I used the mineral supplements from whitetail institute .30-06 and optimize i believe.the bears loved it
.I have also used the deer caine.goes fast buts its mostly salt.go to an animal feed store if ya got one they had these apple flavored blocks for deer cant remember the name the deer would feed at em everyday during the summer.porcupines loved em too again so did the bears.I kept it close to the cabin200yrds so we could see critters from insided
