Stress can hurt your horse’s health, so help keep him calm and comforted during stressful times with the Vetoquinol Zylkene Equine Behavior Support Horse Supplement Powder 2000 mg. The non-drowsy formula uses alpha-casozepine, a natural ingredient found in cow’s milk, to help balance the stress reactions of horses safely and with no tranquilizing or sedating effects. Milk-sourced alpha-casozepine is known to promote relaxation in babies, and it works in a similar way in an adult horse or pony, giving him a sense of comfort and contentment to help him cope with stress or adapt to new situations. It’s perfect to help horses adapt to stressful situations such as new environments, loading and travel, vet visits, and during weaning, stall rest, and social regrouping. It’s also great for stress-related behavior problems and behavior management. Plus, it’s free of lactose and preservatives, making it ideal for sensitives, and contains no prohibited substances.

  • Amazing, love this product!

    By on

    Absolutely love this product. My daughter shows at the 3 ft hunters and we have a very strong willed horse, this product has helped him to stay calm and focused to do his job and for both of them to progress as he does get stressed at horse shows. Would highly recommend it.
