Royal jelly is a fantastic source of enzymatic substances that act as biocatalyts, promoting and stimulating the metabolism at cellular level. The composition of royal jelly, unlike other hive products, varies little and the product is not so closely linked to the harvest area. It is composed of a water base (approximately 66%) along with lipids, carbohydrates and proteins. In the hive, the queen is nourished exclusively with this substance and the fact that she is the only bee who can live for up to 5 years, while the life span of a worker bee rarely extends beyond a few weeks, has fuelled man’s curiosity and interest in this substance. Royal jelly is used as a food supplement and, since it is extremely nourishing, it is traditionally given as a dietary boost to people of all ages, especially during changes of season.
