I am not a big fan of orals at all, orals have not been proven to be effective. Many studdies have been done on orals, that show that they are a crap shoot.
The reason being is because Oral Supplements fall under the Equine Nutrition category, where rules, testings and regulations are lax. So Companies can say that their product has "This and this" in it, when in reality, it just may not at all have that ingredient. And/Or Companies can say that "This much of this ingredient" is in their product, when there could be only 1/8th of what they are claiming.
Also, studdies show that the process orals have to go through, is quite long - from the mouth, into the stomache, into the digestive tract, into the blood stream - each process that the oral has to go through, breaks that dosage down, so that by the time it gets to the area needed, only a very small amount gets there, while the rest goes out the back door. Results with Orals, take up to 6 months - and orals are a "C.rap shoot" - they may, and they may not work.
The price of Orals as well, is costly. You're spending your hard earned money on a product, that just may be what the company states it is...or may not be. On a product that just may, or may not work. And, who knows if your horses system can utalize what they are being given. That's why we see some horses with results, and some without.
With Orals, you have to ensure that the dosages meet the minimal requirement to be effective - that is, if the product is stating the facts. For example, you have to have at least 10,000mg of MSM. Hyaluronic Acid, you need at least 100mg's, preferrably 200-500mgs. Etc, etc, etc. There are very few orals out there, that even meet measurement requirements.
That's when NASC came into the picture. They are an organization who studdies products on the shelves, to ensure that they are what the company states they are and has what the company claims they have in them. If I had to go with an Oral, I wouldn't purchase anything without the NASC stamp of approval that you'll find on the container.
Intramuscular Injections are, in my opinion, the better option to take. Now, don't mistake IM's with actual joint inections - they are two completely seperate things. IM's, are a joint product that goes directly into the horses blood stream, through injection into the muscle in the neck of the horse.
IM's, like Adequan, Legend, Polyglycam, Glucosamine and Pentosan. These products fall under the Equine Medical Category. Where rules, testings and regulations are very strict and closely followed. So the product is what the company states it is, and the product has exactly what the company states is in it and does, exactly what they state it does.
IM's, go directly into the blood stream and show results within 48 hours. The process is quick and to the point, and the full dose goes direclty to the area needed. No long process for this stuff - wham bam, done.
My TB gelding has arthritus in his right hock, and I did the oral game. He would still be stiff, sore and would show signs of pain *he will lift the leg up and hold it for a few moments and place the leg down*. He reached short with that leg and would show signs of arthritus after flexion tests. My vet gave him 1 injection into the neck, and the results he showed were fabulous. He went from 21 to 10 in the first 48 hours. He was moving beautifully, he stopped lifting the leg, he was frisky and feeling good. I was hooked. He has been on Adequan for over 1 year now.
You can purchase Adequan from Smartpak, a 10 Month Dose Vile for $376.95. As my Vets state, it's the best of the best.
Let's look at SmartPaks Resilliance III Pellets.....yes, it has the minimal requirement of msm at 10,000mg, which is good. It is NASC stamped, which is great because that prooves that it is what the company states it is - but it's still a feed through. That costs $59.95 for one month. For 10 months, you'll be spending $599.50. Ouch. That's too pricey for my taste, for a product that may, or may not work. For a product that still has to go through the oral process to get to the area needed.
I would highly recommend going with an IM. You'll be saving money, you'll be giving your horse the sure thing/best of the best, you can be assured that the full dose of the product is going to the needed areas and the process is much quicker. Giving my horse Adequan, I don't have to give him anything else for support via joint wise.
