I lost my brother to traditional psychiatry. That's why we are building Meru Health Advanced.
I founded Meru Health ten years ago after losing my brother Peter to suicide.
My family didn't lose Peter because he gave up. We lost him because traditional psychiatry couldn't help him get better. Worse than that, the antidepressant treatment he was prescribed only made him worse.
I decided to do something about it. I wanted to build a better solution, one that helps people actually heal, instead of just managing their symptoms without ever getting to the root cause of what's wrong.
Peter was not an outlier. As I dug into the real-world evidence, I realized that roughly 30 to 40 percent of people with mental health conditions are labeled "treatment-resistant", a phrase the field uses to describe the patients it has failed. Tens of millions of people walk around with the same story my brother had. They try one medication. It doesn't work, or it makes things worse. They try another. They switch psychiatrists. They see a therapist on one side of town and a prescriber on the other who never speak to each other. They learn to stop hoping.
Mental healthcare, as it exists today, was not designed to help these people. It was designed around fifteen-minute visits, reimbursement codes, and the assumption that a pill taken daily can be optimized in isolation from the rest of a human life.
Through my own experience as a biohacker, and through my previous company in diabetes care, I had already seen what happens when you treat a chronic condition as a whole-person problem instead of a single-molecule one. Diabetes didn't get solved by better insulin alone. It started to get solved when we added continuous glucose monitoring, behavior change, nutrition, sleep, movement, when we stopped treating the pancreas in isolation and started treating the person.
Mental health deserves the same shift. And for the past decade, Meru Health has been quietly building it.
Today, we take the biggest step we've ever taken toward that future. I want to tell you what's broken, what we've learned from 40,000 patients, and what we are launching to replace it.
What's actually broken
If you have never been inside the mental health system as a patient, let me describe what "care" usually looks like.
You call to find a psychiatrist. You wait weeks or months. When you finally get in, you are given a fifteen-minute medication check. The clinician asks how you're feeling on a one-to-ten scale. They adjust a dose or switch a prescription. You leave with a plan that is almost indistinguishable from the plan given to the patient before you and the patient after.
If you are lucky, you also have a therapist. That therapist works at a different practice, uses a different chart, and has almost no visibility into what the psychiatrist is doing. The two people supposedly coordinating your care have often never spoken to each other. You are the integration layer. You, in the middle of a mental health crisis, are expected to hold the whole treatment plan in your head.
You are rarely asked what you eat. You are rarely asked how you sleep. Your metabolic health, your inflammation markers, your nutrient deficiencies, your thyroid, your hormones — the things every other specialty would check first, are almost never tested. Your nervous system, your trauma history, your movement, your breath all get filed under "lifestyle." And lifestyle, in conventional psychiatry, is treated as a nice-to-have, not as medicine.
When standard treatment doesn't work, the field has a name for you: treatment-resistant. I have come to believe that phrase is a confession. It admits that the model itself runs out of options after the second or third prescription. It does not admit that the model might be too narrow to begin with or that it might actually be using the wrong model altogether.
Traditional mental health care misses four of the most important drivers of recovery: metabolic health, sleep, behavior change, and integrated care. Every other field of medicine has moved toward measurement-based, personalized, whole-person treatment. Cardiology. Oncology. Diabetes. Mental health is the stubborn exception. We still trial-and-error with molecules in fifteen-minute increments and call it precision.
That is what we are working to change.
Why no psychiatrist draws your blood
Here is a question I've asked hundreds of audiences that usually lands hard:
When was the last time a psychiatrist or primary care physician ran your bloodwork before prescribing a psychiatric medication?
For almost everyone, the answer is never. And that is extraordinary, because the symptoms we call "depression" or "anxiety" can be produced, worsened, or maintained by things a basic lab panel would catch. Thyroid dysfunction. Severe B12 or vitamin D deficiency. Iron deficiency. Inflammatory markers elevated enough to drive depressive symptoms on their own. Blood sugar dysregulation and insulin resistance. Hormonal imbalances. Nutrient gaps that make it biochemically difficult for the brain to produce the neurotransmitters that antidepressants are trying to modulate.
Imagine a cardiologist who prescribed statins without ever looking at a lipid panel. You would never see that cardiologist again. And yet this is the default in psychiatry. We start with the pill and skip the diagnosis.
