    4-in-1 HA is rated 4.9 out of 5 by 52.
    Rated 5 out of 5 by from Really Works My horse is a very tall and stocky built Paint with very small feet for his size. He is 15yo and had become so uncomfortable with no riding, just turnout, he could only walk and had a visible limp. Thanks to 4 in 1 HA and Farriers Formula Double strength he is now running and bucking in the pasture! And requires no bute to be comfortable.

    Rated 5 out of 5 by from Best thing I've done for my horse Using the supplement wizard, Smart Pac created a supplement pac specifically for my horses needs. She has been receiving the 4-in-1 HA since I bought her a year ago. She is now 4 years old, has a beautiful coat, strong hoofs, stifle locking has improved and she has never had colic or any digestive problems.

    Rated 5 out of 5 by from 4 in 1 HA My horse Jasper was x-rayed for a mild lameness and it was found he has ring bone. I tried many supplements that he did not like. I called SmartPak and they were so understanding and sent me samples for supplements that would help him. Not only is the 4 in 1 have everything he needs, but he loves it! Yeah! He is feeling better and I am a customer for life. Thank you SmartPak!

    Rated 5 out of 5 by from Good Stuff :) I have a little 6 yr old Grullo mare who has a very mild lameness during tight circles to the right. X-rays and ultrasounds show nothing. At a loss with how to manage this, I decided to try the 4-in-1 HA. Honestly, I didn't expect to notice much of a difference...but, I was pleasantly surprised with the results. She is sound with very fluid movement. Also her coat looks amazing!

    Rated 5 out of 5 by from Really Works! I first obtained a sample of the product for my 22-year old Quarter Horse mare, Cheyenne (she is an extremely picky eater). She like it so I ordered the Smart Paks. She has been on the product for a littler over 30 days; she looks awesome! Her coat is shiny, her hooves, mane and tail look great. I would absolutely recommend this product!

    Rated 4 out of 5 by from Pleased so far! I have been using this product for about 2 weeks now and so far I have been pleased. My picky eater TB eats it right up! His coat looks fantastic and his hooves are already starting to improve. He seems to be moving well so far. I am hopeful that the joint products in this supplement will continue to help make him comfortable with more time on the supplement. All in all, I am very happy with this purchase! I love that this is a multi-purpose supplement so I don't have to purchase 3 different supplements.

    Rated 5 out of 5 by from Great Product I had been using Grand Complete which I really liked, but unfortunately my horse started leaving it at the bottom of his feed bucket. So I was paying a reasonable price for a supplement he wasn't actually eating! This pelleted formula has everything I want in it, and he actually likes the taste!

    Rated 5 out of 5 by from Great product for the picky eater We have been using this product for more than a year wanting a supplement that is not only good for the joints but also a good overall supplement. We tried this product with our upper level dressage horse who loves it. In the past she has been seen picking thru her grain and then spitting the supplement out or just not eating it at all when powder supplements where used so we needed a very palatable supplement and this one is. We love that it is pelleted as it blends right in and isn't messy. Give it a try, it is a good over all supplement for whatever discipline your horse is.

    Rated 5 out of 5 by from Keeps my senior horse moving We have been feeding 4-in-1 HA to our senior horse (25+ years) for a couple of years now. Prior to using this supplement, our senior mare experienced stiffness and soreness. This product allowed my daughter to continue to show in 4-H and other light riding. Our very picky eater will actually eat these pellets, unlike some other products we tried. We will continue to use this product for as long as we have a senior horse.

    Rated 5 out of 5 by from very happy I have nothing negative to say about this product. It suits the needs of my picky TB; he eats it and he looks great!!! I started him on an all-around supplement just because my boy was in his early teens and wanted him to feel good with the additional joint/HA support. He is 15y/o this year and acts like an 8y/o, plus my farrier says he has strong, solid feet.

    Rated 4 out of 5 by from Easy to feed, All My horses eat it! I ended up looking for a combination pelleted product because of too much waste with the powders. Some of my horses are a bit fussy and wouldn't always finish their grain & supplements. Also, because I sometimes need others to help out with the horse chores, making it easy was important, thus the 4-in-1

    Rated 5 out of 5 by from 4-in-1 HA My horse is young and very athletic. He is also a picky eater. So I love that he gets all the support he needs and gobbles it up! His coat is shiny, His attitude is happy and alert. He is calm and focused. Not high and strung out like some supplements make him, This product is definately a winner!

    Rated 5 out of 5 by from great product My horse has been on this product for over a year with good results. He is on it as a preventative, as he is a big boy and does a lot of jumping. As a result of this product his coat has really blossomed, and his feet have never been better. It is hard for me to say much about the effect on his joints because he was never ouchy or stiff to begin with, but at 14, he is not showing any signs of wear and I would like to attribute that to this product. I would definitely recommend this product to anyone. Finally, the pellets are always eaten, and because they mix right in with his feed I never have to worry whether he is getting the supplement.

    Rated 4 out of 5 by from One Happy Mini As a concerned horse owner AND a veterinarian, I studied the contents of joint supplements carefully before deciding to use this product on my 20+ year old mini mare. She is beginning to develop arthritis, but she is incredibly picky about supplements. This one is working out very well though! She actually likes it, and after just one month, she has a noticeable spring in her step and is back to keeping up with the other horses.
