This is Sandra Guerin, a patient with multiple sclerosis who has been on the Coimbra Protocol for 7 years: "Today I managed to climb the mountain of Wayna Pitchu in Peru, 2500 meters of altitude, many steps and I arrived at the top crying from happiness. All this thanks to a great effort and the vitamins... Thanks Dr. Cicero Coimbra and thank you Adalmir Silva for telling me about this treatment.. And people, if you are stil in doubt about Vit D - it's good, yes!!!!" According to Sandra, one of her worst problems with MS was lack of balance; it took her over a year to completely get rid off it but after about 6 months on the protocol she was able to start wearing high heels again. She says: "Today, after 7 years of treatment I'm doing extremely well!"
