raynaud's syndrome
"I do not have circulation issues, but I do have Reynauds likely as a result of Lupus.  I also have BP on the low side. I take this once a day in the winter and have not noticed any of the side effects mentioned (headaches, dizziness) but my already-bad leg/foot cramps get much worse -- sometimes debilitating. To counteract that, I take magnesium in the form of Calm at night...my cramps are much better!! I guess I recommend both...
I am wondering what time of day is best to take this..I can have sleep issues and don't want to make that worse."
