An aluminosilicate whose open tetrahedral framework allows ion exchange and reversible dehydration. Benefits of Zeolite for horses include: Improved nutrient digestion, reduced scours, it reduces cribbing (chewing on wood), it improves bone growth and it improves the color of your horse’s coat.


From calcified seaweed, aids in metabolism and essential to muscles. For strong bones and teeth, and helps with blood clotting. Deficiency signs include fragile bones and poor growth and muscular problems.

Glucosamine HCL

Glucosamine HCL is a marine sourced amino sugar. It is found in the body as one of the building blocks of cartilage necessary for its production and growth.

Hyaluronic Acid

Hyaluronic Acid is a special protein occurring naturally throughout the horse’s body. Its function in the body is, amongst other things, to bind water and lubricate moveable parts of the body such as joints and muscles. Some key features include: lubrication of inflamed joints, increased joint mobility, reduction of joint friction, and alleviation of joint pain during activity.


Leucine is an essential amino acid. This means that it must be obtained through the diet in adequate quantities to meet the body‘s needs. Leucine is a member of the branched chain amino acid family, along with Valine and Isoleucine. The three branched-chain amino acids constitute approximately 70 percent of the amino acids in the body proteins. Leucine is obtained by the hydrolysis of protein by pancreatic enzymes during digestion and necessary for optimal growth in the youngest and for the maintenance of nitrogen balance in adults. Leucine is not only a building block of protein; it is THE key essential amino acid of muscle metabolism.

Boswellia Serrata Extract

Boswellia for horses is a powerful painkiller and anti-inflammatory derived from the gum resin of the Boswellia Serrata tree. Boswellia for horses is often referred to as nature’s ‘Bute’ – a reference to the equine medicine phenylbutazone (‘Bute’). On its own – or in combination with other products – it offers a gentle, natural solution to ease inflammation and pain in hard-working equine joints. Boswellia Serrata is gentle on the gastrointestinal tract and safe for long-term use, and has been shown to be very useful in maintaining normal colonic function.

Green Tea Extract

Green tea has demonstrated ability to lower total cholesterol and raise HDL (good) cholesterol in both animals. Results from one animal study suggest that polyphenols in green tea may block the intestinal absorption of cholesterol and promote its excretion from the body.

Several animal studies have found that green tea polyphenols inhibit the growth of esophageal (throat) cancer cells.

Green tea has been used traditionally to control blood sugar in the body. Animal studies suggest that green tea may help prevent the development of type 1 diabetes and slow the progression once it has developed. Therefore, Green tea may help regulate glucose in the body.

Animal studies have shown that green tea helps protect against the development of liver tumors in mice. Results from several animal and human studies suggest that one of the polyphenols present in green tea, known as catechin, may help treat viral hepatitis (inflammation of the liver from a virus). In these studies, catechin was isolated from green tea and used in very high concentrations.

Studies suggest that green tea extract may boost metabolism and help burn fat.

Cats Claw Extract

A woody South American vine, Uncaria tomentosa or a preparation of its root bark, which has antiviral, immunostimulant, and anti-inflammatory properties. Cat’s claw can affect the immune cells responsible for cellular immunity; promote systemic microbial balance, and support antioxidant activity and circulation.


The cultivation and consumption of the Maca root dates back to more than 3000 years ago. This powerful super nutritious root grows at more than 12,500 feet above sea level on the foot of these ancient and sacred mountains. Maca favors reproduction, improves digestibility of food, efficiency in the utilization of oxygen, and is highly energetic. These characteristics are of vital importance to creatures living in the highlands. In normal atmospheric conditions these properties make maca a powerful anti-stress, energizing, sexual, reproductive and physical invigorator.


Skullcap has been used for more than 200 years as a mild relaxant and as a therapy for anxiety and stress. Native Americans as well as traditional European herbalists historically have used skullcap to relieve anxiety and nervousness. Skullcap derives its name from the cap-like appearance of the outer whorl of its small blue or purple flowers. It is a slender, heavily branched plant that grows to a height of 2 – 4 feet and blooms each July. The parts used for medicinal purposes are the leaves, which are harvested in June from a three to four year old skullcap plant.

Skullcap is one of the most widely used herbs for the nervous system. It is an herb with specific actions on the nervous system. In humans, it is used for PMS, migraines, disturbed sleep, seizures, drug addictions and physical or mental stress. Its properties are said to include sedation, anti-spasmodic, anti-convulsive, and vasodilation (expanding blood vessels).

