What Vitamins Can Help Prevent Covid
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
Zinc has also been found to help produce and activate T-cells , which trigger the body to respond to infections, according to the NIH.
Cansupplements Help Your Immunity
While vitamins andsupplements can help fill in the gaps in your diet, the best way to load up onessential nutrients is to get them straight from food.
Your body absorbs and usesvitamins and nutrients better when they come from a dietarysource. When its a vitamin or supplement, its often questionablehow much youre actually getting. Because supplements are regulated asfoods, not as drugs, the Food and Drug Administration doesnt evaluate thequality of supplements or assess their effects on the body.
Some supplements may have side effects, especially if taken before surgery or with other medicines. Supplements can also cause problems if you have certain health conditions. And the effects of many supplements havent been tested in children, pregnant women and other groups.
Its especially important to avoid taking vitamin E supplements. Not only is there little clinical research showing that vitamin E supplements benefit your health, but they may also be harmful in some situations.
For these reasons, expertssay its best to get vitamins through food rather than supplements.
Talk with yourhealthcare provider if youre thinking about taking dietary supplements,Zumpano says.
Is Changing What I Eat Enough To Prevent Covid
Taking steps to improve your lifestyle in a way that will strengthen your immune system doesnt mean this will stop you from getting sick. However, its important to focus on what you do have control over during this time.
Focusing on healthy food choices to help your immune system is one area where you do have control, and this can help you to fight any infection that does make you sick.
- Washing your hands often with soap and water for at least 20 seconds
- Using a tissue to cover your mouth when you cough or sneeze and dispose of immediately
- Avoid touching your face if your hands are not clean
- Clean and disinfect frequently touched surfaces and objects, such as doorknobs
As well as keeping yourself clean, give your home life a clean as well. Focus on cleaning the surfaces that you would touch frequently such as doorknobs, desks, keyboards, mobile phones, as well as your kitchen and bathroom.

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.
Elderberry
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
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
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.
Selenium
Garlic
Garlics antiviral properties may be helpful in reducing the severity of symptoms in colds, flu or COVID-19 infections.

Defining The Immune System
Unlike many other systems of the body, which have distinct, easily identifiable organs and tissues, the immune system is complex. It contains numerous types of cells and tissues that both reside in other tissues and circulate throughout the body. A multi-layered shield for the body, the immune system is incredibly hard-working.
The immune system’s tissues perform diverse roles: The skin serves as a literal barrier to invaders, lymphatic fluid continually circulates to rid cells of everyday toxins and lymph nodes serve as filters for the body. While technically part of the circulatory system, the immune system’s tissues comprise parts of the digestive, endocrine, respiratory, and even the skeletal systems. While no system of the body operates autonomously, the immune system has an especially symbiotic relationship with the body’s other systems. The immune system knows no boundaries its cells go everywhere.
Keeping the immune system in balance is of the utmost importance in all stages of life. As the natural defense system, it is designed to spring into action to support every area of the body. If your body is your castle, your immune system acts as the soldiers patrolling the perimeter and every corridor within the walls.
What Are The Best Alternatives
Besides following a high protein, sugar-free, gluten-free and dairy-free organic diet, while exercising regularly, getting enough sleep, and engaging in anti-stress programs like meditation, what else can you do to boost immunity against colds and flus? Taking plenty of vacations in warm climates helps and so does laughter. Are food allergies and sensitivities important? Can you prevent more serious illnesses such as cancer and autoimmune disorders using a natural supplement regime? And, will these all work without side effects?
Food Allergy/Sensitivity Testing Food allergies, intolerances or hypersensitivities are unsuspected factors in the development of many worldwide killer diseases such as recurrent infections, cancer, heart disease, diabetes, asthma and just about every autoimmune disease . Over 90% of the documented adverse reactions to foods are not true allergies, occur on a delayed basis , and will avoid detection by conventional skin scratch tests. They are often referred to as Type 2 Allergies and they may have either immune or non-immune system mechanisms.
The most accepted method of identifying these non-classical food reactions is by an elimination diet. This is accomplished by following a hypoallergenic diet for three weeks, which eliminates the most commonly eaten foods . After three weeks, the body is then challenged with the eliminated foods one by one, noting the reactions.

Cut Back On Hand Sanitizer
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.
Diabetes And Its Relationship To Infections Including Covid
If your diabetes is well-controlled, your immune system is likely working very well and you do not have a greater risk of infections from viruses, including COVID-19. In other words, living with type 1 or type 2 diabetes does not put you at greater risk for getting an infection. However, COVID-19 can cause more severe complications for some people living with diabetes, especially the elderly, those with cardiovascular disease or those who are obese. In addition, poorly controlled blood sugar has been found to contribute to COVID-19-associated hospitalizations for people with type 1 or type 2 diabetes.

