Expert Nutrition

The special EXPERT NUTRITION dog foods have been developed in accordance with the most demanding nutritional requirements for pets. The food is based on the best quality, highly digestible ingredients and an overall composition using a single primary protein and a single source of carbohydrates, which lowers the likelihood of allergic reactions to the food. Our underlying philosophy calls for a high proportion of meat and high nutritional value.

The recipe’s functional components are always a bonus – they are not added at the expense of the quantity of meat or other basic ingredients. Furthermore, we use fulvic acid as a functional additive across the entire EXPERT NUTRITION line.

Fulvic acid is a group of organic acids originating in organic matter in the soil and which are part of humus. Fulvic acid is part of the natural diets of animals in the wild, and it has a range of positive effects on the body. It supports the absorption of nutrients from food and stabilizes intestinal microflora. It has antioxidant and detoxification properties – as it absorbs toxins and heavy metals and helps the body eliminate them. Anti-inflammatory effects and modulation of the inflammatory response have also been ascribed to them. The recipes are free of wheat, soy, maize, artificial colorings and preservatives, and contain no genetically modified organisms (GMOs).
