Royal Jelly is a natural source of many nutrients. Royal Jelly is the only food for the Queen Bee and it enables her to outlive worker bees thirty fold! The Queen Bee is also very fertile, laying up to 2,000 eggs each day throughout her life. This Royal Jelly has been freeze-dried to maintain maximum stability and is among the finest products available. 10-HDA (10-hydroxy-trans-2-decenoic acid) is one of the active, measurable components of Royal Jelly.
