Mad Barn’s Trace Mineral Pak is a balanced trace mineral supplement for horses that contains 100% organic minerals.

Deficiencies in key trace minerals over a long period of time, can result in poor hoof and coat condition, depressed athletic performance and decreased energy levels in your horse.

Supplementing with trace minerals like Copper, Zinc, Manganese and Selenium support optimal health by protecting tissues from oxidative stress, providing the catalysts for muscle and tissue growth and boosting the metabolism.

Make sure that your equine companion is getting the trace minerals they need to thrive with Trace Mineral Pak. The concentrated formula provides trace minerals in a form that are safe, highly bioavailable and backed by research.

Why Go Organic?

Unlike other supplements on the market, Mad Barn’s Trace Mineral Pak contains 100% organic ingredients. In nature, trace minerals are chemically bound to the amino acids.

The trace minerals in Trace Mineral Pak are found in a form that nature intended – attached to amino acids or peptides using Advanced Trace Mineral Technology (ATMT).

Supported by more than 21 years of research, trace minerals that utilize ATMT are better able to meet the increased nutritional needs of the modern horse to support optimal health and maximize athletic and reproductive performance.

Trace Mineral Pak contains high levels of trace minerals commonly deficient in the modern equine diet in an organic format for maximum bioavailability.

In addition to superior bioavailability, trace minerals with ATMT:

  • Don’t interfere with digestive processes.
    • Compared to inorganic trace minerals, digestive enzyme activity is higher when using organic minerals.
  • Avoid interactions with other minerals that inhibit absorption.
    • Supplementing with high levels of copper or zinc won’t reduce the utilization of each other.
  • Are free of contaminants found commonly in inorganic trace minerals, like PCB’s and dioxins.

Why Use Trace Mineral Pak?

Zinc, copper and manganese work individually or synergistically to support growth, reproduction and maintain the structural integrity of tissues.

  • Bioplex™ Zinc
    • Has an integral role in the synthesis of collagen and keratin- tissue proteins that make up hair, hooves and skin.
  • Bioplex™ Manganese
    • Co-factor for enzymes that synthesize cartilage, assists with metabolism of carbohydrates and fat and forms the enzyme superoxide dismutase, an antioxidant.
  • Bioplex™ Copper
    • Integrated in enzymes that crosslink collagen and keratin.


An important antioxidant needed for defense against oxidative tissue damage from reactive oxygen species, selenium can be severely deficient in some regions of North America and is needed in higher amounts for horses undergoing intense exercise or have conditions that depress antioxidant status.

Sel-Plex™ is a selenium-enriched yeast that is the most bioavailable form of Selenium currently on the market, with multiple research studies backing its efficacy.


Maintenance of thyroid hormones is imperative for robust metabolic health. Iodine contributes to the synthesis of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).

You should always consult a qualified nutritionist before altering your feed program. Submit your horse’s diet for analysis online and one of our equine nutritionists will be happy to provide a complementary review.


Calcium | Mad Barn USACalcium is a macromineral with well described roles in bones and teeth development in horses. Calcium and phosphorus are usually discussed together because bones store them in a 2:1 ratio of calcium-to-phosphorus. This ratio should also be attained in the diet.

While most of the calcium found in the horse’s body is in bone tissue, this mineral is also involved in certain enzymatic functions, cell membrane function, muscle contractions and blood coagulation. Calcium ions mobilized from bone are also important for transmitting nerve impulses.

Young horses, growing horses, lactating mares and late-gestation broodmares all have higher calcium requirements than typical adult horses. Severe calcium deficiency in horses causing noticeable symptoms such as “big head” is less common today than in the past. However, deficiency may occur when horses consume certain subtropical grasses that are high in oxalate which restricts calcium absorption.


Cobalt | Mad Barn USACobalt is a micromineral that is required within the horse’s hindgut to synthesize the vitamin cobalamin (Vitamin B12). Microbes present in the hindgut convert cobalt into its active form cyanocobalamin by way of fermentation.

Cyanocobalamin is required for red blood cell formation, protein synthesis, carbohydrate and fat metabolism, reproductive function, cardiovascular health and the methylation of homocysteine to methionine. Racehorses will sometimes supplement with additional sources of Cobalamin for a purported boost in athletic performance.

The essential trace mineral Cobalt is found naturally in horse feeds and there have not been any reported cases of deficiency. Signs of inadequate intake can include loss of appetite, anemia, poor growth, lethargy and other symptoms associated with low vitamin B12 consumption.

Some sources report that supplementation is necessary in regions where the soil does not naturally contain adequate amounts such as Florida, New England, Australia, New Zealand, and Norway. As a supplement, it is commonly provided in the form of Vitamin B12 or cobalt carbonate and it has a Max Tolerable Level of 25 mg/kg total dietary concentration.


