Immune system boosters -

When it comes to preventing and fighting off colds, vitamin E tends to take a backseat to vitamin C. However, this powerful antioxidant is key to a healthy immune system. Nuts, such as almonds , are packed with the vitamin and also have healthy fats. Adults only need about 15 mg of vitamin E each day.

Sunflower seeds are full of nutrients, including phosphorous , magnesium , and vitamins B6 and E. Vitamin E is important in regulating and maintaining immune system function. Other foods with high amounts of vitamin E include avocados and dark leafy greens.

Sunflower seeds are also high in selenium. Just 1 ounce contains nearly half the selenium that the average adult needs daily. A variety of studies , mostly performed on animals, have looked at its potential to combat viral infections such as swine flu H1N1.

You may know turmeric as a key ingredient in many curries. This bright yellow, bitter spice has also been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. Research shows that high concentrations of curcumin , which gives turmeric its distinctive color, can help decrease exercise-induced muscle damage.

Curcumin has promise as an immune booster based on findings from animal studies with antimicrobial properties. More research is needed. Both green and black teas are packed with flavonoids , a type of antioxidant. Where green tea really excels is in its levels of epigallocatechin gallate EGCG , another powerful antioxidant.

Research has suggested that EGCG may have antiviral properties that support the immune system. The fermentation process black tea goes through destroys a lot of the EGCG. Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved.

Papayas also have a digestive enzyme called papain that has anti-inflammatory effects. Papayas have decent amounts of potassium , magnesium, and folate , all of which are beneficial to your overall health. Like papayas, kiwis are a rich source of essential nutrients, including folate, potassium, vitamin K , and vitamin C.

The soup may help lower inflammation, which could improve symptoms of a cold. Poultry, such as chicken and turkey, is high in vitamin B6. About 3 ounces of light turkey or chicken meat contains nearly one-third of your daily recommended amount of B6. Vitamin B6 is an important player in many of the chemical reactions that happen in the body.

Stock or broth made by boiling chicken bones contains gelatin , chondroitin, and other nutrients helpful for gut healing and immunity.

Too much zinc can actually inhibit immune system function. You may want to focus on eating a balanced diet with plenty of fresh foods and whole grains, engage in at least minutes of physical activity per week, get enough sleep, manage stress with deep breathing or talk therapy, avoid or quit smoking, and limit alcohol consumption.

Preliminary research suggests vitamin C may be involved in the development and function of white blood cells. It seems vitamin C may improve the reproduction of B- and T-cells , which are important white blood cells for the immune system.

The amount of vitamin C needed for increasing white blood cells may depend on the condition and overall health needs.

More research in humans is needed to better understand the link between vitamin C and white blood cells. To raise your white blood cell count , you may want to avoid alcohol and tobacco use, take Omega-3s and zinc, and eat a balanced diet.

For example, a study found that the Mediterranean diet had an effect on the white blood cell counts of adults at risk for cardiovascular disease. Depending on the cause of low white blood cells, you may also need to take medications like myeloid growth factors.

Antiviral foods may include fermented vegetables kimchi , fermented milk yogurt and kefir , herbs oregano, fennel, peppermint, and aloe vera , garlic, ginger, turmeric, black cumin, cinnamon, licorice root, mushrooms, and citrus fruits. Some foods may boost your immune system while others will help with their antimicrobial properties.

This means they may help fight bacteria, viruses, and other pathogens that cause infections. Examples include herbs and spices oregano , cinnamon , clove , and rosemary , cruciferous vegetables kale and rutabaga , citrus fruits, parsley , and a wide range of other plant-based foods.

Eating a variety of vegetables may help you boost your immune system. Red peppers, spinach, and broccoli are good choices, as well as ginger, turmeric, and garlic.

Eating all types of fresh fruits regularly may help your immune system function well. Bananas, in particular, contain a substance called lectin. One study in rodents found that banana lectin may enhance the immune system.

Fresh foods can provide our bodies with the nutrients our immune system needs to work correctly. You need a variety of fruits, vegetables, whole grains, herbs, and spices in your diet to enable your body to stay as healthy as possible.

Good choices of foods to boost the immune system include citrus fruits, spinach, almonds, papaya, and green tea. Although eating a balanced diet is key to boosting your immunity, foods alone cannot and should not replace medical treatment, unless your healthcare professional recommends it.

IV drips, supplements, cleanses, and superfoods The lineup of immune-boosting products and advice includes: Home intravenous IV drips. Want a health professional to come to your home with IV fluids containing various vitamins and supplements?

That's available in many US cities, and some companies claim their formula is designed to supercharge immunity. These on-demand IV treatments aren't risk-free and can be quite expensive.

