Boost your body's internal ability to defend, perform, and restore with this guide to the 21 most common adaptogens and their healing properties from the team behind Four Sigmatic.

Are you suffering from chronic fatigue, anxiety, digestive, or autoimmune issues? Or are you seeking a simple way to bring whole-body health into your life with a food that is easy to integrate into your everyday routine with no muss, no fuss?

Welcome to the world of adaptogens: nutrient-dense, calorie-sparse superfoods that have been clinically proven to help your body:


- defend your immunity and gut health,
- perform through your cardiovascular and respiratory systems,
- and restore balance through your neuroendocrine system.

By definition, adaptogens are nontoxic, nonspecific (meaning they build adaptive energy rather than exerting a specific effect), and normalizing (meaning there's a balancing bidirectional effect on physiological function). Tero Isokauppila, founder of Four Sigmatic, and registered herbalist Danielle Ryan Broida guide you through the scientific mechanisms and health benefits of the 21 most powerful species of adaptogens, from ashwagandha to chaga to turmeric.

Complete with client case studies and a shopping guide, Healing Adaptogens will educate, inform, inspire, and delight, giving you the tools you need to elevate your daily routine with adaptogens.
