Dr. Stefanie Rau, Global Medical Affairs Manager for Healthy Ageing at Nestlé Health Science, emphasizes that investing in long-term health is a lifelong endeavor. Her work focuses on the critical interplay between musculoskeletal biology, lifestyle, and nutrition, highlighting how mobility profoundly impacts quality of life.

In her role, Dr. Rau collaborates with marketing, R&D, and country medical teams to ensure all initiatives are scientifically sound and ethically aligned with global strategy. A typical day involves reviewing research, developing educational materials, and providing medical guidance, all while prioritizing clear communication and evidence-based information for consumers and healthcare professionals.

The primary challenge, she notes, is translating complex science into accessible, clear messages for diverse audiences. Adapting to evolving science, varying regulations, and increased professional expectations also demands significant flexibility.

Healthy ageing is not something we should postpone until retirement; it’s a lifelong process

A significant misconception, Dr. Rau points out, is that aging begins late in life. The biological processes of aging, including declines in muscle mass and metabolic flexibility, often start in our 30s and 40s. She stresses that preventative actions taken early in life-through nutrition, movement, and lifestyle choices-can dramatically influence long-term function and resilience.

Personally, Dr. Rau defines aging well as maintaining curiosity, a commitment to lifelong learning, and the ability to move freely and independently. She believes that proactive health management, supported by advancements in nutrition and exercise, makes active and healthy aging increasingly achievable.
