Best Vitamins and Minerals to Boost Immunity

21 September 2023

In the modern era, we consume a lot of tasty and yummy foods but we get sick often due to weak immunity. This reason is, that our foods lack immune-boosting nutrients to fight off infections. Immune-boosting nutrients include vitamins and minerals. 

Vitamins and minerals are essential nutrients that play various physiological functions in the body. The most important function of vitamins is boosting your immune system. Vitamins that boost your immune system include Vitamin A, Vitamin D, Vitamin C, Vitamin E, vitamin B complex, and carotenes. They enhance the production of soldiers of the body called white blood cells (mainly B cells and T cells) to fight off foreign invaders. They play a critical role in initiating innate as well as adaptive immune responses of the body. 

This blog lists essential vitamins and minerals, their sources, and natural ways to boost your immunity. Let’s get straight into it without wasting a second! 

Vitamins And Minerals That Boost Up Immune System:

Vitamins and minerals that boost the immune system include Vitamin A, D, C, E, and B complex, Zinc, and Selenium. Vitamin E, C, and some members of the vitamin B complex act non-specifically by acting as antioxidants in the body. However, vitamins A and D act directly on the immune system and are considered to be the most important vitamins for the immune system. 

Consuming foods rich in vitamins and other nutrients, like eggs, legumes, fruits, yogurt, seafood, nuts, fish, dairy products, liver, leafy green vegetables, and green tea, have a key role in boosting your immune system. If you consume a diet that lacks essential nutrients and vitamins, it is a gateway to various diseases. Your immune system will not work properly, and your body will become susceptible to various pathogens.

Here’s a list of vitamins and minerals to boost your immune system: 

1-Vitamin A: 

Vitamin A is a fat-soluble vitamin. It is absorbed as retinol from the diet and is metabolized to various metabolites, including retinyl esters, retinol, retinoids, and retinoic acid. These metabolites have a key role in boosting your immune system. 

You may wonder how Vitamin A boosts immunity; here is the beneficial role of vitamin A in immunity: 

  • Retinoic acid kills harmful cells in your body and promotes the growth of white blood cells which are important components of your immunity.
  • Retinoic acid promotes Helper T cell differentiation in the gut. Helper T cells are white blood cells that play a critical role in long-term immunity. 
  • Retinoic acid inhibits the premature death of white blood cells. 
  • Vitamin A metabolites keep TH1 and TH2 cells balanced. Its deficiency causes TH2 cell deficiency. 
  • Vitamin A has an important role in the maintenance of epithelial tissue and mucosal membranes that constitute the first line of defense against pathogens. 
  • Vitamin A has a role in cell differentiation, maturity, and immunological function in your body’s innate (inborn) immunity. 

Sources: Vitamin A is present in Eggs, carrots, spinach, leafy green vegetables, nuts, fish, dairy products, liver, and fresh fruits.

Vitamin D:

Vitamin D is also a fat-soluble vitamin, and it acts directly on your immune system. It is directly synthesized by your skin in sunlight. Different forms of Vitamin D act differently on your immune system.

Calcitriol, or 1,25 dihydroxy vitamin D, is an active form of vitamin D. It generates an innate and adaptive immune response. Moreover, it maintains membrane stability, which is the first line of defense against pathogens.

1,25 dihydroxy vitamin D has anti-inflammatory effects, which help fight off infections. Moreover, Vitamin D initiates the differentiation of various cells like macrophages (a type of white blood cell that engulfs microorganisms). 

Vitamin D deficiency is associated with various infections and autoimmune diseases like diabetes and multiple sclerosis. 

Sources: Eggs, fish, cheese, liver oil, beans, milk, nuts, mushrooms, and tuna are rich in vitamin D. 

Vitamin C:

Vitamin C acts non specifically by acting as an antioxidant in the body. It supports innate as well as adaptive immune responses in the body. Antioxidants destroy free radicals. Free radicals are charged ions that destroy your body cells. Vitamins and minerals are protective against these free radicals.

As vitamin C has anti-inflammatory effects, it protects your body from inflammation and cell injury. According to research, vitamin C deficiency is the fourth leading nutrient deficiency in the United States, which leads to various diseases. Consuming a diet rich in Vitamin C can overcome this deficiency. 

