The doctor treating you literally wrote the book on ketamine medicine.
Now available for ketamine clinicians worldwide
Dr. David Mahjoubi has spent 17 years administering ketamine — first as a hospital anesthesiologist, then as one of the very first physicians in the United States to prescribe at-home ketamine therapy for depression, anxiety, PTSD, and chronic pain. As President of the American Board of Ketamine Physicians, he’s now published the definitive clinical manual that other ketamine doctors across the country use to guide their own practices.

The Manual
The Art and Science of Ketamine Medicine is the protocol manual Dr. Mahjoubi wrote for the medical community after more than a decade of running infusion clinics and pioneering at-home ketamine therapy. It covers everything a serious ketamine physician needs to do this work properly — patient screening, dosing protocols for depression and anxiety and PTSD and chronic pain, drug interactions to watch for, side effects to manage, and the operational discipline that distinguishes a sustainable practice from a careless one.
It is now used as a reference by ketamine clinicians across the country.

What this means for you
01
Direct expertise, not a rotating roster
At most telehealth ketamine companies, you’re matched with whichever clinician is on call. At NutraBrain, your prescribing physician is the doctor who literally wrote the protocol your treatment is based on. There is no expert behind the expert.
02
Protocols refined across thousands of patients
The dosing strategies in your treatment plan aren’t from a generic playbook. They’re the same protocols Dr. Mahjoubi has personally titrated and adjusted over more than a decade of clinical practice — and that he’s now teaching to other ketamine physicians.
03
Five formulations, your specific needs
The book describes nasal spray, troche, rapidly dissolving tablet, sublingual droplet, and the exclusive ketamine + oxytocin combination — all the same formulations available through NutraBrain. Your treatment is calibrated to your symptoms and history, not a one-size-fits-all subscription box.
04
Honest medicine
The manual is candid about who ketamine helps, who it doesn’t, and what side effects to expect. That’s the same honesty you get in your video consultation. No miracle promises, no hard sell — just careful clinical guidance from a physician who has spent his career on this work.
I treated patients for treatment-resistant depression, post-traumatic stress disorder, severe anxiety, suicidality, alcohol use disorder, complex regional pain syndrome, fibromyalgia, refractory migraine, and a long tail of less common indications. Some of those patients had been suicidal for years; many of them are alive today because of these infusions.
