Keeping your immune system healthy is key to preventing infection and disease. Making healthy lifestyle choices by consuming nutritious foods and getting enough sleep and exercise are the most important ways to boost immune system. However, note that some supplements can interact with prescription or over-the-counter medications you’re taking. Some may not be appropriate for people with certain health conditions. Be sure to talk with your healthcare provider before starting any supplements.
1. boost immune system with Vitamin D
Vitamin D enhances the pathogen-fighting effects of monocytes and macrophages — white blood cells that are important parts of your immune defense — and decreases inflammation, which helps promote immune Response. Many people are deficient in this important vitamin, which may negatively affect immune function. In fact, low vitamin D levels are associated with an increased risk of upper respiratory tract infections, including influenza and allergic Asthma. Some studies show that supplementing with vitamin D may improve immune response. In fact, recent research suggests that taking this vitamin may protect against respiratory tract infections.
In a 2019 review of randomized control studies in 11,321 people, supplementing with vitamin D significantly decreased the risk of respiratory infections in people deficient in this vitamin and lowered infection risk in those with adequate vitamin D levels. This suggests an overall protective effect. Other studies note that vitamin D supplements may improve response to antiviral treatments in people with certain infections, including hepatitis C and HIV.
Zinc is a mineral that’s commonly added to supplements and other healthcare products like lozenges that are meant to boost your immune system. This is because zinc is essential for an boost immune system function. Zinc is needed for immune cell development and communication and plays an important role in inflammatory response. Zinc deficiency affects around 2 billion people worldwide and is very common in older adults. In a 2019 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.
3. boost immune system with Vitamin C
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. Oxidative stress can negatively affect immune health and is linked to numerous diseases.
4. boost immune system with Elderberry
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.

5. Medicinal mushrooms
Many types of medicinal mushrooms have been studied for their immune-boosting potential. 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. Turkey tail is another medicinal mushroom that has powerful effects on immune health. Research in humans indicates that turkey tails may enhance immune response, especially in people with certain types of cancer. Many other medicinal mushrooms have been studied for their beneficial effects on immune health as well.
- Astragalus. Animal research suggests that its extract may significantly improve immune-related responses.
- Selenium. Selenium is a mineral that’s essential for immune health. Animal research demonstrates that selenium supplements may enhance antiviral defense against influenza strains, including H1N1.
- Garlic. Garlic has powerful anti-inflammatory and antiviral properties.
- Andrographis. This herb contains andrographolide, a terpenoid compound found to have antiviral effects against respiratory-disease-causing viruses, including enterovirus D68 and influenza A.
- Licorice. Licorice contains many substances, including glycyrrhizin, that may help protect against viral infections. According to test-tube research, glycyrrhizin exhibits antiviral activity against severe acute respiratory-syndrome-related coronavirus (SARS-CoV).
