Overview Information

Ellagic acid is a naturally occurring substance. The best sources of ellagic acid in the diet are strawberries, raspberries, blackberries, cherries, and walnuts.

Ellagic acid is used for cancer, dark skin patches on the face (melasma), memory and thinking skills (cognitive function), and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Ellagic acid may bind to chemicals that cause cancer. It may also prevent the growth of cancer cells and improve the safety and efficacy of some cancer drugs. However, ellagic acid is poorly absorbed and is also eliminated quickly from the body. These characteristics may limit its usefulness as a medicine.


Uses & Effectiveness?

Insufficient Evidence for

  • Memory and thinking skills (cognitive function). Early research shows that taking ellagic acid for 12 weeks improves mental function and IQ in overweight males. But it doesn't improve these outcomes in males with normal body weight.
  • A sexually transmitted infection that can lead to genital warts or cancer (human papillomavirus or HPV). High-risk HPV is linked with cervical cancer. Early research shows that taking ellagic acid and graviola for 6 months has antiviral activity against high-risk HPV. It might also prevent precancerous cells from becoming worse in women with high-risk HPV and precancerous cells.
  • Dark skin patches on the face (melasma). Early research shows that applying ellagic acid to the face can lighten brown spots. It seems to work about as well as a prescription skin whitening agent.
  • Prostate cancer. Early research shows that taking ellagic acid during chemotherapy for prostate cancer reduces the side effects of cancer treatment. But it doesn't seem to reduce tumors or improve survival.
  • Cancer.
  • Other conditions.
More evidence is needed to rate the effectiveness of ellagic acid for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Ellagic acid is POSSIBLY SAFE when taken appropriately for up to 3 months. There isn't enough reliable information to know if ellagic acid is safe or what the side effects might be when used long-term.

When applied to the skin: Ellagic acid is POSSIBLY SAFE when used for up to 6 months. There isn't enough reliable information to know if ellagic acid is safe or what the side effects might be when used long-term.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if ellagic acid is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.



We currently have no information for ELLAGIC ACID Interactions.



The appropriate dose of ellagic acid depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for ellagic acid. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
