I use the dac oil in the past and really liked it. I've also used several other dac products and have been happy. I do know that the bloom is on sale right now for another week. I'm friends with the local dac dealer. I've never used the bloom before but have heard good things.
There are several nice ingredients in DAC Oil, but the first two are Corn Oil and Soybean Oil. I am not a fan of either as they are solvent extracted. In general I am not a fan of added refined oil top dressed on feed. The Flax oil and fish oil can be a real benefit and are generally fed in small amounts. This is a deal where a little will brighten up a horses hair coat, and my help some with hoof condition. But, there is a point, in my opinion, where it may become disruptive to the horses ability to absorb water soluble vitamins. If you love it feed it, just do not overdo it.
