The Maximizer Plus Deer Mineral by Real World Wildlife Products was developed over the course of 20 years, involving both captive and wild whitetail deer. It uses a scientifically formulated blend of over 20 micro and macro nutrients in precise ratios to each other. Other deer mineral products on the market are most just salt – while this will attract deer, it offers very little in the way of actual nutrition. The Maximizer Plus Deer Mineral attracts deer too, but provides substantially more benefits. Giving the herd on your property year-round access to Maximizer Plus Deer Mineral allows the bucks to maximize genetic potential of antler growth, increases the overall health of the herd, and allows the does to produce healthy fawns.
