Glucosamine and Chondroitin supplement

Since Thelma's 23'rd birthday is just around the corner I am looking more seriously at supplementation for her joints.
She has never been stiff or off, but I would rather start her on something now, and avoid issues later.


I have access to Glucosamine/chondroitin pills in human doses at wholesale prices and was wondering if this is something that would be okay to put her on. And if so, what dosage?

Forgot to add that she is already started on pure MSM.
The tablets I am thinking of are mixed glucosamine and chondroitin. They are 1500mg glucosamine and `1200mg of chondroitin, if that changes anything.

I've read that to really do a bunch of good, there needs to be 9,000mg of glucosamine, daily, in the diet.
However, Lacey's on a supplement ( Majesty's Flex Wafers - Horse Treats from SmartPak Equine ) that's only 2,500mg of glucosamine and there has been improvement with that (she's also barely arthritic). I'm thinking of bumping her up to two "wafers" a day though, just to see it she improves even more.

I don't know why your pills wouldn't work, but the only thing I can think of is that there may be differences in the way horses and humans absorb things internally, and since the pills are for humans... But I don't know, that's just a guess.

Good to hear. So if I was doing 9,000mg then that would only be 6 tablets a day. The bottle is 900 tablets, so it would last me 150 days. And only $25 a bottle and then $15 for her MSM which will last me a very long time as well. I think that she'll be in great shape for summer riding.

Lots of people don't know what MSM is or does, but I heard that it is great alone or in conjunction with Condroitin and Glucosamine, so that is my goal.
MSM in the Equine World <Tells about MSM.

I figured that it would be fine to use even if it is marketed for humans and there are no additives, but I wanted to make sure first.

Thanks for the info. I am very excited for this summer!

Geez! You wanna send me one of those bottles when you send that flymask? I'll pay of course.
However, that might push shipping into the exorbitant range... haha
