I've been taking vitamins for my hair and overall health the past 2 weeks and almost each night I've had a nightmare (or at least a disturbing dream). It's always a similar dream and it's to the point where I haven't been sleeping well. I've been taking a basic multivitamin (pharmasure premium women's biomultiple), 1000mg of chlorella, and 300mcg of Biotin (but the multi also has 300 mcg of Biotin, for a combo if 600mcg daily). I've taken multivitamins regularly in my life but never this brand, so I think it has to be the biotin or the chlorella. Has anyone had this problem? I also find that on days when I don't take my vitamins I dont have the nightmare, but it could be a psychological thing since I already think it could be the vitamins. Sorry if this has been discussed before, but some help would be greatly appreciated!!
