1 side affect of Royal Jelly is weight balance.....and return of appetite.
Books say Royal Jelly has 5 usable flower based hormones and that along with all the B vitamins and dense nutrients makes Freeze Dried Royal Jelly the best supplement and is not an herb, but produced from flowers.
the Japan Hospital and Dr. Cass Ingram book: Longevity give the best suggested daily dosage for life----I take much more and give allot to my dogs daily.

Old books say royal jelly has been made synthetically since 1950's, I suspect as much as 90% sold commercially is a synthetic product. If in a pill or commercial small bottle--odds are that can be a synthetic.
