How Vitamin C Supports A Healthy Immune System

How to improve your immune system with vitamins amid COVID-19 pandemic

Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Because your body cannot make vitamin C, it must come from the foods you eat every day.

Research shows vitamin C is essential for the growth and repair of tissue all over the body. Vitamin C helps heal wounds and repair and maintain healthy bones, teeth, skin and cartilage a type of firm tissue that covers the bones. As an antioxidant, vitamin C fights free radicals in the body which may help prevent or delay certain cancers and heart disease and promote healthy aging. Vitamin C from foods also seems to reduce the risk of cartilage loss in those with osteoarthritis.

Though it may not keep you from catching a cold, there is some evidence that high doses of vitamin C may decrease the length of cold symptoms by as much as one to one-and-a-half days for some people. However, other studies did not result in the same findings, and the risk of side effects is greater with high doses of vitamin C supplements, so check with your doctor or registered dietitian nutritionist before taking.


Zinc And Vitamin C For A Healthy Immune System

If your immune system is weak because of a particular vitamin or mineral deficiency, then supplementing with that nutrient may lead to improvements.

According to the National Institute of Health’s Fact Sheet on zinc, zinc lozenges may reduce the duration and severity of the common cold, especially if taken soon after the onset of illness. However, it is important to note that zinc nasal sprays should be avoided due to the serious side effects.

Although vitamin C is commonly-known as a cold remedy, the results of clinical trials are mixed. The use of vitamin C after the onset of cold symptoms has not been shown to effectively reduce the length or symptoms of the common cold. However, the National Institute of Health’s Fact Sheet on vitamin C states that regular vitamin C intake of 250 mg/day to 1 g/day can be extremely helpful in people who regularly participate in intense physical exercise or are routinely exposed to constant cold environments. In these cases, the incidence of cold was reduced by 50% with the use of vitamin C.

Realistically, vitamin and mineral supplements are most effective as a support for your immune system. If you do become ill, doctors recommend that you drink plenty of fluids, get plenty of rest, and visit a doctor if your symptoms do not improve within a few days.

Effects On Immunoglobulin Isotypes

An important feature of activated B cells is their capacity to undergo immunoglobulin class-switching and to give rise to different antibody isotypes. TH1- and TH2-cell cytokines differentially influence antibody class-switching: the TH1-cell cytokine IFN promotes switching to IgG2a and IgG3, whereas the TH2-cell cytokine IL-4 induces the production of IgG1 and IgE and suppresses the generation of IgG2b and IgG3 . DCs can also modulate B-cell activation and antibody class-switching, which could occur indirectly by influencing TH-cell differentiation. However, DCs can also directly promote the induction of specific immunoglobulin isotypes. GALT-resident DCs efficiently induce the generation of IgA+ ASCs when cultured with activated B cells in vitro,. Several cytokines and other bioactive factors are involved in the capacity of GALT-resident DCs to induce IgA+ ASCs, including TGF1 , IL-6 , APRIL and nitric oxide.

Antioxidants For Antiviral And Immune Function Protection

Our Super Plus C contains Vitamin C and curcumin, two powerful nutrients that are anti-viral and help to support immune function.Vitamin C is an antioxidant vitamin known to reduce intracellular oxidative stress and enhance neutrophils phagocytic capacity phagocytes are kind of like little Pac Men in our immune system that eat up viruses. Curcumin is known to suppress pro-inflammatory cytokines like interleukin-1 and interleukin-6. Cytokines can cause a cytokine storm that increases the severity and complications of Covid-19, and curcumin can help to prevent this. It also suppresses tumor necrosis factor alpha, helping to inhibit viruses from taking hold in the body.

Curcumin specifically protects the lungs through its antihistamine and anti-inflammatory bronchodilator properties. It supports ACE-2 receptors and we know that COVID-19 goes after the ACE receptors in our body, which are so prevalent in our lungs. This is why so many people are having respiratory issues with coronavirus, and curcumin certainly can help with this.

What Vitamins Can Help Prevent Covid

Vital Nutrients

Because COVID-19 comes with cold and flu-like symptoms, Vitamins B, C and D, as well as zinc may be helpful in boosting your immune system and fighting the illness in the same way they can help you get over a cold or flu.

Vitamin C

Generally, vitamin C can help you fight a cold faster or ease your cold symptoms if you were taking it prior to getting sick. As an antioxidant, vitamin C can help reduce inflammationand lung inflammation is a severe symptom of COVID-19, which can lead to respiratory distress or even death. So if youre still healthy, it doesnt hurt to start taking vitamin C now.

Vitamin D

The primary function of vitamin D is to help your body maintain optimal blood levels of calcium and phosphorous, which you can get through exposure to the suns ultraviolet rays, or through supplements and the foods you eat.

