Metabolic Psychiatry
Weight, mood, sleep, and cardiometabolic risk should be read together.
Medication decisions are stronger when appetite, labs, lean mass, sleep apnea, mood, anxiety, and long-term risk are reviewed in the same plan.
The problem with biohacking is not curiosity.
The problem is when the stack gets bigger and the explanation gets weaker.
A patient can know their HRV, sleep score, glucose curve, testosterone level, supplement schedule, ApoB, caffeine timing, and VO2 max estimate and still not know whether the anxiety is panic, stimulant overload, sleep fragmentation, thyroid disease, low ferritin, under-eating on a GLP-1, bipolar-spectrum activation, or a medication problem.
More data is not the same as a diagnosis.
More interventions are not the same as a plan.
The Fast Answer
- I am not against optimization. I am against guessing with better branding.
- Before NAD, peptides, hormones, GLP-1s, supplement stacks, or stimulant changes, I want the psychiatric and medical differential.
- Sleep oxygen, nutrition status, medication history, thyroid, ferritin, B12, vitamin D, metabolic markers, substance use, and mood safety can change the plan.
- Hormones, peptides, IV therapies, and supplements should not be asked to fix depression, ADHD, panic, burnout, or insomnia without a real evaluation.
- The first high-yield move is often removing noise.
In San Francisco, the patient is often not under-informed.
They are over-instrumented.
The San Francisco Optimization Trap
The San Francisco version of biohacking has a specific texture.
The patient is smart. They read. They test. They track. They have enough disposable income to try the thing before most clinicians have heard of it. They are not always reckless. Many are disciplined, skeptical, and genuinely trying to understand their body.
That is why the trap works.
It looks like investigation.
Sometimes it is.
Sometimes it becomes intervention stacking.
- a stimulant plus caffeine plus nicotine
- a GLP-1 with low protein intake
- testosterone without a clear indication
- thyroid medication because "optimal" sounded persuasive
- peptides from a source no one can explain
- NAD because energy is low
- ashwagandha, magnesium, creatine, L-theanine, 5-HTP, and more because the first few things did not hold
- wearable data that creates more anxiety than clarity
The body becomes a dashboard.
The clinical question disappears.
What I Want Checked First
Before the next intervention, I want the boring, high-yield material.
Not because boring is morally superior.
Because boring is where missed diagnoses hide.
- sleep duration, quality, schedule, snoring, oxygen risk, and morning symptoms
- medication list, dose timing, missed doses, side effects, and prior reactions
- stimulant, caffeine, nicotine, alcohol, cannabis, and psychedelic context
- supplements, peptides, IV therapies, hormones, GLP-1s, and compounds from online or concierge sources
- nutrition, protein intake, weight change, nausea, appetite suppression, and lean-mass risk
- thyroid, ferritin, B12, vitamin D, CBC, CMP, A1c, lipids, and other labs when clinically appropriate
- panic, depression, trauma, OCD traits, ADHD history, bipolar-spectrum risk, psychosis risk, and safety history
- blood pressure, heart rate, palpitations, chest symptoms, fainting, and exercise intolerance
The NHLBI describes sleep deficiency as more than short sleep. It can include poor timing, poor quality, or a sleep disorder that prevents restorative sleep. It can interfere with focusing, learning, reacting, work, driving, and social functioning.
That is not a footnote.
If sleep is broken, the wearable may call it recovery debt.
Psychiatry has to ask why.
Data Is Not Diagnosis
Wearables can be useful.
Labs can be useful.
Symptom trackers can be useful.
But they do not replace the clinical pattern.
Low HRV does not tell me whether the patient has panic disorder, sleep apnea, alcohol rebound, stimulant overuse, overtraining, thyroid disease, inadequate food intake, trauma activation, or a hard week.
Low testosterone does not tell me whether the patient needs testosterone.
A glucose spike does not explain every mood shift.
A low sleep score does not diagnose insomnia, apnea, bipolar activation, restless legs, alcohol rebound, perimenopause, medication timing, or schedule collapse.
The test is a signal.
The diagnosis is the explanation that survives contact with the whole story.
Supplements Can Change The Medication Picture
Supplements are not neutral just because they are sold outside a pharmacy.
NCCIH warns that supplements and medications can interact in ways that increase medication effects, decrease medication effects, or create harmful interactions. NCCIH also notes that supplement products may differ from what was tested in research, may interact with medications, and may contain ingredients not listed on the label.
That matters in psychiatry.
A patient may be taking a supplement that affects sedation, anxiety, blood pressure, bleeding risk, stimulant tolerance, sleep, serotonin load, or medication metabolism. They may not mention it because they do not think of it as medication.
I think of it as pharmacology until proven otherwise.
Bring the bottles.
Bring the list.
Bring the things you take only "as needed."
NAD Is Not An Explanation
NAD and NAD precursors are interesting.
They are not a psychiatric diagnosis.
There is legitimate scientific interest in NAD biology, aging, metabolism, and nicotinamide riboside. There are also small human studies and many larger claims. A PubMed-indexed 2023 review describes nicotinamide riboside as a promising vitamin B3 derivative, but it also points to stability, manufacturing, and research-limit issues.
That is not the same thing as proving that a tired, anxious, depressed, sleepless patient needs NAD.
