What is a Nutritional Therapy Practitioner?


Nutritional Therapy Practitioners are integral members of the holistic health community. We believe a properly prepared, nutrient dense whole food diet sets the ultimate foundation for optimal health and healing. We work in concert with your other medical care providers to find areas of deficiency or imbalance in the body, and correct them. We find these deficiencies through a thorough assessment including a functional evaluation. We address these weaknesses through a whole food nutrition and supplementation protocol. Nutritional Therapists know that there are other important factors for health outside the scope of nutrition. We are here to help you find balance as you work towards your nutritional goals. Nutritional Therapists use an approach that is science/evidence based down to the cellular level.


What is the difference between a Nutritional Therapist a Registered Dietician?

Dietitians hold degrees in dietetics. Primary Doctor’s tend to refer patients to an RD if the individual is struggling with obesity, diabetes, failure to grow in children, or other conditions where they believe medical dietary intervention may help to control a condition. They would help change the diet (usually based on western medical dietary guidelines) in order to control the condition.

Many medical Doctor’s do not link disease with diet so people find they have to seek help elsewhere. For example, an individual who is always fatigued may get a diagnosis like chronic fatigue or depression, and get treated with medications to help control the issue. Nutritional Therapists focus on the link between health and nutrition, with an emphasis on identifying the root cause of a health problem, rather than trying to keep symptoms at bay or suppress the condition. For example, fatigue may be because of unstable blood sugar, or a thyroid issues. Once the root cause is identified, nutritional therapists help come up with a nutritional plan that may include supplement recommendations to help fix underlying cause of the symptoms.

The payoff of hiring a Nutritional Therapist is that you will have the tools necessary to heal your digestion, balance your blood sugar, increase your energy, increase your self awareness, decrease inflammation, feel younger, stabilize your moods, and the list goes on and on.

Some of the symptoms I can address as a Nutritional Therapist:

  • fatigue
  • joint pain
  • irritability
  • moodiness
  • frequent hunger
  • sugar cravings
  • indigestion/heartburn
  • other digestive issues such as colitis and constipation
  • skin problems
  • food sensitivities
  • weight gain or inability to lose weight
  • autoimmune conditions
  • hormonal issues

“Before working with Kathryn, I felt very out of touch with my body and what it was trying to show me. I was lethargic, cloudy, fatigued and overall just felt very ‘blah’. Kathryn was very thorough with her assessments and recommendations and I am now well on my way to a much happier, vibrant and healthy life. I feel excited to continue on this journey and am so thankful to her for her compassionate expertise. She is truly a master of her craft!”-Theresa


“I was diagnosed with hypothyroidism several years ago and had gotten used to the idea that I would always be on medicine, I would never have energy, and my life just wouldn’t be what it used to. But I heard about Kathryn through a reputable business that i frequented and thought it might be worth a try. She was very nice and made me feel comfortable discussing all of the issues I was having. She is obviously very educated and well-informed about nutrition, but it was her personal experiences with an auto immune disease that really made me trust her. She is willing to work at whatever pace her client needs, and for the first time in a long time, I had hope that things could be different. Kathryn immediately got me started on a regimen of supplements with a guideline for foods to avoid and consume, but she also suggested multiple cookbooks and other reading materials so I could learn more about why I was making these particular changes. I felt confident in her approach and within weeks, I had more energy than I could remember. I appreciate how available she makes herself in between appointments, via email and phone- it makes me feel like I’m not in this alone and helps me make better choices on a daily basis. I would highly recommend Kathryn to anyone looking to better themselves through nutrition and wellness, but specifically, I wish everyone who was ever struggling with an auto-immune disease had the opportunity to work with her. In just a short amount of time, it has changed my life.”- Katie

About Kathryn:

Kathryn Kos is a Nutritional Therapy Practitioner (NTP)  through The Nutritional Therapy Association, and a Certified Lactation Educator/Counselor through The University of San Diego. Her undergraduate degree is in Movement Science from Westfield State College. Her Master’s degree is in Rehabilitation Counseling from Springfield College.

“My own health struggles occurred through years of following mainstream western nutritional advice led me down this path. I was eating what I thought was a very healthy diet (following conventional medical advice). However, I was struggling with feeling good inside and out. I ended up being diagnosed with several Autoimmune Conditions. I was having horrible gall bladder attacks and living on antacids. My thyroid was enlarged, and I struggled with anxiety and insomnia. My endocrinologist wanted to wait until my thyroid stopped functioning, and put me on a medication. That was the only solution offered. Doctors wanted to put me on medications. My philosophy is to find and heal the root cause of the problem, rather than fix the symptoms by taking a medication or removing an organ. Through my own intense research, I began my real food journey. My health changed drastically and my autoimmune markers went way down. I started to feel amazing and wanted to share my experience on a big level. I am so excited to share my knowledge with you!  I am dedicated to helping you realize what your bio-individual nutrition needs are, and giving you the tools to make positive changes in your life!” -Kathryn Kos, NTP

  1. I didn’t know you went to USD. It’s a beautiful campus – and city. Way better than New York 😉

  2. I’m sure this relates to hormonal issues but do you address fertility issues?

    • primalblissnutrition says:

      Hi there, yes, I can address fertility as well. It is very much tied in with hormonal balance.
