Rated 5 out of 5 by from A Supplement That Truly Works I have been using Senior Flex for about three years, but just switched to the Senior Flex H/A. I did a lot of research in equine medical journals about the ingredients before putting my horse on this particular supplement. It was a good choice, but now that he is getting the HA I am even more pleased with the results. His stiffness on one side has decreased and he is clearly more comfortable in general. Highly recommend. It's pricey but worth it.

Rated 5 out of 5 by from Good value My older horse seems to feel pretty good. He hasn't been on this product for very long, so far so good.

Rated 5 out of 5 by from Love it ! I have a retired Appenix that has pretty bad back legs ,he doesn't go anywhere fast ,he isnt rideable so enjoys his days in pasture .The last meds he had seemed to work but not amazingly as I'd hoped . I have a slight incline on the lower half of my pasture so he never goes there its to hard to get up which is really sad the incline is pretty mellow ...Anyway fast forward to a couple weeks on this stuff & WOW not only is he back to enjoying the lower pasture he's runs back up it when it's time to eat or get snuggle snacks lol . I really wasn't sure about this stuff but I'd highly recommend it seeing how my older horse is so much better now :):):)

Rated 5 out of 5 by from Marked improvement of my senior! I put my 20+ year old (kill pen save) mare on this a couple months ago. She is noticeably moving better and seems so much more comfortable. I felt like she had some sacreolitic issues (never diagnosed) and she was quite stiff but she's retired so I just wanted to make her comfortable...thought I would give this a try. I am sure she's feeling better, she trots and canters on her own out in pasture which she hasn't done much of for a long time. I will definitely continue!!

Rated 4 out of 5 by from Good supplement! I bought this for my senior barrel horse and I can't definitely tell he feels better. He is very picky but he seems to do okay with this supplement.

Rated 5 out of 5 by from The best I bought this supplement in May and tried on my horse who is 19 years old. She had a horrible accident when she was 7 and sliced her hock down to the bone. She has been doing well but when I started this product I saw a difference and felt a difference in her movement riding. She is much more willing to move while riding her. She now moves like she did before the accident. She will be on this product forever.

Rated 5 out of 5 by from more relaxed and forward my acupuncturist commented that my horse seemed stiff through the hock area and might need injections down the road as I was having trouble with lead changes. he now does his lead changes again and is forward and comfortable after using this product for about a month

Rated 5 out of 5 by from He likes it! After using another joint supplement for a couple of years, my 30 year old Thoroughbred gelding was refusing to eat it. After doing a little research, I decided to switch to Senior Flex H/A and am so happy I did. He loves these pellets and he is moving well, dancing down the driveway on his toes and with a gleam in his eyes when we head out. He is suspicious about any "new" additives to his feed and will not eat anything in powder form, so I'm pleased that he didn't hesitate to try this supplement.
