Alpha-Lipoic Acid (ALA)
Alpha-lipoic acid (ALA) is a naturally occurring antioxidant and coenzyme involved in mitochondrial energy metabolism. It functions as both a water- and fat-soluble antioxidant, allowing it to act throughout the cell to neutralize free radicals and regenerate other antioxidants such as Vitamins C and E and Coenzyme Q10.
ALA supports glucose metabolism and helps maintain normal insulin function by influencing cellular glucose uptake and mitochondrial energy efficiency. These properties make it useful in supporting healthy metabolic function in horses, particularly those requiring nutritional support for maintaining normal blood sugar regulation or recovering from exercise-induced oxidative stress.
In equine studies, alpha-lipoic acid supplementation has been shown to support antioxidant capacity, enhance insulin sensitivity, and promote balanced inflammatory responses during training. Its unique dual solubility and redox activity make it an important nutrient for maintaining cellular health and metabolic balance.
Chromium is an essential trace mineral that supports normal carbohydrate, lipid, and protein metabolism. It contributes to healthy glucose utilization and insulin function, which are critical for maintaining metabolic balance and energy regulation in horses.
Chromium yeast is an organic, highly bioavailable form of chromium in which the mineral is incorporated into yeast biomass (Saccharomyces cerevisiae). This form enhances intestinal absorption and cellular uptake compared to inorganic sources. By supporting efficient glucose transport into cells, chromium yeast helps maintain normal insulin sensitivity and energy metabolism in both performance and metabolically challenged horses.
In horses under heavy training or metabolic stress, chromium supplementation has been shown to help sustain normal post-exercise glucose and insulin responses, supporting recovery and endurance. Chromium yeast provides a safe, physiologically relevant source of this micronutrient, ensuring consistent delivery and utilization.
Citric acid is a naturally occurring compound found in citrus fruits such as lemons and oranges. In equine supplements, it is commonly used as a preservative and natural flavouring agent.
Citric acid helps protect sensitive ingredients—including vitamins, minerals, and probiotics—by improving their stability during storage. This preservation function supports consistent nutrient quality throughout the product’s shelf life.
In the digestive tract, citric acid can enhance the solubility of certain minerals, supporting efficient absorption of nutrients such as calcium and potassium. It may also contribute antioxidant support; research in animals and humans indicates that citric acid can help limit oxidative reactions in cells and support normal redox balance.
Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant found in the cell mitochondria, where it plays an essential role in cellular energy metabolism. It supports adenosine triphosphate (ATP) synthesis and helps maintain normal oxidative balance by scavenging free radicals and regenerating other antioxidants such as Vitamin E.
In horses, CoQ10 supplementation helps support efficient energy utilization, aerobic performance, and recovery from exercise by promoting mitochondrial function. Its antioxidant activity contributes to muscle health and helps protect cells from oxidative stress associated with physical exertion and metabolic activity. Research in horses demonstrates that CoQ10 supplementation can increase plasma and muscle CoQ10 concentrations, supporting normal energy metabolism and redox balance.
Docosahexaenoic acid (DHA) is a long-chain omega-3 fatty acid that supports inflammatory balance, joint mobility, cardiovascular health, and immune resilience. It is a structural component of cell membranes and contributes to normal signaling in tissues such as the brain, retina, and muscle.
In the horse, DHA and eicosapentaenoic acid (EPA) are the primary omega-3 fatty acids that generate bioactive compounds—resolvins and protectins—which help regulate inflammation and oxidative stress. Because the conversion of alpha-linolenic acid (ALA) from plant sources to DHA and EPA is inefficient, direct supplementation with marine-derived DHA (such as from microalgae or fish oil) provides a more effective source of these functional lipids than supplementing with ALA alone. .
DHA supplementation has been shown in equine research to support metabolic health, respiratory function, and post-exercise recovery, particularly in horses with higher oxidative or inflammatory demands. In horses, dietary supplementation with DHA has been shown to improve insulin sensitivity and support healthier insulin levels. This fatty acid also benefits digestive health by modulating inflammation in the gut and supporting a healthy gastrointestinal lining. It can also help promote a balanced microbiome. Microalgal DHA offers a sustainable, contaminant-free source suitable for performance and metabolic support.
