Grapefruit

Grapefruit is a citrus fruit known for its tangy, slightly bitter flavor and rich nutritional content. It is widely used in whole food applications (eaten fresh, juiced, or processed), and in extracts such as grapefruit seed extract (GSE) or essential oil for antimicrobial, antioxidant, and flavoring purposes. It is also used in functional foods and dietary supplements, especially grapefruit seed extract, which is claimed to support immune health and digestion.
