Custom diets are developed for a specific purpose and benefit from your input and our expertise
Determining the most appropriate diet for your research model can be challenging, but we are here to help. With more than 20,000 unique formulas in our database attained over 40 years, Inotiv nutritionists have vast experience to draw upon.
To meet the progressive demands of science and to serve you better, we continually add to our database as we acquire new knowledge.
Common uses for custom diets include
- Control nutrients
- Vitamin or mineral adjusted
- Protein or amino acid adjusted
- Lipid or fatty acid adjusted

- Atherogenic (cholesterol, fat, cholate)
- Diet-induced obesity (40-60% kcal from fat)
- High carbohydrate (fructose, sucrose)
- NaCl adjusted
- NAFLD and NASH
- Cuprizone demyelination
- Dose animals
- Control gene expression — doxycycline or tamoxifen containing diets
- Addition of customer-supplied ingredients/compounds
- Others
- Basal mixes
- Isoflavone adjusted
- Rabbit, swine and other species
- Diet ingredients
Diets and ingredients
You can select from the wide variety of existing diets, or one designed specifically for your purposes. Either way, we encourage you to contact us for complimentary consultation with our nutritionists.
A small number of representative custom research diet formulas are found on our website. If you are unable to find a product code or formula description cited in a publication, or one used previously by your lab or others, contact us.

Learn more about different types of custom diets
Purified diets
Purified diets are the most common type of custom diet. They are made with refined ingredients such as casein, sucrose, corn starch, fat, oil, and cellulose. These high-quality, food grade ingredients have relatively simple chemical compositions making it easier to manipulate individual nutrients. The use of refined ingredients provides uniformity and reproducibility benefits, and also serves to reduce variation due to natural substances that may have biological activity.
Common classes of purified diets include:
- AIN diet formulas
- Amino acid defined
- High fat for obesity (40-60% kcal from fat)
- High carbohydrate (fructose, sucrose)
- Vitamin and mineral adjusted
Standard diets with additions
You can use one of our complete standard natural ingredient diets from either our Global or Traditional lines to serve as the base for a custom diet. We can add various types of in-house ingredients such as doxycycline, tamoxifen, cuprizone, cholesterol, lithium, carbonyl iron, vitamin E, aspirin, ibuprofen, and more. We also routinely add customer-supplied ingredients.
Natural ingredient diets
Custom natural ingredient diets are formulated using the same agricultural commodities as found in our standard laboratory animal diets. These include corn, wheat, soybean meal, alfalfa meal, fish meal, and other agricultural by-products. These ingredients have relatively complex and variable chemical composition, and thus their use in custom diets is limited. The NaCl adjusted series for rodents are one example of custom diets in this category.
Hybrid diets
Hybrid diets are a mixture of natural and refined ingredients. This type of blended formulation is sometimes necessary to limit specific nutrient or non-nutrient substances. The inclusion of some natural ingredients can enhance palatability of a hybrid diet, particularly for rabbits and guinea pigs.
Customer-supplied ingredients
You may have a specific additive that you would like us to include in one of our purified, standard, natural ingredient, or hybrid diets. Upon review of safety information, we can do that for you. It is often a convenient approach for dosing research animals. Some of the additives you may consider include food extracts, antioxidants, anti-inflammatory agents, fatty acids, pharmaceutical drugs, and many more. See customer-supplied ingredients to learn more.
