Stabled horses are subjected to a constant respiratory challenge from fungal spores and dust in their immediate environment, which can affect their respiratory health and function. Targeted nutritional support can help support the horse?s natural defence against such challenges, and Airways Xtra Strength Powder contains a powerful blend of natural, plant-derived essential oils, known for their role in maintaining respiratory function. Eucalyptus oil is well known for its ability to help clear the respiratory tract of a build-up of mucus caused by constant exposure to dust and spores. Airways? Xtra Strength Powder should be added to the feed daily for horses stabled for long periods, or those experiencing irritation from dust in bedding and hay.