Copper | Mad Barn USACopper is a micromineral that is required by the horse for proper nervous system function, antioxidant defense, cardiac function, bone development, cellular respiration, keratinization, tissue pigmentation and the formation of connective tissue. It is a catalytic co-factor for many important enzymes, meaning that it is required for these enzyme’s activity as a catalyst.

If copper levels are not adequate in the horse’s diet, it can lead to pigmentation abnormalities, sensitive skin, sluggishness, bone demineralization, osteoporosis, arthritis, liver problems, digestive problems, anemia, neutropenia, or leukopenia. Deficiency may be common in certain geographic regions where soil content is naturally low in copper.

Absorption of this mineral from the gastrointestinal tract is between 5 to 10% in adults and may be reduced during times of disease or if the horse is consuming a diet high in phytates or competing minerals. To increase levels, a highly bioavailable form of this mineral like Bioplex Copper (copper proteinate) is recommended.


DDGS | Mad Barn USADistiller’s dried grains with solubles (DDGS) refers to the “spent” cereal grains that are produced as a byproduct in the manufacturing of ethanol. The starch in these grains is largely broken down converted into ethanol. These grains are nutrient rich and low in simple sugars, making them ideal as animal feed.

DDGS is commonly used as a protein supplement because it is particularly high in digestible protein. This is a form of protein that does not get broken down as much in the gastrointestinal tract and is better absorbed by the body to meet the horse’s protein needs.

It also contains a rich supply of fatty acids, making it a good energy source for performance horses. According to one analysis, DDGS is three times more concentrated in fat, protein, fibre, phosphorus and sulfur compared to standard grains.


Manganese | Mad Barn USAManganese is a trace mineral that is required by horses to form chondroitin sulfate – a component of cartilage. It is essential for bone development, reproductive function, digestion of fats and carbohydrates, disease resistance and for normal enzyme activity.

It is recommended for horses to consume 40 ppm of this mineral in their diet. Though rare, deficiency can cause serious problems for a horse. Horses that do not get enough Manganese may experience bone abnormalities, lameness, bowed tendons, inhibited growth and impaired fertility.

Manganese is also required to form the natural endogenous antioxidant superoxide dismutase. It has been researched for its potential use as an antioxidant agent in equine animals.


Selenium | Mad Barn USASelenium is a micromineral that is important for immune function, cardiovascular health, thyroid function and muscle development. Horses also require this mineral to prevent white muscle disease. More recently, its been shown to be a key component of antioxidants that are present in all cells of the body and help protect from oxidative stress.

Selenium is a unique mineral as it is a part of two amino acids, seleno-methionine and seleno-cysteine that are precisely incorporated into antioxidant proteins. These seleno-amino acids are stored in the liver and transported to other cells as needed. Selenium is required to synthesize 30-35 different selenoproteins with a wide range of functions in cellular reactions.

Concentrations of this mineral in the soil vary significantly throughout different regions of the world. Selenium supplementation of your horse’s diet is particularly important in areas where the soil Se content is low, including most coastal areas of North America.


Zinc | Mad Barn USAZinc is an essential trace mineral that is required by horses for the immune system, tissue repair, growth, fertility and fetal development. It is involved in over 100 different enzymatic reactions in the body that affect hormone metabolism, energy synthesis, protein synthesis, collagen and keratin formation, blood clotting, insulin production and more.

Zinc is found most abundantly in the eyes and prostate gland followed by bone, skin and muscle tissue. Low levels of zinc in the diet can contribute to subnormal growth, fatigue, problems with hair, hoof and skin quality, impaired wound healing, loss of appetite, anemia and high frequency of colds and other diseases.

According to the NRC’s Nutrient Requirements of Horses, a 500 kg (1,100-pound) mature horse requires 400 mg per day of Zinc. Requirements are higher for horses that are lactating or undergoing heavy work. Many horses do not obtain optimal amounts of this mineral from their forage and could benefit from supplementation.

Zinc is commonly supplemented in balance with Copper because the two minerals compete for the same absorption pathway in the gastrointestinal tract.

    A Thanks for your question! Generally, the average hay tends to have relatively lower levels of copper compared to its levels of zinc. The final ratio of zinc and copper in the total diet is dependent on both the hay and the supplements provided. However, each hay is unique! Depending on your needs, we also have 3:1 Zinc:Copper available or individual levels zinc and copper supplements to help balance the diet.

    A Trace Mineral Pak does not contain any added iron. The iron in the product, as shown on the guaranteed analysis (480 mg/kg), comes from the iron that naturally exists in the other ingredients. Giving the recommended dose for a 500 kg horse of 10 grams would only supply 4.8 mg of iron. To put this in perspective, the average mixed grass hay will supply roughly 150 mg of iron per kg. If you were feeding around 10 kg of this hay, it would contribute 1,500 mg of iron to the diet.
