Beta-Glucanase - Clinically proven to activate the immune system by stimulating production and activation of macrophages, the natural pathogen scavenger in the course.

Coconut Oil - Contains valuable lauric acid (which has antibacterial, antiviral, and anti-fungal properties), fiber, vitamins, and minerals.

Stabilized Rice Bran - A good source of fat. Research has confirmed that the fat in stabilized rice bran is highly digestible and contains gamma oryzanol which has been suggested to have muscle building properties in horses.

Sunflower Oil - Sunflower oil is high in the essential vitamin E and low in saturated fat. It helps promote shiny coats.

Feed at the rate of 3 ounces by weight (one enclosed scoop) per day.

What People Are Saying

“I had this horse in my barn that belongs to a friend of mine. He told me he couldn’t get him to eat or put any weight on and asked for help. I took him in to my barn to see what I could do. After feeding oxyaide for only 7 days he finally would eat his hay and mag fat. After just 30 days on mag fat his ribs stopped showing and his coat got much shiner and slicker. I’m very impressed with this oxygen supplement as this horse loves eating it and he has done a total transformation in just 30 days. I started noticing improvement in just 3 weeks. I now feed mag fat to all my horses who need that extra kick of fat on them.”
