Grapefruit juice is a tangy beverage made from the fruit of the grapefruit tree, which is a hybrid of the pomelo and orange. It is known for its refreshing taste and vibrant color, ranging from pale yellow to deep pink, depending on the variety of grapefruit used. Rich in vitamins, particularly vitamin C, grapefruit juice is often consumed for its potential health benefits, including boosting the immune system and aiding digestion. However, it can interact with certain medications, so it's important to consult a healthcare professional if you are taking prescription drugs.