Vitamins and supplements. Popular options include turmeric, milk thistle, and echinacea, often in combination with various vitamins. Hundreds of formulations are available. Superfoods and foods to avoid. If you search online for "foods to boost the immune system" you'll see thousands of articles touting blueberries, broccoli, spinach, dark chocolate, and other foods to keep infections away.

There's also a list of foods to avoid, such as sugary drinks or highly processed meats, because they're supposed to be bad for your immune system. Cleanses and detox treatments. No doubt you've seen pitches for cleanses and detox products intended to remove toxins from the body.

Their marketing warns that the environment is full of harmful substances that get into the body through the air, water, and food, which we need to remove. Advocates suggest that, among other harmful effects, these often unnamed toxins make your immune system sluggish. Are the heavily marketed IV drips, supplements, or detox products endorsed by the FDA?

More importantly, they're confusing: Boosting immunity is what vaccinations do. They prime your immune system to help fight off a specific infectious organism like the flu shot before each flu season.

Immune support typically describes vitamins such as vitamin C , or other nutrients necessary for a healthy immune system. It's true that a deficiency of vital nutrients can cause poor immune function. But that doesn't mean a person with normal levels of nutrients can expect supplements to improve their immune system.

Can products marketed as immune boosters actually boost immunity? How to get the most out of your immune system It's not a secret and it's not a product.

The best ways to keep your immune system at peak performance are: Eat well and follow a heart-healthy diet, such as the Mediterranean diet. Exercise regularly and maintain a healthy weight. Don't smoke or vape. If you drink alcoholic beverages, drink only in moderation.

Get plenty of sleep. Minimize stress. Get regular medical care, including routine vaccinations. Take measures to prevent infection such as frequent hand washing, avoiding people who might have a contagious illness, and wearing a mask when it's recommended.

The bottom line Perhaps there will come a time when we'll know how to boost immune function beyond following routine health measures. About the Author.

But I think there is still that concern, 'Are people getting enough?

Immune system boosters -

A Cochrane review of randomized controlled trials that examined the effects of taking vitamin C supplements daily on the prevention and treatment of the common cold found that taking the supplement every day didn't reduce the incidence of colds. However, "it did at least reduce the severity and duration of colds," says Dr.

John Mafi , an associate professor of medicine in the Division of General Internal Medicine and Health Services Research at the David Geffen School of Medicine at UCLA.

It's not untrue that vitamin C and vitamin D actually can help to support the function of your immune system. Vitamin D helps your body to create an antimicrobial peptide called cathelicidin, which "stops bacteria, microbes and viruses," and "[regulates] the function of your body's T-cells," Mafi says.

Vitamin D supplements have a bit more evidence for their potential benefits. A systematic review of randomized controlled trials published in the British Medical Journal in found that daily intake of vitamin D supplements protected against acute respiratory infections.

Yet, there are many proven ways to strengthen your immune system outside of supplements like vitamin C and vitamin D, Ben-Aderet says. And if you really want to try vitamin C or vitamin D supplements, Ben-Aderet says: "The jury's still mostly out [on their effectiveness], and vitamin supplementation is cheap and mostly harmless.

If you decide to take vitamin C supplements, you should make sure you don't exceed 2, milligrams of vitamin C in a day, Mafi notes. Too much vitamin C can cause stomach issues like nausea and vomiting and kidney stones, according to Mayo Clinic.

Harvard T. Chan's School of Public Health's hub for nutrition information, The Nutrition Source , recommends a dietary allowance for adults 19 years and older of 90 milligrams for men and 75 milligrams for women. To get vitamin C, you can eat citrus fruits like oranges, grapefruit and lemons, he notes.

Certain greens like kale and broccoli also have great amounts of vitamin C. Taking "roughly to international units IUs of vitamin D per day," is a way to safely address a deficiency, Dr. Jad Sfeir , a Mayo Clinic endocrinologist, told CNBC Make It in August of It's best to find ways to get the vitamin in your diet from foods, Sfeir said, including fortified milk, orange juice or fatty fish like salmon or mackerel.

Having more than 4, IUs per day can increase your risk of toxicity, by greatly elevating the amount of calcium in your bloodstream and urine, Sfeir noted. Sign up for our new newsletter! Get CNBC's free Warren Buffett Guide to Investing , which distills the billionaire's No.

Diabetes, obesity and smoking can also interfere with your immune system and cause it to not work the way it is supposed to, Dr. Because our immune response to fighting disease, infections and viruses in the body is so complex, there's a lot we don't know about why some people have a more balanced immune response while others don't.
