Over the last few years I have struggled with high histamine related issues due to mold toxicity and Ruth has been my faithful source of wisdom on how to not only help lower my histamine responses but also locate the root cause to find complete healing. Ruth knows first hand the difficulty and overwhlmeing feelings of trying to find good health again because she has been through it herself. The empathy, compassion and understanding she gives while simultaneously offering direct and honest wisdom and care is unmatched. I would not be where I am today if it were not for her care and help. It’s so fun to rejoice with her when I notice my energy levels increasing or being able to smell a candle or eat eggs again without a reaction. So thankful for all her help.

I can't thank Ruth enough for helping me turn my health around over the last six months. I've been dealing with fibromyalgia symptoms for the past 4 years including fatigue, pain, mental fog, and sleep problems, as a result of breast cancer treatment. Ruth taught me Stretching exercises that have eliminated my whole body pain and improved my energy levels. Before working with Ruth, my pain and fatigue were getting worse and worse. The stress and tension in my body were building up, and on most days, my entire body would hurt and I was exhausted. Once I met with Ruth, I noticed the benefits of stretching right away and I've been practicing the stretching DAILY ever since, to keep my body feeling great. In addition to stretching, Ruth taught me calming and breathing exercises which trained me to relax and reduced my day-to-day anxiety. Thanks to the Stretching and Calming exercises, my body pain is now down to zero on most days, and even my TMJ pain improved because I learned how to relax my muscles and breathe. I never imagined that I'd be able to get to where I am today. I now have my life back because I have the energy to do the activities I used to struggle with. I learned from Ruth that there's HOPE of getting better through holistic health coaching. Ruth is gentle and an amazing teacher. Ruth is so caring and generous with giving you her time and attention. She listens well, has genuine interest in learning about what you're experiencing and offers strategies that might help. I highly recommend working with Ruth if you want to feel BETTER and improve your quality of life.

When I came to Ruth for help I was having trouble when I ate food, it felt as if I had a brick in my stomach. Bloated and as if my food would get stuck, it was quite scary!! I also was having Bowel issues. I worked with Ruth for a little over 2 months, not only did All this issues I was having get resolved but other unexpected things happened. My sleep is better, Energy Level better, My pickle ball game has improved!! (: My cravings for sweets have lessened. I don’t feel deprived!! (That’s a big deal for me) Ruth Believes in a Balanced Diet, her Plans are so easy to follow, it’s exciting to see Results almost immediately!!! Ruth is also very knowledgeable about Panic Attacks, Low energy. All which I have had bouts with for years!! The Nervous System Stretches she Teaches have helped me with my Moods, They keep me Calmer, much better than any Vit/Herbs I have been taking. They literally make me feel I can wake up and Conquer My Day. On a side note… she has also helped my husband with his heart burn, a issue for years, now completely gone!! I cannot say enough about her Kind, Generous, Giving Heart!!! She makes you feel you are the most important person when working with her!!! She truly cares about giving people a New Lease on Life!! I can’t thank her enough!! I would give her 10 stars if I could!!

Ruth is exceptional. After turning 50, weight gain, hot flashes, fatigue, joint pain, anxiety and depression were a daily battle for me. I was eating "healthy" for the most part. After filling out Ruth's intake form, questionnaire and having a consulting call, she went to work! Doing what she does best, she took all of my symptoms, food intolerances and reactions into account to see how they all came from the same source, high histamine food intolerance and leaky gut. All of the spinach, avocado, tomatoes, green beans, vinegar and other healthy foods were causing my health issues! At first it was hard for me to believe, but I wanted to get better so I followed her eating plan and supplement recommendations. In two months I was 20 pounds lighter and free from all of my other symptoms! I am still in the process of healing my leaky gut, which may take at least a year, but the cloud has lifted and I am back to enjoying my life. I kept hearing from people that all I was suffering from was normal for women in menopause. Ruth proved them wrong! A major bonus you get when working with Ruth, she prays with you and for you!

