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 safe in the amounts normally used as food and seems to be safe when used appropriately for medicinal purposes.

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 verify these findings. Until more is known, avoid consuming excessive amounts of grapefruit juice.

Do not use medicinal amounts of grapefruit products if:
  • You are pregnant or breast-feeding.
  • You have breast cancer or at risk of developing breast cancer.
