This feeding supplement contains 20 amino acids that are vital for honeybee health. It can be used alone with sugar syrup, or in combination with Honey B Healthy when feeding sugar syrup to your bees in spring. The main purpose of it is to give a colony's brood the nutrition that they would normally get from fresh pollen. Also, the pollen that has been stored in the hive all winter is rejuvenated if and when the bees store this feed in the cells where it is stored.
