Product Overview

Which horses benefit from pituitary support?

With advances in management and technology, senior horses are living longer than ever.  Unfortunately, the results of stress over a long lifetime can have an impact one of the structures responsible for normal hormone production – the pituitary glands. By affecting your horse’s endocrine function, issues with pituitary health put stress on the immune system, cause loss of muscle tone, and lead to poor shedding.

For horses with pituitary challenges, the specialized formulas in this category may be ideal as part of a comprehensive management program designed with your veterinarian. In addition to helping maintain endocrine health, these products include targeted ingredients to help address the areas of health most affected by pituitary dysfunction.

SmartPituitary Senior® Pellets is rated 4.3 out of 5 by 277.
Rated 4 out of 5 by from Seems to be helping I started my PPID 25 year old gelding on this about a month ago, and it seems to be helping with his overall attitude and shedding. I plan to keep him on it for now. My only complaint would be that it does have an odor, and he really doesn't like to eat it, even when mixed with his feed.

Rated 4 out of 5 by from Worth a try! I don’t really know how to rate this product yet as I’ve only been using it for a month (+]. So far I haven’t seen any outward change in my 28 year old cushings mare with neurologic problems. Perhaps it’s not what she needs, but I thought it worth a try.

Rated 5 out of 5 by from This stuff works! My horse was diagnosed with Cushings last summer. Even with his daily dose of Prascend, he continued to do poorly- tired, no appetite, depressed, poor attitude. After about 2 months on SmartPituitary Senior® Pellets, I have my former horse back- perky, friendly, good work ethic. I wouldn't quit using Prascend prescription drug, but I do recommend supplementing with this fine product/

Rated 5 out of 5 by from Great product for my horse My 15yr old mare's Cushing symptoms seem to be subsiding after only 2 months on this product. She can be finicky, but she eats it right up!

Rated 5 out of 5 by from Seems to have worked I bought this for a horse showing the early signs of Cushings. It does seem to have helped (hard to tell with cold temps and winter coats).

Rated 5 out of 5 by from Worked wonders I have had my senior mare (24 YO Quarter Horse) on this supplement for almost a year now, but I began to see favorable results within the first 3 months!! I am more than pleased with the product!! She has blossomed while using it. She has more energy and stamina than she has had for years. She struggles with Heaves as well as Pituitary symptoms, but the Heaves symptoms are more easily controlled now that she is on SmartPituitary for Seniors. I believe the antioxidants and other ingredients have given her entire system a boost. Specifically, I noticed a vast improvement in her topline within 3 mos on this product. She is shedding her (very wooley) winter coat normally and has fewer problems with skin infections. Full disclosure: she was prescribed Levothyroxine by our vet for her pituitary problems but he advised that the medication alone would not resolve all her issues and suggested a supplement. The SmartPak advisors suggested this one and I am very pleased with the results! It is also very easy for barn staff to administer which is very important to ensure she gets it consistently. I love SmartPaks!

Rated 2 out of 5 by from Horse wouldn’t eat Unfortunatly my horse refused to eat the pellets. I tried several different things to entice her, but she took one sniff snd refused to eat.
Date published: 2020-12-07
Rated 2 out of 5 by from Pony and Horse won’t eat I bought this for pony and horse that are both diagnosed with Cushings. Both are feed hogs, and neither would touch their feed with this in it. I tried adding things to make it more palatable and they still wouldn’t touch it.
Date published: 2020-11-28
Rated 5 out of 5 by from Major improvement so far My 26 yo mini horse has been getting really drug down by the winters the past few years getting respiratory infections, winter laminitis, etc. I’ve been testing out different supplements and nothing has seemed to help. My vet recommended trying this supplement. He wouldn’t eat it at first but after a few days he warmed up to it. He acts like a 10 yr old again. We’re already into the point of winter where he starts getting sore and depressed and he’s as lively as ever right now, feeling good! Will be interesting to see if this keeps him that way. I’m sold on it so far, just ordered some more.

Rated 5 out of 5 by from Impact My mare was diagnosed two years ago with PPID/Cushings. I put her on the smartpituitary within two months and she has done very well! I believe her good health at 23, with Cushings, in part is due to this supplement. Thanks!

Rated 5 out of 5 by from RC is responding very well to this product My 25 year old American Saddlebred is doing great on this product. Amazing difference in how he feels.

Rated 1 out of 5 by from My gelding won’t eat these It’s been a week of trying to get him to eat it. It does matter what or how much bulk I try to mix it in with, he won’t eat it. Dewormer seems more palatable. I think smartpak should take the picky eater symbol of this one.
Date published: 2020-10-16
Rated 1 out of 5 by from Hog of a mare won't eat these! In the 29 years I've had my mare, I've hardly ever seen her refuse a food until now. She won't even sniff her bucket, she turns her head and walks away from these. Sad, because I was hoping these would help her.

