Vitamin D insufficiency is easy to test and correct. The amount of D3 required depends upon the degree of insufficiency (determined by testing), the patient’s species, weight, age, intact status, diet, and other factors. Testing is simple and cost effective using the VDI Vitamin D test

A blood sample from the patient is applied to a device and simply mailed by common carrier. The device easily crosses international borders without custom declarations. Dosing information is provided on the report with detailing the result and D3 dosing required for the cat or dog, along with recommended supplements that can be found at
