Ep117: PEMF Therapy & Red Light Therapy: Benefits, Differences & How They Work With Andy Smith

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews Andy Smith, PEMF therapy educator and founder of CELLER8. Andy explains how pulsed electromagnetic field (PEMF) therapy and red light therapy interact with the body at the cellular level – and why these technologies may support energy, sleep, recovery, pain management, and overall wellness.

Andy also shares the personal health crisis that introduced him to PEMF therapy nearly 15 years ago. After emergency surgery and months of recurring infection, antibiotics, pain, and declining mental health, he discovered a therapy that he believes helped him regain his health and ultimately inspired a new career. Together, Dr. Wentz and Andy explore the differences between PEMF and red light therapy, how to incorporate these tools into a realistic wellness routine, and what consumers should know before investing in an at-home device.

What you’ll learn in this episode:

How red light therapy may support cellular energy and whole-body healing. Andy explains how red and near-infrared wavelengths interact with the mitochondria and may help the cells produce more ATP – the energy they need to carry out essential functions. He also clarifies why red light and near-infrared light have different applications, from supporting skin health to reaching deeper tissues.

What PEMF therapy is – and how it differs from red light therapy. Andy breaks down how pulsed electromagnetic field therapy uses low-frequency electromagnetic fields to interact with the body. He explains why PEMF can travel through the body differently than light-based therapies and why he views it as a foundational tool for supporting cellular health.

How a frightening health crisis led Andy to discover his purpose. Andy shares how an unexplained infection, emergency surgery, and six months of recurring symptoms left him physically and emotionally depleted at age 25. After trying PEMF therapy during his recovery, his experience inspired him to leave his family business and dedicate his career to making the technology more accessible.

Why PEMF may complement other wellness therapies. Andy discusses why supporting cellular energy and membrane function may help the body make better use of nutrients, supplements, red light therapy, and other modalities. He also shares how PEMF can be paired with practices such as breathwork or incorporated before therapies like hyperbaric oxygen treatment.
