Why Choose Micro-Phase?
Everyone has one: a horse or pony that seems to live on air alone; one that eats mostly hay (and not very good hay at that), is restricted from grazing, and gets little to no grain. Micro-Phase offers the perfect solution by providing the vitamins and trace minerals necessary to support good health in a tasty, low-calorie pellet.
Micro-Phase is also excellent for horses that need extra nutrition on top of their regular concentrate meal, like lactating mares, hard-working performance horses, and seniors.
When might horses and ponies need additional vitamin and trace mineral supplementation?
When mostly hay is fed
Diets composed entirely of forage are often the healthiest for the horse’s digestive tract. However, forages, particularly dried forms such as hay and hay cubes, do not contain all of the vitamins and trace minerals necessary for optimal health. In fact, levels of vitamins and minerals in forage decrease significantly during harvesting and storage. Micro-Phase contains a complete complement of essential vitamins and minerals.
When unfortified grains are fed
Unfortified grains like oats, fed as the main grain meal, will not provide adequate vitamins and trace minerals. Micro-Phase’s blend of ingredients can be used to effectively balance a diet consisting of plain grains.
When you can’t feed the recommended amount of grain because of calorie or starch and sugar restrictions
Horses and ponies on low-grain diets may not eat enough of a fortified feed to fulfill their vitamin and mineral needs. Most commercial feeds are formulated to be fed at a rate of 4 to 5 pounds per day. If you can’t feed that amount you are cheating your horse or pony out of some of the nutrients they need to remain healthy. Adding Micro-Phase to the diet ensures that you are providing the correct amounts of vitamins and trace minerals to support his/her needs. All this, without adding unwanted calories to the diet.
When natural vitamin E is not readily available in the diet
Grass is your horse’s best source of vitamin E. The vitamin E content of dried forages such as hay and hay cubes is severely diminished, with such forages losing more than 75% of their vitamin content upon harvesting and storage. Therefore, vitamin E supplementation is most critical for horses that are restricted from grazing and are fed diets composed largely of preserved forages. Current research shows that the natural vitamin E found in Micro-Phase is two to three times more potent than the synthetic E found in other feeds and supplements.
Micro-Phase is recommended for:
- Easy keepers eating little to no fortified feed
- Easy keepers on restricted grazing routines
- Horses and ponies in light work consuming all-forage diets
- Horses and ponies fed plain grains or unfortified feeds
- Horses and ponies on restricted diets due to obesity issues
- Senior horses or ponies that need a little extra nourishment
- Horses and ponies of any age or stage that would benefit from additional vitamins and trace minerals, including broodmares in late gestation or nursing, yearlings, hard-working performance horses, or horses with special needs
Which horses will benefit from additional vitamins and why?
Horses that are training and competing vigorously
Hard-working horses require higher levels of many vitamins, especially those vitamins that serve as antioxidants (E, C, and beta carotene, a source of vitamin A). Antioxidants counter the effects of oxidative stress caused by heavy work. For many of these horses, pasture time is limited due to heavy competition schedules and other management concerns, decreasing access to natural vitamins.
Horses with limited access to fresh green grass and/or those eating poor-quality hay
Vitamins quickly lose potency once grass is cut and cured for hay, and they tend to continue to degrade over time when stored. For example, there is a 9.5% loss of vitamin A activity in hay every month. The level of vitamin E in hay drops 70% within the first week of being cut. Horses maintained on hay or processed fiber sources are prime targets for deficiencies.
Horses in high-stress situations, such as frequent travel and relocation
Additional vitamins are needed to support a vigorous immune system and counter the effects of digestive tract stress that accompanies traveling. New environmental conditions, changes in diet, and off-schedule feedings often disturb the delicate balance in the hindgut and inhibit the synthesis of necessary vitamins.
Yearlings and two-year-olds
Vitamins play an important role in the rapid bone and muscular growth seen in young horses. They also support the immune system and play an integral role in the proper energy metabolism that fuels growth. Young, growing horses may require higher levels of vitamins than mature horses.
Last trimester pregnant or lactating mares and breeding stallions
Mares in late pregnancy and lactation are literally eating for two. Nature will deplete a mare’s resources to meet the needs of her fetus or foal, so adequate supplementation is necessary to protect both the mare and her foal. Stallions on a demanding breeding schedule will need additional vitamins to support adequate energy and fertility levels.
