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.

| 0:47.7 | One thing I've come to appreciate over the years is the best products are the ones that simplify your life instead of adding more complexity. |
| 0:54.5 | And that's what I like about our place. They make beautifully designed kitchenware that's |
| 0:58.9 | genuinely functional, which is a surprisingly rare combination. I've personally been spending |
| 1:04.7 | a lot of time cooking at home, especially since I moved to a tiny isolated town in northern Idaho |
| 1:09.2 | without many great restaurants. |
| 1:11.6 | I've found that when your cookware is easy to use, performs well, and doesn't create a bunch |
| 1:15.1 | of clutter, you're actually more likely to use it. One of the products from our place that I |
| 1:19.1 | constantly use is they're always pan, which is designed to replace multiple pieces of cookware |
| 1:24.7 | in a single pan, less clutter in your kitchen, fewer things to dig |
