Weighing 25 pounds, it provides a substantial supply, which is handy for regular use during training or stressful events.

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.

The Vetoquinol Zylkene Equine Behavior Support Powder is designed to help manage stress-related behaviors in horses and ponies.

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.
