In 2017, Susanne Sander discovered the astonishing effect of vitamin D in the successful treatment of her own autoimmune disease with a high dose of vitamin D (Coimbra Protocol®). Since this experience, it has been very important to her to pass on her knowledge in order to protect others from illness and to show autoimmune patients a groundbreaking therapy option. For this reason, she underwent extensive further training and graduated as a vital substance consultant and vitamin D consultant in 2019. Susanne Sander lives with her family in the Lower Rhine region. (Übersetzte Quelle: Verlag / vlb)
