Grand HA Synergy is rated 4.3 out of 5 by 29.
Rated 1 out of 5 by from Was hoping my horse would eat this I was feeding my older stallion Smartflex Senior pellets but he got to a point, during the winter, that he would not eat any pellets at all. He suffered a broken jaw and skull when he was about 5 months old, and we thought that maybe during the cold months, the pellets might be causing some sort of problem. He is a picky eater, but, he would eat his "treats" which are 5/8" packers cubes. So, I switched him over to the Grand HA Synergy. When I opened the bucket, the smell was not pleasant, and it took over a month before he would eat his daily ration with it in it. I had to start out with a small amount in the scoop, and slowly added to it, until he was getting a full scoop. Of course, just after I opened the 2nd bucket, he decided he wouldn't eat anything this was in/on. Not sure what I'm going to do now. Hopefully, the other horses will eat it!!!

Rated 1 out of 5 by from Horse wouldn’t eat it I have tried convincing my horse for a month to eat this supplement. He has never been a picky eater but this even with the flavor additive he won’t touch.

Rated 4 out of 5 by from Older mare doing well on it My lease mare is 15y, but has been jumped most of her life, and doesn't have the most perfect conformation. Since being on this supplement, we've found that she rarely cross canters b/c of her stiff back joints, and she seems much happier on the right canter lead and depart. I think the supplement has helped her joints and her health. She does eat it, although if not mixed well with pellets, there is some left lining the bucket. It is powder form and she doesn't lick it up, but it hasn't made her go off her feed at all, so I assume it's something she doesn't mind eating.

Rated 4 out of 5 by from Works great but.... I think this product works great. My arthritic horse with a bum knee looked and moved better than he has in a couple years. My lab started taking it too and he stopped limping right away and did really well. I got the neighbor to start her Catahoula on it and he stopped limping and looked happier. The problem is what seems to be side effects of the product. Horse got two extremely shelly hooves. Lab, pancreatitis. Catahoula, 3 weeks into taking it totally fell apart...allergic reaction? Eyes blood red and swollen and thyroid issues. Took everyone off the product, recovered. Feet improved, a ton of vet bills later dogs improved. So as much as I like this product I can't seem to separate the effects from the possible cause.

Rated 2 out of 5 by from My horse refused to eat this My horse is not picky about supplements but he refused to eat this. I switched to SmartFlex III Resilience Pellets.

Rated 4 out of 5 by from Marginal results for cost While the list of ingredients was what I was looking for, I was disappointed with results. I have to say- it is A LOT of powder. Horse is not a picky eater but had to entice with other ingredients in feed to get him to eat it. It was a hassle. Generally the Omega 3's should produce a nice shiny coat, was not evident at all. Joint relief was mediocre.

Rated 4 out of 5 by from Horse seems to have lost "creaky-ness" My horse has been on this for over a month, and i can feel the difference in his gaits. He has lost much of the "creaky-ness" he had when i bought him. This supplement seems to do a good job of supoorting his joints through the rigors of eventing. I am very pleased with the results only after one month!

Rated 5 out of 5 by from Good product Keeps my 23 year old roping horse going. He gets around like he is 10 years younger now.

Rated 5 out of 5 by from It Works I have a 31 yr old gelding I was "this close" to putting down. After muscle testing him, adding some supplements and Grand HASynergy, he is a new horse. Its pricey, but it works! It is a joy to see him run and buck and play again.

Rated 5 out of 5 by from An investment in recovery I've had my OTTB on this product for almost a month having stepped up from Smartpak Maintenance and am seeing the difference. For the first time since I got him in June he started bucking and playing like a colt. This is 10 year TB who spent 6 years racing and has arthritic changes, bone spurs and some bone chips in his ankles. I expect to see continued improvement!
