Medications and biochemistry
Which depression medication actually fits your biotype?
A "depression" diagnosis alone doesn't say which medication will work. An overview of the five biochemical patterns per the orthomolecular approach, and why the same medication helps one person and burdens another.
Two people can receive the same "depression" diagnosis and the same first medication — and one finds relief within three weeks, while the other's anxiety and insomnia get worse. The difference is often not in the diagnosis, but in the biochemistry behind the symptoms. This article summarizes how biochemical patterns behind depression and anxiety differ according to the orthomolecular approach, which medication classes are most often associated with them in clinical practice — and why testing is a meaningful step before cycling through a fifth medication in a row.
Does this sound familiar?
If this sounds like you, keep reading.
- you've already tried more than one medication for depression or anxiety with mixed (or no) results
- you're curious why the same medication helped a friend but not you
- you want to understand the connections between zinc, copper, histamine, and methylation before deciding on your next step
- you're looking for an overview that doesn't push one specific medication, but explains the underlying principle.
Why a diagnosis alone isn't enough
A diagnosis (depression, anxiety, ADHD) describes symptoms, not their cause. Several different biochemical patterns can sit behind the same set of symptoms — and it's that pattern that determines whether a specific medication helps, does nothing, or makes things worse. The orthomolecular approach works with five main patterns: undermethylation, overmethylation, copper overload, pyroluria, and elevated toxic burden.
These patterns are not a diagnosis in themselves — they are biochemical context that complements a psychiatric assessment and helps explain why medications acting on the same neurotransmitters respond differently in different people.
Five biochemical patterns — an overview table
| Biochemical pattern | What is happening in the body | Test | Vitamin |
|---|---|---|---|
| Pyroluria | Low zinc and B6; impaired production of serotonin, dopamine, and GABA | Pyroluria test (urine) · €99 | Stress Support |
| Histadelia (undermethylation) | Low functional serotonin and dopamine; higher histamine | Histamine test (whole blood) · €149 | Histamin Minus |
| Histapenia (overmethylation) | High or poorly regulated serotonin and dopamine; low histamine | Histamine test (whole blood) · €149 | Histamin Plus |
| Copper overload | Low dopamine with excess norepinephrine, adrenal exhaustion | Cortisol test (saliva) · €149 | Bovine Adrenal Complex |
| Heavy metals (toxic burden) | Burden blocks methylation; neurotransmitter regulation is unstable | Heavy metals test (hair) · €199 | Stress Support |
How medication classes map onto these patterns
In clinical practice, these patterns are often discussed in relation to specific medication classes — not as a prescription, but as an orienting framework that helps explain why people sometimes talk about "the right medication at the wrong time":
- SSRIs — increase serotonin signaling; most consistent with undermethylation, potentially problematic with overmethylation (more on SSRIs).
- Bupropion — increases dopamine and norepinephrine; fits low dopamine, can worsen anxiety with copper overload.
- SNRIs — increase both serotonin and norepinephrine; can help with a combined deficit, can worsen panic with copper overload (more on SNRIs).
- Stimulants — increase dopamine and norepinephrine; effective for ADHD with low catecholamine signaling, problematic with copper overload (more on ADHD medications).
- Mood stabilizers and antipsychotics — act on dopamine and other pathways; important for mania, psychosis, and significant instability, with biochemical context addressed only after stabilization (more on mood stabilizers and antipsychotics).
Sleep as a diagnostic indicator
Insomnia can both mimic and sustain psychiatric symptoms — and different medication classes affect sleep in opposite directions. That's why sleep quality is watched just as closely as mood itself when assessing a biochemical pattern and medication response.
A sequence that makes sense before changing any medication
The recommended approach isn't "stop the medication and try another," but rather: (1) maintain stability, especially during an acute crisis, (2) identify the biochemical pattern using targeted tests, (3) begin targeted nutritional support (zinc, B6, vitamin D, methionine, possibly SAMe depending on the pattern), (4) after some time, reassess how the medication fits the improved biochemical state, (5) give the nutritional changes time to settle in, (6) consider reducing the dose only gradually and under a psychiatrist's supervision.
Medications for depression, anxiety, ADHD, bipolar disorder, or psychotic conditions are never stopped suddenly — this risks relapse, mania, psychosis, seizures, or a significant worsening of mood. With thoughts of suicide, psychosis, mania, or a risk to yourself or others, seek immediate psychiatric help.
Which tests are commonly done when looking for a biotype
This typically involves a combination of: whole-blood histamine, plasma zinc and copper, ceruloplasmin, vitamin D, homocysteine, the SAM/SAH ratio, blood count, a comprehensive metabolic panel, thyroid function, and iron status. PsyLab works with a subset of these markers tailored to the five biotypes we most commonly see in practice in Slovakia.
A practical first step
PsyLab does not diagnose psychiatric conditions and does not decide on medications — any change to medication is decided solely by your treating doctor or psychiatrist. The goal is to give you biochemical context you can bring to your next appointment, better prepared.
1. Fill out the free orientation questionnaire — in a few minutes you'll see which biotype is most likely.
2. Based on the result, consider a targeted test or a 45-minute consultation (€75), where we'll discuss together what's worth addressing first.