Effects Of Antioxidant Vitamins On Immunity
It has been known for more than 30 years that some vitamins with antioxidant properties, including vitamin A, vitamin B6 , vitamin C and particularly vitamin E, have protective effects on animal models of atherosclerosis and ischaemia-reperfusion injury . Vitamin E collectively refers to eight related compounds , of which -tocopherol has the greatest bioavailability and is the best characterized. Vitamin E decreases the release of reactive oxygen species by monocytes and the expression of CD11b and very late antigen 4 , thereby decreasing monocyte adhesion to the endothelium. Vitamin E also blocks the release of pro-inflammatory cytokines, including IL-1, IL-6, TNF and the chemokine IL-8, by monocytes and macrophages,. Moreover, vitamin E prevents the upregulation of the adhesion molecules vascular cell-adhesion molecule 1 and intercellular adhesion molecule 1 on the endothelium induced by oxidized low-density lipo protein and IL-1, as well as the upregulation of E-selectin and some chemokines. Reactive oxygen species activate the nuclear factor-B pathway, which initiates many pro-inflammatory events. Therefore, the therapeutic antioxidant effect of these vitamins could be explained, at least in part, by their capacity to decrease NF-B activation.
Can You Strengthen Your Immune System
Dr. Cassel says another common misconception is having a “strong” immune system is what’s best for your body.
“You actually don’t want your immune system to be stronger, you want it to be balanced,” Dr. Cassel says. “Too much of an immune response is just as bad as too little response.”
Dr. Cassel says most of the things people take to boost their immune system, such as vitamins or supplements, don’t have any effect on your immune response.

Increase Immunity The Healthy Way
Many products on store shelves claim to boost or support immunity. But the concept of boosting immunity actually makes little sense scientifically. In fact, boosting the number of cells in your body immune cells or others is not necessarily a good thing. For example, athletes who engage in “blood doping” pumping blood into their systems to boost their number of blood cells and enhance their performance run the risk of strokes.
Attempting to boost the cells of your immune system is especially complicated because there are so many different kinds of cells in the immune system that respond to so many different microbes in so many ways. Which cells should you boost, and to what number? So far, scientists do not know the answer. What is known is that the body is continually generating immune cells. Certainly, it produces many more lymphocytes than it can possibly use. The extra cells remove themselves through a natural process of cell death called apoptosis some before they see any action, some after the battle is won. No one knows how many cells or what the best mix of cells the immune system needs to function at its optimum level.

Zinc For Reducing Cold Durations
Zinc is another popular option that many people recommend when trying to shorten the duration of a cold. While the mineral cant prevent colds, evidence supports the claim that zinc shortens colds. According to one study, colds were shortened by 30-40% in people who took zinc lozenges. However, people thinking about adding zinc to their cold recovery plan should look for supplements or lozenges that contain at least 80-100mg of zinc. And for best results, try to take zinc within the first 24 hours of experiencing cold symptoms.
Here Are Some Myths And Facts About Immune
Myth: Vitamin C prevents illness.
Turning to large doses of vitamin C in the winter to avoid getting sick doesn’t work. However, vitamin C may shorten the duration of a cold once you’re already under the weather. Vitamin C is also an antioxidant, and those anti-inflammatory properties may reduce swollen sinuses.
Myth: Zinc boosts your immune system.
Much like vitamin C, there’s not enough evidence to support taking extra zinc to keep sickness at bay. Meeting daily zinc requirements is important for a healthy immune system, but exceeding these requirements can be toxic. In 2009, the Food and Drug Administration warned consumers to stay away from zinc nasal sprays after studies found they could damage the sense of smell.
Fact: Chicken soup is a cure-all.
The healing benefits of chicken soup are numerous, according to the National Institutes of Health. Not only is grandma’s home remedy heartwarming, but it also has properties that fight inflammation, promote hydration and get mucus flowing.
Myth: Dairy increases mucus production.
Some swear that milk and other dairy products make a phlegmy illness worse, but there’s no science behind it. Most studies have found no relationship between eating dairy and increased mucus production.

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.
Can You Really Boost Your Immune System
Jun 01, 2020Cedars-Sinai Staff
The idea of boosting your immune system is appealing, but is it even possible to build up your immune system so that you rarely get sick?
Dr. Suzanne Cassel, an immunologist at Cedars-Sinai, says that the concept of boosting your immune system is inaccurate. There’s also widely held confusion about how your immune system functions and how your body is designed to combat diseases and infections.
“You actually don’t want your immune system to be stronger, you want it to be balanced.”

Sleep A Natural Immunity Booster
Sleep is essential for the health of your body and brain. When you dont get enough sleep your natural immune cells go down, and inflammation cells go up. Good sleep helps strengthen your immune system. Adults should try for at seven to eight hours of sleep a day. Children and teens need more sleep.
Immune System Booster Vitamins
When talking about immunity, we often might refer to a desire to ‘boost’ our immune system but in reality, we don’t actually want this to happen, as Dr Ruxton explains.
‘Like many other body systems, such as blood glucose levels or brain oxygen levels, our immune response works across a tight optimal range,’ she says. ‘Too low, and our sluggish system will not successfully attack and contain pathogens.
‘Too high, and we are at risk of developing so-called autoimmune conditions where the bodys overreactive immune response starts to attack normal healthy tissue. Examples of these conditions include type 1 diabetes, multiple sclerosis, rheumatoid arthritis and psoriasis.’
Instead, you should look make sure your immune system is functioning optimally, and that’s where nutrition getting the right vitamins for immune system comes in.
