I am so grateful to work with Radhia during the process of making changes in my life. Radhia was professional, kind and informative. Her expertise, personal attention and support was critical to ensure my optimal health. I know that if I have issues or questions re my health in the future Radhia will be the person I can count on for guidance and answers. More...

Radhia is a phenomenal nutritionist. She is honest, direct, brilliant and compassionate. I saw her when my hormones and my adrenals were way out of balance. I had no energy and my inflammation was off the charts, so I was in chronic pain and sensed I was headed towards some kind of illness. She helped me find balance and reduced my inflammation and I am now pain free and back on a healthy trajectory. I trust her opinions above most doctors and have since sent many a client to her for help, especially for treatment of auto-immune issues. I highly recommend Radhia to anyone needing to find answers that mainstream doctors cant seem to give. What I especially like and trust is that she uses various tests (blood, urine, stool or saliva) and also looks at your general practitioner tests-synthesizes the information THAN works to balance your system. She is thorough and I feel looks at the entire picture and seeks to find the solution not just the band-aid treatment you may get from your general doctor. She also educates her clients about their bodies and what is going on that is creating an issue! Highly recommend! More...

Radhia is a brilliant practitioner, truly an expert in her field. She listens well and has consistently been able to address issues with which we have come to her. I have known Rhadia a long time and am consistently amazed with the wealth of knowledge about the physiology of the human body she brings to the table. More...

Radhia is very thorough, she listens well and is extremely knowledgeable and has a fun sense of humor. I feel confident in her care and with the protocol she has implemented for me to alleviate arthritis inflammation.

I have anxiety disorder, and Radhia has been able to help me control that with alternative supplements that don't cause me as many side effects as the medicines that work for me. I still take some medications, but in reduced quantities, so the side effects are lower. More...

I live in Fort Worth, but have phone consultations, and even private consultations on Zoom, with Radhia all the time. She always makes time for me; her service and expertise has been invaluable! Her product knowledge is amazing and her recommendations have proved to be spot on. Over the years, she has worked with me on pain management, sleep issues, bone density, digestive issues, hair loss, and my overall nutritional needs, as well as making recommendations for my boyfriend in an effort to help get him off some of his prescription medications. Basically, I can't say enough good things. Thank you Radhia! More...

Radhia has been a God send for us. She’s helped us when many Doctors could not. I’ve sent all of my friends and family to her and we will continue to use her for a lifetime. Very grateful we crossed paths.

When I was exhausted from overwork, Radhia helped me with all the tests needed to discover my Cortisol levels were blown (and adrenals) she worked diligently with me for months, managing my protocols to help me raise my endocrine system back to normal. Plus, as you see, I learned a lot about self health care from her, during this time. She's a wealth of knowledge, and I have referred friends to her because of that. I am happy to give her a great review. More...

Radhia is amazing!! She is kind, patient, and very knowledgeable. She has a wonderful sense of humor which immediately puts you at ease. Her knowledge about the body and mind is outstanding. I have been working with her for the last several months to balance various deficiencies in both minerals, vitamins, and hormones. Radhia recommended rigorous testing and even worked with healthcare specialists to determine what supplements would work best to make me feel "like me" again (without interfere with other medications). I have been taking the supplements and following her advice and the changes are becoming evident everyday. I would highly recommend Radhia to anyone who is tired of conventional doctors telling them everything is "fine", when inside you know it's NOT "fine". Radhia has given me the opportunity to see what is going on inside my body in a way that conventional medicine (and insurance companies) doesn't offer. I look forward to keeping up with the regiment and regaining my sense of self and my health! You won't regret a moment you spend learning and healing with her! More...

I have worked with Radhia on various health issues over the last 30 yrs, she is so knowledgeable and continues to learn, sees things in patterns rather than symptoms . I would and do recommend her regularly and trust her with my health. More...