Getting enough vitamin D can also protect you from respiratory infection. Vitamin D supplementation significantly decreases the chance of respiratory tract infections, based on clinical studies published in the Journal of Pharmacology and Pharmacotherapeutics.

B Complex vitamins

Vitamin B6 is essential to keeping your immune system in top condition. Be sure to get enough vitamin B as a supplement, as part of your daily diet or in a multivitamin.


Zinc has also been found to help produce and activate T-cells , which trigger the body to respond to infections, according to the NIH.

Support Your Immune Function With Good Nutrition

One of the most valuable things you have is your health. As a dietitian, I have received numerous queries about recommended foods, supplements and diet patterns to boost immune function. While it is true that nutrition plays a large role in immune function, diet recommendations for the prevention of acute illnesses, like COVID-19 and other viruses, don’t look a whole lot different than general guidelines for healthy eating.

I’ll start by saying that the concept of boosting the immune system through diet is flawed, as boosting refers to something that is stimulated above the normal level. A good diet cannot boost the immune system, but it’s important to maintain a functional immune system by avoiding immunodeficiency due to malnutrition or micronutrient deficiencies.

It’s important to note that no single food or nutrient will prevent illness. Also, the immune system is incredibly complex and influenced by a variety of other factors, including stress level, age, sleep and other medical conditions.

A few key micronutrients have been identified as critical for the growth and function of immune cells, including:

Need a multivitamin or mineral supplement?

A general multivitamin or mineral supplement providing no more than 100% of your recommended daily allowance can be used and is generally safe for many people. Your health care provider may recommend further supplementation based on your lab values or medical status.


Probiotics Good Bugs For Strong Immunity

I love our Super Biotic because it helps to support the immune system that lives in our gut by giving it good bacteria. Did you know that approximately 75% of our immune system resides in our gastrointestinal tract? It is found among this bacteria, so it’s important that we supplement and feed good bacteria to our GI tract.

A probiotic is something I have almost all my patients taking as part of a holistic view of how to support the body. Remember, the virus is not a living organism and it needs a host where it can replicate. If the hosts immune system is robust and healthy and able to handle things, then the virus is not going to have a comfortable place to set up shop and it’s not going to have an impact.

Taking this approach of making the body resilient and ready for action, we have grouped Super Biotic and Super C Plus into an Immune Support Combo bundle to make it easier for you to get these all these wonderfully protective vitamins and nutrients. This is one area of your life where you dont want to be a good host!

If you’re looking to “boost” your immunity against harmful germs, the first thing to understand is no one magical supplement or diet can do the job.

The immune system is a complex network of cells, tissues, and organs that help the body fend off infection from outsider invaders, like bacteria, viruses, fungi, and toxins. It’s a highly adaptive, complex biological system that requires balance between all parts to function properly.

This means optimal immune health relies on a multifaceted approach that focuses on making healthy lifestyle choices.

To ensure your immune system is as strong as it can be against outside invaders, here are practical tips worth incorporating into your everyday life.

Cut Back On Hand Sanitizer

COVID-19: Experts say these supplements may help immune system be strong | ABC7

Yes, hand sanitizer is known for killing germs that cause illness. But studies have shown that only hand sanitizers with 60 to 95 percent alcohol are effective at killing germs. Those with lower alcohol concentrations, the U.S. Centers for Disease Control states, may cause germs to become resistant to the sanitizing agent. Plus, hand sanitizers are less effective at bacterial removal compared to regular soap and water.

Tip to remember: Wash your hands with soap and water frequently. In circumstances when you cant wash your hands, opt for hand sanitizer. Just dont swap the antibacterial for soap.

Peptide Therapy Can Boost Your Immune System

A peptide is a short chain of amino acids linked together that can be thought of as a small protein. In our bodies, these small proteins typically act as signalling molecules. They bind to receptors on the cell surface and tell other cells and molecules what to do. By attaching to receptor proteins on the surface of individual cells, peptides will stimulate how they respond to certain stimuli that support cellular communication. As naturally occurring biological molecules, they play an essential role in any form of biological activityPeptide therapy naturally produces peptide in the thymus gland and lymphoid tissue to support immune function. It basically helps the body’s ability to protect against foreign invaders that can harm the body. It has been studied extensively for its ability to enhance the immune system of cancer patients undergoing chemotherapy. It is also useful in stabilising your immune system that it is effective for treating many conditions such as bacterial infections, viral infections, and cancer.In conclusion, a healthy immune system protects us from antigens entering the body. It is very important to ensure that our immune system is in optimal condition in order to fight any health challenges that might arise.

Signs Of A Strong Immune System

When you have poultry, the immune system is activated. As a result, your body can quickly detect pathogens and antigens.