Horses recovering from an illness, surgery or traumatic injury
Additional vitamins are needed to support healing of tissue and bones. Possible digestive tract disruptions can reduce the amount of vitamins synthesized by good bugs (microbial population) in the hindgut.
Horses receiving long-term antibiotic therapy
Antibiotics can disrupt the population of good bugs in the hindgut, which synthesize vitamin K and the B vitamins. These vitamins may need to be replaced until the microbial population can recover.
When deciding if vitamin supplementation is right for your horse, take the time to carefully review his or her diet and lifestyle. Modern management practices often lead to the need for supplementation. Discuss your horse’s situation with your veterinarian or equine nutritionist to avoid unnecessary supplementation.

The fat-soluble vitamins
A, D, E and K are known as the fat-soluble vitamins. These vitamins are absorbed in the small intestine and stored in the body, in either the liver or in fatty tissue. Horses, with the help of sunlight, can synthesize vitamin D. Green grass is an excellent natural source of vitamin E and beta carotene, which is metabolized into vitamin A. The vitamins found in fresh, green forages lose their potency when the forages are processed into hay, cubes or pellets, so horses eating little green grass may need supplementation. The good bugs in the hindgut typically synthesize enough vitamin K to meet a horse’s needs.
The water-soluble vitamins
The B-complex vitamins and vitamin C are considered water-soluble vitamins; they are not stored in the horse’s body. The B-complex vitamins are thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin (B12). All B-complex vitamins are available in fresh plant material, such as pasture, but as with fat-soluble vitamins, potency diminishes over time when fresh forage is stored as hay. The horse, with help from the good bugs in the hindgut, can synthesize a certain amount of B vitamins, but those with limited access to fresh pasture, or horses that are working hard or stressed, may need additional supplementation. In a healthy, unstressed horse, adequate amounts of vitamin C can be synthesized from glucose in a horse’s liver.
Minerals are inorganic compounds that serve both as components in body tissue and as catalysts for various body processes. Calcium and phosphorus are perhaps the most recognizable macrominerals. As with all minerals, they are vital to your horse’s well-being.
Calcium makes up 35% of your horse’s bone structure. It supports proper muscle contractions and plays a role in blood clotting.
Phosphorus makes up 14% to 17% of your horse’s bone structure. It supports energy transfer reactions and plays a role in the synthesis of certain proteins.
Calcium and phosphorus must be provided in the appropriate ratios. Diets with more phosphorus than calcium can result in decreased absorption of calcium, which can cause skeletal malformation. A calcium-to-phosphorus (Ca:P) ratio of between 1.2:1 and 2:1 is ideal. Micro-Phase contains a balanced Ca:P ratio.
Selenium works in concert with vitamin E to defend the body’s cells from damaging oxidative byproducts known as free radicals. Free radicals are released during energy production. Selenium is a component of glutathione peroxidase, a beneficial enzyme that prevents free radicals from forming. Glutathione peroxidase also destroys lipid peroxidases (non-beneficial enzymes), which damage cell membranes. Once damaged, cells no longer function properly, leaving horses susceptible to multiple health problems.
Horses use energy to fuel bodily functions and movement. The greater the demand for energy, the greater the number of free radicals produced. Your horse’s body is equipped to deal with small amounts of these oxidative byproducts, but as the demand for energy increases, so does your horse’s need for additional antioxidants to counter the onslaught of free radicals.
Hard-working horses, breeding stock, horses consuming feedstuffs low in selenium, or horses with certain muscular disorders may require supplemental selenium.
However, too much selenium can cause problems so always know how much selenium your horse is getting in his diet. Do not use multiple selenium-containing supplements without the advice of your veterinarian. Micro-Phase is safe to feed with most commercial feeds that contain selenium when both are fed at recommended levels.
The FDA guidelines for selenium are a good place to start when deciding how much selenium should be in your horse’s diet.
The Food and Drug Administration has set the daily recommended level of selenium for an “average” horse at a total of 3 mg per day. This is a very safe level of selenium consumption and well below the maximum tolerable limits. When determining if your horse’s diet contains adequate selenium, you can use this average as a good reference. Each horse is an individual and has individual needs, so it is best to work with your veterinarian or nutritionist to determine your horse’s exact requirements, which in some cases may be higher than the recommended 3 mg per day.
Copper is necessary for healthy connective tissue, cartilage, and bone. Other important functions of copper include red blood cell formation, hoof wall formation, and hair pigmentation.
Zinc plays a role in healthy hooves and coat, bone development, and reproduction.
