I'm sure this is a foolish question, but really, what is the difference between MSN and glucosamine?
I'm looking to put both my horses on a joint supplement as a preventative measure. One is a very large, 17.3hh Trakehner gelding, 7 years old, the other is an almost 4, 16hh, thick Holsteiner who is just getting started this week (and thinks life sucks )
Should I be looking for a supplement that has both of these in them? Something with a higher concentrate than the other?
(any supplement recommendations?)
