Highly knowledgeable and skilled, Dr. B demonstrated a keen understanding of my body's specific requirements from the outset. Through the implementation of a tailored nutrition plan, I successfully shed 18 pounds in a span of one month, all without resorting to traditional exercise routines or engaging in strenuous physical activities. Surprisingly, I found myself consuming a greater quantity of food than usual; however, it was the strategic selection of appropriate foods at precise intervals that proved instrumental in my weight loss journey. Dr. B and the entire staff at the clinic exhibited exceptional professionalism and expertise. Rather than merely recommending Dr. B to my family and friends, I hold them accountable for not availing themselves of such remarkable services.

I discovered HNNH when I was diagnosed with Stage 1b HER2 positive breast cancer and I wanted to explore an alternative healing process. Dr. Bier has been the most helpful medical professional I have ever experienced in my 63+years. Not only has helped me through the breast cancer without chemo or radiation, he has given advice on many other issues that have come up and I always appreciate his perspective. I'm not sure I would be alive today if I had followed my oncologist's prescription because I believe I had to get to the root cause of my health problems in order to heal for the long term. I'm 4 years out from my diagnosis and I am healthier than I have ever been. I highly encourage anyone to give him
a try.

Dr. Bier has been the most thoughtful care provider I have ever worked with. He is great about a holistic view of the body, and frequently relies on peer reviewed medical literature to support his recommendations and treatment protocols. The office staff is friendly and helpful. Everyone there is a joy to work with.

My case was complex, and I truly believe my survival was greatly enhanced by Dr. Bier’s insight and care. I have since moved 150 miles away, and continue to work with him as my life continues to improve.

Simply put, I have never received better treatment from a practitioner in my life! And I have been around, battling multiple autoimmune conditions and other chronic health problems for the past ten years. Never have I ever felt so seen and heard by a doctor, and NEVER have I ever been so healed! (To add to the superlatives, never have I been more impressed by a doctor's clinical and holistic knowledge, either. Basically my response to this entire practice is, "Wow. I wish I had found this place sooner. And I wish that everyone I know could come here.)
On my first visit, Dr. Bier spent almost three hours with me. It was the most comprehensive and thorough exam I have ever experienced. Dr. Bier does not jump to conclusions nor dismiss symptoms; instead he took me in with curiosity and expertise, and evaluated me as a full person, rather than just a bundle of amorphous symptoms. He created a treatment plan, an entire booklet that covered diet, supplements, labs, and healing treatments that he recommended to me. Everything that he recommended made sense, and I understood what needed to happen to heal my body. He did a really good job explaining what was happening inside me, and I finally felt like I had found a practitioner who had the skillset to heal a complicated case like me. (Actually, while traditional doctors have suggested that I am a complex case, Dr. Bier has reassured me that my symptoms are relatively straightforward and simple to reverse. I just had never had the proper treatment to address the underlying causes of my disease.)
I am now 8 weeks into my treatment, and when I think about Human Nature Natural Health, I almost cry with gratitude. Because I can't believe I finally found the type of medical practice that could heal me, on both a physical and emotional level. I no longer feel like a living dead person, I am healing and growing back into me again. And the entire staff that works with Dr. Bier are incredibly open-hearted and brilliant. I look forward to every visit I have, and I hope that more people explore this life-changing medical practice.

I was looking for a Naturopath specializing in oncology in the Boston area and received a recommendation for Dr. Ian Bier in Portsmouth NH. I came to Dr. Bier after my colon resection operation for early stage 3 colon cancer. I underwent a short chemo treatment but was forced to stop due to severe side-effects. I had diabetes which was managed with medication. Dr. Bier gave me a new diet and a regime of appropriate supplements. He is very knowledgeable and personable. He was able to communicate to me the relative benefits of the treatments he had available. The protocol he developed for me has helped to strengthen my immune response and overall health. After one year I am now testing in the normal range for A1C without medication and will soon be diabetes free. My blood work is consistently in the normal range for all functions and my colonoscopy and CT show me to be currently cancer free. I believe that Dr. Bier has made a great contribution to my health. He is also a wonderful person.

