Royal jelly is a milky secretion produced by worker honey bees. It typically contains about 60% to 70% water, 12% to 15% proteins, 10% to 16% sugar, 3% to 6% fats, and 2% to 3% vitamins, salts, and amino acids. Its composition varies depending on geography and climate. This product gets its name from the fact that bees use it for the development and nurturing of queen bees.
