Physician – Specialist in Integrative Medicine, Nutrition and Health Optimisation

Dr Rozenn CASTERA, a physician with over 30 years of experience, has built deep expertise in the service of a global, preventive and personalised approach to medicine. Her conviction: the everyday symptoms — fatigue, weight gain, hormonal disorders, skin alterations — are rarely isolated. They are most often the expression of underlying biological imbalances that have been insufficiently explored, yet which can be identified, corrected and prevented. 

Her objective: to help each patient understand the root causes of their imbalances, act on the most relevant levers, and restore optimal health — without excessive constraints or unrealistic changes. 

Specialized in integrative medicine, nutrition, anti-ageing medicine and homeopathy, Dr CASTERA offers a rigorous approach based on in-depth biological exploration — blood, urinary and functional tests — combined with a thorough analysis of lifestyle. This approach allows her to develop targeted, progressive and lasting correction strategies, tailored to the uniqueness of each patient. 

She accompanies her patients in areas as varied as weight and metabolic regulation, hormonal balance (menopause, chronic fatigue, dysregulations), improvement of energy, sleep and concentration, skin quality and prevention of ageing, as well as the global optimization of health and well-being. 

Because every patient is unique, Dr CASTERA places particular importance on the quality of listening and thetherapeutic relationship. Each support program begins with an in-depth consultation to define a clear, personalized and evolving strategy. Her vision is clear: explore, correct, optimize — to allow each person to rediscover vitality, balance and serenity in every dimension of their life. Dr CASTERA offers her consultations via international telemedicine, in French, English and Spanish.
