Patient Education

Grapefruit


What is it? Grapefruit (Citrus paradisi) is a citrus fruit. It has been used for weight loss. It has also been used for other conditions, but with limited evidence.

Grapefruit is a source of vitamin C, fiber, potassium, pectin, and other nutrients. People use the fruit, oil from the peel, and extracts as medicine. Drug interactions with grapefruit juice are well documented. Before adding it to your diet, check with your healthcare provider if you take medications.

People commonly take grapefruit by mouth for weight loss, asthma, high cholesterol, cancer, and many other conditions, but there is no good scientific evidence to support these uses.
