Purina Enrich Plus is the gold standard for metabolic horses. This concentrated pelleted balancer is designed to be fed with hay or pasture — it delivers vitamins, minerals, and protein without the starch load of traditional grain. The low sugar and starch content (under 10%) makes it a safe foundation for horses with insulin resistance or a history of laminitis.

What sets this formula apart is the inclusion of vegetable oils for a glossy coat, plus antioxidant support from selenium and vitamin E. The B vitamin complex supports metabolic function, which is critical for horses struggling to process energy efficiently. Owners frequently report improved topline and steady energy levels after switching from grain-based feeds.

In my own feeding program, Enrich Plus is the backbone. It’s cost-effective because you feed much less volume, and the 55-pound bag lasts a long time. Just be sure to introduce it gradually over a week to let the gut microbiome adjust.

HEIRO Insulin Rescue takes a different approach — a proprietary blend of herbs including fenugreek, cinnamon, and milk thistle, combined with magnesium and vitamin E. It’s a powdered supplement meant to be added to the horse’s daily ration. Many owners of insulin-resistant horses turn to this when they want a more natural support alongside a low-NSC diet.

The formulation is veterinarian-developed and completely free of fillers, artificial colors, and preservatives. Fenugreek and cinnamon have been studied for their potential to support glucose metabolism, while magnesium helps calm nervous tension often seen in metabolic horses. The ocean kelp provides trace minerals that may support thyroid function.

I’ve seen this work best as a complementary product for horses that still show metabolic symptoms despite a clean diet. It’s not a replacement for a proper ration balancer, but it can be the missing piece for a horse that needs extra metabolic support. The 30-serving container makes it easy to trial for a month.

Metabolic horses are often older and carrying joint stress, especially if they’ve had laminitic episodes that alter their gait. Formula 707 Joint 6in1 combines glucosamine, chondroitin, MSM, green-lipped mussel, collagen, and bromelain in an alfalfa-based pellet. That’s six separate joint supports in one scoop.

What impresses me is the palatability — Formula 707 has been around since 1946 and they know how to make horses eat it. The alfalfa base actually complements a forage diet rather than adding unnecessary grain. Bromelain provides natural anti-inflammatory support, which can benefit horses with chronic low-grade inflammation often seen in metabolic syndrome.

This is a targeted supplement, not a ration balancer. I recommend it for metabolic horses that also show stiffness, reduced range of motion, or previous joint injuries. Use it alongside a low-NSC balancer like Purina Enrich Plus for a comprehensive program.

Putting weight on a metabolic horse is a delicate balancing act — you need calories without sugar. Farnam Weight Builder answers with a powdered formula that’s 50% fat, derived from flaxseed meal and rice bran. That means dense, easily digestible calories that won’t spike insulin.

The inclusion of omega-3 fatty acids is a nice bonus for skin and coat health, often a concern in horses with metabolic issues. I’ve used this for rescue horses that were underweight and insulin-resistant, and it helped them fill out without triggering laminitic episodes. The powder mixes easily into a wet ration or a small amount of the balancer.

At 7.5 pounds, it provides a 30-day supply at the standard 4-ounce serving. It’s a smart choice for hard keepers that need extra caloric density but can’t tolerate grain or molasses-based weight builders.

Horse Guard Super Weight Gain takes a three-pronged approach: full-fat extruded soybeans for protein and fat, a probiotic/prebiotic blend for gut health, and a vitamin-mineral package that includes 1,500 IU of vitamin E per serving. It’s designed specifically for hard keepers, including seniors and rescued horses with metabolic sensitivity.

The extruded soy provides highly digestible protein that supports topline and muscle condition without the risk of colic from raw soy. Probiotics help stabilize the gut flora, which is often compromised in horses on restricted forage diets. Each 10-pound bag gives about 20 servings for a 1,000-pound horse, making it one of the more affordable concentrated supplements.

I recommend this for owners on a budget who still want a quality ingredient profile. It’s not a complete balancer, but combined with a low-starch hay and a ration balancer, it can turn around a horse that’s been fighting to hold weight.

Metabolic horses often live on sandy soils or overgrazed pastures where sand accumulation is a real threat. Farnam Equi Aid provides natural psyllium husk fiber that helps sweep sand from the ventral colon. The apple and molasses flavor makes it highly palatable, though the molasses content should be considered for horses with severe insulin resistance (a small amount is usually acceptable given the small serving).

