In purified diets each mineral is obtained from a discrete primary source allowing very close control over total mineral content, including "salt" or sodium.
We can easily formulate a "sodium-deficient" and "no sodium added" diet, achieving a diet sufficiently low in sodium to produce animals exhibiting the characteristic signs of sodium deficiency by omitting sodium from the formulation*.
Listed below is a typical series of diets used in sodium research. Using TestDiet® #5755 Basal Diet as the control diet, the sodium level can be increased and/or decreased to offer a carefully controlled range of sodium levels for study.
These are just a few examples of the hundreds of purified sodium-deficient diets we can formulate. We have the expertise to modify any diet with any specified level of a particular mineral. These diets shown are for rodents; sodium-modified purified diets are available for any species of laboratory animal.

*Note: Because of trace amounts of minerals from other ingredients, often it is quite difficult if not impossible for us to create an absolutely "sodium-free" diet. Even if the amounts of sodium may be below measurable levels, we would be reluctant to certify that it was absolutely free sodium.