Turmeric Root

A woodland plant (Hydrastis canadensis) of eastern North America, having small greenish-white flowers and a yellow root used in herbal medicine. A Strong Antioxidant, the active constituent in turmeric is known as Curcumin. It has been shown to have a wide range of therapeutic actions. It protects against free radical damage because it is a strong antioxidant. An antioxidant is a substance (such as vitamin E, vitamin C) thought to protect body cells from the damaging effects of oxidation. It reduces inflammation by lowering histamine levels and possibly by increasing production of natural cortisone by the adrenal glands. Curcumin seems to have a protective effect on liver tissue exposed to toxic compounds like liver-damaging drugs. There are also test-tube studies showing inhibition of metastasis (uncontrolled spread) of melanoma (skin cancer) cells or lymphoma tumor cells. This may be attributed to its antioxidant activity in the body. Animal studies from Rutgers have shown a possible use in prevention of tumor development, as well. Turmeric is now being found in blends that help support joint issues with animals.

Yucca Root

The yucca root has nutritional value and is a source of fiber and vitamins in your diet. The yucca root was first used by Native Americans and may have significant medicinal properties to treat several health ailments. It contains properties that may improve animal functioning.

Yucca schidigera is a medicinal plant native to Mexico. According to folk medicine, yucca extracts have anti-arthritic and anti-inflammatory effects. The plant contains several physiologically active phytochemicals. It is a rich source of steroidal saponins, and is used commercially as a saponin source. Saponins have diverse biological effects, including anti-protozoal activity. It has been postulated that saponins may have anti-arthritic properties by suppressing intestinal protozoa, which may have a role in joint inflammation. Yucca is also a rich source of polyphenolics, including resveratrol and a number of other stilbenes (yuccaols A, B, C, D and E). These phenolics have anti-inflammatory activity. They are inhibitors of the nuclear transcription factor NFkappaB. NFkB stimulates synthesis of inducible nitric oxide synthase (iNOS), which causes formation of the inflammatory agent nitric oxide. Yucca phenolics are also anti-oxidants and free-radical scavengers, which may aid in suppressing reactive oxygen species that stimulate inflammatory responses. Based on these findings, further studies on the anti-arthritic effects of Yucca schidigera are warranted.

Nettle Leaf

Nettle is a rich source of vitamin C as well as a source of iron, calcium and potassium. Nettle may be used as a daily feeding supplement for lactating mares, laminitic ponies, arthritic horses and for cases of anemia and poor condition. Nettle can be used as a tonic or immune booster.

Celery Seed

Widely grown as a vegetable and salad plant, the seeds of this plant are used to treat urinary, rheumatic and arthritic problems. A good cleansing, mildly diuretic herb is useful in ridding the system of an accumulation of waste products. An improvement in circulation of fluids encourages a horse to drink and sweat more easily. Celery has a significant antiseptic action with carminative (warming) effects.

Black Cohosh Root

Black Cohosh preparations are derived from the root and rhizome of a shrub-like plant (Cimicifuga racemosa) also known as black snakeroot. The name black cohosh is derived from the dark color and the rough and gnarly structure of the root. (Cohosh is Algonquin for “rough.”) The plant is native to eastern forests of North America.

This herb is helpful for the relief of menstrual cramps and symptoms of menopause. It is a natural supplier of estrogen with clinical studies showing that extracts of black cohosh not only relieve hot flashes, but also depression and vaginal atrophy as related to women.

Mares will experience similar difficulties as women do.

Ginger Extract

One of the first medicinal agents to be recorded in Chinese history, Ginger effectively removes congestion from the lungs and modulates the immune system.


Alfalfa is both unique and nutritive with 60% of the oil present being the highly desirable Omega 3 fatty acids. Alfalfa provides all the essential minerals, trace elements and vitamins in forms that are readily absorbed in your horse’s digestive system. Alfalfa balances the high calcium content of alfalfa with elevated phosphorus resulting in a metabolically sound horse.

Cane Sugar

Being rich in sucrose content, sugarcane has a very high-energy value compared to cultivated grasses like napier, guinea, etc. Sugar cane helps store food energy.

Rice Flour

Made from brown rice. The husk is removed and the raw rice is ground. Rice flour is a particularly good substitute for wheat flour when allergies prevent its use.

Silicon Dioxide

Used to protect horse bones and connective tissues.
