Health of a pet starts with the quality of food they eat. It’s why we so often look to diet for general wellness, and for the management of acutely ill animals. Nutrition serves a critical role in patient care, and improving diets often helps our pets live longer and healthier lives. Unfortunately, too many commercial diets are inadequate in many of the essential vitamins and minerals needed by the animal.

The Vitamin D Example

Vitamin D is a perfect example. As one of the essential vitamins, it’s only obtained through the cat or dog’s diet. Sure some diet’s are better than others, but in general are cats and dogs getting enough?

A study out of Tufts University showed a wide range of pet food brands were insufficient in providing adequate Vitamin D.

The Case For Testing

Unlike AAFCO standards, which indicate and regulate Vitamin D3 added to food, testing an animal is required to see what the actual biologically available Vitamin D concentration is in a particular pet. As the study above demonstrated, the resulting testing shows consistent insufficiency.

Another thing to keep in mind: we’ve all heard the old saying “if some is good, more is better,” however when it comes to essential vitamins, this isn’t true. The body is a finely tuned machine with vitamins and hormones existing in a balance. Too little and problems can develop. Too much and other problems can arise. This is what makes testing such a critical part of managing diet & essential vitamin levels. Dial in the supplementation by Test – Treat – Test.

A simple blood test can tell you what the Vitamin D status is, but testing through VDI also offers a secondary value: Dosing Guidelines.

Dosing guidelines are specific to the patient and are intended to supplement the current diet. Since every animal is different, with different needs, there is no “one-size-fits-all” approach to supplementing essential vitamins. Getting just the right amount using the Test & Treat approach is the best practice for managing essential vitamin levels.

The Case For Testing with VDI Laboratory

VDI Laboratory offers a low-cost, convenient blood test for Vitamin D status. Once the level is determined, the lab report goes on to provide patient specific dosing requirements and then converts those to a recommended supplement that has known efficacy. It’s this complete Test & Treat solution, that makes correcting Vitamin D insufficiency simple.

Patient Specific Dosing Guidelines take into account multiple factors of the patient to develop a targeted dose range. The goal is to reach sufficiency with supplementation on the first try.

Once the dose range is established, the doses are then converted to a recommended supplement that has known efficacy. VDI partners with reliable manufacturers to provide optimal Test & Treat Solutions.
