Well what can I say I’ve tried several different calmers, some made my mare worse, some made no difference but I can honestly say this does work, got it mixed up once with psyllium and couldn’t understand why my mare was so spicy, it was because I was giving her 6 weeks of psyllium and no calmer 🤦🏼♀️back on the calmer with in a few days back to normal, will never make that mistake again 🤣 can’t rate this calmer enough 5⭐️
