John A. Richardson, Jr.'s journey with apricot seeds began in his childhood, where they were a staple in his daily diet. As he transitioned into adulthood, he developed a profound dedication to spreading awareness about the potent health benefits of Vitamin B17, a key component found in these seeds.

His network of close friends was significantly influenced by his connection with G. Edward Griffin, a lifelong friend of his father, Dr. John A. Richardson, MD. who was a visionary in the realm of nutritional health and alternative treatments. Despite his pioneering efforts in healthcare, Dr. Richardson faced adversity, losing his medical license, his freedom, and eventually, his life.

Driven to honor the legacies of his father and G. Edward Griffin, John founded Operation World Without Cancer—a global humanitarian initiative promoting natural, metabolic solutions to abnormal cells, with the vision of making cancer as rare as scurvy in our lifetime. As Chief Visionary Officer, he advances his father’s mission to educate the world about Vitamin B17 and its potential. In 2024, the 50th anniversary of the publication of G. Edward Griffin's landmark book, World Without Cancer: The Story of Vitamin B17,  marked a renewed commitment to exposing the science, history, and suppression behind this powerful nutrient.

As a recognized leader in alternative cancer care, John also serves on the Global Wellness Forum Council on Healing Centered Cancer Care, which represents a deeper model of cancer care rooted in systems healing, integrative medicine, and patient sovereignty Through this role, he supports the Forum’s broader mission to unite and empower grassroots organizations, thought leaders, and activists around the world in promoting health freedom, truth, and transparency.

John is also the Founder of Richardson Nutritional Center. RNC promotes wellness and healthy living through the use of safe and effective dietary supplements that support the body's natural healing processes, including products that contain premium Vitamin B17. RNC is committed to empowering individuals to take control of their health and well-being with confidence.

John and his wife, Kristina Richardson, have 11 children. Several of the Richardson children are already carrying forward their grandfather's legacy, either working in the family business or pursuing education in naturopathic or nutritional health.
