Phytoestrogens are naturally occurring plant compounds that mimic the hormone estrogen in the human body. These compounds can bind to estrogen receptors, potentially influencing the hormonal balance, particularly in men. Phytoestrogens are found in a variety of foods, most notably in soy products, flaxseeds, and certain grains and vegetables. For those looking to increase testosterone levels or maintain hormonal balance, it is essential to be aware of and manage the intake of phytoestrogens.

Endocrine disruptors are chemicals that can interfere with the endocrine (hormone) system. These substances can mimic, block, or alter hormone levels, leading to a variety of health issues. Endocrine disruptors can affect several hormonal functions, including thyroid regulation, insulin production, and reproductive health. Long-term exposure to these chemicals has been linked to numerous health problems, including developmental, reproductive, neurological, and immune issues in both humans and wildlife.
