How many scoops in the 2.9 tub?

Answer by ChewyFeb 11, 2021
The 1320 gram (2.86 pound) container is an eighty day supply based on giving one level scoop per day on long term administration. The amount of scoops varies depending on the size of the horse and whether it is the initial administration period or the maintenance period.

29 year old retired race horse and brood mare

I started her on this when her gait was getting choppy about six years ago at age 23. She has been moving well ever since.

Excellent Product

Two out of our four horses use this product. We were so impressed on how it made our 17 year old boy feel that we started giving our 19 year old after we bought

Two out of our four horses use this product. We were so impressed on how it made our 17 year old boy feel that we started giving our 19 year old after we bought him. They both have responded well to it so well that now they both kick up their heels in the arena. It's so good to see.

Amazing stuff. Wow. Love it!! So happy

All I can say is WOW! I started my mare on this on August 1 and a week later amazing results. I Bought a new mare with arthritis in hocks and I trail ride

All I can say is WOW! I started my mare on this on August 1 and a week later amazing results. I Bought a new mare with arthritis in hocks and I trail ride. I was thinking I may have to give up my mare to another home as I wasn’t able to ride her without limping and stumbling. The vet recommended this product as he has his own horses on it. I tried previcox the night before and then right before riding with limited results. I added this supplement and within a week I did three hour trail ride that was quite rugged. I kept holding my breathe on the steep hills and not one limp. She even cantered which she was never willing to do. The vet also recommended hoof boots for her and fly wraps to keep stress off the hocks. All of this is helping Memphis to move without pain. I still can’t believe a supplement could make that much of a difference but it did. I know they say that the time it takes to show changes varies but for me it was super quick. Vet also said once you put them on this supplement don’t take them off. I plan on doing just that !!

Noticeable Improvement

I have two horses, a boy and a girl. The girl has navicular and was having chronic lameness issues at around 13 years old. I put her on this, and wow did it make

I have two horses, a boy and a girl. The girl has navicular and was having chronic lameness issues at around 13 years old. I put her on this, and wow did it make a difference in her! All the soundness/stiffness issues went away (it wasn't just my imagination, the trainer noticed it as well without prompting). At around 15 years old, the girl had what turned out to be a hormonal meltdown, but as part of trying to figure out what was going on with her, I pulled her off it. Wow, did I notice a difference in her soundness and stiffness when she wasn't on it (not in a good way). She's back on it (along with Regumate to deal with the hormones lol). The boy horse (technically a large pony, but he has 'horse' status for his efforts) is 23-ish and he went on it about a year ago. I didn't/don't notice the difference with him like I did with the girl, but I keep him on it. I suspect if I took him off it, Then I would notice the difference. They both eat it, including the picky eater girl. Another trainer from the first one (who noticed the difference unprompted) recommended the product, and when I asked the vet about it, she recommended it as well. My dog is on a dog version of it as well now.

Works wonders for my mare.

I have a 25 year old QH mare who has been on this on and off for the last 6 years or so for mild arthritis. I took her off of it for 2 years for financial reasons

I have a 25 year old QH mare who has been on this on and off for the last 6 years or so for mild arthritis. I took her off of it for 2 years for financial reasons and she earned the nickname "rice krispies" because her joints were always snap, crackle, popping whenever it got cold. I can see a huge difference in her demeanor and movement when she's on it, so it's worth the cost. I have tried the basic cosequin for her (because it's cheaper than this one) and it just didn't work as well. But this version with the ASU is incredible - I have always been so impressed with how well it works that I ended up getting the canine version for my older dog (and had great results there too)

Takes a while to assess effectiveness

Just started him on them loading dose two weeks ago. We will have to see how much it helps Arlo with his arthritis..
