Custom Formula Purified Diets

Making custom diets is our business. This is what we do. Our staff of scientists work daily with researchers from around the world to develop unique formulations for individual studies. Research Diets, Inc. has created over 19,000 "Original" formulas and is able to produce and ship custom diets in 5 to 7 business days.

Custom OpenSource Diets

Because these ingredients are refined materials, each containing one nutrient, (as opposed to the less refined chow ingredients) allows research nutritionists to define the nutritional requirements of animals, by selectively removing one nutrient at a time from the diet. This also means that the possible modifications one can make to an OpenSource diet are virtually limitless. This is also what continues to make OpenSource diets powerful research tools and why so many scientists have turned to them in recent years.

Talk with one of our nutrition scientists about your next project. Let us formulate the experimental and matching control diets to meet your specific study needs. Our conversations begin with discussions of the animal models being used, desired phenotype and dietary requirements. Next, our scientists will search the published literature to provide you with tools to make an informed decision on diet selection based on solid science. We will then formulate, produce and ship custom diets in 5 to 7 business days.

A Word of Caution

Don’t be misled by diet manufacturers who claim to offer the same OpenSource diet formulas as Research Diets, Inc. Though it is true that all our formulas are open, there may be differences in the sources of ingredients or the vitamin and mineral mixes used to produce the diet. There is only one sure way to repeat research based on the "Original" OpenSource Diet formula—go to the source of that formula. There is only one place to get OpenSource Diets and that’s at Research Diets, Inc.
