Is grapefruit juice good for you?

Grapefruit juice is a healthy source of vitamins and minerals. It provides vitamins A and C and is a good source of potassium. The sugar content varies, but unsweetened grapefruit juice has around 22 grams of sugar per 8-ounce serving.

Grapefruit juice can be unhealthy for people taking certain medications, such as lovastatin. A compound found in grapefruit called naringenin can interfere with the body's metabolism of these drugs. This can lead to toxic levels of the medication building up in the body. The effects of grapefruit juice can last more than 24 hours, so it should not be consumed while taking any medication known to interact badly with grapefruit juice.
