hi gago,i would say don't worry too much,my brother just took his vest,and he is 26 yrs old.i think exercise is more important,and salt from sea,since she lives at seaside.adeks are vitamins a,d,e, and k.and no one knows how the disease goes,everyone is unique,may she is a mild case for many many years.so don't worry and stay calm...
