About this episode

This episode explores studies on vitamin D's effects on COVID-19, paternal nicotine exposure's impact on child health, and the role of microplastics in neurodegenerative diseases.

In this episode of Behind the Labs , we explore several new studies that reveal how everyday exposures and biological processes can influence human health. We begin with the VIVID clinical trial , which tested whether high-dose vitamin D supplements could reduce the severity of COVID-19 or prevent infection within households. While the study found no meaningful effect on acute illness or transmission, researchers observed a possible small reduction in long-COVID symptoms among participants who closely followed the supplementation regimen. We also discuss research on paternal nicotine exposure, where scientists discovered that nicotine use in fathers before conception altered metabolic pathways in their offspring, suggesting that a father’s health habits may influence the long-term disease risk of future children. The episode then shifts to environmental and neurological health, highlighting a systematic review suggesting that microplastics could contribute to neurodegenerative diseases such as Alzheimer’s and Parkinson’s through mechanisms like inflammation, oxidative stress, and mitochondrial dysfunction. We also cover a study showing that THC intoxication can significantly…
