Fresh grapefruit juice
Fresh grapefruit juice is rich in vitamin C, potassium, and bioactive flavonoids. It has nutritional benefits but is known for interactions with many medications due to furanocoumarins inhibiting cytochrome P450 enzymes. Generally safe to consume but caution advised if taking certain drugs.
