Quick answer: Reducing everyday exposure to environmental chemicals may ease the load on your liver and help protect hormone balance and cellular energy. The biggest wins are filtering water, storing and heating food in glass or stainless steel, choosing fragrance-free personal-care products, cleaning indoor air, and eating more fiber and cruciferous vegetables to support natural detoxification.
Key takeaways
Lowering everyday exposures to environmental chemicals may ease the load on the liver and support hormone balance.
The biggest changes are filtering water, storing and heating food in glass or stainless steel and choosing fragrance-free personal care.

Endocrine disruptors
Many common chemicals mimic or block hormones and can affect thyroid, adrenal and sex hormones, as well as metabolism and fertility. Common examples include BPA and BPS in plastics, phthalates in fragrances, PFAS in non-stick and waterproof products, and parabens.
How your liver processes toxins
In Phase I, enzymes transform chemicals into intermediate forms, a step supported by B vitamins, antioxidants and cruciferous vegetables. In Phase II, the liver attaches molecules that make those intermediates water-soluble, supported by sulfur-rich foods, amino acids such as glycine and NAC, zinc and selenium. In Phase III, compounds leave through bile and urine, which is supported by hydration and fiber.
Practical swaps
Kitchen and food
Filter your tap water, and store and heat food in glass or stainless steel. Replace scratched non-stick pans, wash produce and choose organic for the most-sprayed crops when possible, and choose low-mercury fish.
Personal care
Choose fragrance-free products, read labels for phthalates and parabens, and wash new clothing before wearing it.
Home and air
Use a HEPA air purifier and ventilate your home, and leave shoes at the door. Fix water damage quickly to prevent mold, and test for radon.
For background, see what is toxic load? and how toxins disrupt hormones.
Toxins and healthy aging
Environmental chemicals add oxidative stress that can damage DNA (genomic instability), alter how genes are switched on (epigenetic changes) and strain mitochondria. Lowering exposure is one of the simplest ways to protect these systems.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have known chemical or mold exposures, or if you have hormone or fertility concerns. The same is true if you are planning a pregnancy, or if you want a personalized plan to lower your exposure.
See a medical provider promptly for suspected poisoning; call Poison Control at 1-800-222-1222.

Questions to bring to your clinician
These questions can help you get the most out of your next visit.
Which room or habit would be the most useful place for me to start reducing everyday exposures?
Which changes around my home would be the easiest place for me to start?
Are there simple swaps related to my home that would suit my household and budget?
Would any testing add useful information about my home for me, or is it reasonable to start with simple swaps?

Frequently asked questions
What are endocrine disruptors?
Chemicals that interfere with hormones, such as BPA, phthalates and some PFAS.
What is the easiest way to reduce toxins?
Filter your water, use glass food storage and choose fragrance-free products.
Do I need a detox supplement?
Most people benefit more from reducing exposure and eating fiber and vegetables. Supplements can be considered individually.
Are PFAS in tap water?
They are found in some water supplies. Check your local water quality report and consider a certified filter.
