Nucleotides are bioactive compounds that serve as the building blocks of DNA and RNA. In pet foods they are often supplied from yeast-derived ingredients such as Saccharomyces cerevisiae. Nucleotides are critical for the renewal of rapidly dividing cells (intestinal mucosa, immune cells, bone marrow). They may be particularly useful in young animals, stressed individuals and immunocompromised patients. Since endogenous nucleotide synthesis is energetically costly, dietary intake accelerates cell renewal.

Nucleotides, It is a scientifically supported advanced functional ingredient. It is valuable for intestinal mucosa repair and immune support. Its presence in premium foods is an indicator of quality. It is a safe and beneficial supplement.
Why Added?
- Intestinal mucosa repair: Supports rapid renewal of enterocytes (3-5 day turnover)
- Immune support: Increases lymphocyte proliferation and antibody production
- Puppy development: Provides substrate for cell division during periods of rapid growth
- Periods of stress: Speeds up recovery after surgery, infection and intense exercise
Purine Content and Urate Stone
Nucleotides contain purine bases and are formed as a result of their metabolism. uric acid occurs. The risk of ammonium urate stones may increase in breeds with impaired uric acid metabolism, such as Dalmatian dogs. A low purine diet is recommended for these breeds. In other breeds, the amount of nucleotides in the food is within safe limits.
Frequently Asked Questions
Are nucleotides really necessary?
The body can synthesize nucleotides endogenously (de novo synthesis). However, this process is costly in terms of energy. Dietary nucleotide intake (salvage pathway) accelerates cell renewal, especially in rapidly dividing tissues. Dietary intake is more important in young, old and sick animals.