I was visiting with Radhia about a current issue I had been dealing with for several months. She asked me a few more details and recommended some changes/additions to my supplements, advised me on how to take them, told me it may take awhile to resolve but to be patient. Within a couple weeks I noticed a difference and I continue to improve each day. I was under a doctor's care but with Radhia's help my health has greatly improved. Radhia is amazing! More...

Radhia has helped me so much to find the vitamins I needed for all phases of my life, trying to get pregnant, pregnant, breast-feeding, then no sleep, lol. I love the interesting facts she types up for us to take too. She recently also helped a friend of mine get some good basic items for what she needed. More...


I wrote a book entitled : The Natural Health Detective, (yet to be released). The introduction is entitled : How the Body Works, The 4 Pillars of Health. There are 4 pillars to health. 1) Digestion, 2) Absorption, 3) Utilization, and 4) Elimination. You're only as strong as your weakest link, and weakness in any of those four will inevitably lead to disease. I believe conventional medicine is not "health care" but disease management and should be secondary not primary medicine. Nutrition should be your primary healthcare.

I love my clients. I love teaching and inspiring them to take control over their own health and wellbeing. And I especially love it when they come to me and say, "You changed my life". And even better when they say "You saved my life." That get's me up in the morning.

I owned a clinic for about 20 years. But 10 years ago, I took a job as the Wellness Director for a compounding pharmacy. I liked the security of a paycheck every month, but I realized that lending my 30-plus years experience and intellectual property to someone else is a false security. The only true security I have is in myself. I love working with people, solving their health challenges in one-on-one interactions.

I am a Certified Clinical Nutritionist, not a dietitian. I'm a Biochemical Analyst, and more importantly, a Holistic practitioner. I am trained in much more than making meal-plans. When it comes to a disease symptom, I investigate like Sherlock Holmes. I am trained to use many tools such as bio/neurochemical and genetic analysis just to name a few. I search for the underlying cause of one's symptom, not just cover it up with a Band-Aid. To help someone restore their health back to balance is the greatest reward.

Remote consultation is the greatest gift. It allows me to reach a broader field and also avoid having to always have a brick and mortar facility. I love it.

If you are local to Austin, I am happy to see you in person at my office at the pharmacy. But remote online consultation has made it so much more convenient and safe.

Treating a symptom without uncovering the real cause is like placing a piece of black tape over the blinking red warning light.

Get the customized nutritional support you need through neurochemical/hormone tests and assessment.

Where DNA-based lifestyle and supplement recommendations, complemented with optional questionnaire and lab data, are easy and efficient to make for a truly personalized approach. We utilize PureGenomics® with patients who already have their 23andMe® or Ancestry® data, turn to nutrigenomics for certain health concerns, or are just beginning to learn and explore. We support your needs for an easy and efficient personalized approach to your plan of care. When we're closer to our healthiest selves, we're one step closer to the goodness within.

Our body has a daily elimination cycle mostly carried out at night and in the early morning up until breakfast. However, when we eat a congesting diet higher in fats, meats, dairy products, refined foods, and chemicals, detoxification becomes more necessary. The decision to detoxify is based on individual lifestyle and needs. Cleansing or detoxification is one part of the trilogy of nutritional action; the other actions are building or toning, and balance or maintenance.
Let Radhia help you decide which cleansing program is right for you. Heavy Metal and Petrochemical tests available.

Forget about sorting bottles. You’ll no longer need to remember when, how much, and what to take.
Your customized supplements are all presorted according to Radhia, your healthcare practitioner’s directions and clearly labeled for you at no extra cost, drop-shipped directly to your door.

In this way, if people have imbalances (physical, emotional, or spiritual) in their lives, it can negatively affect their overall health. Holistic medicine is based on the belief that unconditional love and support is the most powerful healer and a person is ultimately responsible for his or her own health and well-being. Other principles of holistic medicine include the following:
All people have innate healing powers.
The patient is a person, not a disease.
Healing takes a team approach involving the patient and doctor, and addresses all aspects of a person's life using a variety of health care practices.

Treatment involves fixing the cause of the condition, not just alleviating the symptoms.
