“Many food-contact chemicals include bisphenol A, phthalates, and other toxic substances that promote cancer, impair fertility, and disrupt hormone signaling. Although many of these compounds accumulate in the body over time, some are preferentially excreted in sweat.”

“New audio podcast on refined sugar! Learn how refined sugar has been shown to impair the brain's ability to repair itself after traumatic brain injury, how it causes brain inflammation and memory problems, how it accelerates aging, how it affects hormones, how cutting it out can have profound effects on metabolism in just 1 week, and more!”

“Vasopressin, a pituitary hormone that acts to promote the retention of water by the kidneys and increase blood pressure, is also a social bonding hormone in males — similar to oxytocin in females. Tim recounts his experiences taking vasopressin in college to boost his short term memory.”

“Cortisol, a steroid hormone that participates in the body’s stress response, is produced in humans by the adrenal gland. Several factors influence its release, including stress. Exposure to bright light also promotes the release of cortisol, and, in turn, the hormone drives wakefulness during the daytime hours.”

“In light of growth hormone's effects on bone health, it's possible that sauna use, which boosts growth hormone levels, promotes bone health. In this Aliquot, Dr. Rhonda Patrick discusses the different lifestyle habits that help build and maintain bone health throughout the lifespan.”

“Dr. Patrick also explores fertility trade-offs associated with deliberate heat exposure and exogenous hormones. In a small study of 10 men, twice-weekly sauna sessions for three months altered sperm production and function, with recovery documented during follow-up after sauna use stopped.”

“In this Aliquot, I break down what the research tells us about glyphosate exposure in farming communities versus the general population, explore how it may lead to DNA damage, and share practical strategies for reducing exposure—starting with your grocery list.”

“In a placebo-controlled study of eight healthy adults, adrenaline infusion lowered plasma magnesium, and levels had not recovered one hour later. Investigators proposed a shift into cells after beta-adrenergic stimulation; the study did not measure cortisol, urinary loss, total-body depletion, or clinical deficiency.”

“Dr. Rhonda Patrick reviews alcohol across female and male fertility. She discusses menstrual and ovarian hormones, erectile function, testosterone, semen volume, motility, morphology, and sperm DNA as distinct outcomes; evidence varies by dose and study design.”

“The study results suggest that reducing plastic contact in everyday products, especially food, can lower exposure to some of these chemicals. As endocrine disruptors, they can mimic, block, or alter normal hormone signals, raising concerns not only about cardiometabolic health but also about fertility and reproduction.”
