Royal jelly is a secretion produced by worker bees that serves as the primary food source for bee larvae and adult queen bees. It is a milky, nutrient-rich substance composed of water, proteins, sugars, lipids, vitamins, and minerals. Royal jelly is believed to contribute to the queen bee's longevity and reproductive capabilities. Royal jelly has been used in traditional medicine for its potential health benefits, which include antioxidant, anti-inflammatory, and antimicrobial properties. It is often bottled and sold as a dietary supplement, skincare product, or ingredient in various food items.