Magnesium is an essential macro-mineral involved in hundreds of enzymatic reactions that regulate energy metabolism, nerve transmission, and muscle contraction. It supports bone integrity, cardiovascular function, and normal insulin sensitivity in horses.
In muscle tissue, magnesium contributes to relaxation following contraction, helping to maintain normal muscle tone and reducing the risk of cramping or tightness. It also plays a role in maintaining a calm temperament by supporting balanced nervous system activity, particularly in horses prone to stress or excitability.
Magnesium oxide is a highly concentrated inorganic source of magnesium commonly used in equine diets. It provides a bioavailable and cost-effective way to maintain optimal magnesium levels, especially for horses with limited access to fresh forage or those losing electrolytes through heavy sweating or training.
Turmeric (Curcuma longa) is a rhizomatous plant in the ginger family that naturally contains curcuminoids such as curcumin. These compounds help maintain normal oxidative balance and support the body’s natural inflammatory response. Turmeric has a long history of use in traditional systems of medicine and is now widely incorporated into equine nutrition for its functional properties.
In horses, turmeric contributes to joint health, mobility, and overall metabolic balance. Curcumin supports antioxidant defenses that help protect cells from free radical damage and may assist in maintaining healthy glucose metabolism and insulin function. Research in multiple species demonstrates mechanisms consistent with these benefits, while equine-specific in-vitro studies indicate similar potential biological activity. Further studies are needed to establish effective levels and physiological responses in horses.
May support normal glucose metabolism and normal insulin production. Supports healthy weight management.

Frequently Asked Questions
MagneChrome+ is a pelleted supplement formulated to support normal glucose metabolism and insulin sensitivity in horses. It combines key nutrients including magnesium, chromium yeast, turmeric, and CoQ10 to help maintain balanced energy utilization and healthy metabolic function. This formula is especially suited for horses with insulin resistance (IR), PPID (Cushing’s), equine metabolic syndrome (EMS), or those at risk of laminitis. MagneChrome+ supports blood sugar regulation and metabolic balance as part of a comprehensive low-NSC diet and management program.
MagneChrome+ is formulated to provide nutritional support for horses with metabolic concerns such as insulin resistance (IR), equine metabolic syndrome (EMS), PPID (Cushing’s), or a history of laminitis. It can also benefit easy keepers, overweight horses, and those with uneven fat deposits or a cresty neck. MagneChrome+ provides magnesium and chromium to support normal glucose metabolism and insulin sensitivity, while turmeric and CoQ10 supply natural antioxidant compounds that help manage oxidative stress and support normal regulation of inflammation. It should be fed alongside a complete vitamin and mineral supplement such as Omneity and used as part of a low-NSC feeding program under veterinary or nutritionist guidance.
MagneChrome+ provides nutrients that help maintain normal insulin function and glucose utilization. Magnesium and chromium work together to support insulin sensitivity and proper carbohydrate metabolism, while turmeric and CoQ10 act as antioxidants that promote healthy muscle and vascular tissue function. By supporting cellular energy balance and nutrient efficiency, MagneChrome+ helps horses maintain healthier body condition and metabolic function when used alongside appropriate diet and exercise management.
A cresty neck is often a visible sign of regional fat accumulation and reduced insulin sensitivity. MagneChrome+ provides magnesium and chromium, two nutrients that support normal glucose uptake and help maintain balanced insulin activity. By promoting healthier carbohydrate metabolism and improving nutrient utilization, MagneChrome+ can assist in managing the underlying metabolic imbalance that contributes to fat deposits along the crest when used alongside proper diet, exercise, and veterinary monitoring.
Yes. Horses that have previously experienced laminitis often have underlying insulin resistance or metabolic challenges that affect normal circulation and inflammatory balance. MagneChrome+ provides nutrients that support healthy insulin regulation, oxidative balance, and homeostatic control of inflammation. Its antioxidant ingredients, including turmeric and CoQ10, help maintain normal vascular function and tissue integrity, supporting overall hoof health. MagneChrome+ should be fed as part of a balanced, low-NSC diet and ongoing veterinary management plan for horses prone to laminitis.
Results vary depending on the horse’s condition, diet, and management. Some horses show improvements in comfort, attitude, or energy within 4 weeks, while visible changes in body composition and topline may take 8-12 weeks of consistent feeding. Long-term use alongside a balanced, low-NSC diet helps support ongoing metabolic balance and normal glucose regulation over time.
