Key Takeaways

  • Your body needs vital vitamins, micronutrients, and minerals for immune health
  • A weak immune system is an invitation to viral and bacterial infections
  • Supplements like vitamin C and adaptogens are the best immunity boosters

The immune system's primary function is to fight against pathogens like toxins, viruses, and bacteria that invade the body. We require a healthy intake of protein, minerals, micronutrients, and vitamins to strengthen our immune system. Unfortunately, food adulteration, malnutrition, lack of nutrients in the soil, and an unhealthy diet lead to such deficiencies. A weak immune system is an invitation to frequent viral and bacterial infections. It increases other health risks like HIV/AIDS, viral hepatitis, leukemia, and cancer. Some people suffer from immune disorders from birth, while others may develop it later due to environmental and other factors. However, there are certain supplements to boost immune system that can truly help.

Read on to find out the importance of vitamin C, Vitamin D, and other essential vitamins, minerals, and herbs to boost your immunity.

Best Immunity Boosters for Your Health

  • Vitamin C 

Vitamin C is rich in antioxidants and antiviral properties. It is the most popular supplement against infections as it strengthens your immune system. The intake of vitamin C-rich food is effective against oxidative damage and promotes better health. Studies have found that regular intake of vitamin C reduces the occurrence of the common cold significantly in those with high physical stress. Vitamin C can be found in citrus fruits, berries, broccoli, and more.

  • Vitamin D 

Exposure to the sun is the best source of vitamin D. However, those facing vitamin D deficiency can take vitamin supplements to boost immunity. Studies have found that vitamin D enhances your immunity, decreases inflammation, and reduces the risk of infections. In contrast, lower levels of vitamin D increase the risk of respiratory tract infections, including asthma. 

  • B complex vitamins 

Various micronutrients, including B complex vitamins such as vitamin B6 and B12, are vital for your immune health. This was backed by a study that reported that vitamin B6 deficiency impairs immunity. Micronutrient deficiency is a global health issue as it makes you more prone to infections.

  • Elderberry 

Elderberry has been long in use throughout the world because of its antiviral and antioxidant properties. Elderberries improve immunity by increasing cytokine activity responsible for regulating immune responses and inflammation. A study has found that elderberry supplements reduce the duration of colds and symptoms of viral infections

  • Zinc 

Zinc is necessary for bone growth, wound healing, improving eyesight, and boosting your immunity. Researchers found that zinc deficiency is the cause of about 16% of respiratory infections around the globe. Zinc may also reduce the severity of common colds like rhinoviruses and block foreign pathogens from entering the body.

  • Astragalus 

Herbs like astragalus have immune-protective properties that help improve immune responses and reduce inflammation. Astragalus is an herb mostly used in traditional Chinese and Mongolian medicine. In fact, these herbs are one of the best immunity boosters.

  • Selenium 

Infections are often caused due to deficiencies in macro and micro-nutrients, including the trace element selenium. Selenium is effective against viral and bacterial infections, including the viruses responsible for HIV and hepatitis C diseases. Animal studies reported that selenium is an antiviral defense against influenza viruses like H1N1.

  • Adaptogens 

Adaptogens are herbs and roots that support and modulate the endocrine and immune systems. They help you cope with physical, emotional, and environmental stress. For example, if you experience fatigue or anxiety, adaptogens give you needed energy, improve your focus, and help you calm down. They include ashwagandha, holy basil, and ginseng and are still being studied for their stress-relieving and anti-fatigue properties.

  • Other herbs 

Herbs like ginger, garlic, curcumin, thyme, and Echinacea support and strengthen your immune system too. Ginger improves digestion and kills pathogens, while garlic stimulates protective white blood cells. Curcumin has anti-inflammatory properties, whereas thyme is an antimicrobial herb good for your stomach and throat. Finally, echinacea is a source of antivirals, effective against respiratory virus infections.


  • Immune booster tablets 

Apart from natural vitamins and nutrients, multivitamin supplements like Becosules capsules and Neurobion Forte can also help. These capsules are used to prevent or cope with complex vitamin B and C deficiencies.
