Buying Guide

Match supplement to the horse's goal

Choose a formula focused on caloric density for weight gain or one with targeted amino acids and creatine for muscle development depending on whether you need general weight or conditioned muscle mass

Check macronutrient profile

Look for high-fat and quality protein sources on labels—fat increases calories per scoop while digestible protein and lysine support tissue repair and growth

Consider delivery form and palatability

Crumble, powder, and liquid formulations affect mixing ease and acceptance—select a form your horse readily eats and that integrates with its current feed routine

Review additional functional ingredients

Ingredients like creatine, lysine, and hoof-support nutrients can address muscle metabolism and overall condition, adding value beyond simple calories

Compare unit sizes for value

Assess cost per serving across available sizes to determine long-term affordability, especially for ongoing maintenance versus short-term rehabilitation
