You can't avoid what you can't see

Every day, you're exposed to environmental chemicals — through the food you eat, the water you drink, the air you breathe, and the products you use. Plastics, pesticides, industrial compounds, and household chemicals accumulate silently in your body over time.

~5g of plastic per week
A WWF-commissioned study by the University of Newcastle found that people may ingest approximately 5 grams of microplastics weekly — roughly the weight of a credit card. The biggest source? Drinking water, both bottled and tap.

This toxic burden has been linked to a wide range of symptoms that many people experience but can never fully explain:

🔋
Persistent fatigue
🧠
Brain fog & memory issues
😣
Recurring headaches
😶‍🌫️
Mood changes
🤢
Nausea
🫁
Respiratory problems
👁️
Eye irritation
Neurological symptoms

27 environmental toxicants, one urine sample

Using the clinically validated TOXDetect panel by Mosaic Diagnostics, we screen for metabolites from the most common classes of environmental chemicals — the ones you encounter every single day.

Phthalates

Endocrine-disrupting chemicals found in food packaging, toys, shampoo, and vinyl flooring. Exposure is virtually universal.

MEP, MBP, MEHP, MEOHP, MiBP

Bisphenols

Used in plastics and resins — food containers, water bottles, dental sealants. "BPA-Free" alternatives like BPS may carry similar risks.

BPA, BPS

Volatile Organic Compounds

Found in household products, building materials, paints, vehicle emissions, and cigarette smoke. Easily inhaled or absorbed.

Xylene, Styrene, Benzene, Vinyl Chloride metabolites

Pesticides

Exposure through contaminated food, water, air, and soil — from agricultural and household use.

Glyphosate, Atrazine, 2,4-D, 3-PBA, DEP

Parabens

Preservatives widely used in cosmetics, skincare, and personal care products. Absorbed through the skin daily.

Methylparaben, Ethylparaben, Propylparaben, Butylparaben

Other Chemicals

Additional toxicants that contribute to chronic toxic overload through multiple exposure routes.

Oxybenzone, Perchlorate, Diphenyl Phosphate

Your liver and kidneys, closely monitored

Because the liver and kidneys are the body's primary detoxification organs, we include full clinical panels at both timepoints — reviewed by a physician — to ensure your safety throughout the study.

🫀 Liver Function Panel

  • Bilirubin
  • ALP (Alkaline Phosphatase)
  • ALT (Alanine Aminotransferase)
  • GGT (Gamma-Glutamyl Transferase)
  • Total Protein, Albumin & Globulin

🔬 Kidney Function Panel

  • Creatinine & eGFR
  • Urea & Sodium
  • Urine Microalbumin
  • Albumin:Creatinine Ratio (ACR)
  • Urine Creatinine

What you get — at no cost

Participants receive a comprehensive health assessment package that would normally cost hundreds of pounds — entirely free of charge.

01

Full Toxicology Report

See exactly which environmental chemicals are present in your body, with two snapshots — baseline and 60 days later — so you can track changes over time.

02

Liver & Kidney Health Check

Complete hepatic and renal blood panels at both timepoints, giving you clinical insight into how your detoxification organs are functioning.

03

Physician-Reviewed Results

Every blood result comes with a clinical interpretation from a physician — not just raw numbers, but what they actually mean for you.

04

Home-Based Testing

A qualified phlebotomist visits your home for blood draws. Urine samples are collected with a simple home kit. No clinic visits needed.

05

Actionable Health Insights

Understanding your toxic burden can guide practical lifestyle changes — from choosing different products to adjusting diet and hydration habits.

06

Contribute to Research

Help build vital data on environmental chemical exposure in the UK population — your participation contributes to a growing and important field of health science.

How it works

1

Apply & Get Accepted

Send us a message to express your interest. We'll confirm your eligibility and walk you through everything. Only 20–30 spots are available.

2

Baseline Testing (Day 0)

A phlebotomist visits your home for a blood draw. You also provide a urine sample using a simple collection kit. We record lifestyle variables for accuracy.

3

60-Day Study Period

Continue your daily routine with MasterPeace® use as directed. The study evaluates changes in your environmental toxic burden over this period.

4

Follow-Up Testing (Day 60)

Repeat the same blood and urine tests. Compare results against your baseline to see how your toxic burden and organ function have changed.

5

Receive Your Full Report

Get your personal toxicology and organ function results — with clinical interpretation — giving you a detailed picture of your internal health.

Study designed by Caroline Mansfield · April 2026

All testing is performed through accredited third-party laboratories. Hepatic and renal function results include a physician's clinical interpretation. The TOXDetect panel is provided by Mosaic Diagnostics, using LC-MS/MS technology.

Contextual variables — including hydration, alcohol intake, exercise, medications, and recent illness — are recorded at each timepoint to ensure data reliability.