If someone says NAD helped, I listen.
I still ask the clinical questions.
Was the patient sleeping? Eating? Drinking less alcohol? Coming off cannabis? Reducing stimulant load? Correcting B12? Treating apnea? Leaving a destructive workload? Taking fewer medications? Receiving more attention and monitoring?
The story matters.
Peptides Need More Skepticism Than Hype
Peptides are where biohacking often outruns evidence.
The FDA has specific compounding rules for bulk drug substances. It also maintains information on nominated bulk substances that may present significant safety risks. FDA's page on certain bulk substances lists BPC-157 as a category 2 substance under 503A and describes concerns including immunogenicity risk, peptide impurity complexity, active ingredient characterization, and insufficient safety information for proposed routes.
That does not mean every peptide conversation is unserious.
It means the source, indication, route, safety data, and monitoring matter.
It also means I do not let a peptide story replace the psychiatric differential.
If the complaint is low motivation, anxiety, insomnia, libido change, depression, brain fog, panic, irritability, or ADHD-like focus collapse, the peptide is not the diagnosis.
Hormones Can Help The Right Patient And Hurt The Wrong One
Hormones deserve neither worship nor dismissal.
The North American Menopause Society 2022 position statement says hormone therapy remains the most effective treatment for vasomotor symptoms and genitourinary syndrome of menopause, and that risks differ by type, dose, duration, route, timing, and whether a progestogen is used. The statement emphasizes individualized treatment and periodic reevaluation.
That is the standard I like.
Specific patient.
Specific indication.
Specific risk.
Specific monitoring.
Not "optimize everything."
The Endocrine Society's androgen therapy guideline recommends against diagnosing androgen deficiency syndrome in healthy women and against general testosterone use for broad indications such as general well-being, cognitive health, cardiovascular health, metabolic health, or most sexual dysfunction outside hypoactive sexual desire disorder.
That should slow people down.
Testosterone, estrogen, progesterone, thyroid, and other hormone strategies can change mood, sleep, anxiety, irritability, acne, hair, cycle symptoms, libido, blood pressure, and psychiatric risk.
Sometimes hormones belong in the plan.
Sometimes they are the reason the plan is confusing.
GLP-1s Change More Than Weight
GLP-1 medications can be clinically meaningful.
They can also change the psychiatric picture through appetite, nausea, food intake, alcohol use, sleep apnea risk, weight change, constipation, dehydration, meal timing, and medication tolerance.
If a patient is on semaglutide, tirzepatide, or a compounded GLP-1 and now has anxiety, fatigue, brain fog, irritability, insomnia, low libido, or worsened ADHD-like symptoms, I want the nutrition and dosing story.
The FDA has warned about compounded semaglutide dosing errors, including reports where some patients needed medical attention or hospitalization. FDA also states that compounded drugs are not FDA-approved and are not reviewed for safety, effectiveness, or quality before marketing.
That does not mean every compounded medication is automatically wrong.
It means the risk is not theoretical.
It also means the psychiatric visit should ask about the GLP-1 instead of pretending weight-loss treatment is separate from the brain.
Stimulants And Optimization Culture Can Collide
Prescription stimulants can be appropriate for ADHD.
They can also become part of a stack that nobody is watching.
The FDA identifies prescription stimulants as Schedule II medications with serious risks including misuse, addiction, overdose, and diversion. The same patient may also be using caffeine, nicotine, pre-workout, sleep restriction, GLP-1 appetite suppression, and late-night work.
Then they say, "My medication stopped working."
Maybe it did.
Maybe the dose is wrong.
Maybe the diagnosis is incomplete.
Maybe the medication is being asked to cover sleep debt, under-eating, panic, depression, bipolar-spectrum activation, overtraining, thyroid disease, or a workload that is clinically relevant.
I do not increase stimulants until I know what else is pushing the nervous system.
The Stack Audit
This is how I want the visit to work.
Not "what should I add?"
First, "what is the signal?"
Stack Audit
Before the next biohack, sort the signal
The first useful intervention may be stopping three things.
Or treating apnea.
Or correcting iron deficiency.
Or changing stimulant timing.
Or pausing the online peptide plan.
Or referring for endocrine care.
Or treating actual ADHD.
The stack audit does not assume the answer.
It protects the patient from a prettier guess.
What A Better Visit Sounds Like
The weak question is, "What supplement should I add?"
The better question is, "What is the bottleneck, and what evidence would change the next move?"
That question creates a different visit.
The medication list matters.
The bottles matter.
The wearable data matters, but only in context.
The labs matter, but only if the interpretation is sane.
The mood history matters.
The sleep history matters.
The patient needs someone willing to say, "This is interesting, but it is not the diagnosis."
Getting Help In San Francisco
Horizon Peak Health offers diagnostic optimization in San Francisco for patients whose mood, focus, sleep, medication response, lab data, supplement stack, GLP-1 use, hormone questions, or performance bottlenecks need a deeper medical-psychiatric differential.
The philosophy behind this is laid out in biohacking ethics. If GLP-1s are part of the picture, the guide to semaglutide vs tirzepatide gives useful context. If hormones are part of the story, start with hormone testing for women over 40 and testosterone and women's mental health.
If the stack is growing and the signal is getting worse, bring the stack.
We will sort the pattern.
