Ellagic acid is a natural polyphenol found abundantly in pomegranates, raspberries, strawberries, and walnuts. When you eat these foods, your gut bacteria convert ellagic acid and its precursors (called ellagitannins) into active compounds called urolithins, which may be responsible for many of the health benefits attributed to this compound. It has been studied across traditional medicine systems worldwide and is now gaining attention in modern nutritional science.

Ellagic acid works primarily as an antioxidant, neutralizing damaging free radicals before they can harm your cells. It also dials down inflammatory signaling pathways in the body, which may help with a wide range of chronic conditions. Its gut-derived metabolites, particularly urolithin A, have attracted research interest for their ability to support cellular cleanup and muscle health.

Most commonly found as pomegranate extract standardized to a percentage of ellagic acid, or as standalone ellagic acid capsules. Whole food sources like pomegranate juice are also popular. Urolithin A supplements have emerged as a direct way to bypass the gut conversion step entirely.

• Skin aging and UV damage
• Chronic inflammation
• High blood pressure
• Blood sugar and metabolic issues
• Gut health
• Oxidative stress and cellular damage
• Muscle recovery and aging
• Liver health
• Weight management support
• Prostate health (men)

• UV-induced skin cell damage (photoprotection)
• Oxidative DNA damage from free radicals
• Progression of elevated PSA in prostate health monitoring

• Pomegranate — One of the highest known sources of ellagitannins; both the seeds and juice are rich in ellagic acid precursors that convert to active compounds in the body.
• Raspberries — Contain significant amounts of ellagic acid directly, along with ellagitannins, making them one of the best berry sources.
• Strawberries — A good everyday source of ellagic acid; their wide availability makes them a practical way to get consistent daily intake.
• Walnuts — Contain ellagitannins in their skin; also provide healthy fats that may help with absorption of fat-soluble polyphenols.
• Blackberries — Rich in both ellagic acid and anthocyanins, offering a strong antioxidant combination for overall cellular protection.

• Mild nausea or stomach upset at high doses
• Loose stools or diarrhea with excessive intake
• Potential drug interactions via liver enzyme pathways (see interactions)
• Allergic reactions in people sensitive to pomegranate or berries (rare)

• Recommended daily: 200–400 mg of ellagic acid (often delivered via 500–1,000 mg pomegranate extract standardized to 40% ellagic acid). Urolithin A supplements typically dosed at 500–1,000 mg/day.
• Best time of day: No strong preference; morning or midday with a meal is a practical routine.
• With or without food: Best taken with food — particularly a small amount of healthy fat — to support absorption of this fat-soluble polyphenol.
• Time to effect: Antioxidant and anti-inflammatory effects may begin within days; meaningful changes in skin, blood pressure, or metabolic markers typically require 4–8 weeks of consistent use.
• How long to take it: Can be taken long-term as part of a daily wellness routine. Regular cycling is not required, though taking breaks every few months is a reasonable personal preference. Evaluate results after 8–12 weeks.
