80 year old arteries at age 37 … 15 year old arteries at 72 years of age!. Joe used the results of the research he conducted together with three pharmacologists (who subsequently won the Nobel prize in medicine for their research on Nitric Oxide and its vital cell signalling properties) to create a treatment program for atherosclerosis and circulation restoration. Dr. Joe was able to reverse his own life threatening problem with atherosclerosis completely.

Why We Age – The Role for Anti-oxidants and Arginine Dr Joe discusses the ageing process and how Antioxidants, Arginine, Citrulline and Nitric Oxide have a vital role to play in slowing the ageing process and improving life quality.


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.

L Arginine, Citrulline and Nitric Oxide accelerate the healing, improves the outcome and returns the patient to a normal life more rapidly after a heart attack. They also promote the reversal of the atherosclerotic plaques of cardiovascular disease.


Dr. Joseph Prendergast is an endocrinologist who specializes in the treatment of diabetes and cardiovascular disease. He serves on numerous boards including the California Medical Review Board, and he recently received an award from the American Medical Association for his humanitarian efforts. He has published more than 40 scientific papers and has lectured extensively in the United States and is considered to be one of the foremost leaders in his field.

Dr. Joe reversed his own problems with atherosclerosis completely … his arteries went from those of an 80 year old at age 37 to those of an 15 year old at age 72!

He then applied the same treatment to all of his own patients (80% of whom are diabetics) with absolutely amazing results. NOT ONE of his patients has been hospitalised for circulatory problems, heart attacks, strokes, peripheral neuropathy, gangrene, amputatations in over 17 years since he started applying the treatment to them … this is absolutely unheard of !!
