10 Best Horse Calming Supplements 2025 in the United States

Formula 707 Calming Equine Supplement is designed to help nervous and excitable horses relax and focus better during training or work. It contains key calming ingredients like L-Tryptophan, which supports serotonin production to reduce anxiety; Thiamine (Vitamin B1), which helps with important nutritional and metabolic functions; and Magnesium, known for promoting muscle relaxation. This mix targets the horse’s nervous system balance in three ways: mood support, proper nutrition, and physical calmness.

The supplement comes in a large 20-pound bag, providing about 160 servings, making it a cost-effective option for regular use. While the exact dosage and duration of effect can vary depending on your horse, regular use as directed helps maintain a steady calming influence. Horses generally accept the supplement well, indicating good palatability, which is important for consistent feeding. Made by a trusted company with a long history in equine care, it’s a reliable choice for owners looking to ease anxiety without harsh chemicals.

However, as with any supplement, it’s important to follow dosage instructions closely and monitor your horse for any unexpected reactions. Some horses may respond differently, so consulting your vet before starting is recommended. This product suits horse owners looking for natural, nutritional support to soothe anxious horses and improve focus without sedation.

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.

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.

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.
