10 Best Horse Calming Supplements 2026 in the United States

Perfect Prep EQ Training Day+ Pellets is a horse calming supplement designed in pellet form, making it easy to mix with regular feed. Weighing 25 pounds, it provides a substantial supply, which is handy for regular use during training or stressful events. The pellet form generally helps with palatability, as horses often accept pellets better than powders or liquids.

Products in this category typically include natural calming agents like magnesium or herbal extracts, which help reduce anxiety without impacting performance. Customer reviews are strongly positive (4.7 out of 5 stars), suggesting it is effective and well-tolerated. Safety appears good given the lack of reported side effects, but users should always follow recommended feeding instructions and consult a vet if unsure.

This supplement is well-suited for horse owners seeking a natural, easy-to-feed calming aid for training days or events where a calm horse is crucial.

Perfect Prep EQ™ Gold Complete Calming Pellets are designed to help calm horses while also providing support for soreness and stomach health, making them a good choice for horses that get distracted or tense before performances. The pellets come in a 10-pound bag and are easy to feed with your horse’s regular meals. The active ingredients include magnesium, amino acids, and a proprietary blend of natural extracts, which work together to promote relaxation and reduce discomfort. Effects start quickly, often after the first feeding, and reach their peak after 4 to 6 consecutive feedings.

One scoop equals one dose, and the product is safe for horses of all breeds and ages, with no banned substances included. Some users appreciate that the pellets can be used alone or as part of a larger calming system for even better results. Because the calming effect builds over several feedings, it is important to plan ahead before events. Additionally, the taste may be unusual, so some horses might take time to get used to it.

The product comes with clear usage instructions and a warning to monitor each horse’s response, as effects can be strong. This supplement is suited for owners who want a reliable, multi-benefit calming aid that also addresses pain and digestion, but it requires consistent use and attention to individual horse reactions.

The Vetoquinol Zylkene Equine Behavior Support Powder is designed to help manage stress-related behaviors in horses and ponies. Its main ingredient, Alpha-Casozepine, is non-sedative and non-addictive, promoting relaxation without making the horse drowsy. This can be particularly useful for situational stress like travel, weaning, or training.

The supplement is in powder form, with an apple flavor intended to make it more palatable for horses. It is administered as a top dress to feed, with specific dosage instructions based on the horse’s weight and the stressful event duration. Typically, it's given three days prior to the event and can be continued as needed.

Safety-wise, it appears to be a reliable option since it is non-addictive and has no known sedative effects. However, as with any supplement, it's recommended to follow veterinarian advice, especially for long-term use. This product is best suited for horse owners who need a non-sedative, stress-reducing option that can be easily mixed into their horse's feed.
