Mega Dose features the complete  vitamin-mineral-probiotic package of Horse Guard and the complete hoof supplement of Hoof Guard into one easy 4 ounce a day serving.





Designed to simplify supplementation. For horsemen that need a great vitamin supplement, a powerful hoof supplement, and a probiotic, Mega-Dose provides all by feeding just one supplement. We combine the vitamin-mineral-probiotic package of Horse Guard with “mega-dosed” amino-acids AND a super-powerful hoof-supplement featuring 32 mg of biotin per dose into one convenient feeding.

Mega Dose gives you the assurance that you are feeding the highest quality ingredients including chelated minerals, pharmaceutical-grade vitamins and food-grade carriers. Plus, because Mega Dose is formulated by a Certified Equine Nutritionist, you’ll appreciate knowing that your horse is getting exactly what they need for health – not too much of one nutrient, too little of another.

Solid nutrition is the basis of good health and performance:

Aids in Faster Muscle Recovery – Vitamin E and Organic Selenium helps to speed recovery and increase disease resistance

Promotes Shiny Coats & Healthy Hooves – Biotin, Methionine and Zinc are building blocks for healthy hair and hooves

Helps to Improve Digestion – Probiotics, Prebiotics and Yeast are powerful digestive aids

Promotes Improved  Overall Health – Balanced vitamins and trace minerals meet nutritional needs not fulfilled by your horse’s hay
