Fluoride and Kombucha

Updated: Aug 8, 2019

A few weeks ago a friend and I were talking about how I had made the switch from morning coffee to morning kombucha. If you have never heard of kombucha, head on over to

and Sara will not only tell you what it is, but show you how to make it.

During this conversation, I told Leah that I felt so much better, and loved that it was good for my gut.

She proceeded to rain on my parade and inform me that kombucha had been found to have high levels of fluoride. Insert eye roll here. 

If you don’t know why that’s a problem, I will touch on it briefly, but you really should head over to 

and check out her blog on it.

I’m not gonna lie, I was pretty upset about this for a while. The feeling that we literally can’t escape these horrible toxins overtook me a bit. Coffee is usually heavily chemically processed. While I do enjoy my coffee, I’m trying to switch to better alternatives. Plus, I usually have a bad blood sugar crash the days I drink it- not good. But what am I to do if kombucha is bad too?

Then, after a while mulling it over, I started wondering if there is a difference between naturally occurring fluoride and chemical fluoride. After all, ascorbic acid is not the same as sodium ascorbate. Too much vitamin A will kill you but carrots won’t. Folic acid is toxic for many but folate isn’t. Surely, fluoride could be the same, right? 

I decided to find out. Hours of research and digging commenced.  And it turns out, I wasn’t wrong. 

As always, all links will be at the bottom.


What is Fluoride?


First off, let’s discuss exactly what fluoride is. Fluoride is any compound that contains a fluorine ion. When by itself, it is extremely toxic to humans. But it is typically paired with another element, and that element can either increase or decrease absorption. The two types of fluoride in question are sodium fluoride and calcium fluoride. Calcium acts as an agent to detox the body and prevent too much absorption. Sodium makes the body absorb it more readily.  Fluoride in drinking water and toothpaste, sodium fluoride, is a toxic manmade fluoride element riddled with aluminum, steel, cement, phosphate, and more. And paired with sodium, all of that absorbs easily into your system.  On the contrary, calcium fluoride isn’t actually fluoride- at least not in the sense that we would typically think. Calcium fluoride is a mineral- a trace mineral to be exact. It is needed in small quantities to strengthen bones and teeth, and the calcium prevents the body from absorbing too much. Calcium actually helps to detox the body from fluoride toxicity.  So, there is a vast difference between the two. One is a lethal neurotoxin and one is a trace mineral. One benefits your body and one cause severe damage. Sodium fluoride was originally added to things to mimic the results of calcium fluoride. But manmade can never truly mimic naturally occurring.  While it is completely plausible that some of the added fluoride from drinking water has leeched into the soil, the vast majority of the fluoride found in soil and plants is naturally occurring, and thus doesn’t carry the same toxic risk as synthetic. So enjoy your Kombucha and the benefits to your gut, and don’t even think twice if someone tells you it contains fluoride. Your body actually needs the kind it has.




Calcium fluoride isn’t easily absorbed into the body but sodium fluoride is. Manmade fluoride is toxic and full of additives. Calcium fluoride is not really fluoride

Calcium fluoride is a mineral

But not a macro mineral, a trace mineral

Calcium helps to detox fluoride from the body, meaning in combination with fluoride, it prevents the body from absorbing too much.
