The common cold occurs through a rhinovirus infection of nasal epithelial cells. The rhinovirus is a single-stranded RNA virus that is responsible for most upper respiratory tract infections.

The virus binds to a type of receptor molecule found in the nasal epithelium called intracellular adhesion molecule-1 ICAM Ionic zinc also has an affinity to the ICAM-1 receptor due to its electrical charge.

By attaching to these receptors, Zinc blocks the virus from infecting the epithelial cells. Several other studies have concurred with these results. One study indicated a significant reduction in the severity of the symptoms associated with a cold, as long as zinc is taken within 24 hours of the onset of the symptoms.

Many foods like red onion, berries, elderberry, and green tea contain this important antioxidant. Quercetin has long been revered for its antioxidant potential. Its phenolic properties allow it to neutralize the damage caused by free radicals via the donation of a hydrogen atom.

Recently, scientists have found supplementing with Quercetin may have anti-viral effects. In fact, several in-vitro experiments found Quercetin could inhibit the entry of certain viruses by blocking the receptors on cells to which the viruses enter, and possibly preventing certain infections.

Moreover, certain Quercetin-rich foods like red onion also act as a mucolytic agent, which help to expel stuck mucous and relieve congestion in the lungs. Elderberries are powerful bioflavonoids — naturally occurring compounds that are notorious for their anti-viral and antioxidant properties.

Studies explored the effects of elderberries on immunity and indicated that these berries improve immune function through their ability to increase cytokine activity — signalling molecules that regulate immune responses and inflammation.

The fruit of the elderberry plant is usually sold as a syrup or in dried fruits that can be made into a syrup at home by adding dried elderberries, raw honey and boiling water.

The flower itself can also be consumed as a healthful tea. N-acetyl cysteine NAC is the supplement form of cysteine, a semi-essential amino acid that plays an important role in respiratory and immune function. In addition, NAC has been found to improve respiratory health by helping to break down phlegm and decreasing inflammation in the lungs.

We all know Vitamin D is vital to our well-being. This fat-soluble vitamin plays a fundamental role in the proper functioning of our body and particularly our immune system.

The data regarding the importance of Vitamin D for our health is extensive. Research shows individuals with adequate Vitamin D levels have enhanced immune responses, decreased inflammation and are less prone to infections.

Vitamin D is best absorbed through sun exposure. Twenty minutes a day of sunlight is ideal. However, due to geographical location, many get their vitamin D through daily supplement intake, to prevent a deficiency in this essential vitamin.

Baicalin is a phytonutrient with a long history of use in traditional Chinese medicine for its potent anti-inflammatory compounds and positive effects on the immune and circulatory function. Baicalin is found to strengthen the immune system with its ability to neutralize pathogens.

In vivo studies performed on mice showed oral administration of Baicalin was effective in inhibiting the proliferation of certain viruses, demonstrating the antiviral activity of Baicalin.

Adaptogens help your body cope with stress — be it physical, environmental or emotional. They adapt to the bodies needs at a given time — i. if you are fatigued, they give you energy and help you focus Cordyceps and if you are too wired with anxiety, they calm you down Rhodiola rose a, Reishi.

Their mechanism of action is through supporting and modulating the endocrine and immune system. In fact, Adaptogenic herbs are great for boosting immunity. Herbs like Astragalus, Withania somnifera and Panax ginseng all contain potent immune-protective properties as they help to reduce inflammation.

There is a list of herbs that have been cited in herbal medical literature for their immune-boosting abilities. Some of these include:. Immune network, 13 2 , 70— Padayatty SJ, Katz A, Wang Y, Eck P, Kwon O, Lee JH, Chen S, Corpe C, Dutta A, Dutta SK, Levine M.

Numerous studies reveal that zinc supplements may protect against respiratory tract infections like the common cold 19 , In a study in 64 hospitalized children with acute lower respiratory tract infections ALRIs , taking 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 nigra , which 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 50 , 51 , 52 , 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.

Though he notes that some people have severe, medical vitamin C and vitamin D deficiencies — which can lead to swollen, bleeding gums or bone fractures — and for those individuals, vitamin supplementation is a very effective and necessary measure. 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.
