Dr Joe has found that supplying arginine, citrulline and vitamin D to patients with kidney disease prevents the disease from progressing and helps to reverse the condition. A patient in his 70's with type 1 diabetes (since he was 4 yrs old) developed kidney failure after a botched operation and was placed on dialysis. With Dr Joe using the arginine, citrulline and vitamin D treatment and the highly skilled young nephrologist conducting his dialysis and kidney treatment, the patient was able to come off dialysis as the kidneys healed.
