Our custom diets are diets formulated according to the research requirements of the customer. We can create a new formula based on customer specifications, reproduce a previously published formulation or modify any existing formula.

Research protocols may require dietary manipulation of micronutrient profiles to induce disease models or to investigate the mechanisms by which specific nutrients or compounds impact disease states.

Purified Diets:
The most common type of custom diet used for nutritional manipulation is a purified diet. Purified diets are formulated with refined ingredients such that each ingredient contributes primarily one nutrient. This allows for precise manipulation, customization and reproducibility of the diet’s nutrient composition.

Examples of Common Dietary Manipulation:

  • Fat type and level (diet induced obesity)
  • Protein and amino acid adjusted
  • Carbohydrate source and level
  • Vitamin and mineral content
  • Cholesterol (atherogenic)
  • Fiber source and level

Grain-Based Diets:
The most common type of custom diet used for the incorporation and delivery of medications and compounds is a grain-based diet. Adding compounds to a grain-based diet allows the medication to be delivered without having to deviate from their maintenance diet.

Examples of Common Dietary Manipulation:

  • Doxycycline
  • Tamoxifen
  • Fenbendazole
  • Pain Relievers (Carprofen, Meloxicam)
  • Cholesterol

Custom Diets Additives
Your supplied additives can be incorporated in either grain-based or purified diets. These diets are formulated to include test compounds such as medications, nutraceuticals, food ingredients and preclinical compounds to allow for convenient and accurate low-stress dosing.
