About Complement 1

We are building oncology’s first non-pharma treatment layer, helping patients live longer and better, from diagnosis through survivorship. Clinically validated and delivered daily, Complement 1 provides live lifestyle therapy for people in treatment, recovery, and those at higher risk. Our model brings personalized support in physical activity, nutrition, breathwork, and trauma recovery - tailored to cancer type, treatment, and side effects. Backed by leading oncologists and robust clinical evidence, we achieve 90% adherence and measurable impact: higher treatment completion, fewer side effects and complications, and better quality of life. This is where lifestyle becomes lifesaving.
