4 Natural Remedies to Strengthen Your Immune System Function

by Staff Writer

Strengthen Immune System

With so many illnesses threatening to take you down, you need to keep your body in top form.

You’re probably considering immune-boosting medication or going out of your way to stay in good health.

What if we told you that you could keep yourself healthy naturally?

What you eat and how you take care of yourself determine your body’s immunity. Treat yourself to a healthy diet every day and boost your immunity with regular exercise.

You can eat natural foods rich in vitamins, take supplements, exercise, and get enough sleep to stay in good shape.

Note: No single vitamin, supplement, or exercise can cure or protect you from diseases. Combine them with a healthy diet and use recommended vaccines to safeguard your body from illnesses.

So, how can you boost your immune system naturally?

1. EAT FOODS THAT ARE RICH IN VITAMIN C AND ANTIOXIDANTS

One sure way to boost your immune system is by eating foods rich in vitamin C and antioxidants.

Vitamin C helps your body make more white blood cells—the disease-fighting agents in your system. It also helps in improving your overall body function.

CITRUS FRUITS

When you become sick with the common cold or flu, the most natural way to treat it is to eat citrus fruits.

They don’t have any medicinal value, but they do help your body produce disease-fighting white blood cells.

With a vitamin C boost, your white blood cells can fight off minor bacterial infections without the need to take prescribed medication.

Citrus fruits and colorful fruits rich in vitamin C include:

  • Grapefruit
  • Lemon
  • Lime
  • Oranges
  • Tangerines
  • Clementines

Note: Your body cannot store vitamin C. Eat a citrus fruit every day to maintain a helpful dose of the vitamin for a better immune response system.

RED BELL PEPPERS

If you thought that citrus fruits were your safest source of vitamin C, you’re wrong.

Red bell peppers have three times more vitamin C than fruits and are better at boosting your immune system.

Strengthen Immune System

They’re also an excellent source of beta carotene, which gets converted to vitamin A in your body. Vitamin A helps to keep your skin and eyes healthy.

Include bell peppers and vegetables in your diet as a natural way of boosting your body’s immunity.

SPINACH

Did you know that spinach is one of the best sources of antioxidants for your body?

Antioxidants help to neutralize oxidized molecules in humans and soothe inflammation and soreness. Oxidation is caused by free radicals in your body and can slow down your body’s processes.

Strengthen Immune System

Spinach is also an excellent source of vitamin C and beta carotene.

The benefits of spinach and most other vegetables are highest when cooked as little as possible.

NUTS

Nuts are a great source of vitamin E—another strong antioxidant. They also have healthy fats, which help you to keep a great immune system.

The average adult needs at least 15 mg of vitamin E each day, which translates to 46 whole-shelled almonds.

Strengthen Immune System

You can also boost your immune system with other foods such as broccoli and sunflower seeds.

YOGURT

One way to fight illness-causing bacteria in your body is to eat (or drink) yogurt.

Yogurt has live and active cultures and beneficial bacteria which work to improve your overall health.

Strengthen Immune System

Use plain yogurt as opposed to the flavored and sweetened ones. You can sweeten and flavor yours with berries and honey if you prefer. You’ll be adding flavor and get health benefits at the same time.

Yogurt is also a great source of vitamin D and one of the foods that scientists are studying as an effective way of boosting your immune system to deal with certain illnesses.

Bonus: Here’s a fact sheet on the vitamins your body needs and their natural sources.

VITAMIN NATURAL SOURCE
Vitamin A Eggs, milk, carrots, sweet potatoes, cantaloupe
Vitamin B1 Milk and milk products, green leafy vegetables, whole grains
Vitamin B12 Meat, poultry, fish, seafood, eggs
Vitamin B3 Meat, poultry, fish, whole grains
Vitamin B6 Meat, poultry, vegetables, fruits
Vitamin C Oranges, strawberries, tomatoes, kiwi, broccoli, red and green bell peppers
Vitamin D Egg yolks, liver, fatty fish, fortified milk
Vitamin E Avocados, nuts, seeds, green vegetables, whole grains
Vitamin K Green leafy vegetables such as spinach and kales

2. USE NATURAL SUPPLEMENTS TO SUPPORT OPTIMAL IMMUNE FUNCTION

Boosting your immune response might take more than eating a healthy diet. You can help by taking supplements in natural foods.

