Functional medicine at TONIIK looks for the root cause of how you feel: hormones, thyroid, metabolism, heart health and nutrients, backed by comprehensive specialty testing that goes well beyond standard labs. We use the results to build a clear, customized plan for your health.
The Institute for Functional Medicine describes functional medicine as a systems biology approach that focuses on identifying and addressing the root cause of disease. In plain terms, it means looking at the whole picture instead of treating each symptom on its own.
In practice, that means longer visits, a detailed health history, targeted lab work and a plan built around nutrition, sleep, movement and stress, with medication or hormone therapy when it’s needed. Functional medicine works alongside your primary care doctor, not instead of them.
TONIIK is a nurse practitioner led practice at 12210 Ventura Blvd in Studio City, and we see patients from Sherman Oaks, North Hollywood, Encino, Burbank and across Los Angeles.
The research is still growing, and we think it’s worth being honest about what it shows. The first study of its kind came from Cleveland Clinic and was published in JAMA Network Open in 2019. It looked back at the records of 1,595 patients seen at Cleveland Clinic’s Center for Functional Medicine and compared them with 5,657 patients seen in primary care.
At six months, 31% of the functional medicine patients had a meaningful improvement in their physical health scores, compared with 22% in primary care. At 12 months the improvements held up, but the difference between the two groups was no longer statistically significant. The researchers called for more studies, and we agree. For us, the value is in the model: more time, more detail and a plan you can actually follow.
Estrogen, progesterone, testosterone, cortisol and DHEA all affect energy, sleep, mood, weight and libido. We use blood work and DUTCH hormone testing when it adds useful detail. For women in their 40s and 50s, and for men and women with low hormone levels, see our hormone replacement therapy and menopause care.
About 5 in 100 Americans have an underactive thyroid, and Hashimoto’s disease is the most common cause. It’s 4 to 10 times more common in women than in men. A full thyroid workup looks at TSH, T4, T3 and TPO antibodies, not just TSH alone.
Blood sugar, insulin and body composition all play into energy and weight. When weight is part of the picture, we can build in a medical weight loss program.
Advanced lipid markers like ApoB and Lp(a) can add detail to a standard cholesterol panel when assessing cardiovascular risk, and a Cleerly heart scan can show plaque directly.
Depending on your symptoms, we may look at micronutrients, gut health or other markers using the specialty and biomarker tests covered on this page.

Comprehensive testing goes further than standard lab work. It examines areas like your gut microbiome, immune reactions to foods, micronutrient absorption, hormone levels, and exposure to toxins. These tests reveal patterns and issues that routine checkups often miss.
For those dealing with persistent fatigue, bloating, skin issues, or mood swings, this type of testing can be a turning point. Instead of guessing, we use data to make decisions. It gives you and your provider clear direction based on your body’s actual needs.
At TONIIK, we use these results to build focused wellness plans that reflect your unique health picture. The goal is clarity, not trial and error.

