I use Riaflex Complete - it offers a slightly higher spec than Synequin (the one the vets recommend) at a third of the price! And I've had great results from it.
I didn't vote in the poll, but so far I've tried....
Cortaflex HA - made no difference what so ever
NAF superflex - minor improvement - would consider buying it again. Had to stop due to the cost last time.
and am trying Feedmark Extraflex ATM but only been using it for about a fortnight so far. It does have good levels of the right ingredients (I'm sure someone can explain what amounts of what you need better than I can) which is what drew me to it in the first place.
I used bluechip dynamic for a long time with great results
(as in alot free'er threw his shoulder etc),unfortunately cashflow will no longer let me stretch to that
.so have just put him on equiflex from vet vits,have heard great reports,but he has only been on it a wk so cant really judge,however he is on it as a prevention rather than cure,and if it supples his joints its all a bonus
QR- I used NAF Superflex. My horse (17yo) is on a maintenence dose all year round - 1 and a half scoops in the summer, 2 or 2 and a half scoops in the winter. The change is amazing, have used it for years. He used to be very stiff coming out his stable/ warming up.
Am just about to start my lad on Superflex to get him through winter. He is out 24/7 at the moment but has DJD in both hocks but is only 8.
Have tried Pernamax in the past but didnt notice much difference.
Last winter he was on human grade Glucosamine & Chondroitin, it was just a pain breaking up all those tablets each night, but it was certainly cheaper than buying equine added tax supplements and it did help him.
I use feedmark's ExtraFlex HA. I used to feed Cortaflex, but I changed over 6 months ago, as I discovered this is a higher spec and cheaper than cortaflex.
Was using Premierflex HA and rate is massively, however have just switched to Cosequin (available from vets only)
As I understand it the main variation that effects joint supplements is the quality of the other ingredients that facilitate the absorption of the glucosamine (normally chondroitin and MSM) On a molecular level chondroitin is made up of 'strands' and these strands can be short and fat and powerful, or long and sinewy and weak. I have been advised (by a vet who has a self confessed interest in the subject) that the cheaper joint supplements on the market often use these longer, less effective types of chondroitin- presumably to keep costs down.
Critically this means that although the tub says you are getting more chondroitin per kg than more expensive brands, the product is unlikely to be more effective because it remains less powerful
Sadly the only guideance he could give was to say that the open market is totally unregulated and only Cosequin and Synoquin are tested and researched, which is a regulation inflicted by virtue of being issued by vets
He may just be selling products for his clinic
but all I know is my horse is sound (after 3wks on this) for the first time in 9mths!
I didn't read the poll properly and answered other when I actually use Premierflex HA (well it is still early!). I've been using it through the summer and have been really impressed with it. I could feel the difference in my horse in the first week.
