Via Calm is an all-natural powdered supplement designed for horses that show nervousness, restlessness or excitability in response to stress. Each dose supplies l-tryptophan, thiamine, calcium and magnesium alongside Yea-Sacc 1026, a live yeast culture ingredient included to support digestion and gut stability. The powder is mixed directly into a horse's regular feed ration and is intended for daily use or as a pre-event addition ahead of travel, training or competition. A measuring scoop is included in the tub for consistent serving sizes. The formula is manufactured in the United States and is intended for equine use only. Horse owners competing under drug-testing rules should review sanctioning body policies, since the tryptophan content may carry withdrawal requirements.
