Purina® Amplify®
High-Fat Supplement

Amplify Supplement

Easily added to a horse’s daily ration, Purina® Amplify® High-Fat Supplement is nutritionally balanced and designed to provide multiple benefits, including weight gain, optimal skin and hair coat, and support of healthy hooves.

As a high-fat, controlled-starch extruded nutritional supplement, Amplify® Supplement can be used when extra calories are needed to maintain your horse’s body condition.

Weight gain

Amplify® Supplement provides extra calories to promote healthy weight gain and maintenance, particularly for horses that have difficulty keeping weight on, hardworking and competitive horses, stallions, and pregnant and nursing mares.

Shine and Bloom

Essential fatty acids promote optimal skin and hair coat, making Amplify® Supplement perfect for preparing horses for showing and sale.

Muscle Performance

Amplify® Supplement contains amino acids to help promote muscle growth and antioxidants, including vitamin D, that help address the damaging effects of free radicals on your horse’s appearance. Protein, vitamins and minerals maintain the nutritional balance of a horse’s total ration when added to a concentrate feed and forage diet.

Shawn Flarida, the National Reining Horse Association’s first-ever Four Million Dollar Rider, talks about why professionals choose Amplify® Supplement for their prized performance horses that need additional support for weight gain, muscle performance and appearance.


At Purina, we’ve spent more than 100 years developing superior nutrition for horses. After numerous scientific formulations, trials and refinements for our new line of supplements, we’ve found ways to give horses the boost they need to be their best. No more trying to find a supplement that works. No more frustration and expense for ones that under-deliver.

Amplify® Supplement IS available in a 30-pound
pail or 50-pound bag.

Begin with a 1 pound per day feeding rate; gradually increase by 0.5 pounds/day every two days until the desired feeding rates are achieved. Begin feeding 60 days prior to competition, sale, show or breeding season. Maximum feeding rate for most horses should be 4 pounds of Purina® Amplify® Supplement per day. Horses have varying acceptance of higher-fat diets and supplements, and as the fat level in the diet is increased, some horses may begin to show diminished intake. If that occurs, reduce the feeding rate or try blending Purina® Amplify® Supplement with a small amount of sweet feed. When fed as recommended, Purina® Amplify® Supplement will provide no more than 0.3 ppm selenium to the total diet.

If your horse is sensitive to dietary soluble carbohydrates, please consult with a veterinarian or nutritionist for a recommended diet.

Changes in feeding programs should be made gradually over a period of 10–14 days. Adequate forage is necessary to maintain normal digestive function in the horse. Provide a minimum of 1 lb. per 100 lbs. body weight per day of hay or the equivalent in pasture. Prevent the rapid eating of any feedstuffs by the horse. Observe your horse’s condition daily and consult your veterinarian immediately if any problems arise. Amplify® Supplement is to be used as a supplement. Amplify® Supplement is not to be used as an ingredient in manufacturing feed.

Follow label directions. Feeding added selenium at levels in excess of 0.3 ppm in the total diet is prohibited. Store in a dry, well-ventilated area protected from rodents and insects. Do not feed moldy or insect-infested feed as it may cause illness or death. This product was made in a feed manufacturing facility that does not handle or store products containing animal proteins prohibited in ruminant feed.
