How does Grapefruit work?

Grapefruit is a source of vitamin C, fiber, potassium, pectin, and other nutrients. Some components might have antioxidant effects that might help protect cells from damage or reduce cholesterol.

It is not clear how the oil might work for medicinal uses.

Are there safety concerns?

Grapefruit is LIKELY SAFE in the amounts normally used as food and POSSIBLY SAFE when taken by mouth for medicinal purposes.

Grapefruit is POSSIBLY UNSAFE when taken by mouth in high amounts. If you take any medications, check with your healthcare provider before adding grapefruit to your diet or using it as a medicine. Grapefruit interacts with a long list of medications (see "Are there any interactions with medications?" below).

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of grapefruit during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Breast cancer: There is concern about the safety of drinking excessive amounts of grapefruit juice. Some research suggests that postmenopausal women who consume a quart or more of grapefruit juice every day have a 25% to 30% increased chance of developing breast cancer. Grapefruit juice decreases how estrogen is broken down in the body and might increase estrogen levels in the body. More research is needed to confirm these findings. Until more is known, avoid drinking excessive amounts of grapefruit juice, especially if you have breast cancer or are at higher than usual risk for developing breast cancer.

Hormone sensitive cancers and conditions: Consuming large amounts of grapefruit might increase hormone levels and therefore increase the risk of hormone sensitive conditions. Women with hormone sensitive conditions should avoid grapefruit.
