Despite the wide variety of ingredients it contains, a home-cooked diet is still deficient in numerous minerals and vitamins such as calcium, copper, iron and vitamin A. There are two main reasons for this.

The ingredients used, whether raw or cooked, do not contain enough of these nutrients, even when served in the right quantities.
Cooking food causes a partial loss of nutrients (e.g. vitamins). The V-Integra supplement is specially formulated to compensate for these deficiencies, providing all the vitamins and minerals that dogs and cats need on a daily basis, and making the homemade diet complete and balanced.
