Mental health care is changing. At Metabolic Psychiatry Labs, we believe better outcomes start with treating the whole person, not just their symptoms. Founded by Stanford psychiatrist and obesity medicine specialist, Dr. Shebani Sethi, who coined the term metabolic psychiatry and established Stanford's Metabolic Psychiatry Program, our platform is built on a simple but powerful insight: metabolism and mental health are deeply connected. Insulin resistance, inflammation, and mitochondrial dysfunction can directly affect brain function, mood, and cognition. Treating them together is the foundation of our clinical approach. The MetBloom app from Metabolic Psychiatry Labs puts clinician-led, evidence-based care in your hands. ACCESS EXPERT CLINICAL CARE Connect with psychiatrists and metabolic specialists through secure telehealth visits and HIPAA-compliant messaging. TRACK WHAT MATTERS Monitor your symptoms, nutrition, and metabolic data in one place. Our tools are designed to surface meaningful patterns between your metabolic health and how you feel. CONNECTED DEVICES, CONTINUOUS INSIGHTS Patients receive connected monitoring devices that sync automatically with the app, enabling your care team to see real-time data and adjust your care proactively. A CARE PLAN BUILT AROUND YOU Your clinical team brings together psychiatric treatment, metabolic medicine, and lifestyle interventions into a single, coordinated plan that is tailored specifically to you. GROUNDED IN RESEARCH Our clinical model draws on research from Stanford, Harvard, UCSF and other leading academic institutions examining the links between metabolic and mental health. CONDITIONS WE SUPPORT Depression Anxiety Bipolar disorder Schizophrenia OCD Eating disorders Treatment-resistant symptoms Metabolic side effects from psychiatric medications WHO THIS IS FOR Metabolic Psychiatry Labs serves patients who are looking to combine lifestyle based approaches to traditional models for better outcomes, for caregivers wanting to support a loved one's mental health journey, and for those seeking a more comprehensive, spiritual and metabolism-informed path to their care. Metabolic Psychiatry Labs is a telehealth clinic. All care is delivered by licensed clinicians. The MetBloom app requires an active patient relationship with Metabolic Psychiatry Labs.

FEEL GOOD AFTER EVERY MEAL Living with histamine intolerance or MCAS means every food is a question mark. HistaScan gives you a clear, instant answer โ€” just scan. SCAN ANY FOOD, THREE WAYS โ€ข Barcode โ€” check any packaged product in seconds โ€ข Ingredient label (OCR) โ€” snap the label for an instant breakdown โ€ข Dish / plate photo โ€” analyze a whole meal from one picture HISTAMINE, OXALATES AND SALICYLATES Most apps only look at histamine. HistaScan rates all three, because people with MCAS frequently react to oxalates and salicylates too. KNOW YOUR DAILY LOAD Histamine is cumulative โ€” it's the total across the day that matters, not any single food. HistaScan tracks your daily histamine load against an allowance tuned to your sensitivity, so you can see how much headroom you have left. ALWAYS EXPLAINS WHY Every rating names the exact ingredients behind it, in plain language, with a lower-histamine swap when a trigger appears. No colour codes you have to guess at. BUILD YOUR SAFE-FOOD LIST Save the foods that work for you and pull them up instantly at the grocery store. TRACK SYMPTOMS, FIND YOUR TRIGGERS Log meals and reactions in one private timeline. Note antihistamines, DAO enzyme, and severity to spot the patterns behind your flares. DESIGNED FOR YOUR CONDITION Built for histamine intolerance, MCAS, mast cell activation, and elimination diets โ€” and helpful for FODMAP, dairy, gluten, lactose, and fructose sensitivities too. PRIVATE BY DESIGN No account required. Your scans, diary, and reaction logs stay on your device. Free to start. Premium unlocks unlimited scans, instant meal-photo analysis, and advanced MCAS symptom insights. HistaScan is an educational tool and not a substitute for professional medical advice. Always consult a qualified healthcare provider.
