Have you tried several psychiatric medications and none of them have helped?

Your genetic test can help you and your provider understand why!

In psychiatry, CYP genes control liver enzymes that metabolize many medications, including psychiatric drugs. These enzymes determine how fast or slow medications are broken down in the body, which affects how well they work and the risk of side effects.

• If someone has “fast” CYP genes, medications are cleared too quickly. For example, an SSRI like sertraline (Zoloft) may not reach an effective level, so the person may not feel the benefit. Similarly, opioids can be broken down quickly, reducing pain relief or risk for withdrawal symptoms.

• If someone has “slow” CYP genes, medications stay in the body longer. For SSRIs, this can increase side effects like nausea, fatigue, or anxiety. For opioids, slower metabolism can raise the risk of sedation or accidental overdose.

Different CYP enzymes affect different medications:

• CYP2D6 impacts many SSRIs, antipsychotics, and opioids (like codeine or tramadol).

• CYP2C19 affects SSRIs like citalopram (Celexa) or escitalopram (Lexapro).

By testing CYP genes, psychiatrists can personalize medication selection and dosing. This helps improve effectiveness, reduce side effects, and create a safer, more precise treatment plan for mood disorders, ADHD, or pain management.

If you want, I can make a simple diagram showing MTHFR, COMT, and CYP genes together with SSRIs, stimulants, and opioids—it makes the whole biogenetic picture much easier to understand.

MTHFR VARIANT

In psychiatry, MTHFR is a gene that affects how the body processes folate, an essential B-vitamin that helps make brain chemicals like serotonin, dopamine, and norepinephrine. Folate must be converted into its active form, methylfolate, for the brain to use it effectively. Variations in the MTHFR gene can reduce this conversion, which may affect mood, focus, and response to certain medications.

MTHFR variations are usually classified as moderate or severe:

• Moderate variations may slightly reduce the body’s ability to make methylfolate. People with moderate variants might benefit from low-dose methylfolate supplements, especially if they have mild mood or attention issues.

• Severe variations can significantly reduce methylfolate production. This may contribute to higher levels of homocysteine, a chemical linked to inflammation and cardiovascular risk, and can make mood or cognitive symptoms more difficult to treat. People with severe variants often need higher-dose methylfolate under medical supervision.

Testing for MTHFR helps psychiatrists understand if low methylfolate or high homocysteine might be contributing to depression, anxiety, or poor response to medications, so treatment can be tailored with supplements, nutrition, and appropriate medication choices.

If you want, I can also explain how MTHFR interacts with COMT and other genes to affect psychiatric symptoms in a simple way.

BOTH COMT and MTHFR

Here’s a simplified explanation of how MTHFR interacts with COMT and other genes in psychiatry:

The MTHFR gene affects how well your body converts folate into methylfolate, which is needed to make key brain chemicals like serotonin, dopamine, and norepinephrine. If MTHFR isn’t working well, methylfolate can be low, which may contribute to depression, anxiety, or poor response to medications.

The COMT gene controls how quickly the brain breaks down dopamine and other “catecholamines.” When COMT is very active (fast), dopamine is broken down quickly, which can lead to low motivation or focus. If COMT is slow, dopamine hangs around longer, which may increase sensitivity to stress or anxiety.

When someone has both MTHFR and COMT variations, it can affect brain chemistry in a combined way:

• Low methylfolate from MTHFR may reduce the production of dopamine, serotonin, and norepinephrine.

• COMT variations then influence how quickly the dopamine that is produced is broken down.

Other genes, like CYP enzymes, affect how medications are metabolized. Together, these genes help psychiatrists understand why someone might:

• Have a stronger or weaker response to certain medications

• Be more prone to side effects

• Benefit from nutritional support like methylfolate or B-vitamins

By looking at MTHFR, COMT, and related genes together, psychiatrists can personalize treatment, combining medication, supplementation, and lifestyle strategies to improve mood, focus, and overall brain health.

If you want, I can create a simple visual diagram showing MTHFR, COMT, and CYP interactions for psychiatry—it makes this much easier to understand. Do you want me to do that?
