Older individuals are generally Lentils variety pack an tips for managing diabetes risk Numerous studies reveal that zinc supplements may protect against respiratory tract infections Immune-bkosting the common cold 19 In a study in 64 hospitalized children with acute lower respiratory tract infections ALRIstaking 30 mg of zinc per day decreased the total duration of infection and the duration of the hospital stay by an average of 2 days, compared with a placebo group Supplemental zinc may also help reduce the duration of the common cold Additionally, zinc demonstrates antiviral activity 23 Taking zinc long term is typically safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc Supplementing with zinc may help protect against respiratory tract infections and reduce the duration of these infections.
Vitamin C is perhaps the most popular supplement taken to protect against infection due to its important role in immune health. This vitamin supports the function of various immune cells and enhances their ability to protect against infection. Vitamin C also functions as a powerful antioxidant, protecting against damage induced by oxidative stress, which occurs with the accumulation of reactive molecules known as free radicals.
Oxidative stress can negatively affect immune health and is linked to numerous diseases Supplementing with vitamin C has been shown to reduce the duration and severity of upper respiratory tract infections, including the common cold Additionally, high-dose intravenous vitamin C treatment has been shown to significantly improve symptoms in people with severe infections, including sepsis and acute respiratory distress syndrome ARDS resulting from viral infections Still, other studies have suggested that the role of vitamin C in this setting is still under investigation 32 The upper limit for vitamin C is 2, mg.
Supplemental daily doses are typically between and 1, mg Vitamin C is vital for immune health. Supplementing with this nutrient may help reduce the duration and severity of upper respiratory tract infections, including the common cold. Black elderberry Sambucus nigrawhich has long been used to treat infections, is being researched for its effects on immune health.
In test-tube studies, elderberry extract demonstrates potent antibacterial and antiviral potential against bacterial pathogens responsible for upper respiratory tract infections and strains of the influenza virus 35 A review of 4 randomized control studies in people found that elderberry supplements significantly reduced upper respiratory symptoms caused by viral infections However, this study is outdated and was sponsored by the elderberry syrup manufacturer, which may have skewed results Though it has been suggested that elderberry can help relieve symptoms of certain infections and the influenza virus, we also must be aware of the risks.
Some report that elderberries can lead to the production of excess cytokines, which could potentially damage healthy cells For that reason, some researchers recommend elderberry supplements only be used in the early course of COVID It should be noted no published research studies have evaluated the use of elderberry for COVID These recommendations are based on previous research done on elderberries.
A systemic review of elderberry 43 concluded:. Taking elderberry supplements may help reduce upper respiratory symptoms caused by viral infections and help alleviate flu symptoms. However, elderberry also has risks. More research is needed. Medicinal mushrooms have been used since ancient times to prevent and treat infection and disease.
Many types of medicinal mushrooms have been studied for their immune-boosting potential. Over recognized species of medicinal mushrooms are known to have immune-enhancing properties Some research demonstrates that supplementing with specific types of medicinal mushrooms may enhance immune health in several ways as well as reduce symptoms of certain conditions, including asthma and lung infections.
For example, a study in mice with tuberculosis, a serious bacterial disease, found that treatment with cordyceps significantly reduced bacterial load in the lungs, enhanced immune response, and reduced inflammation, compared with a placebo group In a randomized, 8-week study in 79 adults, supplementing with 1.
Turkey tail is another medicinal mushroom that has powerful effects on immune health. Research in humans indicates that turkey tail may enhance immune response, especially in people with certain types of cancer 48 Many other medicinal mushrooms have been studied for their beneficial effects on immune health as well.
Medicinal mushroom products can be found in the form of tinctures, teas, and supplements 505152 Many types of medicinal mushrooms, including cordyceps and turkey tail, may offer immune-enhancing and antibacterial effects.
According to results from scientific research, the supplements listed above may offer immune-boosting properties. However, keep in mind that many of these potential effects these supplements have on immune health have not been thoroughly tested in humans, highlighting the need for future studies.
Astragalus, garlic, curcumin, and echinacea are just some of the supplements that may offer immune-boosting properties. Still, they have not been thoroughly tested in humans. Many supplements on the market may help improve immune health. Zinc, elderberry, and vitamins C and D are just some of the substances that have been researched for their immune-enhancing potential.
However, although these supplements may offer a small benefit for immune health, they should not and cannot be used as a replacement for a healthy lifestyle. Aiming to eat a nutrient-dense balanced diet, getting enough sleep, engaging in regular physical activity, and not smoking or considering quitting, if you smoke are some of the most important ways to help keep your immune system healthy and reduce your chances of infection and disease.

