Almost 10% of Americans have a nutritional or vitamin deficiency. Without the proper balance of vitamins in your body, you could experience health issues. The vitamins we receive from food and supplements keep our bodies functioning properly.

They also help protect our bodies from illness and invaders. If you develop a deficiency, you could leave your immune system vulnerable.

Here are the five immunity-boosting vitamins you need to stay happy, healthy, and strong. Consider adding these immune system supplements to your routine. These vitamins could protect you from potential disease.

Ready to make a change for the better? Keep reading to discover the five best immune-boosting vitamins today!

1. Vitamin B5

Also known as pantothenic acid, vitamin B5 is a water-soluble vitamin. This vitamin is responsible for making blood cells. It also ensures your body can convert food into energy.

Vitamin B5 is one of the eight B vitamins you can add to your routine. Not every vitamin helps with immunity, though. Some are responsible for your:

  • Digestive tract
  • Skin, hair, and eye health
  • Red blood cells, which carry oxygen
  • Stress- and sex-related hormones
  • Nervous system and liver function
  • Converting fats, carbs, and protein into energy

Vitamin B5 is crucial in creating blood cells that help regulate your immune system. It can also keep bacteria from growing in the body. Adding vitamin B5 to your diet can also improve the circulation of antibodies within your blood.

You need these antibodies to ensure your immune system functions.

Antibodies fight foreign cells. These can include bacterial and viral invaders. In fact, antibodies are the immune system's biggest defensive mechanism.

By helping your body produce antibodies, you can protect your body from disease and infection.

Your body naturally creates antibodies when you have an illness. These antibodies will remain throughout your body until they're needed again. 

How much vitamin B5 you need daily can vary depending on your age.

In addition to taking these vitamins for the immune system, you can also add B5 to your diet. Foods that are rich in B5 include:

  • Vegetables: kale, tomatoes, cauliflower, broccoli, avocado
  • Dairy products: milk, yogurt, milk products, egg yolks
  • Fish: shellfish, lobster, salmon
  • Meat: turkey, beef, pork, chicken
  • Grains: whole-grain bread and cereal
  • Legumes: soybeans, split peas, lentils

Without vitamin B5 in your diet, you could experience hypoglycemia, nausea, irritability, and tiredness. 

2. Vitamin B12

About 1.5% to 15% of the general population has a vitamin B12 deficiency. During your search for the best immune-boosting vitamins, don't neglect B12.

Vitamin B12 is also known as cobalamin. Your body can't produce B12 alone. Instead, you can find it in animal products or vitamins for the immune system. 

Like B5, vitamin B12 plays a part in creating blood cells. Specifically, vitamin B12 produces red blood cells. You need red blood cells to carry oxygen throughout your body.

Vitamin B12 also helps create nerve cells and DNA within your cells. 

Vitamin B12 deficiency could cause a suppression of normal immune responses. Without B12, your immune system could become less efficient.

Your risk of heart disease might increase as a result. 

If you have a low red blood cells count, you could develop anemia. Symptoms include symptoms, fatigue, and shortness of breath. Anemia usually develops when you don't eat a nutrient-rich diet.

Your body might struggle to absorb vitamin B12 as you grow older. Without B12, your immune and nervous systems might become compromised.  

Vitamin B12 is found in milk, eggs, fish, and poultry.

3. Vitamin C

If you're looking for a major immune system booster, don't forget to add vitamin C to the list. Also known as ascorbic acid, vitamin C is water-soluble. It won't stay in your body.

In other words, you need to consume vitamin C daily to reap the benefits.

Consider taking vitamin C with iron to improve absorption. 

Vitamin C helps by supporting healthy tissue growth. It also plays a role in wound healing.

Like vitamins B5 and B12, vitamin C plays a role in your blood. This vitamin can stimulate white blood cell production, which is essential for immunity. Your white blood cells fight off infections.

Without enough vitamin C in the body, you could develop a weakened immune system. You might find you're more susceptible to illnesses as a result. 

In addition to taking immune system supplements, vitamin C is found in citrus fruits, broccoli, tomatoes, and spinach.

4. Vitamin D

Vitamin D enhances your body's pathogen-fighting abilities. It can also boost your immune response while fighting inflammation.

Inflammation is your natural response to illness or invaders. Too much inflammation, however, can cause pain symptoms. Chronic inflammation is associated with conditions like arthritis and diabetes. 

Taking vitamin D supplements could improve your body's response to antiviral treatments. 

Low vitamin D levels, on the other hand, can increase your risk of asthma and tuberculosis. It could increase your risk of contracting viral and bacterial respiratory infections, too.

Vitamin D can promote a healthy immune system. You can take vitamin D supplements for the immune system for your daily dose. Stepping into the sunlight will help your body produce vitamin D, too. 

5. Vitamin E

Vitamin E is an antioxidant. Your body needs antioxidants to fight free radicals. Free radicals are responsible for breaking down and weakening healthy cells.

They might even contribute to cancer and heart disease. 

Free radicals are capable of shortening a cell's lifespan. By taking vitamin E, you could reduce free radical damage. You might slow the cell's aging process as well. 

When taking vitamin E supplements, don't exceed 15mg a day. Too much of any vitamin can cause serious side effects. For example, too much vitamin E can lead to hemorrhagic stroke.

Since vitamin E is fat-soluble, your body can store and use it as needed.
