The immune system is made up of a number of different organs, cells and proteins within the body, which all work together to protect the body from invasion from bacteria and viruses.
There are two different parts that make up the immune system. The innate immune system is the one which you are born with, and the adaptive immune system is the one which you develop as you are exposed to microbes.
These two parts work together to protect you from infections and viruses.

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.

Do Vitamin B12 Supplements Work
Vitamin B12 supplements can treat a deficiency, but dietitians recommend getting your vitamin B12 from food, if possible, before trying a supplement. Many meat and dairy products have vitamin B12. Clams, crab, beef liver and many fish are particularly high in vitamin B12. Eliminating meat, dairy and fortified cereals from your diet may require you to supplement vitamin B12, Sheth said.
“In general, vitamin B12 is found in animal products,” Sheth said, so, strict vegetarians and vegans must actively seek out another source of the vitamin. In people who are making the transition to a vegan diet, a vitamin B12 deficiency may not show up for a while, Sheth said.
Nutritional yeast is the best vegetarian source of vitamin B12, Sheth said. Just 2 teaspoons a day of nutritional yeast should cover an adult’s vitamin B12 needs. Additionally, most multivitamins contain the daily recommended amount of vitamin B12, and fortified cereals typically provide ample vitamin B12.
Other strict diets may unintentionally cut vitamin B12. “A lot of people have cut grains, and a lot of B vitamins are fortified in our grain products,” Mangieri said. “If you’re going to eliminate something from your diet, investigate what you have eliminated and where else you can get those nutrients. You have to really work with a registered dietitian or do your homework.”
What Can Happen If You Are Deficient In Vitamin D
Vitamin D deficiencies can mean your immune system is more vulnerable, but there are some other important conditions to know about too.
“Severe vitamin D deficiency can lead to a condition called rickets in children, and osteomalacia in adults. Osteomalacia is the softening and weakening of bones, and symptoms include joint and bone pain, muscle weakness, difficulty walking and bones that are easily fractured,” Tolentino says.
Another connection that scientists are researching is the link between mood disorders and vitamin D deficiency. Many studies have looked at depression risk specifically, like this one that found a link between vitamin D deficiency and risk for depression in older adults. In another study, adults with depression were given vitamin D supplementation and it did help improve symptoms in many of them.

How Your Immune System Works
Your immune system works to recognize and identify an infection or injury in the body. This causes an immune response, with the goal of restoring normal function.
Dr. Cassel says many people think that when they get sick, their symptoms are a sign that they have a virus or an infection.
However, your symptoms are actually a sign that your body is fighting back against the infection or virus, triggering an immune response.
“When you have a cold, you feel run down, your nose is runny, you feel congestedthese are the symptoms people complain about,” Dr. Cassel says. “People think ‘I’m so sick, this is terrible. Why doesn’t my immune system work?’ But with every one of these cold symptoms, that is your immune system at work.”

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.

Can Supplements Boost Your Immunity This Winter
Nov. 17, 2020 — With COVID-19 cases on the rise and cold and flu season well underway, people are seeking ways to boost their disease defenses. Sales of immune health supplements are projected to grow from $16 billion in 2019 to $29 billion by 2027, spurred in part by the pandemic, according to research from Fortune Business Insights.
But could a supplement give you an extra edge against illness?
âThereâs no magic bullet to bolster the immune system,â says Barry Fox, MD, an infectious disease specialist at the University of Wisconsin School of Medicine and Public Health.
Experts say that a good diet, plenty of sleep, and regular exercise will get you started in the right direction, along with practices like meditation or yoga for stress relief.
But some supplements may have some infection-fighting benefits. âIf people are taking vitamin C or D or another supplement and not having any side effects, it may be of help,â Fox says.
Keep in mind that supplements are an unregulated industry. That means that even if a vitamin or botanical has shown promise, the bottle you buy might contain too little or too much of the desired substance. For most supplements, research is limited at best. Plus, research suggests itâs better to get your vitamins from foods rather than supplements.
That said, hereâs what to know about popular vitamins and botanicals often advertised as immune boosters:

What About Those Good Bacteria
Seventy percent of our immune system is located in our gastrointestinal tract, and the bacteria that live there are critical for the smooth functioning of immune cells. Probiotics are a source of those good bacteria, and another method that has been touted as an boosting immunity.
There have been some studies showing that probiotics can decrease respiratory tract infections, says Dr. Marino. But again, we cannot make that jump to say that probiotic supplementation can prevent coronavirus infection, or reduce the severity of symptoms.
I dont often recommend the average population to take a probiotic supplement, I only suggest it to my patients who may already have GI symptoms says Rubin. But if youre looking for probiotic rich foods, I suggest eating yoghurt, and there are lots of non-dairy options for those who are lactose intolerant. Sauerkraut and kimchi are another good source.

How Does The Immune System Work
The immune system is made possible by white blood cells, which fight diseases and infection. You cant have immunity without endothelium, which is the maestro of the circulation system a very important tissue, Cooke says. Its the portal for circulating white blood vessels when it gets dysfunctional, it acts less like Teflon and more like Velcro, and things begin to stick and cause inflammation.
Allergies and asthma are overreactions of your immune system both go hand-in-hand. Often, the two are mistaken for one another, says Parikh. If you suffer from severe allergies, make sure youre seeing a board-certified allergist people are often misdiagnosed.
The microbiome also plays a large role in immunity. Its home to good bacteria that helps regulate asthma, allergies, and other autoimmune problems where the immune system is overactive, Parikh adds. With the exception of the coronavirus, there can be such a thing as being too clean, especially in Western countries. Antibacterial sanitizers cant differentiate between the good and the bad bacteria, resulting in some everyday environments being over-sanitized.
