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.

Dr. Iris is a wonderful and caring doctor.

"Dr. Iris is a wonderful and caring doctor. I have been fortunate enough to be her patient since 2012, when my large toddler was causing havoc on my back. She was easily able to get me out of pain and back to functioning order and has been doing so ever since.

She has an amazing intuition when it comes to the body. She is able to find the little spots that are out of alignment, even if I'm not able to locate them myself, and put them back where they belong.

She is completely committed to her patient's well being and will do everything in her power to make you well, body and mind!"

I experienced miraculous results after visiting Dr. Rosenfeld.

"My back for no apparent reason was so painful.  I couldn't move.  After two days in bed a friend recommended I see Dr. Rosenfeld.  I could barely drive or sit when I came in.  This had happened several times in the past twenty years.   A medical doctor had given me muscle relaxers only.  They weren't all that helpful but over time and with restricting activities I got better.  I experienced miraculous results after visiting Dr. Rosenfeld.  I am able to do more than before in movement and strength with no pain, my whole outlook each day is more positive and I feel more energized."

I have had issues with headaches and back pain for many years.

"I have had issues with headaches and back pain for many years.  In addition, I have had problems with general pain issues.  I had been treated by two other chiropractors, a physical therapist and a medical doctor.  I would get a bit better but then improvement stopped.  I had heard of Dr. Rosenfeld so I decided to make an appointment.  I have to honestly say that I have been feeling much better in a consistent manner.  The headaches are now rare and my body just feels better!"

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."

After seeing Dr. Rosenfeld, I have no pain in my neck and great mobility.

"I first came to the office in 07/07. I came to the office because of pain in my neck and shoulders that I have had on and off for years. I also had very limited mobility. In the past I have been treated by other chiropractors with only temporary relief. We changed insurance plans and after much research I called Dr. Rosenfeld. After seeing Dr. Rosenfeld, I have no pain in my neck and great mobility. There is still some aching in the shoulder, but the mobility is much improved."

I am being treated by Dr. Rosenfeld for pain relief.

"I am a law enforcement officer.  I had middle back pain like a pinch under the left shoulder blade area.  This limited me from working out and running.  I was very conscious at work with regard to my profession.  I had heard from a friend that chiropractors thoroughly studied the spine, concentrated on one discipline as opposed to western medicine.  I am being treated by Dr. Rosenfeld for pain relief.  Because of the long hours of sitting in a radio car or long hours standing and the approximately fifty pounds of gear I wear on a daily basis, I don't have the small aches and pains I used to have. I have talked to several of my co-workers who complain of back pain and told them to consult a chiropractor.  I have also told them about some of the other services Dr. Rosenfeld provides."

I was really impressed with the advanced equipment and techniques

"In April of 2008 I was struck by another car while driving and felt my neck snap and muscles in my upper body pull and tear. When I woke up the next day I had a migraine and was so stiff I could not walk. Dr. Iris saw me immediately and began working on me. I was really impressed with the advanced equipment and techniques she uses on accident victims. She eliminated my headache in the first visit and got me walking without pain quickly. I would never see or recommend another chiropractor as long as Dr. Iris is still practicing. She is such a wonderful person and talented professional."

With Dr. Rosenfeld I felt comfortable that she would take care of me.

"I had a neck injury seven years ago and have continued to have periods of bad times.  I recently had a knee replacement which threw my back and neck out to the point I could not walk.  I lost my job, can't work and can't work out.  I just felt down.  I had a bad experience with a chiropractor a long time ago.  With Dr. Rosenfeld I felt comfortable that she would take care of me.  Within a couple of visits I could walk and the pain was not so terrible and now we are working on the neck to try and relax it.  I also use the natural products as well as the exercises given to me by Dr. Rosenfeld to try to get the best results.  When I feel better life is better and everyone and everything is better.  I tell people to try chiropractor care because if they try it they will be surprised."

Since seeing Dr. Rosenfeld, I have had progressive improvement

"I first came into the office in January 2008. I had a chronic issue with burning tightness in the right hip, extending to the middle back. It began about 10 years ago. I believe it was progressively getting worse but started with having a more sedentary job. It was not debilitating, but was annoying most of the time. I had been to my family doctor, an orthopedist, and another chiropractor. With the other chiropractor I had moderate results. The MDs had little to offer and no idea how to help. I found this office via a web search on the internet. Since seeing Dr. Rosenfeld, I have had progressive improvement, but the supplemental therapies have been both helpful and entertaining."
