Horse Guard Super Weight Gain stands out for its dense formulation that goes beyond simple fat. It combines full-fat extruded soybeans for a high-calorie punch with a digestive support package of prebiotics and probiotics, plus 1,500 IU of Vitamin E per dose for immune support. This makes it a strong candidate for senior horses, hard keepers, or any horse coming off a period of stress or illness where systemic support is as important as raw calories.

The granular form is easy to mix into feed, and owners of ex-racehorses and older geldings report visible improvements in topline and body condition within weeks. One user noted that a senior horse who struggled to maintain weight through a move responded better to this than to other weight builders. The 10 lb bag provides approximately 20 servings for a 1,000 lb horse, making it a convenient option for a single-horse household.

Veteran users caution that the product can lose effectiveness if the bag is exposed to heat or sunlight for extended periods, so proper storage is important. A small number of picky eaters may not finish their full serving, but the majority of feedback confirms high acceptance once the horse becomes accustomed to the taste. It is a comprehensive, science-backed formula for targeted weight gain.

LIFE DATA LABS Farrier S Formula is a product specifically geared toward hoof health, making it an excellent choice when your fat supplement needs to double as a structural support. It delivers a dense complex of phospholipids, omega fatty acids, vitamins, minerals, and amino acids tailored to support healthy hoof wall structure and growth. It is frequently recommended by farriers for horses with chronic hoof issues like crumbling soles or cracking.

The 2X strength formula means you can feed a smaller volume per day to achieve the desired effect, which is a practical advantage if you have a horse that is a light eater. Users report seeing changes in hoof quality as the hoof grows out, typically within a few months. Even notoriously picky horses seem to accept the pelleted form easily, with many owners noting they can feed it without mixing it into anything else.

One review described how it resolved lameness in a mare caused by a hind hoof abscess and crumbling sole, with the horse becoming sound again after six weeks of consistent use. While the price point is higher, the concentrated formula often justifies the investment for horses with persistent hoof problems. This is a specialty product for when fat supplementation is a means to a specific structural end.

Horse Health Joint Combo Hoof & Coat is a strategic hybrid that combines joint support ingredients with hoof and coat nutrition in a single bucket. The formula includes glucosamine HCl, chondroitin sulfate, and MSM for joint function, along with 16 mg of biotin per 2-ounce serving for hoof strength, plus omega-3 and -6 fatty acids for skin and coat health. This makes it an efficient choice for older horses or performance animals that need multi-system support.

The apple-cinnamon flavored pellets are widely accepted, and owners of senior horses with conditions like Cushing’s report noticeable improvements in hoof growth and reduced abscess frequency. One review from a 26-year-old Paint horse owner noted a dramatic improvement in movement and behavior when the supplement was fed consistently, with a clear regression during a week without it.

It is important to note that while this supplement delivers fatty acids, its fat content is secondary to its joint and biotin focus. It is not a high-calorie weight gain tool but rather a maintenance supplement that supports coat and skin health as part of a broader anti-aging or performance support protocol. This is a great option for consolidating multiple daily supplements into one.

Farnam Horseshoer’s Secret is a classic hoof-focused supplement that also delivers a solid profile of omega-3 and -6 fatty acids for coat health. Each 6-ounce serving provides 15 mg of biotin, along with lysine, methionine, copper, and zinc, which are all essential building blocks for keratin production and hoof wall integrity. It is specifically positioned to address cracking, chipping, and vertical splits.

The alfalfa-based pelleted format is palatable and mixes seamlessly with grain. Long-term users spanning years confirm that consistent, daily feeding leads to measurable improvements in hoof strength, with farriers often noting the difference during routine trims. One owner of horses in the hot Texas climate reported that it helped combat the brittle hooves caused by seasonal fluctuation and humidity.

This product requires daily feeding year-round to maintain results. It is not a quick fix but a maintenance strategy. Reviews indicate that it works well on donkeys and mules as well. Its fatty acid profile is a bonus for coat condition, but the primary mechanism is structural hoof support, making it less suited as a standalone weight gain solution.

SmartEquine CocoSoya Oil is a liquid supplement that provides a unique blend of soybean and coconut oils, delivering a balanced spectrum of omega-3, -6, and -9 fatty acids. This oil is specifically designed to improve coat shine and skin health from the inside out. The addition of vitamin E acts as a preservative and provides an extra antioxidant benefit, which is especially useful for horses in regions where hay is low in vitamin E.

The oil form is extremely versatile — owners report using it to hide medications, and it appears to be universally palatable, with horses licking their buckets clean. One user reported that a 17-hand Warmblood maintained weight and developed a deep, dappled coat shine over a year of consistent use. Even non-equine animals like golden retrievers with itchy skin responded positively when included in their diet.

Because it is a pure oil, it is calorie-dense and can help with weight maintenance, but its primary strength is cosmetic and dermatological. The 1-gallon jug typically lasts about a month at the standard 4 oz per day dose. The liquid form may be less convenient for those who prefer dry supplements, and the jug should be stored properly to prevent rancidity.

Manna Pro Cool Calories 100 is a dry fat supplement that delivers a remarkable 99% fat content, making it one of the most concentrated sources of dietary energy on this list. Because it provides cool energy, meaning it does not cause the metabolic heat or hyperactivity often associated with high-grain diets, it is a favorite for performance horses and hard keepers who need weight without the jitters.

The dry pellet form eliminates the mess and spoilage issues associated with liquid oils. Users of older horses, including one owner of a healthy 36-year-old, report it is reliable for maintaining weight in seniors. The supplement includes fatty acids specifically to support skin and coat condition, and many reviews highlight improved hoof health and a glossy coat as secondary benefits.

While it is excellent for weight gain, some users note that it does not stick well to pellets unless the feed is dampened. This can be a minor inconvenience for horses that eat processed feed. The 8 lb bag provides a solid supply, but the volume relative to the calorie density is high, so storage space is a consideration. It is a straightforward, effective tool for adding fat calories without behavioral impact.

Manna Pro Sho-Glo is a complete vitamin and mineral supplement that includes antioxidants and a small amount of fat to support coat health. It is a foundational supplement rather than a high-fat weight gain product. It works best for horses that are already on a balanced feed program but need an extra boost for coat shine and immune function.

The pellet form is highly palatable, and even picky eaters reportedly accept it easily. Owners of horses that have regained weight and improved hoof thickness after being underweight have noted the product’s affordability. It is often used in conjunction with other supplements like biotin for a more comprehensive approach. The 5 lb bag is a good entry size for trying it out.

Because it is not a high-fat concentrate, it will not provide the rapid weight gain that a product like Cool Calories or Horse Guard Super Weight Gain offers. Its main value is in its trace mineral content and general health support. The shelf life is one year after the date stamp, so check freshness upon arrival. It is a solid, budget-friendly base supplement.