When these foreign substances enter your body, your immunity sends warning signals and triggers a defense mechanism to prevent these harmful organisms.

Check these some signs that you have a robust immune system:

  • You havent caught a cold or the flu this winter …
  • Youre not constantly tired, and as such, your immune system must be as well…
  • When given a flu shot, it takes about 24 hours before getting sick with the strain you offered…
  • Get tested for something via blood work especially your white blood cells, and the results were negative, which means your immunity has done its job and is alive and kicking…
  • If ever came down with something, such as a cold or flu, it didnt last more than 4-7 days…
  • Following a mosquito sting, you may get a little red bump on your skin. That itchy sensation is an indication that your immune response system is preventing unwanted infections.
  • However, thats not all! Several organs in the immune system operate as barriers against foreign materials and keep us safe.

    A robust immune system, for example, causes the manufacture of antibodies, white blood cells, and T cells to occur, which seek out and destroy antigens.

    Diet And Your Immune System


    Like any fighting force, the immune system army marches on its stomach. Healthy immune system warriors need good, regular nourishment. Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases. For example, researchers don’t know whether any particular dietary factors, such as processed foods or high simple sugar intake, will have adversely affect immune function. There are still relatively few studies of the effects of nutrition on the immune system of humans.

    There is some evidence that various micronutrient deficiencies for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E alter immune responses in animals, as measured in the test tube. However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed.

    So, what can you do? If you suspect your diet is not providing you with all your micronutrient needs maybe, for instance, you don’t like vegetables taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system. Taking megadoses of a single vitamin does not. More is not necessarily better.

    What Does The Latest Medical Research Show

    The immune system involves many different cells, tissues, and organs working together to protect the body from foreign bodies, infections, and other diseases. However, the immune system can only function at its best when sufficient nutrients are available.

    There are many different types of natural supplements and herbal supplements said to help the body strengthen its ability to fight off disease. Dietary supplements involve a concentrated form of various types of nutrients and are aimed at increasing the level of nutrients the body absorbs. They can include vitamins, minerals, herbal supplements, amino acids, and enzymes.

    What Are The Best Supplements To Take During Covid

    Whether eaten as a whole food or in the form of a pill, the following supplements may help keep you healthy and your immune system in top shape to combat coronavirus. Once again, benefits are theoretical.


    Full of antiviral and anti-inflammatory properties, elderberry syrup is used as a remedy for colds, flus, and bacterial sinus infections. Elderberry works by reducing swelling in the mucus membranes.

    Some studies suggest elderberry extract reduces the duration of the flu, which is why some believe it may also help your immune system against coronavirus infection.


    Mushrooms are high in selenium and B vitamins like riboflavin and niacin, which are needed to keep the immune system running optimally. Mushrooms are also high in polysaccharides, sugar-like molecules that boost immune function.


    Astragalus is an herb, and its root is used in medicine. Typically used to strengthen the immune system and treat the common cold, upper respiratory infections, seasonal allergies, swine flu, astragalus is also used to fight bacteria and viruses.

    Its effectiveness against illness doesnt have a lot of research behind it, although in treating seasonal allergies, 160 mg of astragalus root extract by mouth daily for 3-6 weeks was found to improve symptoms such as running nose, itching, and sneezing.

    Ra May Promote The Ongoing Immune Response

    Although most evidence shows that, at pharmacological levels, RA inhibits the development of inflammatory cells and induces or expands Tregs, recent work has suggested that RA may also promote T cell activation and T helper cell responses at minimal levels.

    As mentioned above, RA is mainly produced by DC from the gut. Some reports show that RA may also be produced at other sites during an ongoing immune response . We have discussed that RA signaling is initiated during the development of inflammation. Similarly, there is evidence demonstrating that the RAâRARα signaling axis is essential for adaptive CD4+ T cell immunity as RARα-deficient CD4+ T cells were less efficient than wild-type counterparts in polyclonal activation. Also, in RARα-deficient T cells, the phosphorylation of PLCγ and ERK1/2 was reduced, and manifests impaired Ca2+ mobilization and mTOR/AKT activation upon T cell stimulation. Together, RARα may regulate the signaling pathways downstream of T cell receptor engagement .

    Vitamins to boost immune system from COVID-19

    To ensure youre getting enough vitamin D, make sure youre getting regular exposure to sunlight or eating foods rich in vitamin D like fish, eggs, dairy, or fortified foods. If you think you may not be getting the necessary levels, you can fill the gap by taking vitamin D in tablet form. Just make sure to look for vitamin D3, rather than D2. A 2012 study published by the American Journal of Clinical Nutrition, indicates that vitamin D3 is more effective at raising the blood levels of vitamin D. Vitamin D3 has become more popular in pill form, but many foods are still fortified with vitamin D2.
