Description

In this episode of Skin Anarchy, Dr. Ekta Yadav sits down with Dr. Tiffany Libby for a clear, science-forward conversation on supplements, cellular energy, and why NAD biology has become such a focal point in modern longevity discussions. As interest in “aging better” grows, this episode cuts through hype to explore what NAD optimization can—and cannot—realistically do for skin and whole-body health.Dr. Libby brings a rare perspective to the conversation. As a board-certified dermatologist and Director of Mohs Surgery at Brown University Health, her work spans both skin cancer care and cosmetic dermatology, treating patients across decades of life. That long view has shaped her understanding of longevity not as youth preservation, but as maintaining resilience, repair capacity, and function over time—especially in the face of inflammation, environmental stress, and chronic disease.Much of the discussion centers on why supplements, particularly NAD boosters, are having a cultural moment. Dr. Libby explains that this surge reflects a gap in the healthcare system itself—one that prioritizes treatment over prevention. While supplements can offer support, she emphasizes they are not shortcuts. Longevity still rests on fundamentals: sleep, nutrition, movement, stress regulation, and inflammation control.The episode offers a practical breakdown of NAD (nicotinamide adenine dinucleotide), explaining its role in mitochondrial energy production, DNA repair, and cellular defense. As NAD levels decline with age, skin becomes less efficient at repairing damage, producing collagen, and maintaining barrier integrity. Crucially, Dr. Libby explains why NAD itself can’t be absorbed directly—and why precursors like nicotinamide riboside (NR) matter instead.Throughout the conversation, skepticism and safety remain central themes. In an underregulated supplement space, quality, dosing, and clinical validation matter. From a dermatologic standpoint, supporting mitochondrial health may help skin function closer to its biological potential—but only when paired with evidence-based care and realistic expectations.Listen to the full episode of Skin Anarchy to hear Dr. Tiffany Libby unpack the science of NAD, cellular energy, and why longevity begins with supporting biology—not chasing promises.SHOP TRU NIAGENDon’t forget to subscribe to Skin Anarchy on Apple Podcasts, Spotify, or your preferred platform.Reach out to us through email with any questions.Sign up for our newsletter!Shop all our episodes and products mentioned through our ShopMy Shelf!Support the show
