I've been taking 5000ug of biotin per day for some years. I'm unsure quite why, maybe I was just playing copycat on some OMS meme years ago. It's past time that I grokked the OMS bible to ascertain whether this is wise. Back then, 10 years ago, almost all of my hair disappeared from neck down. Since then some has returned, whether that's attributable to biotin or not I have no idea. As to help with symptoms, that I can never tell, even with OMS itself, as I have no me-without-OMS (nor ever will have) to compare with. My hunch is that some of these situations (taking some a treatment, supplement, therapy, etc) are more about mind-body, placebo-nocebo, etc than anything physiologically real. Not that I'm agin that at all, as long as there's no physical, fiscal or other harm done. Indeed, if I could do something innocuous that triggered in me the maximum MS healing forces (together with curbing all pro-MS forces too), that would be ideal. Though my prejudice would be for that to come from sources that have nothing to do with the medical trades, pharma, witch doctors who are in it for money, or any hocus-pocus. As to the thrust of the question, assuming that's with regard to whether biotin help with MS, I don't know. And in general where there's scant justification or relevant evidence, I'd prefer to be as clean and free of all treatments as nature made me (ie. zero drugs or artificialities, of any sort). But perhaps worth experimenting, who knows whether taking biotin might trigger magic healing in you (this last quip instantly retracted should there emerge sound reason to consider biotin worse than innocuous).
