Blue Chip Calming combines all the high-quality ingredients of Blue Chip feed balancers, PLUS magnesium, L-tryptophan and chamomile which have proven calming effects on ponies and horses. The primary reason for combining a calmer and a feed balancer is that stress and digestion have a symbiotic relationship; stress can cause digestive issues, and digestive issues can cause stress. The probiotics in Calming balancer restore the natural balance of the gut flora and help to maintain the natural well-being of the digestive system, allowing optimum utilisation of the carefully formulated combination of vitamins, minerals and nutrients present in all the Blue Chip balancers.
