My guests on today's show—Dr. James Fadiman and Jordan Gruber—just released the brand new book Microdosing for Health, Healing and Enhanced Performance, which is the first comprehensive book on microdosing, using new research and extensive reports from individuals to describe the possibilities of the practice.
On this podcast, we dive into all things microdosing, with never-before-revealed practical tips on how to do it safely and effectively.
Microdosing—a topic rife with controversy—is now proving to be a safe and powerful approach to a wide range of health conditions and enhanced performance. Partly responsible for modern microdosing’s development and current popularity, James and Jordan answer hundreds of questions, blending extensive research with detailed personal accounts from contributors worldwide. The book also contains wide-ranging microdosing history, research, and science.
In this show, you'll discover how to microdose successfully to:
- Alleviate symptoms of depression, ADHD, chronic pain, and long COVID
- Enhance your focus, mental acuity, and physical abilities (including sports)
- Help taper off pharmaceuticals, especially antidepressants and stimulants
- Improve food habits, sleep, and relationships
- Become more aware of personal habit patterns, others’ feelings, and natural surroundings
- Reduce stress and anxiety
- Help over 30 specific health concerns
James Fadiman, Ph.D., has been professionally involved with psychedelics for over 60 years. He developed modern microdosing, including the use of protocols, specific dose ranges, and time off. He is the author of The Psychedelic Explorer’s Guide and (with Jordan Gruber) Microdosing for Health, Healing, and Enhanced Performance. He has taught at three universities, ran his own management consulting firm, co-founded the Institute of Transpersonal Psychology, and served as the director of the Institute of Noetic Sciences.
Jordan Gruber has a JD from the University of Virginia School of Law and both a philosophy BA and public policy MA from Binghamton University. After practicing law at Cooley Godward, specializing in IP law at NASA’s Moffett Field, and working at GNOSIS Magazine, “The Practical Wordsmith”—a writer, ghostwriter, and editor—emerged. As such, Jordan has co-created cutting-edge works on everything from financial services to health, wellness, psychology, and spirituality. His editorial abilities, collaboration skills, and wide-ranging knowledge reliably led to easy-to-read books woven with astute detail.
Jordan and James (Jim) have been close friends since 1990 when Jordan sought advice on his Enlightenment.Com project. Jordan contributed to Jim’s 2011 book, The Psychedelic Explorer’s Guide, and in 2020, their co-authored book on healthy multiplicity—Your Symphony of Selves: Discover and Understand More of Who We Are (Inner Traditions)—debuted. Since then, both Jordan’s and Jim’s attention has turned increasingly solely toward Microdosing for Health, Healing, and Enhanced Performance (St. Martin’s Press, 2025).
