Why This Test Is Different

1. A complete view of your brain–body communication

By measuring both neurotransmitters and hormones, this test reveals how stress, sleep, mood, and hormonal balance influence each other.

2. Objective clinical insight—not guesswork

Urinary and saliva biomarkers provide quantitative, real, testable data to guide treatment plans—far more accurate than symptoms alone.

3. Personalised treatment recommendations

Your report includes complimentary doctor-reviewed clinical comments explaining your results (valued at £350)

• Which biomarkers are too high or too low
• How this affects mood, stress, sleep and behaviour
• Evidence-based suggestions to help restore balance

4. Easy, non-invasive sample collection at home

Collect 4 dried urine samples throughout the day plus saliva samples. No blood draws. No clinic visits.

5. Fast, clear results

Results are emailed within 3–5 working days after the lab receives your samples.
Your result report includes:

• Graphs and charts
• Reference ranges
• Detailed clinical commentary
• Next-step guidance

Who Should Take This Test?

This test is beneficial if you experience:

Mental & Emotional Symptoms

• Anxiety or depression
• Irritability or mood swings
• Panic attacks
• Brain fog or poor focus
• ADHD-like symptoms

Sleep Issues

• Trouble falling asleep
• Waking frequently
• Non-restorative sleep
• Daytime fatigue

Hormonal Symptoms

• PMS or PMDD
• Perimenopause or menopause symptoms
• Low libido
• Weight gain
• Infertility symptoms

Stress & Burnout

If you have three or more of these symptoms, neurotransmitter and hormone testing can provide essential clarity.

Why Neurotransmitter Imbalance Matters

Neurotransmitters regulate:

• Mood & emotions
• Sleep & alertness
• Appetite & cravings
• Cognition & memory
• Motivation & reward pathways
• Autonomic functions (heart rate, digestion, blood pressure)

When these chemical messengers are imbalanced, you may experience:

• Depression
• Anxiety
• Insomnia
• ADHD symptoms
• Low libido
• Fatigue
• PMS/PMDD
• Digestive issues
• Behavioral concerns (children & adults)

Testing helps identify which pathway is dysregulated so treatment can be targeted—not trial and error.
