Solaray Mega B-Stress -- 120 Vegetarian Capsules
I added these to my daily vitamins/vit C/etc. mix a few years ago. I've noticed if I stop taking these, I definitely get sick more easily; I've had this happen twice when I ran out and didn't think it would matter (it's "just" vitamin B, after all!). I noticed when I ran out of my multi-vitamin it seemed to make no difference in how I felt or my immune system, so I eliminated those and just take these, Vitamin C, and some other supplements for my particular health issues.
