10 Best Weight Gain For Horses 2026 in the United States

The Horse Guard Super Weight Gain supplement is designed to help horses gain weight in a healthy manner. One of its key strengths is its quality protein content, which avoids relying on sugars and starches that can have adverse effects. This is beneficial for ensuring a balanced diet and healthy weight gain. The supplement also includes powerful probiotics and prebiotics, which help improve the horse's gut health and increase nutrient absorption from their feed, making it more effective in promoting weight gain.

Additionally, it meets the horse's vitamin and mineral needs with a comprehensive package, which further supports health and weight increase. The inclusion of full oil soybeans provides 'cool energy' that enhances the horse's appearance and condition without causing them to become overly energetic or 'hot'. This could be particularly useful for maintaining a calm demeanor while still promoting weight gain. The high-quality, pharmaceutical-grade ingredients offer peace of mind regarding the product's safety and efficacy.

However, there are some considerations to keep in mind. The product's form as a powder may require careful mixing with the horse's feed to ensure consistency in intake. Additionally, the feeding directions specify precise measurements based on the horse's current body weight, which might require regular adjustments and monitoring. Another potential downside could be the product's size and weight, as it comes in a 40-pound package that may be cumbersome to handle for some. This supplement seems particularly suited for horse owners looking to support healthy weight gain, improve gut health, and ensure balanced nutrition.

The TRM Curragh Carron Flaxseed Oil Digestive Horse Supplement is designed to promote weight gain and improve coat condition in horses. It is made from a high-quality blend of cold-pressed flaxseed oil and calcium, which offers numerous health benefits. The flaxseed oil is an excellent source of Omega 3 and Omega 6 fatty acids, which support skin and coat health, making your horse's coat shiny and healthy.

Additionally, the calcium hydroxide acts as a mild antacid, soothing and protecting the horse's stomach lining, which can improve their appetite and digestion. This is particularly beneficial for horses with sensitive stomachs or those prone to ulcers. The product is also a good source of calories, contributing to weight gain in an easy and palatable form for horses.

If you are looking for a calorie-dense supplement to help your horse gain weight while improving their coat and digestion, this product could be a valuable addition to their diet.

Farnam Weight Builder Horse Weight Supplement is designed to help horses gain and maintain optimal weight while ensuring a balanced diet. Its high-fat formula, containing 50% fat, significantly increases caloric density, which is essential for weight gain. The supplement is easy to mix with regular grain, making it convenient to use. Additionally, it’s free from added sugars, reducing the risk of digestive issues while still providing digestible calories.

One of its standout features is the inclusion of omega-3 fatty acids from flaxseed meal and rice bran, promoting healthy skin and a glossy coat, which can be a concern for horse owners. The product is also palatable, which means horses are likely to enjoy it, making feeding easier.

It’s important to consider that while the product is suitable for horses of all life stages, individual dietary needs may vary based on activity level and specific health conditions. The recommended serving size is 4 oz daily, with flexibility to adjust based on the horse's needs. Some users may find that managing the correct servings can require attention and effort, especially if feeding multiple horses. Moreover, while a 90-day supply is appealing, the effectiveness of gaining weight can depend on the horse’s existing condition, and results may take time to notice.
