Public Service Announcement:

If you don't test, it's just a guess. My background is in human biochemistry and microbiology. If you would like a real look at your labs, not just the lab ranges but the true physiological (optimum/non-optimum) ranges, I can provide that or order blood, stool, saliva, and/or urine tests for you - at my cost to you. You only pay for my time interpreting and going over them with you. It may be the best investment in your own health you've ever made. Please call me at 714-639-4360 for more information.

Labs Results Below - This is a 32-year-old male who reached out to me for symptoms related to post-concussion syndrome. I ordered labs before our initial consultation. Initial labs on 10-11-24 showed very high levels of three enzymes related to tissue breakdown. On his intake forms, the patient denied smoking, drinking, drugs, or exposure to chemicals in the workplace. I questioned him more thoroughly, and he admitted to using ni****ne pouches for about 3 years.

I tailored a protocol to support liver function and advised him to stop the pouches. He said he would have to taper off of their use as he felt dependent on the ni****ne. I ordered labs 30 days out. Below are the before and after labs.

The takeaway is that even if a product, any product, is available over the counter (OTC), it does not mean it is safe. If this young man had not consulted me for his PCS, he would never have known he was killing his liver.

"Dr. Ettinger not only healed my husband who was for several years with terrible case of HPylori and doctors were unable to detect why my husband was soo sick. My husband says this is the best he has ever felt in his entire life. Dr. Ettinger also healed my sister who has dealt with Lupus and chronic illness since 12 years old. She never looked soo good in her whole life. He is a miracle worker he is currently treating me for Potts and a chronic bacteria, keeping me from healing doctors have not been able to find out what's wrong with me but by the grace of God, Dr. Ettinger has found the problem.

Seriously soo grateful we met him we always send everyone we know to get treated by him. For those who don't believe in hollistic approach it's time to start. This man is a medical detective and he truly changed our lives. Thank you Dr. Ettinger."

"Dr. Ettinger helped me with my digestion issues after three Gastroenterologists failed. His prices are reasonable and doesn't try to sell you on any of his products. The blood test he recommends is very comprehensive and I plan on having it done yearly. I highly recommend him if you have digestive issues."
