I think the oral supplements DO work
I feed Hylagen 60 from United Vet Equine.
Of course you have to feed the 'loading dose' which is basically a double dose for about the first 2 weeks - 30 days.
I have fed Hylagen 60 for several years (probably 9 years).
It has the required 10,000 mgs per day (per 1000 lbs of body weight) of glucosmine, and MSM.
It also has 60 mgs of HA (hylaronic acid).
I found the 2 oz daily dosage to be the 'best bang for my buck' as far as minimum amount fed daily, containing maximum dosage of the necessary ingredients.
I believe in supplements, BUT, they cost money, and are a long term, DAILY commitment.
That's what makes them work properly.
Just an FYI, I never had good luck with cosoquin with my dogs.
That particular product just did not work well for me.
Be careful with Oral Supplements.
I am not sold on them, and I have never seen results due to them to be honest - some swear by them, others think they are a waste of time.
I have read many studdies done on oral supplements, that show that they are a crapshoot.
The reason why Oral suppelements may, or may not work - is because they fall under the Equine Nutirtion category, where rules, testings, regulations and studdies are very lax.
So a company can say that "This" product is what they say it is, without any consequenses, when in reality, it just may not be exactly as they claim it is.
A Company can say that their product has "This" ingredient in it, when in reality, that ingredient is no where found.
Companies can also say that "this much" of "this" ingredient is in their product, when in reality that dosage may be noooo where near what they state there is.
Because - rules, regulations and testings are very lax in that field of the equine world.
Studdies also show, that the process that dosage you give your horse in their feed, really breaks down quickly in the horses system,
So that by the time it gets to where it needs to be to do its job, it's quite minute in compareson to the origional dosage given.
Personally, I think oral supplements are a waste of money and time. You are literally flushing your $$ down the loo IMO.
So, lets look on the other side of the scale......where Intramuscular Injections are applicable.
IM's like Adequan, Legend, Polyglycam, etc - fall under the Equine Medical Category, where rules, regulations, studdies and testings are very strict and closely followed.
So, companies like the makers of Adequan, have go to through hoops to get that product on the market, so it ends up being, exactly as they claim it is.
Also, studdies show that when you inject the solution into the horse directly,
That the product goes directly to the needed area's, nothing breaks down, nothing is wasted, nothing gets lost somewhere in there...
It does what is stated it does, and you are giving your horse the full dosage.
My TB has arthritus in his right hock, it's not that bad, no where near where one would think a very athletic 22 year old TB would be - and oral supplements did diddly squat for him.
Stiff, hard to get infront of my leg, couldn't get him to track up,
Resistant - after the first Adequan IM, I saw results right away. Improvement in his movement and willingness to do so.
I would far rather invest my $ into the sure thing, than a product that may, or may not work.
Orals work on some, and do not on others.
I'd rather invest the money I obtain through hard work, on a product that has far better results and is the sure thing than playing the guessing game with orals.
I deal with United Vet Equine because
they adhere to NASC standards. NASC
I would rather first see if the less invasive
route of an oral supplement works, BEFORE I go the more invasive
route of injections.
There can be a lot of risk involved in giving (perhaps) monthly injections, as well, oral supplements tend to be less costly.
Different strokes for different folks, but it can be a good starting place with an older horse,..,
And might be all you need as a preventative
I also will add that I discussed both options with my vet first,
And we agreed a good starting place for my older gelding was an oral vs an injectionable (injectables also may, or may not, work).
His opinion was oral first, then step UP to an injectable if the oral isn't effective.
