10 Best Vitamins & Supplements To Boost Your Immune System

Boost your immune system with vitamins and supplements available over the counter. 

How can your immune system be strengthened? By and large, your immune system does an outstanding job of protecting you from disease-causing microorganisms. However, there are times when our immune system fails; it is when a germ successfully invades and makes you sick. Is it possible to intervene and boost your immune system during this process? What if your diet were improved? Are you taking specific immune system vitamins or herbal preparations? Are supplements to boost immune system effective? Or making additional lifestyle changes in the hope of bringing about a near-perfect immune response?

What can you do to boost your immune system?

While the concept of boosting one’s immunity is appealing, the ability to do so has been proven difficult for various reasons. The immune system is a system, not a single entity, so it requires balance and harmony to function properly. There is still much that researchers do not understand about the immune response’s complexities and interconnectedness. There are currently no scientifically established direct links between lifestyle factors and improved immune function.

However, this does not negate the fact that the effects of lifestyle on the immune system are intriguing and warrant further investigation. The results of diet, exercise, age, psychological stress, and other factors on the immune response are being studied in both animals and humans. Meanwhile, general healthy-living strategies make sense, as they are likely to benefit immune function and provide additional proven health benefits.

How to strengthen the immune system with a healthy lifestyle?

Your first line of defense should be to maintain an active and healthy lifestyle. Following general health guidelines is the single most effective way to maintain a functional immune system naturally. Every part of your body, including your immune system, works better when you protect it from environmental assaults and supplement it with healthy-living strategies such as the following:

  • Avoid smoking.
  • Consume lots of fruits and vegetables.
  • Exercise on a regular basis.
  • Maintain a healthy weight.
  • If you drink alcohol, do so in moderation.
  • Get enough sleep.
  • Take precautions to avoid infection, such as frequently washing your hands and thoroughly cooking meats.
  • Make an attempt to minimize stress.
  • Maintain current vaccinations. Vaccines prime strengthen your immune system to combat infection before it establishes a hold in your body.

What are some vitamins that can help strengthen your immunity?

Since COVID-19 symptoms are similar to those of a cold or flu, Vitamins B, C, and D, as well as Zinc, may be beneficial in boosting your immune system and fighting the illness in the same way that they can help you recover from a cold or flu.

1. Vitamin C

Vitamin C can generally help you fight off a cold faster or alleviate cold symptoms if you take it prior to becoming ill. In addition, as an antioxidant, it can aid in the reduction of inflammation—and lung inflammation is a severe symptom of COVID-19, which can result in respiratory distress or death. Therefore, if you are still in good health, it is not too late to begin taking vitamin C now.

2. Vitamin D

Vitamin D’s primary function is to assist your body in maintaining optimal blood calcium and phosphorous levels, which you can obtain through exposure to the sun’s ultraviolet rays, supplements, and the foods you eat.

Consuming an adequate amount of vitamin D can also help protect you against respiratory infections. According to clinical studies published in the Journal of Pharmacology and Pharmacotherapeutics, vitamin D supplementation significantly reduces the risk of respiratory tract infections.

3. B Complex vitamins

Vitamin B6 is critical for maintaining a healthy immune system. As a supplement, include vitamin B in your daily diet (you can easily obtain your daily requirement from fortified cereals), or you can simply take a multivitamin.

4. Zinc

Taking a zinc throat lozenge or an over-the-counter cold remedy containing zinc (like a syrup or tablet) can help reduce the duration of rhinovirus colds. Additionally, zinc aids in the resolution of symptoms – such as nasal congestion, nasal drainage, sore throat, and cough.

It has also been shown to aid in the production and activation of T cells (t-lymphocytes), which are responsible for the body’s response to infections, according to the National Institutes of Health.

Start taking zinc to treat your illness within the first 24 hours of symptoms for a faster recovery. A proper dose of zinc is 75 mg, but be cautious since exceeding 150mg of zinc per day may cause zinc toxicity and harm your immune system.

Consult your doctor if you are taking more than one zinc medication to avoid adverse reactions.

What are the best immune system supplements to take?

Whether consumed whole or in tablet form, the following immune system supplements may assist in maintaining your health and your immune system’s readiness to fight coronavirus – or any virus or diseases for that matter. 

5. Astragalus

Astragalus is a herb whose root is utilized in medicine. It is typically used to boost the immune system and cure common colds, upper respiratory infections, seasonal allergies, and swine flu. Additionally, it is used to fight germs and viruses.

