Build Your Immunity For Life

A practical, evidence-based guide to lifelong immune health.

In Build Your Immunity for Life, Dr. Roderick Mulgan, founder of Lifeguard Health, draws on decades of clinical experience and deep medical knowledge to show how everyday choices—especially in diet and lifestyle—can profoundly influence your immune system. Far beyond the headlines of pandemics, immunity is a lifelong foundation for health and resilience.

This clear, accessible book explores the hidden epidemic of micronutrient deficiencies in modern diets, the science behind immune function, and how simple adjustments—like eating more selenium-rich Brazil nuts, getting better sleep, or understanding how gut bacteria shape your defences—can transform your body’s ability to fight infection. Keeping your hydration on point is also emphasized as essential for optimal immune health.

Whether you’re a health-conscious reader, navigating ageing, avoiding excessive medication, or looking to support your immune system naturally, this book offers concrete, actionable guidance. Having real-time information and making timely decisions are highlighted as key strategies to support and maintain immune health.

Written with wit, warmth, and authority, Build Your Immunity for Life is a must-read for anyone serious about taking charge of their health in a chaotic world.
