Videobeschreibung zu circadianem Licht, Melatonin und Pinealpeptid-Forschung

Your melatonin really does decline with age — but taking a melatonin supplement doesn't fix the biological clock behind it. In this video, I break down how your master clock and pineal gland control deep sleep, why the rhythm drifts after 40, what the research on pineal peptides like Epitalon and Epithalamin really shows (with honest evidence levels), and a free 24-hour light protocol to reset your circadian rhythm. 🔗 Explore peptides with a physician (EllieMD): elliemd.com/product/epitalon?bp=drkristi Disclosure: I am a brand partner with EllieMD and receive a small commission if you use my link.
