Conditioner and Supplement

I'm looking to buy a new supplement and conditioner. I have done some basic research (google) and a couple of products caught my attentionl; showbloom! And Calf Manna. Has anyone used either of these products and can give me some good feedback on pros and cons. It would be greatly appreciated.

Showbloom is a fat supplement

Calf manna is a corn based all stock supplement

What are you trying to do??

What is the horses total diet now???

You would be better off going with a ration balancer in place of your current feed at 1lb a day and then adding somethign like showbloom of Max E Glo
