MUTO stands for evidence-based longevity formulations, developed from cutting-edge cell and aging research. Founded by Dr. Richie Barclay, PhD, MUTO combines clinical studies, pharmaceutical standards, and precise dosages to create a daily foundation for long-term health. At Saunday, we curate MUTO for people and places that understand longevity as a biological process—from individuals seeking systemic support for their resilience and energy to clinics, health spas, retreats, hotels, and specialized longevity centers.
