What people are saying.

  • “For the past 20 years, Dr. Rud has been a steady and trusted part of my health journey. Nutrition Response Testing helped uncover things I never would have known otherwise, and the approach has always felt tailored specifically to me. I’ve seen real, lasting improvements — not just temporary changes — and I appreciate the focus on supporting the body naturally. It is rare to find this level of consistently, care, and dedication over such a long period of time. Highly recommend!”

  • “I cannot say enough good things about my experience with Dr. Chris. After struggling with perimenopause and mood fluctuations that prescription medications were not improving, I decided to try a nutritional approach — and it made all the difference. The recommended supplement regimen truly helped when nothing else seemed to. What stood out most was the knowledge, compassion, and care I received. Dr. Chris and his wife take the time to listen and understand my situation. I am incredibly grateful for their support and highly recommend them to anyone feeling stuck or looking for alternative care.”

  • “I came to SCV Optimum Nutrition as a next step after standard medical tests didn’t seem to get to the root of some issues I was having. I found what Dr. Chris does with Nutritional Muscle Testing to be very helpful and a way to identify some possible issues and treatments that could help in a relatively short period of time. He is also honest if he doesn’t know the answer to questions and is willing to research possible answers.”

  • “St. Croix Valley Optimum Nutrition helps support my health by identifying my body’s unique nutritional needs. I count on Dr. Rud’s depth of knowledge to help keep me feeling my best. He and Ann are kind people who care about you personally. I wouldn’t be without them.”

    — Aletha S

  • "After a primary care physician wanted to prescribe Ozempic instead of running a blood panel to test my hormones for chronic fatigue, gut issues and chronic pain, I knew I needed to look elsewhere for answers. I found Dr. Chris and I have never looked back! Anytime my body tells me something is off, I know who to call. Thank you Dr. Chris for giving me my energy back to keep up with my three kids!"

  • "My health has changed drastically in the last 13 years I've known Dr. Chris. From, the very beginning, his compassion and commitment in finding solutions to health concerns goes above and beyond. I have been on this NRT journey with him since the very beginning. In many different situations and concerns, he has been able to assist in finding the right supplements that my body is needing. If you are on the fence, or even curious if he can help, I whole heartedly would advise oyu to try it. NRT has changed the game of health care and prevention!!"
