More accurate to call them Pollen supplements.
Candipoline is a very low protein fondant with about 2% pollen. This is going to have minimum impact on brood rearing or longevity of workers..
Of those available I'd say Ultrabee is the best of a not very good bunch. Unfortunately it's claim of having a fully balanced amino acid profile suitable for honeybees is false. You will notice in the declaration that Tryptophan is absent, this AA is important as it need to be at the correct level and balanced In the correct ratio to other AA's.
If Tryptophan is out of sync it limits protein availability to the honeybee.
