In Your Optimal Health**, neuroscientist Dr. Émilie Steinbach unlocks the secrets of lasting energy, focus, and resilience with a simple yet powerful 10-step daily protocol. Blending the latest science with practical guidance, she shows how small, consistent habits in nutrition, sleep, movement, and mental balance can dramatically transform your well-being. Whether you want to sharpen your mind, strengthen your body, or boost your mood, this book offers clear, accessible strategies rooted in cutting-edge research.** More than just a guide to “healthy habits,” the book emphasises how small, consistent choices can reprogram biological systems to improve energy, focus, emotional balance, and long-term resilience. Steinbach combines cutting-edge discoveries on the gut–brain axis, mitochondria, and circadian rhythms with simple, practical advice for everyday life. Far from quick fixes or fad advice, Steinbach’s approach draws on her expertise in neuro-nutrition and integrative biology to reveal how your brain and body thrive when supported by the right routines. With inspiring insights and actionable tools, Your Optimal Health is both a handbook for everyday vitality and a roadmap to a longer, healthier life. Your Optimal Health is a bestseller in France selling 60,000 copies in its first six months after publication.
