CKD covers a spectrum of different pathophysiological processes related to abnormal renal function and progressive deterioration of the glomerular filtration rate.
Keto-analogs capture nitrogen within the body and convert themselves into amino acids. This prevents malnutrition and reduces the workload of the kidneys to excrete waste products containing nitrogen, so that the CKD process is delayed and dialysis can be postponed.
Evidence-based medicine: The above claim has been confirmed through a double-blind, placebo-controlled study published in the Journal of Renal Nutrition which indicates that over a period of 9 months, the very low protein Urelog diet supplemented with ketoanalogues helps patients with CRF (chronic renal failure) to preserve GFR (for its acronym in English, glomerular filtration rate) and maintain the BMI. KA (keto-analogs) were safe and effective in slowing the progression of kidney failure and preserving the nutritional status of patients with CRF .
