Anna Gellert is a nutritionist (M.Sc. in Ecotrophology) and expert in personalized, cycle-based, and sports-oriented nutrition with a focus on women's health and performance optimization. As a partner at Quest Vitality, she advises companies and clients from the worlds of sports and business. As a mother of twins, she also brings a practical perspective to the challenges of modern nutrition—because she knows that theory and everyday life are not always the same. Her approach combines scientifically based nutritional recommendations with everyday practicality and psychological aspects such as mindfulness and enjoyment—with a clear focus on performance, health, and quality of life.
