The Dual Nature of Chicory's pH
Determining if chicory is alkaline or acidic is not a simple matter of a single measurement, as the answer depends on the form of the plant and how it affects the body's internal environment. On a surface level, measurements of raw chicory root show a slightly acidic pH, typically around 5.98. However, this reading does not tell the whole story. What many people find beneficial about chicory, particularly when consumed as a coffee substitute, is its effect on the body's metabolic processes and its overall low-acid profile. This is a crucial distinction between the actual pH of a substance and its potential renal acid load (PRAL), or how it influences the body's acid-alkaline balance after digestion.
The Alkaline-Forming Effect
One of the main reasons chicory is often referred to as alkaline is its rich mineral content, particularly potassium. During digestion, these minerals are metabolized in a way that helps to neutralize acids in the body, creating an overall alkaline-forming effect. This metabolic action is what makes chicory a gentle alternative for those who find traditional coffee too harsh or acidic. Manufacturers of chicory-based beverages like Teeccino specifically highlight this feature, noting that the potassium and inulin in their products aid in restoring an alkaline balance.
The Role of Inulin and Gut Health
Beyond its mineral content, chicory root is a powerful source of inulin, a prebiotic fiber that feeds beneficial bacteria in the gut. A healthy gut microbiome is fundamental to overall digestive health. When beneficial bacteria flourish, they create a balanced and diverse gut environment, which can lead to better digestion and enhanced nutrient absorption. For individuals with conditions like acid reflux or gastritis, promoting a healthy gut with prebiotics can be more beneficial than simply consuming low-acid foods. By supporting the growth of good bacteria, inulin helps soothe the digestive system and alleviate common issues like bloating and indigestion.
Chicory vs. Coffee: The Acidity Showdown
For many, the debate over chicory's pH centers on its use as a less acidic coffee alternative. The difference is clear when comparing the two, both in raw pH and metabolic effect.
| Feature | Chicory Coffee | Regular Coffee |
|---|---|---|
| Acidity Level | Low acidity, gentler on the stomach. | Mildly acidic, pH typically 4.85–5.10. |
| Effect on Digestion | Prebiotic fiber (inulin) promotes gut health and can soothe the stomach. | Can irritate the stomach lining and trigger acid reflux in some individuals. |
| Caffeine Content | Caffeine-free (when made from pure chicory root). | High caffeine content, a stimulant that can increase stomach acid production. |
| Taste Profile | Earthy, slightly bitter, and nutty flavor profile. | Classic rich, dark, and robust flavor. |
The Different Forms of Chicory
The final form of chicory impacts its properties. For example, spray-dried instant chicory powder is reported to have a more acidic pH range of 4.0 to 5.0. This is likely due to the processing method and concentration. In contrast, simply roasting and brewing the root produces a low-acid, low-bitter beverage. Chicory leaves, which are used in salads, also contain different compounds than the root, including vitamins and antioxidants. The key takeaway is to be mindful of the chicory product you choose, as not all forms are created equal regarding acidity and their digestive impact.
What are the main forms of chicory?
- Roasted Root: This is the most common form for brewing coffee-like beverages. The roasting process mellows the flavor and contributes to its low-acid profile.
- Instant Powder: Made from highly processed, spray-dried root extract, this form can have a higher acidity level.
- Fresh Leaves: Used as a leafy green in salads, chicory leaves contain various nutrients but are not typically used for their pH benefits in the same way as the root.
Who Benefits from Chicory?
Chicory is an excellent choice for several groups of people:
- Individuals with Acid Reflux: The lower acidity of chicory coffee makes it a far gentler alternative to traditional coffee, which is known to aggravate acid reflux and heartburn.
- Those with Sensitive Stomachs: The combination of low acid and prebiotic content makes chicory an ideal beverage for people who experience digestive upset from traditional coffee.
- Health-Conscious Individuals: Chicory offers numerous health benefits beyond its low acidity, including liver support and antioxidant properties, making it a great addition to a healthy diet.

Conclusion: The Final Verdict on Chicory's pH
While chicory's raw state is slightly acidic, its metabolic effect is alkaline-forming, primarily due to its high potassium content. The roasted root, used as a coffee substitute, is significantly less acidic than regular coffee, making it a soothing option for sensitive stomachs. Furthermore, the prebiotic fiber inulin found in chicory promotes a healthy gut, which can reduce digestive distress. Therefore, for most practical purposes, especially for coffee drinkers, chicory is considered an alkaline-friendly food and a beneficial alternative for digestive health.
