In this episode, we explore the fascinating connection between light, your brain, and your gut. Can a single device enhance both of these crucial organs at once? We're diving into the science of how light can be used as a tool for repair and regeneration.

I'm joined by Sarah Turner, CEO of CeraThrive, who brings over 20 years of research in biology, neuroscience, and photobiomodulation—the use of light for therapeutic purposes. Sarah explains the science behind red and near-infrared light, and how it can affect your mitochondria, brain function, and even the structure of water in your body.

Sarah also reveals the surprising link between light, gut bacteria, and brain health. She shows us how restoring microbial balance in your gut can improve everything from digestion to your neurological health.
