Welcome to PETROVIC CFIDS Health Center

The Petrovic CFIDS Health Center (formerly Longevitas Health Center) international web sites was first launched in the USA in 1995 , as one the world's first web sites on Chronic Fatigue (Immunodysfunction) Syndrome ( CFIDS / CFS / ME). It is also one of the most comprehensive sites on CFIDS/CFS/ME and the most effective and curative treatment for this extremely serious and complex physical illness /syndrome.

Dr Nash Petrovic MD was the first physician and medical researcher in the world to launch his novel free radical etiological concept of Chronic Fatigue (Immunodysfunction) Syndrome as an operative and optimal clinical and therapeutic basis for treatment of this syndrome as well as for treatment of various auto-immune entities (Ulcerative colitis, Chron's disease and systemic lupus erythematosus ) and/or entities that include an autoimmune component (asthma ). In fact, the Petrovic CFIDS Health Center is the very first and currently the only medical center in the world that has clinically verified full and permanent reversal of potentially fatal Chron's autoimmune disease in all randomly selected CFIDS/Chron's disease patients via the ultimate medical clinical verification procedures ie biopsy and histological examination before and after treatment on the CFIDS Protocol as confirmed by completely independent medical centers in both RSA and Australia.Dr Petrovic's extremely effective therapeutic approach based on his novel medical technologies is also specifically referenced to in international bestseller " Explaining Unexplainable Illnesses" published by Prof Dr Martin Pall, Dept. of Biochemistry, Washington Medical University.

Based on this concept the original modality of the CFIDS Treatment Protocol for post viral and other forms of chronic fatigue was formulated according to the best pharmaceutical standards in 1994.


The current modality of the CFIDS Protocol contains a very high number of synergistic components and is the world's most successful and comprehensive treatment for Chronic Fatigue ( Immunodysfunction) Syndrome. This highly effective treatment that is based on a revolutionary, molecular therapeutic concept is many technological years ahead in comparison with any other protocol or treatment approach for CFS /CFIDS /ME) that are developed in the USA , EU and/or any other countries in the world.

New research clearly demonstrates that this Protocol is also the most effective immunomodulatory therapeutic approach. Apart of impressive clinical reversal of CFS (CFIDS /ME), The Petrovic CFIDS Protocol was found to be highly effective in patients suffering from various auto-immune entities as well. Impressive curative effects ans most encouraging therapeutic responses are observed in patients with auto-immune diseases such as Chron's disease, ulcerative colitis and systemic lupus erythematosus as well as in all categories of patients with impaired and dysfunctional immune responses, inclusive of patients with asthma, MCS (Multiple Chemical Sensitivity Syndrome) and GWS ( Gulf War Syndrome).

Due to its regenerative and energising effects, the CFIDS Protocol is also the most potent age reversing procedure that is suitable for use by top athletes, active business people, models and actors as well as for all other professionals and generally speaking, all individuals who wish to keep their optimal energy level, young appearance and optimal professional performance for many years ahead or who wish to reverse the effects of aging.
