Marloes Mulder is a Dutch Hashimoto and underactive thyroid specialist who supports women dealing with persistent symptoms, including fatigue, weight gain, brain fog, digestive issues and other lingering complaints. Her work focuses particularly on weight management for women with Hashimoto’s or a sluggish thyroid, without relying on strict diets or exhausting routines.

Through the Self Healing Mastery Method, Mulder encourages clients to take an active role in their wellbeing and support the body’s self-healing capacity. Her approach is intended to complement prescribed medication, not replace it, while helping women work toward improved energy, weight and overall quality of life. The website offers information about her method, client experiences and common thyroid-related concerns, alongside educational resources such as free webinars, masterclasses, checklists and e-books. Visitors can also explore articles, a podcast and YouTube content, find answers to frequently asked questions, or arrange a conversation. Mulder’s services are aimed at women who continue to feel unwell despite treatment or apparently normal test results and want practical guidance for managing their symptoms.
