Product description

Horse Guard is the most highly concentrated equine vitamin-mineral supplement on the market today. A mere two ounces a day ensures your horse will get all the critical nutrients typically missing from hay – including 3 mg. of organic selenium.
Vibrant health is the result of many things, nutrition being the cornerstone. Horses, unlike humans, have very limited food sources – most of which are from the local area. Because of this they are much more prone to deficiencies caused by the deficiency in local soils and by the loss of vitamin content with feed storage.
Reformulated to included 1,500 IU of Vitamin E per dose!
Feed 2 oz per day,per 1,000 lbs. (Scoop included in Bag)
A 10 lb. bag of Horse Guard is an 80 Day Supply for a 1,000 lb horse
A 40 lb. bag of Horse Guard is a 320 Day Supply for a 1,000 lb. horse
A complete vitamin-mineral supplement helps to ensures complete nutrition and provides for all body functions.
Why is Selenium Important?
Selenium has several roles in horse health, but the most well-known is as a key element in antioxidant defense, which makes it important in every cell in the body as well as in immune defense.
The body produces radical oxygen metabolites (ROM) as a normal consequence of oxygen metabolism. Selenium-requiring enzymes such as glutathione peroxidase (GSH-Px) neutralize ROM, rendering them harmless and protecting cellular machinery from damage.
Other basic processes requiring selenium for normal function include growth, disease defense and reproduction. Selenium-supplemented foals are known to grow better than Se-deficient foals, possible because a Se-dependent enzyme is needed to activate thyroid hormone.
In addition, both males and females require selenium for reproductive function.
Exercise increases oxidative metabolism markedly, which results in mobilization of tissue selenium to meet increased antioxidant demand. This explains why performances horses and human athletes have greater selenium needs than non-athletes.
Is Organic Selenium more or less toxic than inorganic selenium?
Although more digestible than inorganic selenium, organic selenium is actually much safer to both horses and humans. The organic selenium compounds that plants and yeast produce are nature’s way of providing a potentially toxic element in a safe form. Selenoamino acids are absorbed from the gut via amino acid pathways, which necessarily limits excessive uptake.
In contrast, inorganic selenium (selenite) is passively absorbed, which allows rapid and unregulated uptake of toxic levels of selenium. Organic Selenium is also much safer to handle by those mixing feeds. Sodium selenite is extremely toxic because it is absorbed through the skin. In contrast, the compounds of organic selenium are not absorbed on contact, which increases safety against the most common selenium toxicity problem: exposure to human skin.

Feeding Horse Guard to a Cushings Horse
The goal is to build a diet for your horse that is low in NSC. Choose hay that best suits your horse’s needs. For a horse that has a hard time maintaining weight, feed a warm-season grass/alfalfa hay mix. A heavier horse will do better on warm-season grass hay.

Great supplement
I bought horde guard almost 2 months ago after buying my 7 yrs old quarter horse gelding because the previous owner told me he was always on it, he doesn’t get grain at all, he loves his supplement pellets all by themselves in addition to the hay, he looks amazing! Coat is shinny, over all super healthy

Will continue buying!
I have been very happy with this supplement. I think my horse was lacking vitamin E. This greatly i proved his coat and he seems happier overall. Glad that probiotics are also included along with many other vitamins/minerals. Price is affordable, easy to get shipped, also like being in pellet form.

Very strong vitamin smell
My horse refused at first to eat her grain with this added so I started a very small dose and mixed well then added more after a week. Very strong vitamin smell.

Has really improved my horses overall condition
My 16-year old WB / TB cross lost a ton of weight and body condition in her first 7 months in Texas, after moving from Southern California. I contribute the weight loss to change in weather, and the first barn I had her at simply wasn’t feeding her enough. She is shod only in the front, and her back feet started falling apart to the point where I considered putting shoes on the back. I moved her to a new barn, added Horse Guard and Nutrena Empower Boost to her diet, and the results have been incredible. Her coat is shinier, she’s put weight on, her hooves are so strong that I’m considering taking her front shoes off, and, she is happy! I think her progress was a combination of things but I will definitely not be taking her off of horse guard. I highly recommend!