Rated 5 out of 5 by from Works well! I bought 2 months ago and it has shown great progress for our horse.
Date published: 2020-09-05
Rated 1 out of 5 by from Apparently, not tasty I don't have a picky eater, but of course Prascend and PPID do impact horses' appetites. But after my horse, who usually eats everything, stopped eating his grain, I finally thought to b break out each well of his Smartpak and figure out if it was one of his new supplements that was the problem. Sure enough, it was the Smartpituitary. He gobbled everything else up. So alas, something in here must be off-putting.

Rated 5 out of 5 by from Really helped my horse I bought this a month ago and it has helped my older horse who have had chronic diarrhea off and on for several years. I have tried everything, and my horseshoer recommended this product and after a month, she has solid normal stool

Rated 5 out of 5 by from Works! Ace, my 36 yr. old Appaloosa had not been shedding well in the last few years and our vet was positive that he has Cushings. I found smart pituitary senior and started him on it 3 months ago. His coat was extremely thick and it was already late spring and he was not shedding at all. I doubled the dose the first month as I was worried about warm weather coming and him still having a full winter coat, it worked and he started to shed. It is now mid July and he is 90% shed out. He has also put on weight and has stopped the nasty habit of eating his manure. He is acting more like himself, big appetite and his usual energy trotting in and out to pasture.
Date published: 2020-07-17
Rated 3 out of 5 by from Not sure I purchased this and am not sure if it was helping, I didn't see any improvement. I've had him on the Smartpak Chastberry for almost a year, thought I'd try this. He wasn't fond of the smell or taste at first, will eat it now. I'm not sure what I should do, he is on Prescend.

Rated 2 out of 5 by from jury is still out My gelding ate the pellets, sometimes he's picky. This product did not help him she'd out. I'm having my vet out in a week to examine him and decide wether or not to continue using this product.

Rated 5 out of 5 by from Great customer service! I have been buying Smart Pituitary Senior Pellets got several months. It really seemed to help with my 33 year old mare’s coat and body condition. Unfortunately, this past Monday my mare crossed the Rainbow Bridge. When I called SmartPak to cancel my subscription they couldn’t have been any more helpful or kind. What a great company!!
Date published: 2020-06-19
Rated 1 out of 5 by from Not Picky Eater approved We bought this for our older donkeys that weren’t shedding as well. Our donkeys eat very low quality hay and just about anything we put in front of them. However, they would not go near their grain bowls with this product. I thought it was odd but not unlikely until we tried to feed the remainder of the product to another pony in the barn and this pony would also not touch it. It’s too bad as it seems it would have been a good product.

Rated 5 out of 5 by from Worked better than I hoped for! Bought this for my 23 year old mare that has been showing signs of Cushings, long coarse hair, tender feet and loss of topline. Within a week of starting this supplement she started to shed and after a month she is mostly shed out and her coat is good. Feet are less tender and topline has improved. I will keep her on this as part of her diet going forward.

Rated 5 out of 5 by from Very fresh I bought this 2 months ago to help my now 36 year old Appaloosa. He has Cushing and his coat looks like a wooly mammoth! He had not started to shed and I was very concerned so I started him on smartpituitary senior and am pleased to say it is helping him to get rid of his very long coat. I will report after another month of using it. It is also very palatable as he gobbles it up everyday in his mash.

Rated 5 out of 5 by from Great for my retired mare! I bought this for my 23 year old Holsteiner Mare, who is now semi retired. She still teaches smaller kids to ride and jump cross poles and is still very active. I noticed in the last 3-6 months she started to get a bit of a sway back and this product was recommended to me. She has been on it for the last 2 months and I can see a huge difference in her back, coat, hooves and all over all appearance! Highly recommend!

Rated 5 out of 5 by from Obviously this is anecdotal evidence, so take it with that in mind... Last year my 31-year-old horse took twice as long to shed his haircoat as usual. eACTH test for PPID the previous fall was normal...planned to do a more in-depth test (TRH stimulation) if he continued to have problems. Started him on SmartPituitary in the mean time, why not. This year he shed out beautifully and definitely does NOT look his age! Whether this is due to the supplement or not, I will definitely be keeping him on it! He eats it just fine too (but would eat anything).

Rated 4 out of 5 by from I have been using this product since the end of December and I can see where it helped gain some wait back and keep her healthy throughout the winter.

Rated 5 out of 5 by from Works for my horse My 21 year old Arabian has Cushings and hadn't shed out for two springs.I started him on SmartPak Chasteberry and Vitamins for a few months and it appeared not to help. So this last fall I changed him to SmartPituitary Senior, Vitamin E, Selenium, Turmeric, Magnesium, and other trace minerals. This spring he finally shed out and lost most of his hair, I basically just had to trim his legs and fetlocks. He looks great and finally losing weight. Because I am so impressed with this product I will be starting SmartPituitary Senior on his his pasture mate, 21 year old Quarter horse.They have been together all their lives and I believe it will help his immune system.