I have to post a review for Tru Nutrition, because I would never have thought myself capable of adjusting my eating habits, but Ruth Causly has managed to coach me through a whole program and then help me develop and sustain some deeper habits. What I love about her approach is that she first sits down to really listen and understand and target specific health issues. I have struggled with migraines and headaches for years, and I never realized how tied they were to my diet (which also affects hormones). She tailored my program to my health needs, and then she coached and educated me through the whole thing. Her follow-up, positive encouragements, coaching, ideas, suggestions, instructions, were all amazing and demonstrate how she herself was very much personally invested in my success. Unexpectedly, through this program, I also discovered how much my energy level had been affected by my eating, so that by the end I felt not only more energy and focus, but my body's physical thresholds changed as well. (Another plus: my waistline decreased.) This does require some hard work and commitment, but Ruth is just as committed, and as it's already been some time since I finished, I anticipate these life-changing results are here for the long-run.

Ruth is amazing! Over the last few years, I had started developing hives on a daily basis. I went to multiple allergists and they could not figure out what was going on. Before I began working with Ruth, I was on 2 Zyrtecs per day and Benadryl— not good! In addition, I had daily headaches and lethargy. Initially I thought all these symptoms were due solely to a very busy, stressful life. Yet, I was suspicious that it could be something else. So glad I reached out to Ruth and worked with her. I noticed an immediate difference after the first week. Upon completion of her program, the headaches are gone, lethargy is gone (no need for coffee either— Starbucks is missing my $50 week!), I no longer have hives, and I accidentally dropped 20 pounds! Thank the Lord! I would recommend Ruth for anyone seeking to live a healthier lifestyle, and rid yourself of pesky symptoms associated with a variety of health conditions. So much comes from our gut! I have learned a lot and even know how to cook delicious meals that are healthy for me. (As a foodie, I was worried about this too!) I appreciate Ruth sincerely and I am so grateful for her program, she changed my life!

I have been on a rollercoaster with every diet imaginable and after much prayer and a look at Shari, I was introduced to Ruth. I would often lose weight but never in my upper stomach area. My stomach would always protrude. I would often look pregnant. Ruth walked alongside me and showed me properly how to eat. She also showed me how to read labels, make healthier choices and how to cook healthy. Ruth is dedicate, transparent and easy to talk with. I was able to recognize that gluten along with SIBO was causing the bloating, stomach cramps and the protrusion. I feel like after being under Ruth's tutelage along with the prayers... I can make this a lifestyle. Grateful Donna Cunningham

I hate exercising so I have always controlled my weight with diets. From calorie counting to Keto, I have been on back to back diets for the last twenty years. At age 51, the diets simply stopped working. On top of that I had chronic constipation, water retention and began developing a laundry list of food allergies. Ruth , who is all about healthy living, told me that being on eleven laxatives a day was NOT healthy and her goal was to get me off of them. My goal was to lose weight. So Ruth went to work on finding healthy foods that I liked and incorporated them into a personalized healthy plan to meet these goals. She was so patient and caring, finding ways for me to eat clean and healthy while still enjoying my food. Ruth even introduced strategies for me to eat at restaurants and parties so I didn't feel constrained and could still live life well. Ruth walked very closely with me daily. She was so detailed in her care for me that she actually discovered that my water retention, weight gain, food allergies and constipation were all linked to an undiagnosed medical condition that was breaking down my internal organs. The doctors had missed it for decades. God used Ruth’s expertise to save my life ! Now,I am happy with my weight , which has stabilized. The water retention, food allergies and constipation are rapidly decreasing and she even found an exercise regime that I love. That, alone, is a total miracle! I thank God for Ruth ! I am finally on the road to recovery!

After several years of back and forth visits to several different doctors with little to no answers, eczema flare ups, allergic reactions, and constant stomach aches, Ruth encouraged me to change my diet and incorporate specific supplements. With a daily, very specific food journal, Ruth was able to pinpoint what foods needed to be eliminated and what needed to be added in, in order for complete healing to begin. She helped me realize my anxiety was a big part of my problem, and then gave me scripture reminding me of God's promises (this was a turning point for me). What I appreciate most about Ruth is the fact that her treatment plan was specific to my body. Because my discomfort was very specific, so were my instructions for healing. Ruth has gone above and beyond to ensure I got my body back to 100%. She is encouraging and motivating. She will not allow you to give up on yourself, and she will not give up on you. And above all this, Ruth prayed for me! Constantly! And this is what sets her apart from other nutritionists, she gives it to God. She knows it's in His hands. In His time. I am beyond grateful❤️