Functional medicine is an approach that looks for the root cause of symptoms by looking at how your body’s systems work together, including hormones, thyroid, metabolism, nutrition, sleep and stress, rather than treating each symptom on its own.
The main differences are time and depth. Visits are longer, the health history is more detailed, testing is often broader, and lifestyle is a core part of the treatment plan. It works best alongside your primary care doctor, not as a replacement.
Patients commonly come to us for fatigue, hormone changes, perimenopause and menopause, thyroid problems including Hashimoto’s, weight gain, poor sleep and low libido. Many also come for prevention and longevity.
The research is still developing. A 2019 Cleveland Clinic study in JAMA Network Open found that functional medicine patients had larger improvements in physical health scores than primary care patients at six months, though the difference was not significant at 12 months. Individual treatments we use, like hormone therapy and thyroid treatment, follow established clinical guidelines.
No. Functional medicine works alongside your primary care doctor. We’re happy to share results and coordinate care.
Comprehensive specialty testing goes beyond standard lab work to uncover the root causes of chronic symptoms and imbalances. These tests assess gut health, food sensitivities, micronutrient deficiencies, toxin exposure, hormone levels, immune activity, and more, helping create targeted, personalized wellness plans.
It depends on your symptoms. Common ones include a full thyroid panel (TSH, T4, T3 and TPO antibodies), sex hormones, DUTCH hormone testing, blood sugar and insulin markers, advanced lipids like ApoB and Lp(a), and nutrient levels.
At TONIIK, we believe in getting to the root of your health concerns, not just managing symptoms. These advanced tests provide deeper insights into your body’s systems, guiding customized protocols for true healing and long-term vitality.
Gut Microbiome Analysis
A full-spectrum gut health test that detects over 300 species of bacteria, fungi, viruses, and parasites. It evaluates digestion, inflammation, microbiome balance, and leaky gut markers.
Food Sensitivity Testing
Identifies IgG and IgA immune reactions to a wide panel of foods (96 to 288 items). It helps uncover hidden food triggers contributing to inflammation, skin conditions, digestive issues, or fatigue.
Micronutrient Testing
Assesses over 40 essential vitamins, minerals, amino acids, and antioxidants at the cellular level, revealing true deficiencies and absorption issues.
Mold & Mycotoxin Testing
Screens for mold toxin exposure, a common but overlooked cause of fatigue, brain fog, sinus issues, and inflammation. Useful for those with water damage history or persistent unexplained symptoms.
Tickborne Disease Testing
Detects Lyme disease and related co-infections that may not show up on conventional tests. Helpful for patients with chronic fatigue, joint pain, or neurological symptoms.
Neurological Autoimmunity Panel
Identifies early autoimmune reactions in the brain and nervous system. Screens for antibodies linked to brain fog, memory issues, mood disorders, and neuroinflammation.
Autoimmune Screening Panels
Looks for immune dysregulation in specific body systems like thyroid, gut, nervous system, and connective tissue. Useful for early detection before a full autoimmune disease develops.
Wheat and Gluten Reactivity Panel
Tests for gluten sensitivity, wheat allergy, and autoimmune markers like celiac disease, along with leaky gut indicators. Ideal for those with bloating, brain fog, or skin conditions.
Hormone Panel
A complete analysis of estrogen, progesterone, testosterone, cortisol, DHEA, and more. Helps identify imbalances contributing to fatigue, mood swings, weight gain, or low libido.
Environmental Toxin and Heavy Metal Testing
Measures stored levels of toxins such as pesticides, plastics, and heavy metals like mercury and lead. Essential for patients with detox issues or unexplained chronic symptoms.
Advanced Cardiovascular Risk Panel
Includes markers like oxidized LDL, Lp(a), ApoB, hsCRP, and homocysteine to assess early cardiovascular risk beyond a standard lipid panel.
These tests use microarray and advanced sequencing technology that allows for greater sensitivity and accuracy. They can detect patterns and markers that typical bloodwork can’t, and often require only small sample sizes.
Depending on the test, you may provide a blood, stool, urine, or saliva sample. Some tests can be completed at home, while others are collected in-office at TONIIK. We guide you through each step and handle the processing for you.
Most specialty tests are not covered by insurance, but we provide transparent pricing and flexible options. The insight gained often saves clients time, money, and years of trial-and-error guessing.
Results typically return in 7 to 21 business days, depending on the test. Once your results are in, we’ll schedule a consultation to walk you through the findings and design your personalized care plan.
Yes. These advanced labs are designed to be interpreted by trained functional medicine providers. At TONIIK, we analyze your results in the context of your lifestyle, symptoms, and goals to build a strategic, holistic plan for optimal wellness.

MJ and the entire Tonik team have been absolutely incredible! They’ve helped me identify exactly what was missing for me to truly feel my best and have supported me in getting my thyroid and gut health back into balance. They’re so attentive and thorough, even with me being out of state, and I’ve felt so cared for throughout the entire process. I’m beyond grateful I found them! ❤️

You just don’t get care like this at a gp appointment. This is hyper focused, incredibly personal, and wildly educational. You learn things about your unique needs that have been shrouded in mystery and vague ideas your whole life and it’s super empowering to be given that intel so freely and compassionately. MJ is the best at what she does and everyone in the office is super sweet, warm, and professional. If you’re looking for functional care this is your place!

My virtual visit with MJ was everything I was hoping for and more! From the moment I scheduled my appointment, her staff was incredibly kind, responsive, and supportive. They guided me through every step of the process, stayed in touch, answered all of my questions, and made sure I felt comfortable before my visit even began. During my appointment, I truly felt heard—especially because I can talk a lot!

This is long over due and MJ deserves more than 5 stars. She has been amazing for the past few years ever since I found her on IG. I've had laser treatments, peels and she provided me with the most amazing skin care that have helped keep my melasma away. I started with the sunscreen which I do apply every 2 hrs when I'm outside or on vacation.

I have been working with MJ on a weight management plan for the past three months. Despite my efforts to exercise and eat healthily, I struggled to lose weight. We conducted blood work to check my hormones, and based on the results, we made some adjustments, including adding vitamins. MJ also started me on semaglutide. The process has been gradual, but I’ve lost a total of 17 pounds. MJ helped me develop better eating habits, and I feel amazing!

went in today for my Dysport treatment and the entire experience was fantastic from start to finish. MJ is literally the cutest, and I mean that in every way — from her sweet, welcoming personality to the genuine care she puts into her work. She took the time to understand exactly what I wanted and made me feel completely comfortable throughout. Her technique was precise and gentle, and I finally feel like I’ve found my go-to nurse!

I had my CO2 laser treatment at Toniik today and had such a great experience! MJ made me feel completely relaxed and comfortable throughout the entire process. I’m already super excited to see my results. I truly love this place — everyone that works here are incredibly sweet and welcoming. The space itself is trendy, cute.

I’m so grateful to have found Toniik! My best friend referred me and I will forever be a customer! I suffer from a rare condition called dystonia (cervical dystonia) which affects the muscles in my neck… I can’t control my neck movements, which can cause my neck to essentially have a mind of its own. I was in complete spasm before seeing MJ.
