Best Immune System Boosters: Prevent Cold & Flu with Vitamins + Antioxidant Defense
Your immune system is critical for ensuring your survival; it serves as the first line of defense against diseases, bacteria, and other viruses that may create damage in your body. It is an intricate system that identifies and destroys abnormal cells, clearing your body of any pathogens to keep your body in a state of homeostasis. Basically, it’s always on alert to keep you healthy.
There are many immune boosters present in the foods you eat, and if you’re not keeping a watchful eye on all the ingredients in your daily meals, you may be deficient when it comes to the vital nutrients and vitamins your body needs to ward off illness.

Below, we list what we took into consideration when putting this top five list together.

Consumer reviews and comments detail personal experiences, which provide us with a look into their experiences with the immune boosting products.

We only chose products with reviews and comments that are overwhelmingly positive.

How well each brand describes their products is of paramount importance. As a consumer, you should understand why the product was created, what ingredients it contains, and how each of those ingredients supports your immune system. We look for transparency in this area.

Enjoy an array of botanical extracts in VitaPost’s Immune Support dietary supplement to gain the nourishment your immune system deserves.

Vitamin E is a strong antioxidant that works alongside your immune system to keep your system thriving, no matter your age. Green tea extract is also a powerful antioxidant that supports your immune system function while boosting your body’s other antioxidants as well.
- Beta-Glucans and Graviola Leaf
Beta-glucans are the harmless sugar-chains that occur naturally in fungi and bacteria. Since the body recognizes these as pathogenic, it is able to build resistance to beta-glucans when they are introduced into the body. This is how beta-glucans work to support your immune system. The Graviola leaf is also known to support your immune system, so you get double the support with these two ingredients.

Turmeric and ginger are a complementary match of two roots that create the ideal superfood blend. Not only do turmeric and ginger support a healthy immune system, but they also support joint health. This product contains three primary ingredients, including:
The root of turmeric has gained massive popularity all over the globe, due to its reputation for assisting with respiratory system health, joint health, and even alertness. It is a well-known part of the Ayurvedic tradition for all its healing and health-boosting properties.
Ginger is another superfood often used by those who are health conscious. It brings comfort to upset stomachs and supports joint health, all with a distinctive, alluring flavor enjoyed by many.
BioPerine® refers to the extract of peppercorn and long pepper and is a patented formulation. The chemical name for this extract is piperine, and you’re probably familiar with the taste of this pepper, as you likely incorporate it into many of your home-prepared meals. Piperidine is known for its ability to enhance absorption of some nutrients, particularly curcumin. It makes turmeric that much more powerful.
Turmeric is commonly used because of its beneficial effects, but unfortunately, its absorption rate can be low on most occasions. That’s why BioPerine® is such an essential addition to this formula; it ensures you’re getting more of the benefits associated with turmeric. Ginger, often consumed within beverages, offers massive relief if you’re experiencing digestive comfort. It’s a welcome superfood in any household. In addition, it supports your immune system to aid with your overall well being.

