The first combination of Garlic and Vitamin C for animals, plus Chinese Herbs, Astragulus and Schisandra with a touch of Zinc - all in one blend! Cold processed, odor-modified garlic minimizes unpleasant odors and is great for fussy eaters. It helps support the immune system and upper respiratory tract. Use throughout the entire year, especially 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.