Although there is limited study on its usefulness against disease, 160 mg of astragalus root extract taken by mouth daily for 3-6 weeks was found to relieve symptoms such as runny nose, itching, and sneezing.

6. Selenium

Selenium is a mineral that has several uses, including the prevention of bird and swine flu. In addition, it is a strong antioxidant that has been shown to improve immunological function, except in patients with autoimmune illnesses, where it may have a detrimental effect on the immune system.

7. Garlic 

Garlic’s antiviral qualities may help alleviate the intensity of symptoms associated with colds, influenza, and COVID-19 infections.

During the cold season, participants who took garlic supplements caught fewer colds than those who received dummy pills, according to one study. Moreover, garlic may also help to alleviate the symptoms of a cold. While it can be eaten raw, it can also be taken as a supplement.

8. Licorice root

According to a 2009 study published in the journal Anesthesia & Analgesia, licorice root may be used as a gargle to relieve the pain of a sore throat, a frequent symptom of coronavirus. Additionally, licorice root has been shown to help ease congestion and inflammation. You can chew licorice root or consume it as tea at the same time.

9. Echinacea

Echinacea has been used to alleviate cold symptoms at the onset of sickness, although data on its efficacy is inconsistent. According to some studies, consuming echinacea can reduce the chance of contracting a cold by up to 58%. However, the additional study indicates that ingesting echinacea does not protect against the common cold when exposed to cold viruses.

Early research indicates that taking a specific echinacea product (such as Monoselect Echinacea, Pontenure, PharmExtracta, Italy) daily for 15 days may improve the response to the flu vaccine in people with respiratory problems such as bronchitis or asthma. By doing this, they can decrease their risk of developing COVID-19 complications.

In a 2009 study, echinacea and sage were found to relieve the pain of a sore throat when combined as a throat spray with antibacterial and antiseptic sage.

10. Propolis

Propolis, a resinous substance extracted from the buds of poplar and cone-bearing trees, is used to strengthen the immune system and as an antioxidant and anti-inflammatory agent. It may help prevent or shorten the duration of common colds and other upper respiratory tract infections, according to some data.

What are the signs that you have a weakened immune system?

If you’ve found that you’re frequently unwell, tired, or have other nagging symptoms that you’re unable to explain, it may indicate that your immune system is weakened. Take a look at these warning signs so you can boost your immune system immediately.

1. High Level of Stress

It is not coincidental that you become ill following a large assignment at school or work or after an emotional incident. As per a report by the American Psychological Association, chronic stress impairs your immune system’s responses.

2. Frequent Colds

Adults are entirely used to sneezing and sniffling their way through two or three colds per year. This is because the majority of people recover within seven to ten days. However, if you are frequently contracting colds or have a cold that refuses to go away, this is a strong indication that your immune system is fighting to keep up.

3. Tummy Issues

If you experience frequent gas, diarrhea, or constipation, this could indicate a weakened immune system.

Nearly 70% of your immune system is found in your digestive tract, according to research. Beneficial bacteria and germs that thrive there protect your stomach from illness and help your immune system function properly.

Inadequate levels of these beneficial gut bacteria can put you at risk of infection, persistent inflammation, and potentially autoimmune diseases.

4. Slow Wound Healing

After a burn, cut, or scrape, your skin goes into damage-control mode. Your body protects the wound by directing nutrient-rich blood to the area to aid in regenerating new skin.

This healing process is contingent upon the presence of healthy immune cells. However, if your immune system is weakened, your skin will be unable to heal. Therefore, your wounds linger and you have a difficult time healing.

5. Frequent Infections

If you frequently struggle with infections, your immune system may be sending you warning signs.

According to the American Academy of Allergy Asthma & Immunology, symptoms of a potential immunological deficit in adults within a year include the following: 

  • Experiencing more than four ear infections 
  • Two episodes of pneumonia 
  • More than three episodes of bacterial sinusitis or chronic sinusitis 
  • Often in need of more than two courses of antibiotics 

6. Unusual Tiredness

You are well aware that burning the candle at both ends would inevitably leave you feeling drained. However, if you’re receiving adequate sleep and still experiencing weariness, it’s worth exploring whether your immune system is communicating with you. Remember that when your immune system is compromised, your energy level suffers as well.
