Super Weight Gain 40 lb, Equine Vitamin Mineral, Probiotic & Weight Gain Supplement
Most important from
470 reviews
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.

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.
