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 295.
Rated 5 out of 5 by from Great Supplement For Old Horses I have a 31 years old thoroughbred, retired eventer. He has Cushing's, he is on medication for it, and is being fed 8lbs senior feed per day and an abundance of hay, but still his coat/body was looking rough. I purchased this supplement a little less than 2 months ago, but already can see it is helping him. His coat is looking healthier and his quirky mannerisms are back. He will be staying on this.

Rated 4 out of 5 by from Doing well! Fluke has been on this for a little over a month and people have commented that he appears to be gaining weight, which is what he needed to do. He is a very picky eater, but he loves the pellets. So happy they seem to be working.

Rated 5 out of 5 by from Amazing products My horse has been on this for a year and the results are amazing. His coat is stunning. The vet always comments at his annual checkup on how good he looks and feels for a 28 year old. He looks and acts like a much younger horse.

Rated 4 out of 5 by from I'm hopeful that this works!! I bought this product for my horse with Cushings Disease as he cannot take any pergolide products since it makes him sick. I believe it has made a difference for him. He will be tested again in a few weeks. I hope his blood work is improved.e

Rated 5 out of 5 by from I have my horse back! I can't believe how well my 23 year old Haflinger is doing on this supplement. He has had Cushings disease for 3.5 years now and is on Prascend. He would still keep winter hair all year and need regular body clipping in the summer to stay cool. And his skin was just over all more dirty and he acted older :( After being on this supplement for 3 months, he has shed the hair (his beautiful palomino dapples are back!!!) and he is acting like his old self again. I am so excited about the results!! My only complaint is, he won't eat it on his own. I tried to mix it in with different grains for the first couple of weeks and I couldn't fool him. So I started grinding it up with a spice grinder, adding a little oil and water to it and putting it in a large syringe and giving it to him like a medication. He is a good boy and will take anything I give him.

Rated 2 out of 5 by from Smells really bad. My first complaint is this stuff smells like a combination of a 200 year old basement and dirty gym socks. My horse hates it so much I have to disguise it with molasses and basil. Not good for a metabolic horse. After 1 month I cannot say I see anything more than a marginal improvement with this product. Also, this 28 day supply is kind of a rip off, considering all other products from other companies are a 30 day supply. The auto ship is set up poorly. I've just used my last SmartPak and have nothing for tomorrow. Auto ship does not allow for 3 day weekends or shipping delays. I don't think I'll be continuing this.
