A Vision for Vision: From Dublin to Hollywood and on to Austin
Professor John Nolan joined Dr Autumn Smith on the ReThink Health Podcast to discuss over 25 years of research into carotenoids, including lutein, zeaxanthin and meso-zeaxanthin, and their role in supporting eye and brain health. The conversation explores the science behind nutritional supplementation, omega-3s, screen exposure and why quality, independent scientific testing and accurate supplement labelling matter more than ever.
We also discussed the success of the recent international screenings of A Vision for Vision which is now available on Apple TV, Amazon Prime Video and wherever you stream documentaries.