MagneChrome+ does not provide a full vitamin and mineral profile and should not be used as a standalone balancer. It is designed to be used with a vitamin and mineral supplement such as Mad Barn’s Omneity. When paired with Omneity, MagneChrome+ provides targeted metabolic support in addition to the full spectrum of vitamins, minerals, and amino acids required for daily maintenance.
MagneChrome+ is designed to complement Omneity, which provides a comprehensive base of vitamins, minerals, and amino acids to meet daily nutrient requirements. While MagneChrome+ delivers targeted support for glucose metabolism and insulin regulation, it does not supply the full spectrum of essential nutrients required in the diet. Feeding it with Omneity ensures your horse receives complete, balanced nutrition while getting the added metabolic and antioxidant support MagneChrome+ provides. This pairing is ideal for horses with insulin resistance, PPID, or EMS that need enhanced support beyond a standard ration balancer.
AminoTrace+ and MagneChrome+ both support horses with metabolic issues, but they are formulated for different purposes. AminoTrace+ is a complete vitamin and mineral supplement that includes elevated levels of magnesium, chromium, and other nutrients to support insulin sensitivity and overall metabolic health. It provides everything your horse needs in one balanced product.
MagneChrome+, on the other hand, is designed to be used with Mad Barn’s Omneity. It provides targeted metabolic support for horses that are already receiving a complete vitamin and mineral program but could benefit from additional magnesium, chromium, and antioxidant nutrients such as turmeric and CoQ10. In short, AminoTrace+ is an all-in-one option, while MagneChrome+ is used to enhance existing feeding programs.
MagneChrome+ should be fed with Omneity for a complete, balanced nutrition program. It should not be used alongside AminoTrace+, as AminoTrace+ already contains elevated levels of magnesium and chromium, which would duplicate the key nutrients in MagneChrome+. Horses currently on AminoTrace+ do not require additional metabolic support from this product.
MagneChrome+ provides more than just magnesium and chromium; it combines these minerals with turmeric, CoQ10, and other antioxidants to offer broader nutritional support for metabolic health. Each 100 g serving provides 10 grams of magnesium and 12 mg of chromium, along with bioactive compounds that support healthy circulation, antioxidant defense, and normal glucose utilization. Feeding MagneChrome+ gives your horse a more comprehensive approach to metabolic support than supplementing magnesium or chromium individually.
MagneChrome+ is formulated as a pelleted supplement to improve palatabilty. The pellets are made with low-NSC oat hulls (the fibrous outer layer of the oat, not the grain itself), which are low in sugar or starch. Most horses accept MagneChrome+ when it is introduced gradually. For selective eaters, it can be mixed with soaked forage pellets or beet pulp. All Mad Barn products come with a 100% Customer Happiness Guarantee — if your horse won’t eat it, we’ll provide a refund or store credit.
MagneChrome+ does not contain unnecessary fillers. A small amount of low-NSC oat hulls is used as a pelleting agent to help bind the ingredients and improve texture. Oat hulls are the fibrous outer casing of the oat seed and contain minimal starch or sugar, making them safe for metabolic horses. The inclusion rate is very low and does not add significant calories, ensuring the product remains suitable for insulin-resistant, PPID, and laminitic horses.
MagneChrome+ has a very low non-structural carbohydrate (NSC) content of 7%. This makes it safe for horses with insulin resistance (IR), equine metabolic syndrome (EMS), PPID (Cushing’s), or laminitis. The small amount of low-NSC oat hulls used as a pelleting agent contributes limited starch or sugar, ensuring the product remains compatible with low-glycemic feeding programs.
MagneChrome+ is intended for horses with metabolic concerns who are already receiving a complete vitamin and mineral supplement such as Omneity. It should not be used in:
Horses receiving other medications, unless directed by a veterinarian
Horses with bleeding disorders
Horses with gastric ulceration
Always consult your veterinarian before adding MagneChrome+ if your horse has pre-existing medical conditions or is on other supplements or prescribed drugs.
If your horse is currently receiving prescription medications, such as pergolide (Prascend®) or other treatments for metabolic or inflammatory conditions, consult your veterinarian before adding MagneChrome+. While this supplement is generally well tolerated, it contains herbal ingredients that may influence nutrient metabolism or interact with certain drugs. Always seek veterinary guidance before combining supplements with medications.
