What is ellagic acid?

Ellagic acid is a naturally occurring polyphenol found in certain fruits and nuts. It is studied mainly for antioxidant and anti-inflammatory activity.

What foods are high in ellagic acid?

Common sources include berries such as raspberries and strawberries, pomegranate, and some nuts. In many foods it occurs as ellagitannins that can release ellagic acid during digestion.

What are the potential benefits of ellagic acid?

Research suggests antioxidant and anti-inflammatory effects, with additional interest in chemopreventive mechanisms in preclinical models. Human evidence is limited and results can vary by dose and formulation.

What is a typical ellagic acid supplement dosage?

Common supplemental ranges are often around 100–500 mg per day, depending on the product. Follow the label and consider discussing dosing with a clinician, especially if you have medical conditions.

Is ellagic acid safe and are there interactions?

Ellagic acid from foods is generally considered safe for most people. With supplements, safety data are more limited, and interactions are possible, so use caution if pregnant, breastfeeding, or taking medications.
