The first combination of Garlic and Vitamin C for animals, plus Chinese Herbs, Astragulus and Schisandra and a touch of Zinc - all in one blend! Odor-modified garlic minimizes unpleasant odors and is great for fussy eaters. Its anti-fungal, antiviral and antioxidant properties help support the immune system and upper respiratory tract. Use throughout the entire year, during the summer to help keep insects away, and for immune and respiratory support. Use before shipping long distances, when treating skin fungus, or for upper respiratory conditions. An average-size horse uses 1/2 oz. per day.
