About Us

We promote global collaboration and knowledge exchange with veterinary and scientific thought leaders around proven nutritional science to help pets live better, longer lives.

It has never been easier for consumers to find information about pet nutrition, but finding reliable information is difficult. Nutrition can play a powerful role in pet health, which is why we need to put it to the forefront of our conversations.

We know that 83% of consumers completely trust their veterinarian to provide helpful information about the food they feed their pet. However, veterinarians only initiate the conversation around nutrition 22% of the time.

The Purina Institute will provide veterinarians with science-based information.

Imagining The Impossible

Our goal is not only to elevate today's nutritional conversations. We are also focused on the future and bringing to life the findings of Purina's R&D network, who every day imagines the impossible and unleashes the power of nutrition to help pets live better, longer lives.

Brain Health
Brain Health

Years of groundbreaking research by Purina demonstrates a strong link between nutrition and cognitive function in our pets.

Gastro Health
Gastrointestinal Health

Purina's research has resulted in scientific evidence that shows the importance of maintaining microbiotal balance. An imbalanced microbiotal can result in poor fecal quality and reduced immune function.

Molecular Nutrition
Molecular Nutrition

In order to identify opportunities for nutritional intervention. Purina starts by exploring the effects of nutrition on cellular and molecular processes using nutrigenomics, transcriptomics, proteomics, metabolomics, and metagenomics.

Weight Management
Weight Management

Purina has been at the forefront of veterinary research for almost a century, and has demonstrated how weight management and targeted nutrition can extend the healthy lives of our pets.

About Us 2
Connecting human and nutritional science

Being part of Nestlé, the world's largest food and nutrition research organization, there are many opportunities to explore the connections between pet and human health. By sharing expertise among our scientific teams, we have already been able to apply key learnings in areas such as probiotics and cognitive decline.

The Purina Institute will connect with the most innovative minds in pet health, promoting collaboration across the globe and facilitating an exchange of knowledge by:
Collaboration 1

Sharing nutritional discoveries in key areas at the forefront of Purina's ground-breaking research while leveraging expertise from Purina and its Nestlé affiliates.

Collaboration 2

Showcasing objective, fact-based information sourced from the wider scientific community on current trending topics across pet and human nutrition.

Collaboration 4

Supporting global initiatives to help advance the field of veterinary medicine and help improve pet health, such as sponsoring the World Small Animal Veterinary Association's (WSAVA) Global Nutrition Committee, One Health Committee and One Care Initiative.

Collaboration 5

Expanding on the 100+ existing global partnerships Purina R&D has by regularly convening round tables to elevate the voice of thought leaders on the latest advancements in pet nutrition, health and wellness the Institute's Conference and Education Facility in St. Louis, Missouri, US.


Hosting the Companion Animal Nutrition (CAN) Summit, continuing the company's nearly 25-year long legacy of convening veterinary thought leaders from across the globe.


Advancing Nutrition

Purina has been a pioneer in the science of pet health through research that not only resulted in more than 500 peer-reviewed publications and 7,000 granted and pending patents, but also resulted in breakthroughs that have redefined and shaped the understanding of pet nutrition.

We have been pushing boundaries of pet nutrition for nearly 100 years, and we continue to deliver new advancements today.

Explore some of the highlights below of Purina's contribution to the field of nutrition.

Body Condition

1993: Body Condition System is Developed

Purina creates the first widely used and scientifically validated body condition score system. The tool provides a simple method for estimating body fat coverage and determining a pet's optimal body condition, regardless of breed or body weight.

Hydrolyzed Diet

1998: First Veterinary Prescribed Hydrolyzed Diet to Nutritionally Manage Food Allergies

Purina research shows that denaturing proteins through hydrolsis makes it less likely to trigger an immune response. The result is the first clinical diet using only hydrolyzed proteins for dogs with food allergies.

Feline Diet

2000: First Diet to Manage Feline Diabetes with High Protein and Minimal Carbohydrates

Purina's work is revolutionary in addressing feline diabetes through a low carbohydrate, high protein diet. This breaks from traditional diets that typically use high fiber. A clinical study showed that 89% of cats fed Purina's diet had an overall reduction in insulin requirements, with 33% no longer needing insulin at all.


2004: First Diet to Apply Nutrigenomics to Help Manage Disease

The expression of multiple genes is altered in osteoarthritis, resulting in inflammation and the production of destructive enzymes. Purina identifies specific amounts of omega-3 fatty acids to help improve mobility. Clinical research confirms the efficacy of this nutritional intervention through a reduction in lameness.


2006: First Probiotic Supplement for Cats and Dogs in a Therapeutic Diet Range

Probiotics can help promote intestinal balance and a healthy immune system. Purina is the first to launch a shelf-stable probiotic supplement proven to enhance immune function and help manage diarrhea. 

Cognitive Function

2010: First Well Dog Diet Clinically Proven to Improve Canine Cognitive Function

At approximately age 7, the glucose metabolism in a dog's brain begins to change, affecting cognitive function including memory, learning and decision-making. Medium-chain triglycerides (MCTs) provide an alternative energy source for the aging brain. Purina research shows that feeding a diet with MCTs significantly enhances cognitive function in older dogs.

We believe there is no limit to what nutrition can do and that science is more powerful when it is shared.
