Has anyone ever used the 100x joint supplement? I usually buy Cetyl M but its been increasingly difficult to find. Like the amount of HA in the 100x and have had friends that love the GutX by them. Neither of the horses that it would be for have any real issues besides older horses (26 and 18) and they both run, depending on weather, 3-4 month. 

Very very littlre HA is absorbed through the GI tract. A jug of the 100X is about the cost of a legend shot given IV and goes exactly where you need it. Adequan series 2x a year is also a great option for those with no real issues. I pay 300 for adequan every 6 months, 

Thank you for the information! I should add they both get a set of adequan in spring, usually a legends shot and one gets stifles done yearly.  I was just trying to figure out something for daily use since I had such good luck with cetyl m in the past.
