Calming Supplements For Horses: Expert Guide To Top Options
Discover top-rated calming supplements to help your horse manage stress and anxiety.

Best Calming Supplements for Horses
Horses are naturally prey animals with an instinctive flight response that can trigger anxiety and nervousness in unfamiliar or stressful situations. Whether your horse is competing at shows, traveling to new venues, or struggling with everyday stressors, calming supplements can provide valuable nutritional support for a healthy nervous system. Understanding the various types of calming supplements available and their key ingredients can help you choose the right option for your equine companion.
Understanding Horse Anxiety and Stress
Horses experience stress and anxiety much like humans do, and their reactions can manifest in various ways. Some horses become spooky and reactive, others lose focus and concentration, while some may display tension in their muscles or develop nervous digestive issues. Recognizing these signs is the first step toward helping your horse manage stress more effectively. Proper nutrition and targeted supplementation can support your horse’s natural ability to maintain calmness and focus during challenging situations.
Types of Calming Supplements for Horses
Calming supplements for horses come in three primary categories, each offering different benefits and approaches to supporting equine nervous system health.
Nutrient-Based Calming Supplements
Nutrient-based calming supplements provide essential vitamins and minerals that support proper nervous system function. These formulas are designed to optimize your horse’s nutrient levels, ensuring their nervous system operates at peak efficiency. Many horses may already consume these nutrients through their regular diet, but often in insufficient quantities. Nutrient-based supplements bring these levels into the optimal range, helping horses that display nervousness, edginess, reactivity, and spookiness. If you compete in rated horse shows, nutrient-based supplements are typically your best option as they generally comply with most competition regulations.
Herbal Calming Supplements
Herbal calming supplements harness the natural soothing properties of botanical ingredients to promote relaxation and reduce anxiety. These formulas often combine traditional herbal remedies that have been used for centuries to support nervous system balance. Herbal supplements offer a more natural approach for horse owners seeking alternatives to purely nutrient-based options.
Supplements for Moody Mares
Some calming supplements are specifically formulated to address hormonal influences on mood and behavior in female horses. These specialized formulas may include ingredients designed to support hormonal balance and emotional stability during different stages of the reproductive cycle.
Key Ingredients in Effective Calming Supplements
Magnesium
Magnesium is one of the most essential minerals for promoting relaxation in horses. This macromineral plays a crucial role in regulating the nervous system and muscle function. The majority of magnesium in the horse’s body is found in bone and muscle tissue, where it participates in enzyme activation and muscle contraction. When horses lack adequate magnesium, they may exhibit increased excitability, anxiety, and reactivity. Studies in humans have demonstrated magnesium’s influence on nerve transmission and its anxiolytic (anti-anxiety) effects, and these benefits translate to equine applications as well.
L-Theanine
Derived from green tea, L-theanine is an amino acid that supports the production of calming neurotransmitters in the brain. This ingredient works by increasing alpha wave activity in the brain, promoting a state of relaxed alertness. L-theanine allows horses to remain calm while maintaining focus and awareness of their surroundings, making it ideal for performance horses and those in training.
L-Tryptophan
An essential amino acid that cannot be synthesized by the horse’s body, L-tryptophan must be supplied through diet or supplementation. This amino acid is crucial for the production of serotonin, often called the “happiness hormone,” which is essential for promoting relaxation and reducing fear, stress, and aggression. Research indicates that L-tryptophan may help encourage calm behavior in horses, though effectiveness can vary from one individual to another.
Thiamin (Vitamin B1)
Considered the single most important vitamin for stress relief, thiamin is included in many equine calming supplements. This B-vitamin plays a vital role in carbohydrate metabolism and nerve transmission, both essential functions for maintaining a calm, balanced nervous system. Anecdotal reports suggest that B-vitamin supplements, particularly thiamine, can have a noticeable calming effect on horses under stress.
Valerian Root
This potent herb helps balance a nervous system struggling with excess anxiety and can also address muscle cramps and spasms associated with tension. Valerian is especially helpful for horses that hold their anxiety in their muscles and become tense. However, it’s important to note that valerian root may be a banned substance in some competitions, so discuss its use with your veterinarian before giving it to a competition horse.
Chamomile
Renowned for its soothing properties, chamomile can help alleviate anxiety in horses. This herb provides specific support for the nervous system and is particularly helpful for horses that process nervousness through their gastrointestinal system, such as those prone to “nervous tummies.”
Inositol
Found in nearly every cell in the body, inositol plays a major role in nerve transmission by participating in the action of serotonin, a neurotransmitter that produces feelings of well-being and contentment. This ingredient may be especially helpful for excessively nervous horses.
Alpha-Casozepine
Among all calming supplement ingredients, alpha-casozepine has the most promising research-backed calming effect. This casein peptide is safe and was found effective in studies involving feral ponies. Ponies given alpha-casozepine were found to be less reactive to stressful situations and had a higher level of comfort while learning new skills more readily compared to control groups.

Choosing the Right Calming Supplement for Your Horse
Selecting the appropriate calming supplement depends on several factors, including your horse’s specific needs, competition regulations, and the form of supplementation that works best for your routine.
Consider Your Horse’s Stress Triggers
Understanding what causes your horse anxiety is essential for choosing the right supplement. Horses stressed by competition may benefit from supplements with ingredients like L-theanine that promote calm focus. Horses prone to tension may benefit from formulas containing valerian root. For horses with nervous digestive issues, chamomile-containing supplements may be particularly helpful.
Competition Regulations
If you compete in rated horse shows, nutrient-based supplements are typically your best option, as they generally comply with competition regulations. Some herbal ingredients, particularly valerian root, may be banned in certain competitions, so always verify your specific association’s rules before supplementing.
Form and Administration
Calming supplements come in various forms including pellets, powders, pastes, and solutions. Consider which form is easiest to administer to your horse and fits best into your daily routine. Pastes offer convenience for occasional use or pre-event supplementation, while pellets and powders are ideal for daily supplementation mixed into grain or feed.
Individual Horse Response
Different horses may respond differently to various ingredients and formulations. L-tryptophan effectiveness, for example, seems to vary from horse to horse. It may take some trial and adjustment to find the supplement that works best for your individual horse’s needs.
