mentioned above, the largest observational study of dietary supplement use in coronavirus infection found that taking multivitamins may reduce the risk of testing positive for the COVID-19 coronavirus among women – but not in men.
But, whether you’re a woman or a man, making sure that you get all your B-vitamins as part of your daily diet in the form of a health supplement is a very good idea during a pandemic.
Although the study mentioned above found that taking vitamin C, zinc, or garlic supplements was not associated with a lower risk of testing positive for the Sars-Cov-2 coronavirus in women, it is a well-known fact that taking a zinc supplement can help fight other cold viruses, such as the rhinovirus.
Zinc can also lessen the symptoms of colds, such as nasal congestion, runny noses, sore throat, and cough and can improve immune system health by helping the body produce and activate T-lymphocyte immune cells.
Zinc is an essential mineral that keeps the immune system strong, helps heal wounds, supports normal growth, and is a popular treatment for the common cold. You may be at risk for zinc deficiency if you’re a strict vegetarian, drink alcohol, or have a poor diet.
7. Vitamin C
In the latest study, taking Vitamin C was not associated with a lower risk of testing positive for the Sars-Cov-2 coronavirus in women. But that does not mean Vitamin C is not important for immune system health.
Vitamin C (also called ascorbic acid) can help you get over a cold faster and make the symptoms less severe. It also fights free radicals, promotes the growth and repair of tissues and accelerates wound healing.
Besides having antioxidant and anti-inflammatory activity, which can help improve immune function, Vitamin C promotes the growth and spread of lymphocytes – immune cells that produce antibodies.
Scientists are studying the efficacy of high doses of Vitamin C in decreasing lung inflammation, but as of now, there is no evidence to support the use of oral Vitamin C supplements in preventing or treating COVID-19.
However, Dr Anthony Fauci, said in an interview that he took vitamin D and C supplements to increase immunity, and there is plenty of evidence that being deficient in either nutrient can make you more susceptible to infection.
Since our bodies cannot manufacture Vitamin C, we must consume sufficient amounts of it in our diet. This is not difficult because there are abundant dietary sources of this water-soluble vitamin – from orange juice to fresh fruits and vegetables.
Now that you know the best vitamins and supplements to boost immune system health and increase immunity, you can find out what to eat to boost immune system health.
Including these healthy foods to boost immunity into a diet to boost your immune system can help you protect yourself and your family from infection.
How Laughter Boosts Immunity
The health benefits of laughter are well-known thanks to the efforts of Norman Cousins, who experienced a remarkable cure thanks to the positive effects of laughter on emotional and physical health.
In his book, Anatomy of an Illness, Cousins illustrated how laughter therapy helped him heal from ankylosing spondylitis – a chronic inflammatory disorder that failed to respond to standard medical therapy.
In addition to high-dose intravenous Vitamin C (ascorbic acid infusions), he watched funny videos like Candid Camera, The Three Stooges, and the Marx Brothers. His pain began to diminish and he was totally healed and returned to work.
Today, thanks to research we know that that the advantages of laughter include increased immune system response, production of antibodies and activation of the body’s protective cells.
Laughter therapy benefits include a positive effect on modulating components of the immune system and increased immune activity, including T-cells and especially Natural Killer (NK) cells’ killing activity of tumour cells.
Laughing is good for health because laughter increases immune system response, can lower stress hormones, improve mood, lower bad cholesterol and systolic blood pressure, and increase good cholesterol (HDL).
So enjoy the health benefits of laughter by making time for a good belly laugh every day and remember that prioritizing yourself and taking care of yourself first is the best thing you can do for your well-being.
