What is cichoric acid?

Cichoric acid is a naturally occurring polyphenolic compound found mainly in Echinacea and some other plants. It is studied for antioxidant and immune-related effects.

What are the potential benefits of cichoric acid?

Preclinical research suggests antioxidant and anti-inflammatory activity and possible immune-modulating effects. Human evidence is limited, so benefits in people are not well established.

What is a typical dosage range for cichoric acid?

Supplement amounts vary by product, but a commonly referenced range is about 5–100 mg per day. The effective dose in humans is not clearly defined.

Is cichoric acid safe?

Safety data in humans are limited, and tolerance may depend on the source extract (such as Echinacea). People who are pregnant, breastfeeding, have allergies to Asteraceae plants, or use immune-affecting medicines should consult a clinician before use.

Cichoric acid

Limited research available·3/10

A higher score indicates better study conditions, but not necessarily effectiveness.

Cichoric acid is a polyphenolic compound found mainly in Echinacea, studied for antioxidant, anti-inflammatory, and immune-modulating properties, but with limited human evidence.

Anti-inflammatory Antioxidant Immune Booster

dose range

5–100 mg

Once or twice daily, based on typical Echinacea extract usage.

Consumption

Take orally as part of a supplement derived from Echinacea; best with water, with or without food.

Not fat-soluble.

Best time

Any time of day; if using as part of an immune regimen, consistent timing is recommended.

Description

Cichoric acid is a natural phytochemical abundant in Echinacea and certain other plants. It is reputed for its antioxidant, anti-inflammatory, and potential immune-boosting effects, though most research is from laboratory or animal models.
