With Coronavirus cases on the rise worldwide, many are fearful of getting sick and looking for ways to boost immunity.  You might be wondering if you can avoid or treat the flu and still stay keto, and the answer is yes!

Every family has their go-to remedies when sickness hits, and one of ours has always been Elderberry (Sambucus Nigra) Syrup, which as been proven to reduce the symptoms and duration of cold and flu viruses. 

In fact this study from a few years ago has shown that compounds found in elderberries worked against H1N1 in a similar way as medicines such as Tamiflu!  Pretty impressive results for a tiny berry if you ask me!


This low carb elderberry syrup boosts your immune system and is proven to reduce the duration of cold and flu viruses!


One of my issues with the store-bought elderberry syrups is that they contain plenty of sugar and carbs, so a few tablespoons a day can put your ketogenic state at risk.  There are some sugar free elderberry syrup options but they all seem to contain stevia, which I’m allergic to.

The other problem with store-bought elderberry syrup is cost – a small bottle can get pretty pricey at almost $20 for around 8oz.  Ouch.

For those reasons, I decided to make my own keto elderberry syrup – giving me all of the same immunity boosting health benefits at a fraction of the cost.

I ordered a whole pound of these dried organic elderberries for around $20 on Amazon.  I can make about half a gallon of this keto elderberry syrup with that amount of berries – all for around the cost of one 8 ounce bottle of store-bought!



Did I mention it’s super easy?  I simmer the ingredients, blend them, strain them, and into the fridge it goes for whenever I need it.  

I added some sliced ginger, cinnamon sticks, and orange zest strips to my syrup while it simmered, which gave it a lovely flavor.  It’s pleasant on its own if you just down a spoonful, but it’s also tasty enough to put on yogurt or even your cream cheese pancakes!

In addition to this keto elderberry syrup, when we’re experiencing cold or flu-like symptoms, we load up on Vitamin C, Zinc, and Oregano Oil, which gets us feeling better in no time. 


Cup of tea with keto elderberry syrup added


To soothe a sore throat, I like to enjoy this keto elderberry syrup in a cup of hot tea with some extra ginger and orange peel.  You can also freeze the syrup into ice cubes and then add it to water and sip it cold. 

However you choose to ingest it, this keto elderberry syrup is a valuable addition to your immunity boosting arsenal!

It should be noted that I am not a medical professional, nor can I predict how your body will react to this keto elderberry syrup. I recommend taking a small amount first to determine if you have an allergy to the berries. Then if there is no reaction after a couple of hours, you should be safe to continue using it. Also, don’t simply take my word for it on the health benefits of Elderberries – do your own research via a Google search and see for yourself!
