Respirator provides valuable nutritional support to the respiratory mucosal immune system and the delicate capillary blood vessels that surround the lungs. Research shows that by supplementing the diet with naturally sourced anti-oxidants, the horses lungs can be given valuable support. Respirator contains a concentrated solution of natural anti-oxidants, alongside herbs such as ginger, rosehip and blueberries, chosen for their targeted support of healthy lung function. Echinacea is also included for immune system support. Respirator is also recommended where close contact with other horses showing respiratory stress may be cause for concern. Essential oils in Respirator Boost help maintain clear airways.
