11 Immune-Boosting Ingredients To Add to Your Smoothies

It’s that time of year when the weather is changing, and so many people are being hit by coughs, colds, and flu. Plus, with a pandemic sweeping the globe, there’s no time like the present to shore up your immune system. 

If you’re not feeling 100 percent, it can be tempting to reach for the classic comfort foods, such as chicken noodle soup or a nice big bowl of mac and cheese. However, these foods are often filled with unhealthy, processed ingredients and too much sodium, so they aren’t actually the best way to support your body’s recovery. Often, typical comfort foods can cause inflammation and block our natural defense systems, making us more likely to get sick and causing us to take longer to get over an illness.

Whether you’re trying to dodge a seasonal flu or avoiding that nasty bug that’s going around, having a strong immune system is your best bet. No matter how many times you wash your hands or disinfect grocery cart handles, at some point, your body will become exposed to a bug. 

Hopefully, when this happens, your immune system kicks in to prevent any illness from taking hold. Unfortunately, if your immune system isn’t top-notch, this doesn’t always work, and you get sick.

If you want to prevent illness, the trick is to reach for natural alternatives which can help reboot your immune system and kick nasty ills and chills to the curb. Packing your daily menu with nutrient-rich whole foods and immune-boosting ingredients can be a game-changer, especially during the colder months of the year.

Here are some of our favorite ingredients that you can throw into your morning smoothie to help rev up your immune system!

Top Immune-Boosting Smoothie Ingredients

Greens Powder

Look for an organic greens powder where the ingredients have been freeze-dried to keep the nutrients intact. This is an excellent smoothie additive to boost your immune system and fight the oxidation of cells. 

A high-quality greens powder can:

  • Build immunity against bacteria, viruses, and toxins
  • Provide powerful anti-inflammatory effects
  • Boost cardiovascular and digestive health
  • Support the health of mucous membrane growth which stops pathogens from entering the body
  • Detoxify the liver to help excrete any nasties 

Look for a greens powder with ingredients such as kale, wheatgrass, spirulina, and kelp. Organic is best if you can find it, and watch out for extra sugar or sweeteners.


Kefir is a type of yogurt made with milk (dairy or non-dairy) and culture. It can be made from any source of milk, such as goat, sheep, cow, rice, cashew, or coconut. It can even be made using coconut water.

The kefir culture “grains” contain a beneficial symbiotic mixture of lactic acid bacteria and yeasts, which is loaded with vitamins and minerals, and can help increase bone density, boost immunity, and improve digestion. Although kefir is a dairy food, the fermentation makes it safe for many lactose-intolerant people.

Kefir can assist with:

  • Providing many nutrients, including calcium and vitamin B12
  • Supporting the body with a wide variety of bioactive compounds, including organic acids and peptides that contribute to its health benefits
  • Boosting the immune system with up to 61 different strains of probiotics


Collagen is a protein found abundantly in the body, present in connective tissues, such as the skin, tendons, ligaments, gut, blood vessels, bones, intervertebral discs, and muscle tissue. It’s one of the most common proteins; however, as we age, the natural production of collagen decreases, making it very important to include it as a supplement in our daily routine.

Adding collagen to your smoothies can help:

  • Keep skin looking great and prevent aging
  • Support the gut by reducing inflammation and repairing the digestive tract 
  • Improve the function of the immune system, of which 70 percent is located in the gut


Due to its strong anti-inflammatory and antioxidant effects, ginger may boost immune health. Upping your intake of antioxidant-rich foods like ginger can combat inflammation and keep your immune system healthy.

Ginger is packed with natural actives called gingerols, paradols, sesquiterpenes, shogaols, and zingerone, all of which have powerful anti-inflammatory and antioxidant properties.

The powerful compounds in ginger are:

  • Anti-inflammatory, working to heal the body and reduce pain
  • Great for digestion, helping with nausea and motion sickness 
  • Rich in antioxidants, fighting harmful compounds in the body
  • Very good for boosting the immune system

Dark Colored Berries

Berries are rich in vitamin C and bioflavonoids, phytochemicals found in fruits and vegetables that may work as antioxidants and prevent injury to cells.

One cup of strawberries contains as much as 100 mg of Vitamin C, and dark berries such as blueberries are especially high in bioflavonoids. For an optimal immune system boosting effect, eat a bowl of mixed berries, or vary which berries you choose from day to day, rather than eating just one type. 

Some of the best berries for boosting the immune system include:

  • Boysenberries
  • Blueberries
  • Black currants
  • Elderberries 
  • Mulberries
  • Huckleberries
  • Blackberries 


Lemons are high in vitamin C, which provides strong support for the immune system. Vitamin C improves the function of what are called natural killer cells, which help to eliminate infection and aid in antimicrobial activity. It also supports the body’s own helper cells, such as lymphocytes, while supporting the body’s cells to maintain their integrity and resist oxidative damage.

Eating or juicing lemons – which also contain a good amount of immune-boosting zinc – helps to boost your immune system and keep you healthy, especially when you are battling a cold or other infection.

Vitamin C and zinc found in lemons has been shown to:

  • Improve the severity of symptoms
  • Shorten the time of illness with common illnesses
  • Help with respiratory infections, viruses, and the common cold


Parsley is packed with essential oils and antioxidants, to the point that it’s often called a superfood. It benefits the body in many ways and is considered a naturally effective treatment for a wide range of symptoms and diseases. This herb has long been considered an all-natural free radical scavenger, heart protector, brain protector, antidiabetic, antibacterial, and digestive aid.

Some of the benefits of parsley include:

  • High in antioxidants such as luteolin, apigenin, lycopene, beta-carotene, and alpha-carotene which fight oxidative stress, inflammation, and aging
  • Contains essential oils which are chemoprotective (protect from cancer)
  • Improves digestion and relieves bloating
  • Has antibacterial and antifungal properties

Raw honey

The phytonutrients in raw honey have antibacterial and antiviral properties that can help to boost your immune system and fight sickness. It can also help with everything from low energy to sleep problems and seasonal allergies. 

Here’s how to choose the right honey for the best health benefits:

  • Choose local honey when possible (try the farmer’s market)
  • Organic honey is best if it’s in the budget
  • Make sure your honey is raw and unpasteurized


Acai berries come from South America and look a bit like grapes or blueberries. The dark fruit is reported to support the human immune system through the immune-enhancing effects of natural compounds called polyphenols.

Some of the benefits of acai include:

  • Lower blood cholesterol levels
  • Stop cancer cells from forming and spreading
  • Boost brain function
  • Support immunity to fight every day ills and chills 


Turmeric contains medicinal substances called curcuminoids, the most important of which is curcumin. Curcumin is the ultimate health-promoting compound.

If you can get your hands on fresh turmeric root, it adds a delicious earthy flavor. Otherwise, use dried, preferably organic turmeric powder.

The compounds in turmeric have been shown to have the following properties:

  • Antioxidant
  • Anti-inflammatory
  • Antiviral
  • Antibacterial
  • Antifungal
  • Anticancer


Medium-chain triglycerides, or MCTs, are a healthy fat which has become popular in the health food and nutrition space lately. This type of fat can reduce inflammation by killing off bad bacteria, such as candida or yeast, that can overgrow in our intestines. MCT oil is also known for increasing energy and mental clarity while helping with appetite control and weight loss.

Some of the key facts about MCT oil include:

  • MCT oil most often comes from coconuts
  • It’s a clear, tasteless oil 
  • Popular for intermittent fasting and the ketogenic diet
  • Easy to add to smoothies for a nutritional boost
