I use it and love it. Currently I use the OHS Grand which includes biotin, vitamin/mineral additive, rice bran and a digestive additive (probiotic). I also have her on a high fat (with black sunflower seed) feed and lots of wonderful pasture and hay. I also groom on average 4 times a week...so who really knows what makes her look good (dont look at her avatar pic..old and icky). She is on her first month of being on this regiment..so we shall see about her weight, feet and coat...see if it improves even more.