Salmon, tuna, pilchards, and other oily fish are a rich source of omega-3 fatty acids. According to a report , long-term intake of omega-3 fatty acids may reduce the risk of rheumatoid arthritis RA. RA is a chronic autoimmune condition that occurs when the immune system mistakenly attacks a healthy part of the body. Broccoli is another source of vitamin C. It also contains potent antioxidants, such as sulforaphane. For these reasons, it is a good choice of vegetable to eat regularly to support immune system health. Sweet potatoes are rich in beta carotene , a type of antioxidant that gives the skin of the potatoes its orange color. Beta carotene is a source of vitamin A. It helps to make skin healthy and may even provide some protection against skin damage from ultraviolet UV rays. Spinach may boost the immune system, as it contains many essential nutrients and antioxidants, including :. Vitamins C and E can help support the immune system. Research also indicates that flavonoids may help to prevent the common cold in otherwise healthy people. People use ginger in a variety of dishes and desserts, as well as in teas. According to a review, ginger has anti-inflammatory and antioxidative properties and is likely to offer health benefits. However, more research is necessary to confirm whether or not it can effectively prevent illness. One review looked at whether taking garlic supplements containing allicin reduced the risk of getting a cold. The group of participants taking a placebo had more than double the number of colds between them than those taking the garlic supplements. However, the researchers concluded that more research is necessary to determine whether or not garlic can help to prevent colds. Green tea contains only a small amount of caffeine, so people can enjoy it as an alternative to black tea or coffee. Drinking it may also strengthen the immune system. As with blueberries, green tea contains flavonoids, which may reduce the risk of a cold. Kefir is a fermented drink that contains live cultures of bacteria that are beneficial for health. Initial research suggests that drinking kefir may boost the immune system. According to a review , various studies have shown that regular consumption of kefir can help with:. The majority of the research that supports this was carried out on animals or in a laboratory. Researchers need to perform additional studies to understand how kefir may prevent disease in humans. Sunflower seeds can make a tasty addition to salads or breakfast bowls. They are a rich source of vitamin E , an antioxidant. In the same way as other antioxidants, vitamin E improves immune function. It does this by fighting off free radicals, which can damage cells. Close search. Just added to your cart.

Immune-boosting energy -
There are many foods with high water content such as cucumbers, watermelon, and celery. If you have a hard time drinking plain water, try a cup of green tea with lemon, watermelon, cucumber or mint-infused water for an immune system powerhouse beverage.
Think of proper hydration as a way to make it easier for immune-boosting nutrients to get to where they need to go cells in your body. Immune system cells need zinc to function as they are intended. Zinc is a mineral that our body does not store or produce.
While oysters have the highest food content of zinc, there are several other options such as shellfish crab, clams, lobster, and mussels , poultry chicken or turkey , red meat and beans.
Zinc is also found in fortified cereals and some breads, but the best absorption comes from animal-based foods. As you take stock of this information, consider layering the practice of mindful eating to your plan.
Mindful eating is a way to be present, focused and tuned in to the pleasure of eating. This practice can also help decrease stress which can adversely affect your immune system. As you sit down to enjoy your meals, possibly with friends or family members, take time to consider where your food came from, the journey the food took to get to your plate, its taste, texture, and aroma.
The practice of mindful eating helps us slow down, stay in the moment and reconnect to the food that fuels our bodies. Bon appetit!

The immune system is precisely that — a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don't know about the intricacies and interconnectedness of the immune response.
For now, there are no scientifically proven direct links between lifestyle and enhanced immune function. But that doesn't mean the effects of lifestyle on the immune system aren't intriguing and shouldn't be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans.
In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.
Immunity in action. A healthy immune system can defeat invading pathogens as shown above, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them see arrows.
Your first line of defense is to choose a healthy lifestyle. Following general good-health guidelines is the single best step you can take toward naturally keeping your immune system working properly.
Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these:. 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. As we age, our immune response capability becomes reduced, which in turn contributes to more infections and more cancer.
As life expectancy in developed countries has increased, so too has the incidence of age-related conditions. While some people age healthily, the conclusion of many studies is that, compared with younger people, the elderly are more likely to contract infectious diseases and, even more importantly, more likely to die from them.
Respiratory infections, including, influenza , the COVID virus and particularly pneumonia are a leading cause of death in people over 65 worldwide. No one knows for sure why this happens, but some scientists observe that this increased risk correlates with a decrease in T cells, possibly from the thymus atrophying with age and producing fewer T cells to fight off infection.
Whether this decrease in thymus function explains the drop in T cells or whether other changes play a role is not fully understood. Others are interested in whether the bone marrow becomes less efficient at producing the stem cells that give rise to the cells of the immune system.
A reduction in immune response to infections has been demonstrated by older people's response to vaccines. For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is less effective compared to healthy children over age 2.
But despite the reduction in efficacy, vaccinations for influenza and S. pneumoniae have significantly lowered the rates of sickness and death in older people when compared with no vaccination. There appears to be a connection between nutrition and immunity in the elderly.
A form of malnutrition that is surprisingly common even in affluent countries is known as "micronutrient malnutrition. Older people tend to eat less and often have less variety in their diets.
One important question is whether dietary supplements may help older people maintain a healthier immune system. Older people should discuss this question with their doctor. 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. Walk into a store, and you will find bottles of pills and herbal preparations that claim to "support immunity" or otherwise boost the health of your immune system. Although some preparations have been found to alter some components of immune function, thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease.
Demonstrating whether an herb — or any substance, for that matter — can enhance immunity is, as yet, a highly complicated matter. Scientists don't know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity.
Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress.
Despite the challenges, scientists are actively studying the relationship between stress and immune function. For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another.
When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate. The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors.
Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work.
Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical.
In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken.
Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress. Almost every mother has said it: "Wear a jacket or you'll catch a cold!
Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season.
Also the influenza virus stays airborne longer when air is cold and less humid. But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection.
But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures. They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies.
The results have been mixed.
