>A) Is Brood Boost (Mega bee) considered an organic food suppliment?
There are no organic standards, but if you want to keep them healthy even the people who worship scientific studies know that pollen is better for the bees than substitute. Bees reared on substitute don't live as long and are not as healthy.
>B) What are considered "natural suppliments" or " natural health remedies" ?
If they need pollen, the hard line would be real pollen. Since that's quite expensive and I often run short I sometimes mix it half and half with substitute. But I try never to get below 50% pollen.
As far as remedies, the best remedy is to keep the hives strong and healthy. The best way to do that, IMO, is natural food as much as possible (honey and pollen) and natural sized or small sized cells.

They were probably treated before they were shipped. If you like you can dust them with powdered sugar.
