Abstract: The invention relates to the fields of application of health, biotechnology and nutrition, the aim of the invention being to provide a gelatinous mixture of probiotics and prebiotics with synergic symbiotic action for the treatment of chronic renal disease, the characteristics and components thereof reducing the concentration of uremic toxins, improving the renal function of the patient with an increase in urea, creatinine, uric acid, p-cresols or indoles in the blood. The gelatinous mixture of probiotics and prebiotics with synergic symbiotic action for the treatment of chronic renal disease is easier to administrate orally as it does not require the consumption of liquids for the administration thereof, reducing liquid retention. Another advantage of the present invention is the fact that it refers to live and active bacteria. The present invention is also used a primary source of food with known prebiotic effects, an element which is not considered in other inventions; it is not in a pharmaceutical form.
