(Enclosed measure approximates 1 oz based on density of product.)
Adult Horses (900-1,100 lbs): Provide 1-2 oz daily.
Vitamin C is a well-known antioxidant that has been shown to aid in reducing joint cartilage degeneration and
decrease susceptibility to infections.
Calcium is a micromineral found in highest amounts in bone and teeth. However, it also has important roles in
muscle contraction, cell membranes, blood clotting, enzymes regulation, and hormone release.
Phosphorus (P) in bones not only provides structural support for the skeleton, but it also acts as a reserve of
P for other bodily functions. Phosphorus is important in cell membranes and in reactions requiring cellular energy
and also helps form the backbone of DNA and contributes to the pH and electrolyte balance in body fluids.
The minerals calcium (Ca) and phosphorous (P) play a major role in proper growth and development of
the skeletal system in horses.
Magnesium is a vital macromineral, and it is becoming increasingly recommended by veterinarians for various
treatments in the horse. Magnesium helps protect against inflammation and free radical damage. Magnesium
also neutralizes stomach acid and is a common ingredient in antacids.
Potassium (K) is a macro mineral commonly referred to as an electrolyte because it helps maintain the body’s
acid/base balance and hydration status. The amount of potassium in the diet of HYPP horses must be closely
Methionine is an essential amino acid, meaning it must be provided in the diet since the body cannot create
enough of its own. Methionine can be converted by the body into another sulfur containing amino acid, cysteine.
Lysine is an amino acid and the only one for which a requirement in the horse has been established by the
NRC. It is an essential amino acid. Lysine is also a limiting amino acid. This means if it is not present in adequate
amounts it limits the body’s ability to make protein. Lysine is important in the formation of collagen. Lysine
deficiency may result in immunodeficiency.
Sulfur is a macromineral and an essential constituent of several amino acids (methionine, cystine, and cysteine)
as well as the B vitamins biotin and thiamine, and a number of other important molecules such as insulin,
taurine, and chondroitin sulfate. Therefore, sulfur serves major structure and function roles in the body. It
is a component of proteins such as enzymes and of connective tissue such as hooves, bones, cartilage, tendons
Choline is recommended for supporting a healthy nervous system; has indications for concentration, motor
behavior, memory and muscle performance and prevents fat build-up in the liver.
Zinc is a micromineral involved in over 100 enzyme systems ranging from connective tissue formation and antioxidant
protection to carbohydrate metabolism and immune system function. It is most recognized for its role
in healthy skin and hooves.
Manganese is a micromineral essential for bone formation, growth and reproduction. It is also essential in carbohydrate
and fat metabolism. It plays an important role in young, growing horses as well as active performance
Copper is a micromineral required for production of normal connective tissues. As a component of many enzyme
systems, it is also involved in making iron available to the body for blood, in producing skin and coat pigments,
in proper nerve signaling and in repairing antioxidants. Low copper levels in mares and foals have been
implicated in developmental orthopedic disease (DOD) including osteochondrosis (OCD).
Glycine is one of the non-essential amino acids and is used to help create muscle tissue and convert glucose
into energy. This compact substance plays many essential roles in the body, makes up 35% of the protein collagen,
is a key component in many metabolic reactions, and has a modulating effect on the immune system.
The Vitamin B family is made up of several compounds that serve many important roles in the body: protein, fat and
carbohydrate metabolism; energy production; proper nerve cell transmission; and cell reproduction and division (especially
rapidly dividing ones such as red blood cells). B vitamins include thiamine (B1), riboflavin (B2), niacin (B3), pantothenic
acid (B5), pyridoxine (B6), folic acid (B9), and cyanocobalamin (B12); choline, biotin, inositol and others are
sometimes referred to as B vitamins. For most of the B vitamins, microorganisms in the large intestine make all the
horse needs. Only thiamine and riboflavin have NRC dietary requirements. However, research suggests B vitamin supplementation
may be beneficial to stabled horses with little access to fresh pasture, heavily exercising horses, pregnant
and lactating mares, horses with GI conditions that may interfere with normal gut flora, and any periods of stress (injury,
illness, shipping, old age, etc.), normal gut flora and any periods of stress (injury, illness, shipping, old age, etc.).
Iodine unlike many of the other minerals, iodine has only one main function in your horse’s body. It is an important part
of two major hormones that regulate basal metabolism. The margin between safe and toxic dietary levels is small, so it
is best to determine if your horse is already receiving enough iodine from the diet before supplementing.
Selenium is a trace mineral that helps to protect body tissues from free radical damage that occurs during oxidation (the
conversion of feedstuffs into energy). In particular, they act as a defense mechanism against damage to cell membranes
and enzymes. Therefore, most horses will need supplementation to meet the NRC requirement of 1 mg/day for maintenance.
For optimum immune function and exercise recovery, 2 to 3 mg/day is recommended, which is still well below 50
mg/day which may be the upper safe limit.
Cobalt is a micromineral used by intestinal microorganisms to produce vitamin B12, which works with iron and copper to
form healthy red blood cells.
Vitamin A is well-known for its role in maintaining healthy vision, especially night vision. However, it is also needed for
reproduction, immunity, and normal skeletal development in young growing horses and exercising horses that are remodeling
Vitamin D plays an indirect role in bone growth and maintenance by managing the levels of calcium (Ca) in the body.
Horses kept indoors for prolonged periods, horses fed poor quality hay, very young foals or exercising horses that are remodeling
bone may need supplementation.
Vitamin E is considered the most important antioxidant and works closely with selenium to protect the body from the oxidative
stress of exercise, illness and certain medical conditions. Horses are not very efficient in storing vitamin E and
deficiency may be accelerated if the diet is deficient in selenium.
Probiotics are live microorganisms fed to promote healthy digestive and immune function. When these “good” bugs
break down food ingredients that the body normally can’t, they produce energy and vitamins for the body, food for cells in
the cecum and colon, and byproducts that keep the “bad” bugs from growing. Research suggests probiotics are useful in
repopulating the intestine with “good” bugs after antibiotic use and may benefit certain horses with diarrhea. A common
term used for probiotics is direct fed microbials (DFM).
