Immune Booster Smoothie

October 26, 2014

One simple, delicious smoothie with a powerful immune boosting punch from elderberries, vitamin C, and gut building probiotics! Very kid friendly in taste too!

Please know I would never personally recommend any product I wouldn’t use on my own family. Please also note that I am not a doctor, nor claim to be one. The recommendations in this post are based on my own research and what has worked really well for keeping my family’s immune system boosted.

I am pretty sure every library storytime and preschool drop off we have been to this fall there are one or two kids there with croupy coughs and drippy noses. And in the 2 months since kindergarten started, I have already had reports from my “little momma” that so-and-so was out sick today, emails sent home about pink eye, and on and on.

Since I don’t have a newborn this year, I’m still getting the girls out and about, and I’m really not sweating it. I know my kids’ bodies are ready to fight infection, and I don’t want them kept in a bubble.

We will, and certainly have, come in contact with cold bugs, and probably even the flu. My goal in the fall and most of the winter is getting immune supporting bone broth in the girls daily. Whether in soups or mugs, bone broth is my weapon of choice to battle bugs.

Sometimes, however, I feel we just need a big boost in addition to that. If it has been a long week and I know the girls are tired or run down. If I know there is a cold or flu bug going through the classroom that my daughter spends 7 hours a day in. Or that kid from library time that just loves babies gives her a runny nosed hug.

Immune Booster Smoothie
This immune booster smoothie is great for breakfast or lunch. Full of friendly fats from coconut oil and whole raw milk, and filling protein and gut supporting grassfed collagen. You could also freeze it into popsicles!


  • VITAMIN C: Vitamin C supports the immune system, and when you source it right, it really can enhance your body’s ability to fight infection fast. Please note just simple ascorbic acid is not what we are talking about here. UPDATE 2021 :: I love the new Acerola Cherry Vitamin C from Perfect Supplements for smoothies! There is a very mild fruity flavor so it blends in well with this smoothie, and is a whole food source of quality Vitamin C!
  • PROBIOTICS: Since your immune system resides mostly in the gut, having your good bacteria up to par is very important. There needs to be balance in the bacteria population so I like to rotate our probiotics to introduce new gut flora. I like to start with THIS one, and then rotate with THIS. UPDATE 2022 :: I still recommend the powdered probiotics linked in the previous statement – those are great to add into a smoothie. THIS is also a great one for kids to add in, or THIS one is good too. My kids will swallow this capsule which I very highly recommend, but it will not blend into a smoothie well as it has an odor and is soil based which is why I love it so much.
  • ELDERBERRY SYRUP: Specifically beneficial in helping support the body during viruses, elderberry syrup is great for colds and flu. It also has a very pleasant taste so it helps sweeten the smoothie.

Immune Booster Smoothie

Skip any vitamins the kids might turn their noses up at and make this immune-boosting smoothie.
Prep Time5 minutes
Total Time5 minutes
Course: Drinks
Cuisine: American
Keyword: how to make an immune boosting smoothie, immune boosting smoothie, immune boosting smoothie recipe
Servings: 1 servings
Author: Renee -


  • ¾ cup frozen organic blueberries could use any frozen berries
  • 1 cup whole raw milk, yogurt, or coconut milk (water works too in a pinch)
  • 1-2 TB organic coconut oil melted (depending on your taste)
  • Juice of ½ lemon
  • 2 TB cold soluble grassfed collegen See Tips section for more info on this
  • 1 TB homemade elderberry syrup if using store bought, follow the serving directions for 1 dose
  • Vitamin C & probiotics per supplement dosing directions


  • Everything into your blender and blend until smooth.


  • This makes 1 “adult” sized smoothie – my 3 and 5 year olds split one. I have been making a little extra for my 1 year old to have and she has been really liking them.
  • I really love having the cold soluable grassfed collagen around for smoothies. Not only does it give a protein source to smoothies very easily (just dump it in!), it is also very helpful in restoring gut lining to normal.
  • Add or subtract the supplements as you feel necessary. You can read more about the vitamin C I like to use for immune boosting HERE.
  • If your kiddo is already feeling ill, you can make the smoothie on the blander side if they are recovering but can still get a small amount of food in. Leave out the milk and use water. Maybe back off on the coconut oil. Maybe add a pinch of sea salt to add some minerals for electrolyte balance.
  • I just use my simple Magic Bullet to blend this all up! This serving fits perfectly!

    I’ve actually never added collagen to my smoothies. Added protein sounds like a good idea! There seems to be a lot of sickness going around the town right now (flue & respiratory stuff, mostly) so this is timely!

    I am curious about the multivitamin your kids take. You said it contained Vitamin C, which is not the same as citric acid, correct? I read in the reviews that they changed the formula, removing a number of controversial ingredients, but seemingly adding a lot more, including cane sugar and citric acid. They also said the new formula doesn’t taste good. I noticed you posted this after the formula change, and was wondering your thoughts on those things? I am looking for a kids’ multi that specifically does NOT contain folic acid, but true folate instead.

    • Reply Renee Kohley September 26, 2015 at 12:37 pm

      Hi Ashley! That’s a great question! Yes since the publish date of this post there are some things that have changed in the formula of the multi. Also, since the publish date of this post I am approaching supplements a little differently with my kids now that I am working with an NTP for my supplement needs. I do still give these multivitamins to my kids especially during the school year, however I give them a separate whole food vitamin C (the C in the GOL multi is still a whole food source by the way – not ascorbic acid so it is good just not enough for immune boosting – the citric acid you are referring to is in the coating to make it shelf stable – not for vitamin C sourcing – their C sourcing is whole food.), the folic acid in this multi is in the form of folate which is important to me too – believe me I have checked 🙂 I have MTHFR mutations so I know it is possible my girls do to so folate is importa to me as well. my supplement needs. I am not concerned about the sugar – it is in the form of sucanant first of all not just processed cane sugar – sucanat is raw unprocessed sugar. And to be honest I would rather my kids be ingesting a food like sucanat than xylitol. It is also just so minute and my kids don’t have sugar anyway other than that so I’m just not concerned. It is a good product ingredient-wise for a multi so, yes I am still ok with it. I am however approaching the multi thing differently once my kids can can swallow pills (which right now is only my 6 year old) I am switching to using grassfed beef liver pills instead of multis per my NTP’s suggestion. They contain more vitamins and minerals that our bodies need in a real food way. She also drinks nettles tea infusions most days of the week that provide numerous minerals as well. This is how my NTP has me doing things so I’m just doing it that way once the girls can swallow – my 4 year old can swallow a small probiotic pill but the liver pills are a little bigger. I hope this helps a little 🙂