Meru Health Advanced begins at the opposite end. Every patient who joins gets two comprehensive psychiatric diagnostic visits paired with a comprehensive lab panel, over 30-50 biomarkers covering metabolic, hormonal, nutritional, inflammatory, thyroid, and cardiovascular health. Most psychiatrists run zero biomarkers. Even at psychiatric hospitals, patients are really only screened for being high, pregnant, or infected. We run more than any other mental health program in the country.
We look at the body before we prescribe for the mind. If something physiological is driving the symptoms, we address it directly through personalized nutrition, lifestyle medicine, or medical treatment before, or alongside, any psychiatric medication. As our Chief Psychiatrist Dr. Doug Emch puts it, we prioritize data-informed treatments and lifestyle changes to achieve lasting results, treating continuous medication as a last resort rather than the primary entry point for care.
The fact that we are starting with a real diagnosis instead of a symptom rating, changes almost everything that comes after.
What we've learned in ten years
When we started Meru Health, the idea that a 12-week program pairing every patient with a dedicated therapist, alongside a daily app-based practice covering CBT, mindfulness, education on sleep, nutrition, and exercise, and continuous heart rate variability biofeedback, could produce outcomes on par with conventional care was controversial. Ten years and more than 40,000 patients later, it isn't.
Our published research tells the story. Seventeen peer-reviewed studies, with collaborators at Stanford, Harvard, UCSF, UC Davis, the University of Washington, and Rutgers, have validated the model across age groups, across symptom severity, across patients with medical comorbidities, and out to twenty-four months after treatment. The outcome we are most proud of is this one:
Within two to three months of starting treatment, 55%-67% of Meru Health patients achieve a 50% or greater reduction in depression symptoms. For comparison, SSRIs achieve that in roughly 19 to 33 percent of patients and traditional psychotherapy in about 41 percent.
A higher response rate leads to fewer relapses, fewer disability claims, fewer inpatient admissions, and lower total healthcare costs. An independent actuarial study by Accorded, analyzing 1,306 Meru-engaged members against matched controls from 2021 to 2023, found 55% fewer inpatient admissions, 31% fewer ER visits, and 23% lower prescription costs, with the largest savings concentrated in members with chronic comorbidities. In mental health, that combination of clinical and economic outcomes is rare.
What we've learned from those patients is humbling and clear. The ones who do best are not the ones with the fanciest medication cocktails. They are the ones whose care is coordinated, whose progress is measured, whose lifestyle is treated as part of the prescription, and whose providers actually talk to each other. The variables that move outcomes are not exotic. They are integration, measurement, and the whole person.
We've also learned where our flagship 12-week Meru Health Therapy program runs out of runway. Meru Health Therapy pairs every patient with a dedicated therapist and teaches the fundamentals of diet, sleep, and exercise alongside CBT, mindfulness, and HRV biofeedback. For the majority of our patients, that is enough. But for the most complex ones — those who have already failed two or more medication trials, who carry comorbid conditions like diabetes or chronic pain alongside their depression, or who are managing bipolar disorder, PTSD, OCD, or treatment-resistant depression, therapy and lifestyle education alone are not enough. They need a psychiatrist who understands metabolic and lifestyle medicine. They need comprehensive bloodwork that tells them what is actually driving their symptoms. They need supplements targeted at the specific deficiencies those labs reveal. They need a dietitian translating lab results into an actual eating plan. And they need a care team that operates as one, with no information silos and no gaps between providers.
Until today, that combination has not existed in one place. We decided to build it.
Introducing Meru Health Advanced
Today, we are launching Meru Health Advanced, a precision, whole-person psychiatry and therapy program for the most complex mental health patients: treatment-resistant depression and anxiety, serious mental illness, and mental health layered on top of chronic physical illness. It is the 6 to 12 percent of the population that today drives 30 to 50 percent of total healthcare spending, and whom the current system has failed most completely.
What a patient actually gets is a coordinated team built around them:
A psychiatrist practicing measurement-based, metabolically-informed care, starting with two comprehensive diagnostic visits and a comprehensive lab panel. A dedicated therapist working within the same platform, with full visibility into the psychiatrist's plan and the patient's data. A dietitian providing tailored nutritional intervention — moving past general education into hands-on protocols like keto, low-carb, and anti-inflammatory diets where clinically appropriate. A care navigator who keeps the whole plan moving and coordinates with the patient's PCP and other providers.
