4 oz ROYAL JELLY POWDER 100% PURE NATURAL LYOPHILIZED POTENCY 10-HDA 6% Royal Jelly is a secretion that comes from the heads of worker honey bees. Used in the formation of new queen bees, royal jelly is actually fed to all bees in the larvae stage for about 3 days, after which it is only fed to the larva that has been chosen to become the next queen bee. Just like it works wonders for the health of queen bees, it can benefit humans in some amazing ways too. Here are some of the reasons Royal Jelly, and 10-HDA in particular, is so good for humans: Supports cognitive function Great brain food Promotes longevity Great for the skin Promotes collagen production Hormonal support Supports overall health and wellbeing Effective anti-aging ingredient in topical skincare formulations Suggested dose is 150mg two to three times per day.
