Phthalates, BPA, parabens, and organochlorine pesticides are endocrine-disrupting chemicals that mimic, block, or alter natural hormones. These compounds bind to estrogen, testosterone, and thyroid receptors, creating symptoms doctors attribute to aging or stress. Women experience irregular cycles, fertility problems, and early menopause. Men face low testosterone, erectile dysfunction, and metabolic changes. Testing identifies specific disruptors and guides elimination strategies that restore hormonal balance.
