Then why should we have to wait - possibly years to start it. The facebook group Biotin for Progressive MS - has now over 700 members in only 6weeks. Lots of intelligent folk on this global group - and very interesting they all are. A chance to look into the lives of others with progressive ms worldwide. So apart from the Biotin B7 and also Thiamine B1 which also helps so much with fatigue/ energy boosting. Other information has also been very interesting. Not many people have any confidence in their Neuros - so nothing new there!!