- Steady, All-Day Energy

With Mushroom Defense, you experience more mental clarity, which means you can focus for longer periods and your memory is improved.
- Boosted Immune System
Mushroom Defense is a mushroom complex that gives your immune system a gentle helping hand. This is especially helpful if you suffer from seasonal allergies, as your immune system hops into overdrive to protect you against allergenic invaders. While allergies are your immune system’s natural response to fighting against pollen, with a boosted immune system, your reactions to allergens are not nearly as severe.
What are Immune Boosters?
Immune boosters are foods and supplements that keep your immune system in top shape, saving you from frequent colds, keeping you healthy during flu season, and helping you ward off infections. Below, we list a couple of well-known immune boosters:
Garlic is a welcome ingredient in most dishes and it’s one of the most beneficial foods to add to your regular diet to keep you in good health. Garlic is known to not only combat infections, but it is also helpful in slowing down the hardening of your arteries and boosting your immune system to keep you in a state of wellness.
- Red Bell Pepper
Red bell peppers are packed with Vitamin C and are a rich source of beta carotene, which is an antioxidant that supports cognition. Beyond serving your immune system, red bell peppers also help you maintain healthy skin.
- Citrus Fruits
Vitamin C is known to strengthen your immune system, and it’s why many flock to it at the first sign of a cold. Vitamin C powers up white blood cells, which keep your body in the fight against any kind of infection. Since your body doesn’t produce vitamin C on its own, you need the daily boost to keep your immune function in great shape.
Ginger is another common go-to following illness. It helps to decrease inflammation and soothes sore throats and nausea. It has additional benefits, like lowering cholesterol and helping to alleviate chronic pain.
Spinach is also rich in vitamin C and it is filled to the brim with antioxidants and beta carotene, which keep your immune system ready to fight any infection that tries to take hold inside your body.
Turmeric is known for its delightful, yellow color and it is often used in dishes for its anti-inflammatory properties. It is also rich in curcumin, which boosts your immune system and has anti-viral properties.
- Green Tea
Green tea is known for its antioxidants and works to increase immune function.
Papaya, like citrus fruits and spinach, is a powerhouse fruit loaded with vitamin C. It also has anti-inflammatory properties to benefit your overall health.
Natural Immune Boosters
Your immune system helps with regulating your body and it’s designed to ward off illnesses and diseases. There are several methods for boosting your immune system naturally, and each is easy to incorporate into your regular schedule. Ensure you are incorporating all of the following into your daily routine to keep your immune system functioning optimally:
Enjoy Nutrient-Dense Foods
Maintain a balanced, healthy diet to boost your immune system. Eat whole foods like vegetables, fruits, and meats, to enjoy the benefits of the nutrients they offer. You should also incorporate healthy omega-3 fatty acids, which can be found in avocados and eggs. Not only does a well-balanced diet keep your immune system functioning well, but it also keeps you in a healthy weight range, which is optimal for good long-term health.
Always Stay Hydrated
When you make sure you’re always well hydrated, you are giving your body the immune system support it needs. Skip the sugary drinks and opt for water instead. Drinking plenty of water helps with your digestive system and supports all of your body’s regular functions.
To keep your immune system healthy, you should be prioritizing exercise. Choose a moderate intensity for your workouts; the point is to get your heart rate up on a regular basis. Don’t overdo it, especially when you’re already feeling something coming on, because if you overexert yourself while your immune system is fighting off illness, you could lower your immune response.
Your body needs a good sleep schedule with deep rest to function optimally. Try to maintain the same bedtime and the same wakeup time, even on your days off. This allows your body to regenerate overnight, so you wake feeling rejuvenated. Your immune system benefits from your sleep cycles, so don’t skimp on your rest.
Supplement with Vitamins
Vitamins are helpful immune boosters that complement the nutrients you receive from the whole foods you consume. Keep your diet clean, with a balanced number of fruits, vegetables, proteins, and healthy fats, and supplement with vitamins and other superfoods to keep your body going strong.
What Weakens the Immune System?
Just as there are ways to boost your immune system, there are actions you take that could cause the complete opposite effect and leave you vulnerable to illnesses and diseases. Avoid the following to keep your immune system healthy.
Excessive Sugar Intake
If you have a sweet tooth, you must be mindful not to overdo it. Sugar is addictive and it can be tough to say no to your favorite decadent desserts. But when your sugar spikes, your immune system is suppressed. And when your immune system is suppressed, you are more likely to catch a cold or flu virus.
Poor Diet Choices
Above we discussed the importance of incorporating whole, nutrient-dense foods into your diet. Cheeseburgers and pizza, though easy to get and often delicious going down, just don’t cut it. Avoid foods with poor nutritional value and stock your refrigerator with all the good stuff so when a craving hits, you can make a good choice that supports your immune health.
Excessive Alcohol Consumption
You may love a good happy hour out with friends or co-workers, but excessive alcohol consumption is also a culprit that weakens your immune system. Limit your alcohol intake to keep your body at its peak.
Exercise is an important component of any healthy lifestyle. You may not have control over certain portions of your day if you work behind a desk; however, you should incorporate movement during your lunch breaks and after work to get your heart pumping and keep your immune system healthy.
Water gifts you with many benefits, including improved cognitive function. When you’re dehydrated, you may experience fogginess, mood changes, and even constipation. Hydrate sufficiently every day to keep your body, including your immune system, in perfect working order.
Poor Sleep Schedule
If your sleep schedule is erratic, your body doesn’t have any predictable way of knowing when it gets a chance to recharge. This can increase the level of cortisol in your body, which is a stress hormone, and stress has a negative impact on your immune system. It can also affect other hormone levels such as testosterone and estrogen. Pick your sleep schedule and stick to it every night.
Benefits of Immune Boosters
Immune boosters, depending on their ingredients, are loaded with many benefits for your overall health, such as:
- Anti-viral properties to help ward off illnesses
- Shortening the duration of bacterial and other infections
- Supporting the body in the fight against any infection
- Can assist with pain reduction due to anti-inflammatory properties
- Supporting the respiratory system
- Supporting gut health
- Antioxidant support to fight free radicals
Immune boosters are just one component to a healthy lifestyle. When you incorporate an immune booster into a lifestyle that prioritizes your health, including a well-balanced diet and regular exercise regimen, you can bask in all the benefits they offer.
