The Everyday Products
Making You Sick
PFAS, BPA, phthalates, parabens, microplastics, aluminum, formaldehyde — they're in your kitchen, bathroom, and bedroom. Here's what the world's leading health scientists say, and what to use instead.
98%
of Americans have PFAS in their blood
2-5x
more polluted indoor vs outdoor air
240K
microplastic particles per liter of bottled water
85K+
chemicals in products, most never tested for safety
PFAS (Forever Chemicals)
Found In
Non-stick pans (Teflon), stain-resistant fabrics, food packaging
Why It's Harmful
PFAS never break down in your body or the environment. Linked to thyroid disease, cancer, immune suppression, and hormone disruption. Detected in the blood of 98% of Americans.
What the Experts Say
Huberman, Patrick, Brecka, and Greenfield all warn against non-stick cookware.
BPA & Phthalates
Found In
Plastic containers, water bottles, food wrap, canned food linings
Why It's Harmful
Mimic estrogen in your body. Linked to declining sperm counts, infertility, early puberty, obesity, and cancer. Heating plastic dramatically increases leaching. Even 'BPA-free' plastics contain similar compounds (BPS).
What the Experts Say
Huberman dedicated multiple episodes to endocrine disruptors. Patrick cites Dr. Shanna Swan's fertility research. Brecka calls plastic bottles 'chemical castration.'
Microplastics
Found In
Plastic water bottles, plastic cutting boards, tea bags, food containers
Why It's Harmful
Found in human blood, lungs, placentas, and brain tissue. Huberman's episode on microplastics cited studies finding 240,000 particles per liter of bottled water. Long-term effects still being studied but early research is alarming.
What the Experts Say
Huberman, Patrick, and Greenfield all flag microplastics as an emerging health crisis.
Aluminum (in Antiperspirants)
Found In
Conventional deodorants and antiperspirants
Why It's Harmful
Aluminum compounds block sweat glands and are absorbed through skin. Research links to breast cancer and neurotoxicity. Your body needs to sweat — it's a primary detoxification pathway.
What the Experts Say
Brecka and Greenfield strongly warn against aluminum antiperspirants. Huberman notes the evidence is concerning enough to warrant avoidance.
Chemical Sunscreens (Oxybenzone)
Found In
Most conventional sunscreens (Coppertone, Banana Boat, etc.)
Why It's Harmful
FDA studies show chemical sunscreen ingredients are absorbed into the bloodstream after a single application. Oxybenzone mimics estrogen, disrupts thyroid hormones, and damages coral reefs.
What the Experts Say
Published research strongly supports mineral sunscreens with zinc oxide over chemical alternatives that are absorbed into the bloodstream.
Parabens & SLS
Found In
Shampoo, body wash, face wash, moisturizers, cosmetics
Why It's Harmful
Parabens mimic estrogen and accumulate in breast tissue. SLS (sodium lauryl sulfate) strips skin of natural oils and allows other chemicals to penetrate deeper. 'Fragrance' on labels can hide dozens of undisclosed phthalates.
What the Experts Say
Published research links parabens to endocrine disruption. The EWG Skin Deep database is a valuable tool for evaluating product safety.
Fluoride (in Water & Toothpaste)
Found In
Municipal tap water, conventional toothpaste
Why It's Harmful
While low-dose fluoride prevents cavities, high exposure is linked to neurotoxicity, thyroid disruption, and reduced IQ in children. Research presents both sides but notes concerns are legitimate at typical exposure levels.
What the Experts Say
Brecka and Greenfield strongly recommend removing fluoride. Johnson uses hydroxyapatite toothpaste. Huberman discusses the research with nuance.
Indoor Air Pollution (VOCs)
Found In
Furniture off-gassing, cleaning products, candles, air fresheners, mattresses
Why It's Harmful
Indoor air is 2-5x more polluted than outdoor air (EPA). VOCs from furniture, cleaning products, and scented candles include benzene, formaldehyde, and toluene — known carcinogens.
What the Experts Say
Published research supports HEPA air purification and air quality monitoring for reducing indoor pollutant exposure.
Flame Retardants
Found In
Conventional mattresses, couches, children's pajamas, electronics
Why It's Harmful
Chemical flame retardants migrate out of products and into dust you breathe and ingest daily. Linked to endocrine disruption, cancer, and developmental issues in children. You spend 8 hours a night breathing your mattress.
What the Experts Say
Greenfield is the most vocal — warns you spend 1/3 of your life on your mattress. Recommends organic latex/wool mattresses that pass flame tests naturally.
Synthetic Fragrances
Found In
Laundry detergent, dryer sheets, candles, cleaning products, plug-in air fresheners
Why It's Harmful
The word 'fragrance' on a label is a legal loophole that can hide dozens of undisclosed chemicals including phthalates. These contact your skin via clothing 24/7 or you inhale them constantly at home.
What the Experts Say
Huberman, Greenfield, and Brecka all warn against synthetic fragrance. It's considered the #1 hidden source of daily phthalate exposure.