Sources: Sources of vitamin C include citrus fruits, oranges, broccoli, kiwi fruit, strawberries, and bell peppers.

Vitamin B is important for a healthy balance of the immune system. Among vitamin B are niacin, thiamine, riboflavin, cobalamin, folic acid, and pyridoxine. Different forms of vitamin B complex act as antioxidants. They protect your body from ischemic injury and cardiovascular illness like cardiac failure. 

Folic acid and cobalamin (vitamin B12) have an important role in the synthesis of DNA and other nucleotides. They have a role in proteins and antibody production that are a part of your immune system. 

Vitamin B5 is involved in the healing process of cuts and wounds. According to a study, a daily intake of 5mg of folic acid boosts immunity.

Sources Of Vitamin B: 

Vitamin B is available in various forms. You can fulfill vitamin B requirements by taking vitamin B-rich foods. The following are different sources of vitamin B: 

Thiamine: Common sources of thiamine include grains, bread, cereals, pasta, fish, soybeans, legumes, and nuts.

Riboflavin: You can get riboflavin from foods like eggs, meat, oats, spinach, bread, grain products, kidney, and mushrooms. 

Niacin: Poultry, legumes, beef, nuts, potatoes, avocados, and cereals are rich in niacin, so you should consume them in your diet for enough thiamine.

Pyridoxine: Pyridoxine is found in fish, meat, starchy food, and potatoes. 

Folic Acid: Liver, vegetables, dark green vegetables, peas, meat, beans, and fruit juices are rich in folic acid. 


Zinc is a micronutrient that boosts your immunity. It is important for the development and function of cells needed in innate immunity, natural killer cells, and neutrophils. Moreover, Zinc deficiency affects macrophages, phagocytosis, and cytokines production. Zinc also acts as a cofactor for various reactions influencing the immune system. 

Research shows that Zinc-deficient patients face an increased susceptibility to various diseases like skin problems, hair loss, muscle impairment, and memory loss. 

Sources: Some common sources of Zinc include oysters, pumpkin seeds, eggs, legumes, fruits, yogurt, seafood, nuts, and meat.


Selenium is a micronutrient and has a role in regulating the immune system. It acts as a regulator of the immune system and protects from oxidative stress. It also boosts the immune system to fight against cancer cells. Selenium initiates, regulates, and boosts the immune response.  

Sources: Eggs, legumes, Brazil nuts, brown rice, bread, meat, cereals, pasta, shrimp, and mushrooms are rich in selenium.

Natural Ways To Boost Immunity: 

If you want to boost your immune system, you can choose various natural ways to do so.  These include dietary modifications and lifestyle changes to boost your immune system.  A healthy lifestyle, a nutrient-rich diet, proper sleep, exercise, food supplementation with vitamins, and managing stress levels are effective ways to boost your immunity naturally. 

The following are the natural ways to naturally boost the immune system:

Moreover, they have anti-inflammatory effects on the body.

3. Exercise:

Engage yourself in moderate exercise. It will boost your immunity by regenerating immune cells and reducing inflammation. Studies have shown that vigorous exercise depresses your immunity while moderate daily exercise enhances the effectiveness of vaccines on your body. 

Maintaining a healthy weight is also essential for proper immune system functioning because obesity affects your immune system. Exercise is an effective strategy to maintain a healthy weight. 

4. Manage Stress Levels:

Stress is one of the major factors that affects your immune system. Long-term stress promotes inflammation and immune disturbances. You can opt for strategies like meditation, yoga, mindfulness, breathing exercises, muscle relaxation exercises, and jogging to reduce stress.

5. Stay Hydrated:

Hydration does not directly affect your immune system, but dehydration can lead to heart problems, kidney problems, mood changes, problematic digestion, and loss of focus. These complications increase susceptibility to infections. Drink adequate water to stay healthy. 

6. Limit Sugar:

If you consume too much sugar and carbohydrates in your food, it will make you obese, and obesity is a gateway to various diseases, including heart disease and diabetes. Limiting sugar and carbohydrates protects you from getting cardiovascular illness and diabetes. Ultimately, it protects your body from a lot of complications and boosts your immunity.
