Question: Will Lubrigen Joint supp be safe for my 18 year old mare that is prone to obesity? She gets Bermuda hay, couple handfuls of Alfalfa and some grass blend hay pellets. I have to be very careful with her and so many of these supps have high Alfalfa, corn, and fats, etc. Thanks!


Dr. Kellon: Lubrigen will not cause your horse to gain more weight, but if her easy weight gain is related to insulin resistance the glucosamine could make the insulin resistance worse.  It would be a good idea to have her tested. If you want a good joint supplement without glucosamine try Equi Flex.