My world was jolted when I heard the word cancer, especially after priding myself on taking the very best care of myself ….at least I thought I did!
It’s now been 3 years and 10 months since breast cancer surgery when,  shortly after, I investigated Human Nature Natural Health, concerned about the side effects of the radiation treatments and hormone therapy that I was directed to receive as the “next step” in my treatment.

I laid out my concerns to Dr. Bier during a phone consult and discovered a doctor that was patient, attentive, brilliant, and who offered me treatment options that weren’t riddled with side effects.   
During my first visit we discussed not only my post-surgery treatments, but also my chronic ailments of localized dermatitis, general body aches, seasonal allergies,sleep disruptions and chronic afternoon fatigue. Dr. Bier explained and then outlined in detail a treatment, diet and supplement regime that has changed my overall health.
It was astonishing to report at my follow up visit that all these chronic ailments were gone,a visible testament to my treatments, diet modifications, and supplement protocol.

Aside from consulting on my post cancer health, Dr. Bier also fit me into his busy schedule to treat me for acute sciatic flare up which felt like I was being electrocuted! He treated me with acupuncture and then sent me home with liniments and a pain solution that helped me tremendously.
Dr. Bier will always be my first choice to consult with and provide natural treatments for other active outdoor lifestyle ailments that come my way. I trust Dr. Bier with my overall health as I journey cancer free through my ever so blessed senior years with my family and friends. I confidently recommend Dr. Bier to my friends and family with the assurance that he and his kind and knowledgeable staff will provide them with the same respect and quality care that they have provided me for the last three and a half years.

I traveled halfway across the country to see Dr. Bier, and it was the best decision I've ever made for my health. He was able to gather a great amount of facts about the state of my health with ease, and with extensive knowledge and insights was able to put together a plan for me to recover. He was very honest, practical, and simply made sense. He wasn't guessing and trying out things, like all other "traditional" western doctors have done to me. He gained my trust very quickly. I am only on the second day of taking the suppliments and adjusting my lifestyle, and I'm already noticing changes in my health. Best of all, he found a way to get my body to sleep without horrible prescription drugs!

I was very impressed with the day I spent at his clinic getting treatments done. This involved detoxing in an infered sauna and through fango, a chiropractic adjustment, and acupuncture. If I were living in the area I would go back for more of these treatments right away, but I'm looking forward to them when I visit him again. My dad said I looked 18 again after I came home from the treatments, because the giant bags under my eyes went away I looked more "fresh." I did feel more energized after the treatments, and this is significant to me when I've been fighting dehibilitating fatigue for a while. I have seen a chiropractor regularly for about 5 years, and he accomplished more in one adjustment than the other chiropractors have. His acupuncture was very effective, and I had no pain from the needles like I'm used to from my regular acupuncturist.


I highly recommend Dr. Bier, as he quickly got to the root issues in my body when no other "traditional" western medicine doctor has been able to. I've had doctors poison me with their "guess work," and I have no fear of that from Dr. Bier.

I made an appointment because of my up-and-down roller-coaster energy issues, and before I could tell Dr. Bier what was wrong with my energy, he was able to tell me that I had burnt out my adrenal glands, and to compensate for the low energy I was eating massive amounts of sugary+starchy foods which spiked my blood sugar levels, which is why my energy would go up and down quickly. I was doing a lot of damage to my pancreas, and I had digestive problems and mucus issues (caused by dairy), and a lack of protein. He created a customized diet+supplement regime for me, and I'm slowly but surely starting to feel a little better with each passing month. I thought I knew a lot going into my first appointment, and Dr. Bier was able to dispel all of my misconceptions and explain why in ways that made perfect sense. Don't believe everything you read on the Internet! There's a lot of misinformation out there!
I highly, highly recommend!