Note: Natural supplements aren’t quick fixes for your immune system. They work overtime and help your body stay in tip-top shape.

A few well-chosen immune-support supplements might be just what you need to round out a healthy diet.

VITAMIN D SUPPLEMENTS FOR STRONG IMMUNE CELLS

Vitamin D strengthens your infection-fighting pathogens such as monocytes and macrophages and leaves your body better prepared to fight infections.

It also helps to decrease inflammation and soreness in your muscles. Some natural sources of vitamin D are:

  • Cod liver oil
  • Salmon
  • Swordfish
  • Orange juice fortified with vitamin D
  • Beef liver

ZINC TO SUPPORT A HEALTHY IMMUNE SYSTEM

Zinc is one of the most important drivers in your immune system function.

When you have an inflammation, zinc helps in cell development and communication to soothe and reduce the inflammation.

It also protects your body tissues from wear and tear and blocks foreign pathogens. Some of the natural zinc supplements are:

  • Meat
  • Shellfish
  • Legumes
  • Dairy
  • Eggs
  • Whole grains

ORGANIC ELDERBERRY TO BOOST IMMUNE FUNCTIONS AND STRENGTHEN OVERALL HEALTH

Elderberry supplements have antibacterial and antiviral qualities to help your body fight against disease-causing pathogens.

They help to combat bacterial infections in the respiratory tract and some strains of the influenza virus.

The supplements boost your immune system and shorten the duration of common cold and viral infections.

More research is underway on how elderberries can further strengthen your immune system.

3. EXERCISE REGULARLY

You can also boost your immune system with regular intensive and moderate exercise.

You don’t need to break your bank to get the health benefits of regular exercise.

It’s easy to do some of the most helpful exercises in the comfort of your home or take a simple walk or jog in the park.

Regular exercise can help minimize stress, manage chronic diseases such as heart disease, and improve overall immune function.

Here are some exercises you can include to help boost your immunity.

STRENGTH TRAINING

Weight lifting and muscle training exercises are about more than just a well-toned body.

When you lift weights, your body releases health-promoting compounds. Your blood flows better and boosts functioning in your organs.

Proper blood flow helps to relieve chronic stress and gives your body a chance at better performance.

Examples of strength training exercises include:

  • Weight lifting
  • Cycling
  • Exercising with resistance bands
  • Dancing

HIGH-INTENSITY INTERVAL TRAINING

High-intensity interval training, known as HIIT for short, pushes you to your limits and out of your comfort zone.

Strengthen Immune System

HIIT training consists of short bursts of intense exercise followed by intervals of lower intensity exercise or complete rest between each burst.

During bursts, participants should be working at their max capacity.

HIIT can often be a mix or aerobic and resistance training.

    WALKING

    Walking in the park or around the neighborhood every day could be the simple exercise you need to boost your immune system.

    It helps increase the number of white blood cells in your blood and fortifies your body’s defense against the common cold, flu, and other illnesses.

    Make it a habit to take brisk walks regularly and watch your body's immune system improve gradually.

    It’s also a great way to lower blood pressure.

    4. GET ADEQUATE SLEEP

    You read that right.

    Getting quality sleep is one of the simplest and most natural ways of achieving a strong immune system.

    When you sleep, your body releases proteins called cytokines. They help you fight against infections and inflammations.

    Inadequate sleep means that you're likely running low on cytokines and exposing yourself to infections and illnesses.

    Most adults’ immune systems work well with between 6–8 hours of sleep every day. This should be your daily target.

    BOTTOM LINE

    Your body’s immune response is the one thing that you should attend to constantly.

    It can’t fight diseases and infections if the immune response is weak. Boosting it doesn’t have to be a costly and artificial affair.

    You can easily use natural foods and supplements to improve your immune system. Your healthcare practitioner can provide medical advice on the best supplements to use.
