How to get your horses coat sleek and shiny?

I have a healthy 6 year old thoroughbred mare and i do show jumping with her and dressage. I have noticed that in a lot of the competitions the other horses have shiny sleek coats. i was wondering how they achieve that in there horses. Do they achieve the horse's sleek shiny coat by clipping there coats or is it because of supplements they give them, and if so what supplements do they give them. I would just really like to know how to get my horses coat to be sleek and shiny.
