Eat 5 Pounds A Day of Broccoli OR Do *This* (+ Get Microplastics Out of Tissue Fast?!)

from Boundless Life · host Ben Greenfield

Full show notes: https://bengreenfieldlife.com/marapodcast In this episode, you'll hear the origin story of Mara Labs, a company built around sulforaphane, the active compound found in broccoli that has been studied across thousands of papers covering almost every major chronic disease, and why most people aren't actually getting it from their broccoli supplements. You will discover why the way your broccoli supplement is made determines whether any of it reaches your cells, what dose of the active compound moves the needle on inflammation, detox, and cellular defense, and how a single capsule compares to eating five pounds of adult broccoli a day. You'll also hear something that has not been discussed publicly before: a pilot study showing that this same compound can trigger your cells to release microplastics, those synthetic particles now found in human blood, lungs, and breast tissue, and push them out through your digestive system. David Roberts is the co-founder of Mara Labs. After his wife Mara was diagnosed with breast cancer passed away in 2017, David channeled his experience into building a supplement company grounded in clinical science rather than ingredient trends. Dr. John Gildea is Chief Science Officer and co-founder, with a PhD in molecular biology and over 20 years studying the Nrf2 pathway at the University of Virginia. Author of more than 60 peer-reviewed publications, he developed the stabilization method that made shelf-stable sulforaphane possible and has since led research on sulforaphane's effects on microplastics and cancer stem cells.
