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supplements significantly reduced upper respiratory symptoms caused by viral infections However, this study is outdated and was sponsored by the elderberry syrup manufacturer, which may have skewed results Though it has been suggested that elderberry can help relieve symptoms of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.

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.

Vaccines Basics Testing Symptoms. Nutrition Evidence Based The 15 Best Supplements to Boost Your Immune System Right Now. Medically reviewed by Sade Meeks, MS, RD , Nutrition — By Jillian Kubala, MS, RD — Updated on February 1, Below are the four supplements that I take every day and often recommend to my patients.
Trust me: Your body will thank you. Since humans cannot manufacture vitamin C and it's not stored it in the body, it needs to be constantly replenished. Vitamin C is a powerful antioxidant, anti-inflammatory and strengthens our immune system cells.
It gets used up rapidly during infection and when we are under tremendous stress. It also speeds wound-healing and is great for your skin. Supplemental vitamin C has been found in studies to lower the severity and duration of a cold, and in early studies may lessen the severity of hospitalized Covid patients' symptoms.
Vitamin D deficiency is a worldwide issue, which is a problem because this superstar vitamin modulates so many aspects of our immune function. It makes our innate immune system more efficient in killing bacteria and viruses, and can reduce the frequency of upper respiratory infections.
Low vitamin D has also been correlated with a higher incidence of autoimmune disease like multiple sclerosis. Because vitamin D isn't found readily in many foods save for fatty fish, cod liver and fortified foods , most people benefit from vitamin supplementation, especially in the winter months or if they don't spend much time outdoors on a regular basis.
Zinc is a trace mineral with crucial effects on the effectiveness of the cells and cytokines of our innate and adaptive immune systems. Zinc aids in fighting viruses, protects us from free radical damage to our cells, and has been shown to shorten the duration of a cold when given as a supplement.
Zinc is found at high levels in oysters, beef and crab, and in lower amounts in legumes, tofu, pumpkin seeds, cashews and other nuts and seeds. I recommend adding in 15 to 30 milligrams of zinc daily, especially during the fall and winter months and at the first signs of cold or flu.
This substance is the main active ingredient in turmeric root and has been shown to bestow multiple health benefits. In fact, there are more than human clinical trials showing the effectiveness of curcumin in treating diseases ranging from autoimmunity to Alzheimer's disease. The magic of curcumin is how it decreases inflammation at multiple levels in the body, not only helping with symptom relief from pain and arthritis but also blocking inflammatory cytokines driving autoimmune disease, heart disease and diabetes.
It also improves the health of our gut bacteria , which adds to our overall immune health. Because curcumin is not absorbed well and one would have to eat copious amounts of turmeric root to have significant benefits, I recommend supplementing with 1, milligrams per day with food.
