At some point, the gut health conversation split into two camps and nobody adequately explained the difference between them. Prebiotics and probiotics appear on the same shelves, in the same conversations, and occasionally in the same products. They are not the same thing.

Here is the clearest way to explain it:

Probiotics are live bacteria. When you eat yogurt, kefir, kimchi, sauerkraut or kombucha, you are consuming microorganisms that, if they survive the journey through your digestive system, join the community of bacteria already living in your gut. You are adding guests to the party.

Prebiotics are the food those bacteria eat. They are dietary fibers — specific types that your body cannot digest — that travel to your colon and get fermented by the microbiota already living there. You are not adding guests. You are feeding the ones already present.

Both matter. They work differently.

Why most people are more deficient in prebiotics

The probiotic conversation is well established. Yogurt commercials have been making the case for live cultures since the 1980s. Kombucha is now in every supermarket. The message has landed: live bacteria are good for your gut.

The prebiotic conversation is less developed, which is odd, because the deficiency is more common. The recommended daily fiber intake is 25-30 grams. The average person gets about half that. The gap is not the result of bad intentions — it's the result of a food system that made it easier to eat refined things than fibrous ones.

You can eat yogurt every day and still be significantly under your daily prebiotic fiber target. The bacteria in the yogurt arrive, look around, and find very little to eat.

Where Cascara Cabinet fits

Cascara Cabinet is a prebiotic drink. It contains 4.2g of prebiotic fiber per can — from agave inulin and Benicaros®, a carrot-derived RG-I fiber with clinical studies showing measurable effects on gut microbiome composition at just 300mg per day. We use considerably more than that.

It is not fermented. It contains no live bacteria. It is shelf-stable and does not require refrigeration. It is not kombucha, and it is not trying to be.

What it does is feed the bacteria already living in your gut — including the ones you may have been carefully cultivating with your morning yogurt. Think of it as the logical complement to a probiotic habit, not a replacement for one.

The science, briefly

The gut microbiome is a community of trillions of microorganisms living in your digestive tract. Research over the last two decades has established that this community affects far more than digestion — immune function, mood, energy metabolism, and nutrient absorption all have documented connections to gut microbiome composition.

Prebiotics specifically have been shown to increase the abundance of beneficial bacteria like Bifidobacterium and Lactobacillus, support immune function, and improve gut resilience. Benicaros® — one of the two prebiotic fibers in Cascara Cabinet — has clinical studies showing these effects at 300mg per day. One can contains 4.2g.

We mention this not to make a health claim but because we know you're going to look it up anyway, and we'd rather you find the actual study than a forum post.

A note on EU regulation

In the European Union, the words "prebiotic" and "probiotic" cannot legally appear as health claims on food and drink labels. This is because the European Food Safety Authority has not approved them as authorized health claims — the evidence base, while growing, does not yet meet the regulatory threshold for labeling purposes.

This does not mean the science is weak. It means the regulatory process moves slowly. We use the words on our website, in our content, and in conversations like this one — because here, we are explaining what the ingredients are, not making a legal claim on a label.

The cabinet is open.