The pelletted form is much less messy than psyllium powder. It’s NASC certified and veterinarian recommended. Many owners use it monthly as a maintenance protocol, and I’ve seen it prevent sand colic episodes in horses that graze on sandy ground.

This is not a ration balancer — it’s a digestive supplement. But for metabolic horses on pasture, a clean digestive tract is essential for nutrient absorption. Combine it with your daily ration balancer for a complete gut health program.

Hoof quality is a major concern for metabolic horses — laminitic episodes leave hooves weak, cracked, and slow to grow. Formula 707 Hoof Health delivers a potent dose of D-biotin, DL-methionine, L-lysine, and calcium in a palatable pellet. The combination supports keratin production and hoof wall integrity.

This formula is veterinarian-formulated and recommended by farriers, which carries weight. It contains more ingredients than many competitors, and the inclusion of methionine improves the bioavailability of biotin. Owners report visible improvements in hoof growth and texture within a few months of consistent use.

I use this as a staple for any horse with a history of laminitis. Combined with a low-sugar diet, it helps rebuild hooves from the inside out. The 5-pound bag provides 80 servings, making it a cost-effective long-term investment.

Manna Pro Cool Calories 100 is a dry fat supplement that packs over two and a half times the energy of carbohydrates per pound. It’s 99% fat, providing cool, focused energy without the heat or fizziness of high-grain diets. For metabolic horses that need to gain or maintain weight without sugar, this is a clean option.

The fat source is stabilized rice bran, which is high in fatty acids for skin and coat condition. It’s highly palatable and can be sprinkled directly over the ration balancer. I’ve used it for sport horses with metabolic concerns and for seniors that have trouble holding condition. The 8-pound bag lasts a while because you feed only a few ounces per day.

This is not a nutrient balancer — it’s strictly a calorie booster. But for horses that are doing well on a low-NSC diet but still need more energy, Cool Calories is a safe, effective add-on.

RICHDEL Legacy Pellets are formulated specifically for horses 15 years and older, a demographic that overlaps heavily with metabolic syndrome. This supplement combines glucosamine, chondroitin sulfate, MSM, yucca, vitamin C, and vitamin E in a vegetable-flavored pellet. The addition of yucca provides natural anti-inflammatory support for aging joints.

What I appreciate is the targeted senior formulation — older horses often need both joint and immune support. Vitamin E supports nerve and muscle function, while MSM and glucosamine work on connective tissue. The 5-pound bag is manageable for a single horse trial.

This product works best as a targeted joint supplement, not a complete diet. For metabolic seniors, I pair it with Purina Enrich Plus and a fat source like Cool Calories. Owners often report better mobility and fewer signs of stiffness within a few weeks.

Metabolic horses are often prone to dehydration, especially in hot weather or after exercise, and they may refuse plain water. Gallagher’s Water is a powdered electrolyte mix with trace minerals and natural flavors — no sugar, no artificial sweeteners, no caffeine. It’s designed to encourage horses to drink more, which is critical for kidney and digestive health.

The formulation is FEI compliant and free of banned substances, making it safe for competition horses. It contains alfalfa, which adds a palatable natural flavor. I’ve used it for horses that boarded at shows and refused to drink, and it worked within minutes to get them hydrating.

While not a ration balancer, hydration is a foundational part of any metabolic horse care plan. Poor hydration increases the risk of impaction colic and exacerbates electrolyte imbalances. This is a smart tool to have on hand, especially for picky drinkers.

Vitamin E is a critical antioxidant for metabolic horses, especially those with limited pasture access. Health-E delivers over 14,000 IU of dl-alpha tocopherol per ounce in a fine powder that mixes easily into grain. It’s low in sugar, starch, and fructans — ideal for insulin-sensitive horses.

This formula comes from equine veterinarian Dr. Frank Reilly, DVM, and is university-tested for consistency. Vitamin E supports immune function, muscle integrity, nerve health, and skin condition. In horses with metabolic syndrome, oxidative stress is elevated, making this supplement more than just a nice-to-have.

The 3.2-pound container provides 180 servings at a standard dose. It’s one of the most concentrated and budget-friendly vitamin E options on the market. I recommend it as a daily add-on for any metabolic horse that is not on full pasture turnout.
