What is Nitric Oxide (NO)

Nitric Oxide (NO) is a naturally produced molecule that plays a vital role in the circulation that supports almost every biological system. However, your body’s ability to produce NO declines rapidly as you age.

Supplementing your diet with a consistent, quality source of dietary nitrates is an easy and effective way to boost Nitric Oxide levels and support overall health. Berkeley Life’s proprietary dietary nitrate blend provides the plant-based bioequivalents of 5oz of spinach and 7oz of beets in each two-capsule dose, helping you maintain healthy Nitric Oxide levels as you age.

Micro Circulation and Peripheral Neuropathy

We Love Our Clients!

Thank you for taking the time to read these reviews.

I would give 10 stars if I could.

"I would give 10 stars if I could.  Dr. Rosenfeld is the consummate professional!

If you want to get the best chiropractic care available look no further. I must receive impeccable care/service for me to write a review. Dr. Rosenfeld will increase your quality of life and reduce your pain. This is all done in a professional manner and setting. The staff is just as professional as Dr. Rosenfeld which is extremely important to me!  I have been to numerous Chiropractors and very rarely will I return for a second visit. My search took over 6 months to find the right Dr and care. And the office hours should accommodate anyone's schedule. 

Thank you Dr. Rosenfeld. I'm so excited to have found you!"

I have experienced relief, blessed relief!

"I have neck pain.  I recall various incidents that triggered it… reaching into a desk drawer, sleeping on a new pillow, etc.  I have seen other chiropractors and some helped and others didn't.  My mom introduced me to Dr. Rosenfeld and I have experienced relief, blessed relief!"

Dr. Rosenfeld is a very loving and generous doctor.

"Dr. Rosenfeld is a very loving and generous doctor.  I highly recommend her. She is always studying and learning new ways to help her clients.  Dr. Rosenfeld has a very long list of techniques that she can offer to help.  Dr. Rosenfeld is high energy and fun and an inspiration.  I am grateful that my 19 yo son is her patient since I want him to meet motivated professionals."

She and her staff go out of their way to try to fit you in for an appointment even if they are very busy

"Dr. Iris has been treating several members of my family for over a year now and we highly recommend her. I have been having chronic neck and back pain for several years and feel so much better after every adjustment. I also appreciate that Dr. Iris will recommend and provide vitamins or natural treatments for other health issues. She and her staff go out of their way to try to fit you in for an appointment even if they are very busy. She is very patient-oriented and is a fun and caring person to be around."

I've never quite felt that before any health practitioner that I can remember

"Just want say thank you for the extraordinary commitment I feel from you to my getting better. I've never quite felt that before any health practitioner that I can remember."

I chose Dr. Rosenfeld to help me continue on the road to good health.

"I had just moved to this area.  I had been seeing another chiropractor on a regular basis to help with knee problems and other aches and pains that cropped up.  After I moved I chose Dr. Rosenfeld to help me continue on the road to good health.  I had also received physical therapy for my knee.  Physical therapy worked well but only focused on my knee.  Chiropractic treats my whole body.  Other areas of my body need adjusting to help keep my knee functioning well.  I found Dr. Rosenfeld through the yellow pages.  I am now in my 5th year of chiropractic care and I wonder how I got along without it in the past.  My knee is doing well and I am continuing to run."

Previously I have seen a GI and an Allergist, with no help.

"I first came into the office on April 2007. I had food and environmental allergies. The allergies were moderate and caused mental fog, fatigue, stomach cramps and IBS. Previously I have seen a GI and an allergist, with no help. Because of the treatments I received here, I am 85% recovered. Most of the foods which caused troubles do not currently cause any symptoms."

Her patients come first there is no question about that.

"I have known Dr. Iris for over 15 years & in all that time she has never wavered from being not only a professional in her field, but treating you like a friend. She has always taken good care of me & made time to see me when I've needed her care. She is always on a quest to learn more & educate her patients so they can lead  healthy lives. Her patients come first there is no question about that."


I love coming into this office.

"I had tremendous pain in my lower back and neck.  I could barely walk or even function normally before I came to see Dr. Rosenfeld.  I had this condition on and off for years, but never to this degree that caused me to finally seek professional help.  I was given Vicodin, Soma and Naproxin by a regular family physician.  The medication only temporarily took away my pain.  I never had any other treatment other than a physician who prescribed me these medications.  One of my husband's friends spoke very highly of Dr. Rosenfeld so I called her.  I have gotten great results!!! I am finally recovering from my back/neck injury.  Dr. Rosenfeld and her entire staff have been extremely caring and helpful.  I love coming into this office."

I have my life back!

"I have suffered with sciatica issues my entire life and worsened when I was pregnant.  The severity was intense.  I saw a general practitioner but had poor results.  I found Dr. Rosenfeld through my insurance company and looked her up on the internet.  I have had excellent results… I have my life back!  Thank you from the bottom of my heart and back!"