Every Meru Health Advanced patient also receives a Whoop Peak wearable device that provides continuous 24/7 data on sleep, activity, exercise, and stress. This is the piece the field has been missing for decades. If continuous glucose monitoring was the breakthrough that unlocked personalized diabetes care, continuous biometric monitoring is its equivalent for mental health. The care team no longer works from a once-a-month snapshot. They work from a real-time signal.
And underneath it all, the Meru Health digital platform we've refined over a decade: daily evidence-based practices in CBT, mindfulness, and behavior change, plus a dedicated HRV biofeedback device patients use alongside the Whoop to train nervous system regulation in real time.
The program runs for 6 to 12 months. Six months of intensive, structured care, followed by six months of continuing support. Medication management where appropriate, including careful tapering where appropriate. Supplements targeted at the exact deficiencies revealed by lab testing. A peer support group moderated by a trained professional. An exercise prescription with follow-up. And the app as the connective tissue — video calls, chat, data from wearables, between-session practices that turn a once-a-week appointment into a daily practice.
One plan. One team. No silos. And a clinical model that starts with a real diagnosis and ends with measured outcomes.
This is why I believe Meru Health Advanced represents a paradigm shift. Not because any one component is new, but because no one has put them together around the patient, at this level of integration, until now. The field has had all the pieces for years. We are finally assembling them.
Why this matters now
Mental health has become the defining health crisis of our generation. One in five adults in the U.S. lives with a mental illness. Since 2002, the share of Americans getting mental health care has grown by a third, and over the same period, the share reporting "excellent" mental health has fallen by nearly as much. The system is working harder and delivering less.
Meanwhile, the science has moved. We now know that chronic inflammation, circadian disruption, nutritional deficits, trauma, and autonomic dysregulation are not metaphors for mental illness, they are mechanisms. We now know that measurement-based care roughly doubles recovery rates in depression, yet fewer than one in five U.S. psychiatrists use it. We now know that integrated care is one of the most consistently validated interventions in the field. And yet it remains the exception, not the rule.
The gap between what the research says and what patients actually receive is the largest it has ever been. That is the opportunity. It is also the indictment. A field this far behind its own evidence is a field ready to change.
What the next decade looks like
I don't think Meru Health Advanced is the end of the story. I think it is the beginning of the shift.
Ten years from now, I believe the phrase "treatment-resistant depression" will feel as dated as "untreatable diabetes" does today. Not because every person will be cured, but because the burden of proof will have moved. If a patient is not improving, the first thing questioned will be the model of care, not the patient.
Ten years from now, I believe comprehensive lab work and metabolic screening will be the standard of care in psychiatry, not the exception. Starting a psychiatric medication without a blood panel will look as negligent as prescribing insulin without a glucose reading.
Ten years from now, I believe the wall between psychiatry and therapy will be gone. The idea that the person prescribing your medication has never spoken to the person doing your therapy will seem absurd. Care will be integrated because fragmented care is, simply, worse care.
And ten years from now, I believe lifestyle medicine, sleep, nutrition, movement, breath, connection, purpose, will be recognized as part of psychiatric treatment, not a wellness add-on. The nervous system does not live in a vacuum. The brain does not heal on medication alone. Psychiatry will catch up to what every other specialty already knows.
Meru Health Advanced is our contribution to that future. We will not be the only ones building it. We intend to be among the first.
One last thing
I think about my brother often. I think about what it would have meant for Peter to walk into a practice where the first thing that happened was a real diagnosis, a lab panel, a metabolic workup, a conversation about his sleep and his life, before anyone reached for a prescription pad. Where the psychiatrist and the therapist were actually on the same team. Where the full arc of his life was treated as part of the medicine, not something to get to after the medication "worked."
Peter didn't get that. Tens of millions of people still don't.
Meru Health Advanced is our commitment to make sure the next Peter does.
If you, or someone you love, has tried the standard path and not gotten better, I want you to know another model exists. It opens to the public today May 6. You can learn more, and join us, at meruhealth.com/advanced
With excitement and optimism,
