It is produced by young nurse bees between the ages of 5 and 12 days and fed to the queen, the queen, which ensures the survival of the species. The queen is genetically identical to the other bees, but because she feeds only on royal jelly, she is almost twice the size of the worker bees, survives as many as 15 broods, and is the only sexually developed one in the hive. It is considered the most fertile creature on the planet because it lays up to 3,000 eggs per day, the total mass of which exceeds its own. In ancient Egypt, royal jelly was used even by the pharaohs, who called it "food of the gods", and today we know that its exceptionality is based on the content of the unique unsaturated fatty acid 10 HDA (10-hydroxy-2-decenoic acid), which it is not found anywhere else in nature, it cannot be found anywhere else. The content of 10 HDA is an important measure of the quality of breast milk, therefore at Medex we standardized its value in the products and thus ensured their constant quality.
