Everyone is talking about NAD+, GLP-1 medications, red light panels, and hormone therapy, but almost nobody is explaining, plainly and honestly, what the science underneath any of it actually shows. This book does that. Written in the same simple, direct style as the first book in this series, it walks through thirty-two chapters covering the supplements, devices, and treatments currently driving the longevity and wellness conversation: NAD+ and NMN, creatine and HMB, vitamin K2 and magnesium, hyaluronic acid and collagen peptides, red light therapy and hyperbaric oxygen, hormone replacement therapy for perimenopause and menopause, and the newest names in biohacking culture, GLP-1 drugs, berberine, BPC-157, rapamycin, and methylene blue. For each one, this book asks the same honest question: what does the evidence actually support, what's promising but unproven, and what's mostly marketing? Real side effects get equal billing with real benefits throughout, including the ones that trendy marketing tends to leave out. A dedicated quick-reference chapter maps common physical and mental concerns, from muscle building to brain fog to bone health to hot flashes, to the options this book found best supported, with an honest evidence rating for each. Simple enough to follow at a glance. Thorough enough to hold up in a real conversation with a real doctor, which is exactly where any of this should lead.
